Balance may be symmetrical geometrical or asymmetrical. RHYTHM Rhythm is achieved through colour and gradation size of flowers The colour may be darkest at focal point and gradually lighter at the rims.
Line may be created by repetition of similar flower colours, textures or shapes. FORM Flower and foliage add a visual quality that is important in developing, harmony, creating rhythm and establishing focal point. It should be suitable for flower arrangement. It should be capable of holding water.
It should be stable enough to support the weight. It originated in the 6th century in Japan as a religious offering at Buddhist temples. However history says that the actual origin of Ikebana is China from where it is believed to have spread to India and then Japan. In Japan, Ikebana was popular among the aristocracy and the samurai class.
To reach a state of peace of mind and a state of concentration before going to battle, the samurai would perform both Ikebana and Tea Ceremony, which helped to purify their heart and mind. By the 16th century, Ikebana had become a Zen practice.
One becomes quiet when one practices Ikebana. One becomes more patient and tolerant of differences, not only in nature, but also more generally in other people. Its heart is the beauty resulting from colour combinations, natural shapes, graceful lines, and the meaning latent in the total form of the arrangement. The three main components of Ikebana: Heaven, Man and Earth. In Ikebana empty space plays an essential part of the arrangement.
The elements placed asymmetrically, are given emphasis by the spaces. Thus, the totality of a well-done arrangement brings about a state of serenity and peace to the viewer. It lacks focal point. Equilateral triangle-shaped arrangement - will be equally as tall as it will be wide. The tallest flower is placed exactly in the centre of the container. A short-stemmed flower is placed at the front of the arrangement to form the focal point.
The triangular arrangement is completed by filling in with the remaining flowers and foliage. Asymmetrical triangle - height and width of the arrangement will be altered. Line flowers or foliages are used to form the outline Gladiolus, snapdragons, flat fern, and palm fronds are commonly used.
The height of the arrangement is established first. The curved foliage is placed to the side usually left of the centre. The focal point is located directly beneath this point at the base of the arrangement. The S shape is separated into two elements, with the upper curve consisting of two-thirds the height of the total design. The focal point is often depicted by a cluster of grapes gracefully dangling over the rim of the container.

Allied Publ. Plant pathologists commonly refer to such disorders as non-parasitic, abiotic, physiological, or noninfectious diseases.
These are mostly caused by adverse environmental, chemical, or soil factors that result in abnormal plant growth and development. A non-infectious disease is not contagious, therefore it does not spread from plant to plant and increase over time. However, non- infectious diseases can be serious when plants are uniformly exposed to a high level of the stress factor. In some cases, normal growth and development may return once the stress or adverse environmental condition is removed or corrected.
Some common non- infectious diseases of vegetables has been discussed in this chapter. Affected tubers develop an intense, blackish, irregular discoloration in the center. The blackened tissue is initially firm, but later becomes soft and watery. Management- Growers should avoid storing potatoes in closed containers or bins, or in deep piles that lack adequate ventilation.
Storage temperatures should be reduced as soon as possible after harvest. Potato should not be grown on land that is subject to flooding or has poor drainage. This disorder is aggravated by dry storage conditions; harvesting during cold soil conditions can induce growth cracking.
Thumbnail cracking appears as if a thumbnail has been pressed into the skin of the potato; Tubers may also split from internal pressure following excessively rapid growth, which usually occurs along the longitudinal axis of tuber. Management- Tubers should be handled as little and as gently as possible from harvesting to storage. Following storage, the tubers should be warmed prior to handling. Tubers should be stored at high humidity to minimize thumbnail cracking. HOLLOW HEART- most severe under conditions that favor rapid tuber enlargement, such as unbalanced fertilization, dry soil conditions followed by high moisture levels, and soils with a low organic matter content, especially those that are well-drained and in areas where the annual rainfall may exceed mm; Potassium deficiency also has been implicated in this disorder.
Tubers with hollow heart lack external symptoms. They usually are detected only after the potatoes have been cut in half. Initially, affected tubers exhibit a brown area at or near the center. Close and regular spacing of hills, maintenance of uniform soil moisture levels, adequate potassium fertilization, and the planting of highly susceptible cultivars, such as Kennebec, closer together in the row will reduce hollow heart incidence.
Blossom drop has been associated with environmental stresses and improper soil fertility that inhibit flower pollination. Prolonged period of high temperature above F wind during the day are associated with blossom drop, night temperature outside the range of F inhibit effective pollination. Management- Following recommended fertilizer rates for tomatoes reduces blossom drop, shading and overhead watering can reduce temperature, but their value decreases under prolonged periods of high temperature.
