Field experiments were conducted during kharif and rabi for two consecutive years (2010-11 and 2011-12) to evaluate the direct and residual effect of various organic manures and crop residues alone and along with jeevamrut on productivity and economics of soybean – wheat cropping system. Three organic manures ( FYM, vermicompost and compost) alone and along with jeevamrut, three crop residues (cotton, wheat and soybean) @ 5 ton ha-1along with jeevamrut were applied/incorporated in soil one month before sowing to both soybean and wheat crop. Only nitrogen level was balanced through manures and no phosphorus and potash were applied, jeevamrut was applied @ 500 l ha -1at 30 and 45 DAS. The pooled results of two years revealed that significantly higher soybean grain equivalent yield (33.48 q ha -1), production efficiency of system (19.41 kg day -1ha -1) and maximum B:C ratio (2.21) were recorded with 100 % RDN through vermicompost + jeevamrut (T6) followed by 100 % RDN through vermicompost (T3).
