Vegetable Cultivation

Vegetable cultivation is a highly practised agricultural activity in India.Commercial horticulture includes the cultivation of both indigenous and exotic vegetables. Vegetable cultivation under the drip irrigation system provides favourable environment for crops growth to achieve higher yield and good quality produce. Adaption of improved irrigation method and supply of precision amount of irrigation water and nutrients to crops are the important in achieving greater yield and avoiding loss of water and nutrients. Micro irrigation can be used to irrigate vegetable crops efficiently in the greenhouse and open field conditions. Both the pan evaporation and FAO-56 Penman-Monteith methods have been adopted to estimate the water requirement of crops under greenhouse structures and in an open field condition. The fertilizer application along with micro irrigation system optimizes the water and fertilizer use efficiency. Vegetables require precision amount of irrigation and fertilizers application and suitable climatic conditions. A very limited information is available on the supply and management of these important inputs.This report presents the role of micro irrigation forthe cultivation of vegetable crops. The design and installation of micro irrigation system, estimation of irrigation requirement of various vegetable crops using micro irrigation are also presented in this manuscript of the report.

The article proposes a scheme of drip irrigation for growing vegetables in the backyard. In the conditions of change of climatic conditions, the question of lack of moisture sharply arises. For growing vegetables in areas of risky agriculture, irrigation is an important condition for obtaining high yields. In order to increase the technological efficiency of growing vegetables at the department of general agriculture of the Central Ukrainian National Technical University developed a prototype of a drip irrigation system for vegetables. A series of studies was conducted to provide moisture to the site and preserve soil air exchange. With the use of conventional irrigation, possible negative consequences in the form of soil flooding, the root system of plants is not able to develop evenly and is deficient in oxygen. The calculation and the scheme of drip irrigation of tape type are offered. In the proposed design for drip irrigation of the area under vegetable crops used a container with water to provide a small constant water pressure in the strips. This made it possible to water as needed, as well as to use a solution tank to feed the plants, protect them from stress, improve development and increase yields. The use of drip splicing allowed the first fruits to appear a decade earlier and increase yields by 25-50%. The use of drip tape irrigation system on the experimental plots allowed to increase the quantity and quality of tomato harvest. Also, the use of drip irrigation allowed to maintain the optimal water-physical regime in the root layer of the soil, which created the conditions for a better harvest. Thus, with the change of climatic situation, most of the Kirovohrad region was looking for in the zone of risky agriculture. Drip irrigation has an almost universal application, is effective in intensive technologies for growing crops and ornamental crops, as well as in garden areas, when the condition of the plant largely depends on the accuracy of maintaining the humidity and nutrition of plants.

The field experiment was conducted at Precision Farming Development Centre, Central Institute of Agricultural Engineering, Bhopal on influence of different irrigation methods in three continuous years (2010-2013) on the performance pea crop. Conventional flood irrigation, micro sprinkler and drip irrigation systems were adopted as three treatments and with seven replications in each treatment in the study. Pea (Arkel variety) crop was sown at a spacing of 45 X 10 cm. During the period of experiment flood irrigation were applied on weekly basis and micro irrigation and drip irrigation systems were operated every third day to meet the crop water requirement. The total quantity of water applied in flood, drip irrigation and micro sprinkler systems were 387.5, 244.7 and 273.5 mm respectively. Maximum crop yield was observed under micro sprinkler system (98.60 q/ha) followed by drip and conventional irrigation system. Saving of water was found better under drip irrigation over micro sprinkler irrigation system.

Traditional vegetables in Tanzania have been underutilized by farmers and neglected by research and development programmes. In the framework of the project ‘Promotion of Neglected Indigenous Vegetable Crops for Nutritional Health in Eastern and Southern Africa’ led by the World Vegetable Center (AVRDC) and partners, focus group meetings were conducted in 10–12 villages in each of four districts of north-east Tanzania, which differed in ethnicity as well as in altitude, climate and soil conditions. Farmers named 10–34 different traditional vegetables per village, summing up to an overall of 102 in all four districts, about half of which were only identified by local names. The number of wild traditional vegetables used was always greater than the number of cultivated traditional types, with ratios of wild to cultivated vegetables ranging from 11:9 in an urban highland district to 59:11 in a rural coastal district. Some wild traditional vegetables were found to be threatened with genetic erosion due to changes in land use and eating habits. The degree of urbanization and the availability of infrastructure contributed more strongly to genetic erosion as compared to climatic conditions. Farmers' training encouraged exotic vegetable cultivation and reduced traditional vegetable diversity. At the same time, indigenous knowledge on how and where to collect, cultivate and prepare traditional vegetables was disappearing.

