Abstract
Field studies were carried out to evaluate various green manuring crops viz. sesbania, guara and sunnhemp and grain legumes viz. mungbean and cowpeas for their biomass production and N contribution to soil. Plant sampling was done at 30, 45 and 60 days after sowing. Maximum, plant height and fresh shoot and root biomass were produced by sunnhemp at all the three growth periods but the grain yield and total biomass production at harvest stage (60 DAS) were maximum in case of Pakistani Janter (Sesbania aculeata), The yield of the follow-up wheat crop was also affected significantly by the residual effect of green manures and grain legumes and the maximum wheat grain and straw were recorded from the plots where Pakistani Janter was planted.
