Effect of tillage practices and nutrient levels on economic, uptake and available nutrient in soybean based cropping systems

Abstract

The field investigation was undertaken during kharif and rabi season of 2014-15 and 2015-16 on clayey soil at the farm of AICRP on Integrated Farming Systems, VNMKV, Parbhani. Treatment consists of twelve treatment combinations comprising two tillage practices (minimum tillage, conventional tillage) and two cropping systems (soybean-rabi sorghum,soybean-wheat) in main plot, three levels of nutrients (75, 100 and 125 per cent RDF) in sub plot for soybean in kharif and after that for rabi sorghum and wheat in rabi season were assigned in a split-split plot design. The gross and net monetary returns, B:C ratio and economic efficiency were also found to be higher with practice of conventional tillage and 125 per cent RDF to soybean, rabi sorghum and wheat. Soybean-wheat cropping systems noted higher gross and net monetary returns, B:C ratio and economic efficiency. Also the nutrient uptake by crops was significantly higher in conventional tillage and application 125 per cent RDF treatments. Available nutrient status of the soil after harvest of crop was significantly higher in minimum tillage treatments.
