ABSTRACT

A field experiment was conducted on rice at farmer’s fields to compare the performance of SRI with different N sources. The experiment was conducted in sandy loam soil during rabi 2013-14 with various N sources viz., Urea and Ammonium sulphate and the SRI was compared with various system of rice cultivation viz., conventional method and farmer’s own method. The results emanated from the experiment showed that the N application through Ammonium sulphate at 100 % recommended level under SRI, recorded the highest yield attributes of rice viz., number of tillers and productive tillers, number of grains per panicle, 1000 grain weight, total DMP, grain and straw yield. The yield was increased to the tune of 33.4%, 66.0 % over conventional and farmers method respectively.Water productivity was higher under SRI (0.94) overconventional (0.37) and farmer’spractice (0.18).Besides, SRI resulted in 40.5 %and 42.0 % water saving over conventional and farmers practice respectively.In addition, SRI recorded an increased net return of 49.0 % and 74.7% over conventional and farmer’s practice respectively.Harvest index was found to be higher under SRI (39.0 %), followed by conventional (35.0 %) and farmer’s practice (30.3 %).