Symptoms begin as small, tan, water-soaked area near the blossom end of the fruit. The spot enlarges, darkens, and becomes sunken and leathery. Affected fruit often ripen prematurely and are prone to invasion from secondary, fruit-rotting pathogens. High temperatures and wind, widely fluctuating water availability, and drought stress promote blossom-end rot.
Conversely, excessive soil moisture for prolonged periods can damage the root system and its ability to uptake calcium. Management- Use of nitrate forms of nitrogen fertilizer, rather than ammonium forms which can interfere with calcium uptake, may reduce blossom-end rot. Maintain adequate and uniform levels of soil moisture though irrigation, particularly during periods of drought and high temperatures.
Applications of agricultural lime or gypsum should be made prior to transplanting. Foliar sprays with soluble forms of calcium are of little value because of poor absorption and movement to fruit where it is needed. Affected fruit are often kidney-shaped, but can also be distorted into other shapes. Bands of brown scar tissue may form between swollen areas of the fruit.
Cavities or indentations extend deep into the fruit. Affected fruit ripen unevenly and market quality is reduced. Catface occurs most often on the first-formed fruits. Catface is the result of abnormal development of the pistil of the flower, which eventually forms the fruit. Management- Little can be done to control catface other than avoiding highly susceptible, large-fruited varieties and keeping phenoxy herbicide away from tomatoes.
Affected fruit develop white, bleached areas on exposed areas usually the shoulders of the fruit , which become obvious during ripening Sunken areas with a paper-like surface later develop. Management- Maintaining healthy foliage is important in protecting developing fruit from sunscald. Caged tomatoes suffer less sunscald than staked tomatoes or those allowed to grow on the ground. Artificial shading may be beneficial where fruit exposure to direct sunlight is expected. ONION 1. Fields that are over-irrigated, allowed to dry completely and then over-irrigated again often have many split bulbs.
This condition is more prevalent in areas of the field were stands are thin or uneven. Secondary growth of the affected bulb often occurs as one to several small bulbs protruding from the split basal plate. Bulb mites Rhizoglyphus species are frequently associated with bulb splitting. However, they have yet to be implicated as the causal agent.
Management- Attention to seedbed preparation, planting and the use of high quality seed will result in uniform stands, which will reduce this disorder. The maintenance of uniform irrigation and fertilization practices to prevent phases of rapid and slow growth of onion bulbs can reduce the incidence of this disease.
Greening can occur if onion bulbs are exposed to sunlight during the growing season or the bulbs are allowed to cure for extended periods under moderate light. Sunlight causes the formation of chlorophyll in the outer scales, which results in the scales turning green. Management- An early fertilization program that promotes foliar development can reduce losses from greening at bulb maturity.
Avoid excessive and late season nitrogen application. Do not cure bulbs for extended periods in the field. This condition generally occurs on only a small percentage of the plants in a field. Leaf tissue is variegated resulting in tissues that have a normal green color being directly adjacent to tissues that are varying shades of yellow to white in color. Variegated tissue patterns may be mosaic or linear. OEDEMA— Oedema is a physiological response of the plant to excessive soil moisture during periods of cool nights and warm, humid days.
Many small scabby lesions form on the underside of the cabbage leaves. Oedema may be confused with thrips damage. Management- Avoid irrigation during times when day-night temperature variation is great. Younger leaves show signs of browning at the tips.
In cabbage, the browning can be seen only after the head is cut open. Management- Proper irrigation should be provided. Caused by damage to the terminal growing point due to low temperature, cutworm damage or rough handling.
Management- plants should take care during intercultural operations, planting should be in proper time. Rapid growth causes splitting of heads. Early maturing cultivars are most susceptible. Management- This disorder may be alleviated by avoiding over-watering and maintaining uniform growth with proper irrigation. Uneven watering practices too wet followed by too dry , low soil fertility and low soil pH are also possible stress factors.
Over mature or improperly stored cucurbits may also develop a mild bitterness, which is often not severe enough to prevent gardeners from eating them. The symptom, in mild cases, is a silvering parallel to the veins in the upper surface of leaves, but in severe cases silvering includes the entire upper leaf surface and the bleaching of stems, petioles, flowers and fruits. Leaf silvering was distinguished from silver mottling, a genetically controlled characteristic, by differences in distribution of silver over the leaf surface, the developmental reversibility of silvering and the bleaching effect of severe silvering on various plant parts.
Low soil moisture increased the severity of silvering. Fruit tissue separation, such as hollow heart in watermelon, may also be due to inadequate pollination and may be worsened by rapid fluctuation in environmental conditions affecting fruit development.
