| Abstract/Description: | Field experiments were conducted with cotton+soybean (1:1) inkharif 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 994to 1419 kg ha-1 with mean of 1193 kg ha-1 and variation of 9.8%; while RWUEranged from 1.21 to 1.69 kg ha-1 mm-1 with mean of 1.43 kg ha-1 mm-1 and variationof 9.2% over years. Conventional tillage (CT) and reduced tillage (RT ) with 100% recommended RDF gave significantly higher CEYand RWUE compared to othertreatments. CT+ FYM@5 t ha-1, CT+ 50% RDF + Vermicompost @1.5 t ha-1 andRT +50% RDF+VC @1.5 t ha-1 gave lower bulk density; while CT+FYM@5 t ha-1and CT+50% RDF+FYM @2.5 t ha-1 gave higher infiltration. Runoff and soil loss were significantly lower under CT+FYM @ 5 t ha-1 and CT+VC @ 3 t ha-1 . CT+50% N+FYM @ 2.5 t ha-1 and CT+100% N gave maximum gross returns,while CT+100% RDF and RT +100% Ngave maximum net returns. RT1 +FYM @5 t ha-1 , RT +50% RDF+FYM @2.5 t ha-1 and RT +100% RDF were superior formaximum 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. |
