Influence of Different Water Regimes and Nutrient Management Practice for Rice Production

Field experiments were conducted in the Eastern farm of Pandit Jawaharlal Nehru College of Agriculture and Research Institute, Karaikal, during Kharif season of 2008-2009 with an objective to assess the effect of different water regimes and nutrient management practices on yield, yield attributes and uptake of nutrients. Among the different rice eco systems, crop grown under saturated water condition had recorded the highest grain, straw yield and panicle weight whereas rice transplanted under continuous submergence condition had recorded the highest N uptake but rice transplanted under saturated water regimes had recorded highest phosphorus and K uptake. The rice sown under aerobic conditizon under dry ploughed soil had recorded the lowest grain and straw yield. The higher grain yield was recorded by application NPK @ 120:60:40 kg ha^-1 and lowest yields were reported by absolute control.