Causes of incomplete pollination may be inadequate pollen transfer by pollinating insects; inadequate pollen sources Pollenizers ; or hot, dry weather that reduces pollen viability or that desiccates flower parts during pollination. Hollow cavities in fruit and vacant seed cavities are related to lack of seed formation, again traced back to poor pollination.
Water soaked spots appear at the point of attachment of the senescent petals. This occurs due to sudden change in the rate of transpiration, especially in reduced moisture. Management- It can be controlled by supply light irrigation regularly, avoid heavy application of nitrogen fertilizers and adding lime to the soil or spray anhydrous calcium chloride. Management- Give light and frequent irrigation at flowering and fruit set stages. Spray the crop either NAA 50 ppm or Tricontanol 2 ppm at full bloom stage.
Rapid desiccation lead to sunken area usually had white or grey colour in green fruits. BROWNING- Appearance of water soaked lesions in the steam, leaf and on the surface of the curd which later become rusty and brown in color due to deficiency of boron.
Young cauliflower plants become chlorotic in nature and may turn white, particularly along the leaf margins, leaves also become cupped and wither. Management- Spraying the crop with 0. It is also referred as premature heading. The causes of buttoning are transplanting over-aged seedlings, poor nitrogen supply, and wrong selection of cultivars.
Due to higher or lower temperature than the optimum temperature required for a particular variety, temperature fluctuation at the time of curd development, poor seed stock generally causes ricyness. Management- Selection of proper variety and transplanting at right time controls this problem. The cultivation at improper season encourages this disorder. Management- Sowing of good quality seeds in right times under proper cultural practices minimizes the fuzziness.
It generally occurs due to due to deficiency of calcium and excess of K. Management- Balanced use of fertilizers. Increase Ca level in soil. Grow resistant varieties. It occurs due to genetic factors and other factors Higher dose of ammonical fertilizers, irregular irrigation. Management- Proper spacing, use of N fertilizers other than ammonical fertilizers.
Organic farming was the principal farming method before "modern agriculture". After two World Wars, chemicals that were used as weapons were converted into fertilizers and pesticides for "peaceful" use. Farmers came to adopt "modern" technology in order to lessen workload while the societal base shifted from agriculture to manufacturing and services. Consequently, organic farming became marginal and regarded as old-fashioned and laborious technique with low productivity.
The conventional agriculture after the green revolution depended on chemical compounds that had a negative impact on soil, human health and the environment. It relies on ecological processes, biodiversity and cycles adapted to local conditions, rather than the use of inputs with adverse effects. According to USDA, Organic agriculture is an ecological production management system that promotes and enhances biodiversity, biological cycles and soil biological activity.
It is based on minimal use of off-farm inputs and on management practices that restore, maintain and enhance ecological harmony. However, Northbourne published his manifesto of organic farming, Look to the Land, in which he coined the term "organic farming.
In this book he adopted Northbourne's terminology of "organic farming. Ensuring long-term, ecological, systems-based organic management. Confirming long-term, biological based soil fertility. Excluding certain unproven, unnatural and harmful technologies from the system. Avoiding pollution from surrounding environment. Maintaining organic integrity throughout the supply chain.
Providing organic identity in the supply chain. To produce food of high nutritional quality in sufficient quantity. To interact in a constructive and life enhancing way with all natural systems and cycles. Progressive Horticulture: Holistic Approaches for Production 29 To encourage and enhance biological cycles within the farming system, involving micro- organisms, soil flora and fauna, plants and animals. To maintain and increase long term fertility of soils. To use, as far as possible, renewable resources in locally organized agricultural systems.
To work, as far as possible, within a closed system with regard to organic matter and nutrient elements. This aims to reduce external inputs. To work, as far as possible, with materials and substances which can be reused or recycled, either on the farm or elsewhere. To give all livestock living conditions which will allow them to perform the basic aspects of their innate behaviour. To minimize all forms of pollution that may result from agricultural practices.
To maintain the genetic diversity of the agricultural system and its surroundings, including the protection of plant and wildlife habitats. To allow agricultural producers a living according to the UN human rights; to cover their basic needs and obtain an adequate return and satisfaction from their work, including a safe working environment.
To consider the wider social and ecological impact of the farming system. They are as follows. Artificial chemicals destroy soil micro-organisms resulting in poor soil structure and aeration and decreasing nutrient availability. Artificial fertilizers and herbicides are easily washed from the soil and pollute rivers, lakes and water courses. Artificial pesticides can stay in the soil for a long time and enter the food chain where they build up in the bodies of animals and humans, causing health problems.
