Effect of seed inoculation and FYM on biological N fixation in soybean and nitrogen balance under soybean-wheat system on vertisol

Abstract: A field study was conducted during 1993-94 and 1994-95 on Typic Haplustert to study the influence of rhizobium inoculation, incorporation of FYM and fertilizer N on nodule number and weight, nitrogen fixation in soybean and N balance under soybean-wheat system. The inoculation of rhizobium to seed and incorporation of FYM one week before sowing of soybean increased the seed yield of soybean and grain yield of subsequent wheat. Similarly, inoculation of seed enhanced N fixation and incorporation of FYM left a net positive balance of 40 and 80 kg N, respectively. Though application of excess nitrogen also showed a net positive N balance, it reduced N fixation in soybean. A higher accumulation rate of available N at the all growth stages of soybean was noted with the incorporation of FYM and inoculation of seed over control.
