Field experiments were conducted with cotton+soybean (1:1) in seasons of 2005, 2007, 2009 rotated with soybean+pigeonpea (4:2) in 2006 and 2008 to identify an efficient tillage and nutrient management practice in a semi-arid Vertisol at Parbhani. The study was conducted in split-plot design with 3 tillage and 5 fertilizer N treatments. The cotton equivalent yield (CEY) ranged from 994 to 1419 kg ha with mean of 1193 kg ha and variation of 9.8%; while RWUE ranged from 1.21 to 1.69 kg ha mm with mean of 1.43 kg ha mm and variation of 9.2% over years. Conventional tillage (CT) and reduced tillage (RT ) with 100% recommended RDF gave significantly higher CEYand RWUE compared to other treatments. CT+FYM@5 t ha , CT+ 50% RDF +Vermicompost@1.5 t ha and RT +50% RDF+VC@1.5 t ha gave lower bulk density;while CT+FYM@5 t ha and CT+50% RDF+FYM@2.5 t ha gave higher infiltration. Runoff and soil loss were significantly lower under CT+FYM @ 5 t ha and CT+VC @ 3 t ha . CT+50% N+FYM @ 2.5 t ha and CT+100% N gave maximum gross returns, while CT+100% RDF and RT +100%Ngave maximum net returns. RT +FYM@ 5 t ha , RT +50% RDF+FYM@2.5 t ha and RT +100% RDF were superior for maximum BC ratio. Based on a regression model of CEY through rainy days and crop seasonal rainfall, CT+100% RDF and RT +100% RDF were superior with maximum sustainability yield index over years. Not Available |