Hence, to maintain soil health, abandon use of chemicals. Crops should be moved to a different area of land each year, and not returned to the original site for several years. Crop rotation means having times where the fertility of the soil is being built up and times where crops are grown which remove nutrients. Crop rotation also helps a variety of natural predators to survive on the farm by providing diverse habitats and sources of food for them.
Green vegetation is not normally used as it can take a long time to decompose and can attract pests and fungal diseases. Mulches have several effects on the soil which help to improve plant growth viz. Alternative mulching materials include black plastic sheeting or cardboard.
However these materials do not add nutrients to the soil or improve its structure. Progressive Horticulture: Holistic Approaches for Production 30 d. However, in many developing countries including India, the availability of organic manures is not sufficient for crop requirements; partly due to its extensive use of cattle dung in energy production.
Green manuring with Sesbania, cowpea, green gram etc are quiet effective to improve the organic matter content of soil. However, use of green manuring has declined in last few decades due to intensive cropping and socioeconomic reasons. Considering these constraints International Federation of Organic Agriculture Movement IFOAM and Codex Alimentarius have approved the use of some inorganic sources of plant nutrients like rock phosphate, basic slag, rock potash etc.
These substances can supply essential nutrients and may be from plant, animal, microbial or mineral origin and may undergo physical, enzymatic or microbial processes and their use does not result in unacceptable effects on produce and the environment including soil organisms. Following bacterial and fungal biofertilizers can be used as a component of organic farming in different crops.
It is a method of making compost with the use of earthworms that generally live in soil, eat biomass and excrete it in digested form. It is generally estimated that worms which is an ideal population for one sq. These are rich in macro and micronutrients, vitamins, growth hormones and immobilized microflora.
The average nutrient content of vermicompost is much higher than that of FYM. Application of vermicompost facilitates easy availability of essential plant nutrients to crops.

It helps to maintain environment health by reducing the level of pollution. It reduces human and animal health hazards by reducing the level of residues in the product.
It helps in keeping agricultural production at a sustainable level. It reduces the cost of agricultural production and also improves the soil health. It ensures optimum utilization of natural resources for short-term benefit and helps in conserving them for future generation. It not only saves energy for both animal and machine, but also reduces risk of crop failure.
It improves the soil physical properties such as granulation, good tilth, good aeration, easy root penetration and improves water-holding capacity and reduces erosion. Organic manure is not abundantly available and on plant nutrient basis it may be more expensive than chemical fertilizers if organic inputs are purchased.
Production in organic farming declines especially during first few years, so the farmer should be given premium prices for organic produce. The guidelines for organic production, processing, transportation and certification etc are beyond the understanding of ordinary Indian farmer. Marketing of organic produce is also not properly streamlined. Their produce either sells in the open market along with conventionally grown produce at the same price or sells purely on goodwill and trust as organic through select outlets and regular specialized markets.
These farmers may never opt for certification because of the costs involved as well as the extensive documentation that is required by certifiers. In India, about There was a growth of 0. In Madhya Pradesh, growth of There was a growth of In Maharashtra, growth of In Rajasthan, growth of In Odisha, growth of In Karnataka, growth of Note- Data values are in hectare.
As the conventional farming fails to provide sustainable food, it has also created many problems of soil and environmental health. The traditional and local knowledge systems enhance agricultural soil quality and biodiversity as well as nutrient, pest, and water management, and the capacity to respond to environmental stresses such as climate. The development of sustainable agriculture through organic farming will require significant structural changes, in addition to technological innovation, farmer-to-farmer networks, and farmer-to consumer solidarity.
The required change is impossible without social movements that create political will among decision-makers todismantle and transform the institutions and regulations that presently hold back sustainable agricultural development.

Musa, M. Thesesubstances are used mainly for the root initiation, e. Ethrel also useful for sex expression in cucurbitaceous vegetable crops. Eg, Ethephon, Ethrel. IBA enhances root formation on cuttings. Cytokinins also help in quick and profuse root formation on cutting and layers. By use of IBA, profuse root formation is observed in cutting at fig, pomegranate, croton, rose rootstock, hibiscus, grape etc. Many seeds have natural dormancy which can be overcome by dipping the seeds in auxins.
Air layering in Guava c. Grapes, Mangoes, Sapota. Different methods are used for the treatment of cuttings and layers with plant growth regulators. After the treatment, the cuttings are planted in the nursery or in other suitable growing medium. The concentration of the hormone or growth regulator usually varies from 20 ppm to ppm, depending on the plant species and type of the cuttings.
The concentration is usually low for easy rooting species and higher for difficult to root species. The nurserymen rarely use this method. However, it is very useful for difficult to root species, where some materials like vitamins, sugars and nitrogenous compounds are also used along with the growth regulators for facilitating rooting in such species.
