| Experiment Background | Irrigation is generally needed to improve agricultural productivity to cope up with ever increasing demand for food to feed the expanding population. In India, Irrigation water accounts for 84% of the total water withdrawals. The target of producing 350 million tons of food grains by 2025 would be possible only through greater increase in the productivity of water, producing more from the given quantity of water. New irrigation strategies include deficit irrigation methods, which increase water use efficiency and crop productivity. Partial Rootzone Drying (PRD), an extension of deficit irrigation, is a new irrigation technique where about half of the root zone is irrigated, while the remaining root zone is allowed to remain dry. The wetting treatment is then reversed, allowing the previously well-watered side of the root system to dry down, while fully irrigating the previously dry side. This technique has the potential to reduce water demand of field-crops and fruittrees significantly as well as also increase canopy vigour and maintain yields at par with normal irrigation methods. This technique of PRD may help to save up to 50% of irrigation water without compensating yield. Proposed investigation, aims to test the feasibility of adopting the PRD to local conditions with the following objectives. | ||||||||||||||||||||