Two different irrigation systems, subsurface drip irrigation and furrow irrigation, are tested to investigate the level of viral contamination and survival when tertiary effluent is used in arid and semi-arid regions. The effluent was injected with bacteriophages of PRD1 and MS2. A greater number of PRD1 and MS2 were recovered from the lettuce in the subsurface drip-irrigated plots as compared to those in the furrow-irrigated plots. Shallow drip tape installation and preferential water paths through cracks on the soil surface appeared to be the main causes of high viral contamination in subsurface drip irrigation plots, which led to the direct contact of the lettuce stems with the irrigation water which penetrated the soil surface. The water use efficiency of the subsurface drip irrigation system was higher than that of the furrow irrigation system. Thus, subsurface drip irrigation is an efficient irrigation method for vegetable crops in arid and semi-arid regions if viral contamination can be reduced. Deeper installation of drip tapes, frequent irrigations, and timely harvests based on cumulative heat units may further reduce health risks by ensuring viral die-off under various field conditions.

Worldwide pressurized micro irrigation technologies have remarkably shown its effectiveness in water saving and increasing the crop yield with several other benefits. Although among the small land holder farmers, adoption of pressurized micro irrigation system is minimal mainly due to the small land holding and more system cost. Gravity micro irrigation is one of the best alternatives for the small land holder farmers with almost all benefits derived by the pressurized micro irrigation. Gravity fed drip irrigation has enormous capability for water and nutrient conservation. This review paper explains design, layout, features of gravity fed micro irrigation system, its suitability and benefits to the small farmers for achieving more yield per drop of water. The comprehensive attempt in the current review analysis is to enhance a most favourable methodology and technology to magnify and intensify the operation of gravity fed drip irrigation system in extensive cultivation and production. Further to accomplish the efficient utilization of available water resources for growing horticultural crops in hilly region of India, gravity-fed micro irrigation should be integrated with water harvesting system.

A study was conducted to determine the feasibility of fieldscale CO2 enrichment of vegetable crops grown under tunnel culture. Cucumber, squash and tomato were grown under polyethylene tunnels in a manner similar to commercial practices in southern California. The buried drip irrigation system was used to uniformly deliver an enriched CO2 air stream independent of irrigation. CO2 concentration in the tunnel atmosphere was maintained between 700-1000 ppm during daylight hours. Enrichment began two weeks after planting and continued for four weeks. At the end of the treatment phase, enrichment had significantly increased plant dry weights. This growth advantage continued through harvest, with enriched plots yielding 20%, 30% and 32% more fruit of squash, cucumber and tomato, respectively. As performed in this study, the expense of CO2 enrichment represented less than a 10% increase in total pre-harvest costs. Industrial bottled CO2 was used in this study; since bottled CO2 is captured as a byproduct of industrial processes, this usage represents a recycling of CO2 that would otherwise be vented directly to the atmosphere.

The oregano is a plant, rich in essential oil and very used as spice in the preparation of foods. The objective of this paper was to analyze the viability of irrigation for oregano in Presidente Prudente, São Paulo state, Brazil, including economic risk factors, their effect on irrigation total cost, as well as the different pumping kinds. The Monte Carlo simulation was utilized to study the economic factors: fixed cost, labor, maintenance, pumping and water. The use of irrigation for the oregano in the region of Presidente Prudente is indicated because of its economic feasibility and the reduced risks. The average values of the benefit/cost for all water depths tested were higher than 1, indicating viability. The use of irrigation promoted lower risks compared to the non irrigated crop. The micro irrigation system presented greater sensitivity to changes of prices of the equipment associated to the variation of the useful life of the system. The oregano selling price was the most important factor involved in annual net profit. The water cost was the factor of lesser influence on the total cost. Due to the characteristic of high drip irrigation frequency there was no difference between the tariffs based in use hour of electric energy classified as green and blue, which are characterized by applying different rates on the energy consumption and demand according to the hours of day and times of the year. For the studied region it was recommended drip irrigation water management of oregano with the daily application of 100% of pan evaporation Class A using electric motor with tariffs blue or green.

This work aimed to analyze the economic feasibility of the irrigation system by dripping and nitrogen fertilization in jambu production. The experiment was conducted at the Experimental Farm of Igarapé-Açu, a site owned by UFRA, in protected cultivation, from May to July in 2016. The treatments consisted in four soil water tensions (12, 18, 24 and 30 kPa) and four nitrogen doses (0, 50, 100 and 150 kg ha-1). The economic analysis of the jambu irrigated production was sustained by the theory of producing costs considering both depreciation cost and alternative cost. The treatment with the highest profit was managed at 18 kPa with a nitrogen dose of 50 kg ha-1, with a profit of R$ 1,548.54 for an area of 1,000 m.². The drip irrigation and nitrogen fertilization were economically viable for the jambu crop.