It is very effective method of treating cuttings with growth regulating chemicals. It is followed by most of the plant propagators for raising plants through cuttings. In this method, the basal ends of cutting are dipped in the concentrated solutions of a hormone for a short time, usually for 5 seconds to 2 minutes. The treated cuttings are then planted in the nursery or field for rooting.
The concentration of hormone for quick dip method ranges between ppm and 10, ppm, depending on the species and type of the cuttings. Usually a concentration of 4, to 5, ppm is used for the purpose. Higher concentrations may cause injury to the cuttings and thus should be avoided. After treating the cuttings, extra powderadhering to the cuttings should be removed by shaking. Cuttings are immediatelyinserted in the rooting medium.
Seradix, a popular formulation is used by thenurserymen in this method. For effective rooting, the cut ends of the cuttings shouldbe moistened before the treatment. At the same time, the excess of powder should beremoved to avoid adverse effects on the rooting process.
Cuttings taken from such plants, root better as compared to untreated plants. Honeybee wax may also beused in place of Lanoline. After mixing, the mixture is kept open inair for few hours. The alcohol evaporates. The dried talc is then ground to fine powder. This fine powder should be kept in airtight container and can be used for treating cuttingsas and when required. It is then dissolved in a small quantity of acetone or alcohol. When the contents are fully dissolved, the final volume is made with distilled water.
The pH of the solution should be nearly neutral. If the pH of the solution is higher or lower, it may not induce rooting; rather it would affect the rooting process adversely. The pH of the solution can be adjusted with the help of 0. Citric acid, humic acid may also be used for lowering the pH of an alkaline solution.
Hormonal solution should preferably be prepared fresh to avoid the solution becoming inactive. The cans of solution, however, can be stored in a cool, dry and dark place. The required quantity of the lanolin greenish-yellow colored grease like substance is also weighed and heated slightly in a beaker under gentle flame. When, the lanolin slightly liquefies, the dissolved hormone is poured in it. The contents are mixed thoroughly with constant stirring with a glass rod.
The contents are then allowed to cool down. The paste is thus ready for use. Until use, the paste may be kept in a cool, dry and dry place. These are readily available in the market in various forms but it is always better to prepare them at nursery site it self.
The hormones not only induce rooting but also help in growth and development of the roots. Indole butyric acid IBA and Naphthalene acetic acid NAA are most effective incuttings and layers and these are used in tissue culture media also. Therefore, they must be stored in cool and dry places preferably in a refrigerator. If required to store for some time, use of refrigerator is desirable.

The simplest and oldest method for soilless culture is a vessel of water in which inorganic chemicals are dissolved to supply all of the nutrients that plants require U C Davis Today, it is used widely in research facilities as a technique for studying plant nutrition.
Various modifications of pure-solution culture have occurred. Gravel or sand is sometimes used in soilless systems to provide plant support, and retain some nutrients and water. Liebig and Knop and Sachs around initiated the systematic study of plant nutrition.
Liest published work on growing terrestrial plants without soil was the book, Sylva Sylvarum by Sir Francis Bacon, printed a year after his death. In , John Woodward published his water culture experiments with spearmint. He found that plants in less pure water sources grew better than plants in distilled water. In Gericke introduced the term hydroponics although he asserts that the term was suggested by Dr.
In Sachs and Knap first developed nutrient solution. In Dennis R. Hoagland and Daniel I. Arnon wrote a classic agricultural bulletin, The Water Culture Method for Growing Plants without Soil, debunking the exaggerated claims made about hydroponics. Hoagland and Arnon found that hydroponic crop yields were no better than crop yields with good quality soils Hoagland and arnon These two researchers developed several formulas for mineral nutrient solutions, known as Hoagland solution. Modified Hoagland solutions are still used today.
Hydroponics intended to take place on Mars are using LED lighting to grow in different color spectrum with much less heat Heiney A. In Nutrient solution was first developed by Sachs and Knap. In India hydroponics was first introduced at Kalimpong in Darjeeling W. In Cooper et al. In Jensen and Collins developed Aeroponics.
It should have a recycling ability so that the material can again be used after once being used. Technical specifications of substrates used in soil less growing media. The substrate used should be Inert no reaction with the nutrients , pH should be neutral, porous.
It should have Low density, hydrophilic, Should be Free from grit, heavy metals and radioactive pollutants. It should be applicable in natural form without need for processing. Should have the constant quality no decrease of physical properties during use and the material should be cheap and easily available.
