Summary
Field experiments were conducted (2001-2006) to study the effect of agronomic management practices on biological nitrogen fixation in the extra-short-duration mungbean variety SML 668 in summer and kharifseasons in Punjab, India.Seed inoculation with Rhizobium recorded increase in yield by 12-16%. Conjunctive use of Rhizobium with phosphate solubilizing bacteria (PSB) and plant growth promoting rhizobacteria (PGPR) revealed synergistic effect on symbiotic parameters and grain yield of mungbean. Genotypes, VC 3890A, VC 6368, VC 6369\-30-65, VC 6173-10 and VC 6090A showed higher nodulation and leghaemoglobin content than check SML 668. Their nodulation pattern was in clusters and mainly on the tap toot. The time of sowing showed remarkable variation in size and shape of nodules and leghaemoglobin content. Data recorded from tillage versus no-tillage experiment revealed more nodulation and leghaemoglobin content in no-tillage treatment.
