Review on the Effect of Irrigation Interval on Different Crop Production

In this review, the effect of irrigation intervals on growth and yield of onion, maize yield, growth characteristics for Chile pepper, vegetative growth and yield, growth analysis of soybean, forage production, growth and development of tomato, the effect of irrigation level and irrigation frequency on the growth of mini Chinese cabbage and Influence of irrigation interval, nitrogen level and crop geometry on production lettuce have been reviewed. The best performance irrigation interval for onion, maize, pepper, okra, soybean, forage, tomato, cabbage and lettuce are 5, 6, 1, 12, 8, 20, 1, 4 and 2 day respectively. Crop type, crop growth stage soil type, climate condition (temperature, rainfall, humidity, sunshine hour and wend speed) duration of the environment should be properly addressed and potential evapotranspiration and reference evapotranspiration should be estimated for determining of irrigating interval. In these cases, some of the studies are properly addressed these important parameters but some of the study not indicates. On the other hand chemical composition of water and soil, fertilizer application, method of research design and plant geometry are should be identified to eradicate the misjudgment of your best productivity of irrigation interval.