Material should be having a life span of at least three years, Should be easy to use. Material should be resistant to sterilized several times without structural quality change and should be pest free Csaba, Solution culture Metohd of growing the vegetables without soil but using the mineral nutrient solutions in water solvents. The main crops grown under the solution culture are tomato, chillies and cucumber.
These are broadly divided into two parts a Circulating methods closed system : In this method the nutrient solution is pumped through plant root system and excess solution is collected and reused. It is further divided into two parts 1. Nutrient film technique NFT It is growing of plants bare rooted in long water proof channels which flows in a very shallow stream of recalculating water into which are dissolved all the minerals required to grow the healthy plants 2.
Deep flow technique DFT : It is the technique where the plants are planted in shallow beds and a nutrient solution is constantly flowed over and around the root zones of the plants. It is ideal for the plants which are without deep root systems and plant that have quick grow cycle. Benton et al. Root dipping technique: In this technique the Plants are grown in small pots filled with little growing medium. The pots are placed in such a way that lower 2 — 3 cm of the pots is submerged in the nutrient solution in which some roots hang in the air above the nutrient solution for aeration.
This technique does not require expensive items such as electricity, water pump, channels, etc. For root crops beet, raddish, etc. Floating technique: In this technique the plants are established in small pots are fixed to a Styrofoam sheet or any other light plate. They are allowed to float on the nutrient solution filled in the container and solution is artificially aerated 3. Capillary action technique: In this technique the planting pots of different sizes and shapes with holes at the bottom are used.
These pots are placed in shallow containers filled with the nutrient solution. Nutrient solution reaches inert medium by capillary action. Aeration is very important in this technique. Solid media culture Aggregate systems These can be open systems or closed systems. It includes Hanging bag technique In this technique About 1 m long cylinder shaped, white interior black UV treated, thick polythene bags, filled with sterilized coconut fibre are used.
These bags are sealed at the bottom end and tied to small PVC pipe at the top. These bags are suspended vertically from an overhead support above a nutrient solution-collecting channel. Progressive Horticulture: Holistic Approaches for Production 41 Therefore, this technique is also known as verti grow technique. Seedlings or other planting materials established in net pots are squeezed into holes on the sides of the hanging bags. The nutrient solution is pumped to top of each hanging bag through a micro sprinkler attached inside the hanging bags at the top.
This micro sprinkle evenly distributes the nutrient solution inside the hanging bag. Nutrient solution drips down wetting the coconut fibre and plant roots Excess solution gets collected in the channel below through holes made at the bottom of the hanging bags and flows back to the nutrient solution stock tank.
In protected structures, the hanging bags in the rows and amongst the rows must be spaced in such a way that adequate sunlight falls on the bags in the inner rows. About 20 lettuce plants can be established per bag.
This system is suitable for leafy vegetables, strawberry, and small flower plants. Black colour tubes will have to be used for nutrient solution delivery to prevent mould growth inside Grow bag technique- In this technique 1 These bags are about 6 cm in height and 18 cm wide. These bags are placed end to end horizontally in rows on the floor with walking space in between The bags may be placed in paired rows depending on the crop to grow.
Make small holes on the upper surface of the bags and squeeze seedlings or other planting materials established in net pots into the coir-dust. Make 02 small slits low on each side of the bags for drainage or leaching.
Fertigation with black capillary tube leading from main supply line to each plant is practiced. The nutrient solution and water may also be added manually to these bags. Depending on the stage of crop growth and the prevailing weather conditions, vary the amount of water applied. Cover the entire floor with white UV resistant polythene before placing the bags.
This reflects the sunlight to the plants. It also reduces the relative humidity in between plants and incidence of fungal diseases. Trench or trough technique- In this technique the plants are grown in narrow trenches in the ground or above ground troughs constructed with bricks or concrete blocks.
Both trenches and troughs are lined with waterproof material thick UV resistant polythene sheets in two layers to separate the growing media from rest of the ground. The width of the trench or trough can be decided depending on the ease of operation.
Wider trenches or troughs will permit two rows of plants. The depth varies depending on the plants to grow and a minimum of 30 cm may be necessary. In Pot technique growing media is filled in clay or plastic pots. Volume of the container and growing media depend on the crop growth requirements.
The volume ranges generally from 01 to 10 litres. Growing media, nutrient solution supply, providing support to plants, etc. The panels compose a sealed box to prevent light penetration to encourage root growth and prevent algae growth. The nutrient solution is sprayed in fine mist form to the roots. Misting is done for a few seconds every 2 - 3 minutes. This is sufficient to keep roots moist and nutrient solution aerated. The plants obtain nutrients and water from the solution film that adheres to the roots.
