Abstract:

A field experiment was conducted during rabi, 2015-16 at farmer’s field located at K.C. peta village of Tirupati rural mandal of Chittoor district of Andhra Pradesh for optimizing the nutrient requirement of machine transplanted rice under mechanized system of rice intensification (MSRI) in Randomized Block Design with factorial concept with four nitrogen levels (80, 120, 160 and 200 kg N ha-1) and three phosphorus levels (40, 60 and 80 kg P2O5 ha-1) replicated thrice. Application of 160 kg N ha-1 and 200 kg N ha-1 recorded statistically at par grain, straw yield and returns. Hence, application of nitrogen @ 160 kg ha-1 was found to be optimum dose for machine transplanted rice. Levels of phosphorus and their interaction with nitrogen have no significant influence on grain, straw yields and returns due to initial soil phosphorus buildup of experimental site. Hence, application of 160 kg N ha-1 coupled with 40 kg P2O5 ha-1 can be recommended for machine transplanted rice for realizing higher yields and returns under mechanized system of rice intensification (MSRI).


Keywords: Nitrogen, Phosphorus, Grain yield, Straw yield and Economics.
