Abstract

Efforts were made to unzip the influence of Azotobacter chroococcum on character association and effects of dependent traits on independent variables on seed yield. Significant positive association of seed yield per plant was noted with number of panicles per plant, number of filled grains per panicle, 1000-seed weight, husked grain length and amylose content in both Azotobacter inoculated and control situations. Fresh weight of shoots per plant at 45 DAT (days after transplanting) showed maximum direct contribution followed by root length towards seed yield per plant in uninoculated condition, but 1000 seed weight exhibited highest contribution followed by number of panicles per plant under inoculated condition. Wide variation was observed for characters association and path coefficient analysis under inoculated and uninoculated conditions.