The aeroponic culture is usually practiced in protected structures and is suitable for low leafy vegetables like lettuce, spinach, etc. The principal advantage of this technique is the maximum utilization of space. In this technique twice as many plants may be accommodated per unit floor area as in other systems. Soffer 1 Root mist technique: In this technique A nutrient mist solution is sprayed every minutes onto the roots of the plants that hang from frame in a root chamber. This technique is good for plants having aerial roots.
It saves time as there is no need of making the beds, weeding, watering. As far as the health is concerned there are no soil borne disease or nematode damage is there. Off season production of vegetable is possible. The vegetable can be raised early, higher yield can also be obtained from soilless growing media.
Water wastage is reduced and no need for electricity and pumps in case of non circulating system of solution culture. Higher initial capital expenditure. High degree of management skills is necessary for solution preparation. Limited to high value crops of the area of cultivation. Energy inputs are necessary to run the system. Yields were found to decrease when temperature of the solution rises during warm periods. It is an alternative of soil fumigation and we need not to depend on farm land.
The production of vegetables is not dependent on the farm land. Production of vegetables can be increased many times if we grow that in soilless media. Csaba L. Growing medium in hydroculture.

Effect of dissolved oxygen concentration in aerohydroponic on the formation and growth and adventitious root. When it comes to Periwinkle plant description, it is a perennial evergreen erect herbaceous, much branched, annual or perennial herb plant or is a species of flowering plant which can grow up to 30 to cm height.
Periwinkle plant is native to Madagascar, occasionally found wild but mostly naturalized up to an altitude of m. On commercial basis it is cultivated in Malagasy, Israel, India and United States and its cultivation extended to remaining parts of the world as an ornamental and medicinal plant. The USA is a top user of this plant raw material. The leaves of this plant are oval to oblong in shape with 2. These plant flowers fragment and flowers are white to dark pinkish purple in terminal in color with a darker red center.
These plants have significance in Ayurveda as the extracts of its roots and shoots are being used against several diseases. HEALTH BENEFITS AND USES These are mostly uses in natural remedy for leukaemia stage 1, lowers the high blood pressure naturally, good for diabetics, natural remedy for kidney stones, a natural fever reducer, good for asthma, a natural treatment for anemia, helps in treatment of ulcers and boils, can be used a natural burn cure, helpful in treating sore throat, good for brain health, a natural remedy for tonsillitis, a natural treatment for diarrhea.
Vincristin sulphate arrest mitosis in metaphase and is very effective for the treatment of acute leukaemia in children and lyphocytic leukaemias. The alkaloid also causes relaxant and antispasmodic effect on smooth muscles of the intestine and uterus, and direct myocardiac and central nervous system depression. Purple Periwinkle Higher alkaloid content. Pink colour flowered — Rosea contains more of alkaloids 4. There is no specific climatic requirement is essential for its growth.
These plants can be grown up to an elevation of to meter above sea level. Well distributed rainfall of cm or more is good for its cultivation. Humid conditions in climate will encourage the growth. You can get excellent yields under irrigated conditions as well. The growth of this plant is better than the subtropical areas as lower temperatures in the winter season. Periwinkle plan can be grown on a wide range of soils. However, deep loamy or sandy loam soil with medium richness fertility is better for commercial cultivation of Periwinkle crop.
In these soils, the root development is better and it makes easy to collect at harvest time. Coastal land, Laterite soil is also good for Periwinkle plant cultivation. Ensure levelled and weed free field with fine tilth stage, and manured adequately with farmyard manure or compost prior to sowing. Groundnut cakes are also applied at some places.
Herbicides like 2, 4-D and Gramoxone are mixed in the soil while manuring to prevent infestation by weeds. Freshly harvested seeds should be used with a seed rate of 2. These broadcasted seeds can be covered lightly with topsoil.
In this method, seeds are broadcasted at the onset of monsoon rainy season during June to July month of Indian climatic conditions. The seeds germinate in about ten days and in days develop pairs of leaves. You can soak the seeds and mix them with sand ratio meaning for 1 kg of seed, 10 kg of sand or neem cake at the time of sowing for easy handling and uniform distribution as seeds are small. Seed germination starts after a week of sowing.
You can expect flowering stage after 45 days of sowing. The benefit of transplanting over direct seed sowing is seedling with good vigour can be selected from nursery beds by discarding low quality ones. In transplanting method of raising, it is done on nursery beds during March to April in rows with a spacing of 10 cm and is planted 1.
It is advised to transplant in the main field at evening times with a recommended spacing of 45 cm x 30 cm. In this method, half kg grams of seeds are required to cover the 1-hectare field. In this method, the total plant density would be around 75, per 1- hectare field.
