In Bihar rice is a major food crop and has more than 5.14 M ha area. Recent years environmental stress becoming major threats to rice cultivation and adversely affecting the productivity of crop. Drought resistance varieties and some microbes have proved their potential in mitigation of stresses and enhancing the rice yield under stress condition. In this study, two Trichoderma isolates were tested with three drought tolerant varieties i.e. Sahbaghi dhan, DRR44 and Neelam. The interaction effect between variety and treatment was significant. Trichoderma treated seed enhanced both growth and yield attributes in rice compared to untreated. Variety i.e. Sahbhjagi dhan + (T1) Trichoderma isolate 1 gave maximum grain (42.50 q/ha), followed by Sahbhagi dhan + (T2) Trichoderma isolate 2 (41.84 q/ha) and then DRR44 + (T1) Trichoderma isolate 1 (39.60 q/ha), DRR44 + (T2) Trichoderma isolate 2 (38.93 q/ha) under stress condition. The minimum grain yield (30.20 q/ha) was obtained from drought susceptible variety i.e. IR 64 under stress without seed treatment with Trichoderma. The results of this present work could be advised in drought prone area to alleviate stresses under field condition.
