Nutrient management in soybean (Glycine max)-mustard (Brassica juncea) crop sequence

An experiment was conducted at Morena during 1993-94 and 1994-95 to study t he effect of organic and inorganic sources of plant nutrients on productivi ty, nutrient uptake and economics of soybean [Glycine max (L.) Merr.]-musta rd [Brassica juncea (L.) Czernj & Cosson] cropping sequence. Significantly higher seed yield of soybean was recorded with N-40 (1/2 B + 1/2 T) P80K20 (20 kg N applied as basal and rest 20 kg N top dressed at 30 DAS), whereas in mustard the yield was highest when N-40 (1/2 + 1/2) P80K20 (20 kg N supp lied through FYM and remaining 20 kg N through urea) was applied in soybean . The maximum mean total land productivity and net return were obtained fro m N-40 (1/2 + 1/2) P80K20. The uptake of NPK was maximum when soybean was f ertilized with N-40 (1/2 + 1/2) P80K20, whereas in mustard maximum uptake o f NPK was recorded with N-40 (1/2 + 1/2) P80K20, was given to soybean crop in kharif.