In this method of propagation, selection of 12 cm to 15 cm length cuttings with 6 to 7 nodes are best for good percentage of rooting. Dead or weak plants should be replaced by healthy ones. In case of rainfed crops, 5 to 6 irrigations are sufficient for obtaining optimum yield.
Mulching with rice straw or cut grass is beneficial. At early flowering stage top cm portion of the plant are removed to promote vegetative growth and alkaloid content. The plants are drought resistant and do not require much water. Termites and soil-borne insect sometimes infest the growing seedlings. Adding BHC 0. You can carry out first weeding after 2 months of sowing and second weeding after 4 months of sowing. Mulching the field with material like rice straw or any other cut grass can help in controlling weeds, retaining water and preventing soil erosion.
This can be checked by selecting dieback resistant varieties. Periodical spraying of Diethane Z controls Die-back, bud rot and other fungal infections. You can also spray mancozeb at an interval of 12 to 15 days. Crop rotation is advised to check this.
A little-leaf disease due to Mycoplasm like organisms was observed. Spraying tetracycline hydrochloride ppm is beneficial. Leaves Harvesting, it can be done 6 months and 9 months after sowing. Root Harvest, the crop should be cut one year after sowing. Usually, the plants are cut 8 cm above the ground level. The harvested crop can be dried for leaves, stem and seeds. Roots are cut into cm length and dried. The produce can be stored under normal storage conditions for one or two years.
Seed Harvest, it can be collect from matured pods 60 to 75 days before harvesting starts. YIELD The yield of the crop depends on many factors such as soil type, other climatic conditions, irrigation method and variety. Generally, first harvesting should be done for leaves in six months, you go for second harvesting in 9 months. Finally, roots can be harvested after 12 months.
The total yield of plant material consisting of foliage, basal, stem and roots from an irrigated crop in peninsular India is 2. Rain fed crop yields 1. NOTE: It is always recommended to contact the department of horticulture for symptoms of diseases and pests and their preventive measures in Periwinkle plant cultivation. However, if you are planning to cultivate on large scale, you must establish a marketing channel for bulk sale. These factors determine the suitability of a crop for a particular location, cropping pattern, management practices, and levels of inputs needed.
A crop performs best and is least costly to produce if it is grown under the most favorable environmental conditions. To maximize the production of any crop, it is important to understand how these environmental factors affect plant growth and development. The growth and development of plants are dependent on abiotic physical and biotic biological factors.
Abiotic factors include the physical environmental conditions and biotic factors include plants, animals and microbes. To attain the highest potential yields, a crop must be grown in an environment that meets crops requirements. A crop can be grown with minimal adjustments if it is well matched with its climate or growing condition. Unfavorable environmental conditions can produce a stress on plants resulting in lower yields.
Climatic changes will influence the severity of environmental stress imposed on vegetable crops. Moreover, increasing temperatures, reduced irrigation water availability, flooding, and salinity will be major limiting factors in sustaining and increasing vegetable productivity.
Extreme climatic conditions will also negatively impact soil fertility and increase soil erosion. Exposure of plants to temperature extremes at the onset of the reproductive stage has a major impact on fruit or grain production across all species. One potential strategy to minimize environmental conditions impact is to select varieties which can grow better in harsh climatic conditions. Environmental-plant interaction is fundamental to growth and development which emphasize the dynamic nature of plant growth.
Efficient forms of growth and development in higher plants necessitates close coordination of anatomical form and physiological function, which is discernible at three distinct levels: in cellular and sub-cellular processes, within tissue systems and at whole plant level Carl et al.
Sowing is the beginning of the process, after which plants emerge, grow and develop with or without transplanting and may be harvested in vegetative in Cole, bulb, tuber, root, salad crops or reproductive phase Solanaceous fruits, peas, beans and cucurbits. If the crop is grown for reproductive organs, the vegetative phase is followed by flower bud differentiation, anthesis, fertilization, concentrated or continuous fruiting and ripening followed by new growth, dormancy or death of a plant.
These are primarily the manifestations of physiological processes supplemented by characteristics of production system. There are four prime environmental factors: Temperature, light, soil and water. Temperature is the main variable to take into account to understand plant performance. Optimum temperature range may be defined as the temperature range within which maximum photosynthesis and normal respiration takes place throughout the life cycle of the crop and thus highest marketable yield may be realized.
In some crops, low temperature range is ideal for high rate of photosynthesis and normal rate of respiration while in some other crops, relatively high temperature range is necessary. For example in case of tomatoathigher temperatures, trusses appear faster Adams et al.
