Opportunities during 22-24, December 2022 at ICAR-CRIDA, Hyderabad
the lowest number of ear heads was found in combined application of D18 compost +
Trichoderma + NPK. Again, that maximum number of grains/ear head was recorded with
combined application of NPK + FYM, but remained at par with all other treatment except D 18
compost + Trichoderma + NPK and NPK. Different treatments registered non- significant
effects on test weight of rainfed wheat. The highest grain yield (19.33 q/ha) was obtained with
combined application of NPK and FYM and remained significantly superior to D18 compost
+Trichoderma + NPK and NPK. The highest straw yield (36.89 q/ha) was obtained in
combined application of NPK + FYM, but it remained at par with D 18 Compost + NPK and D 18
Compost + hydrogel + NPK. Even though no significant difference was observed in the harvest
index due to different treatments, FYM +Hydrogel + NPK registered the highest harvest index.

Conclusion
Since combined application FYM and NPK was found to be more effective, it can be accepted
to be more logical for adaption for water conservation in rainfed wheat. Being organic in nature,
it promotes environmental sustainability also.

Sorghum (Sorghum bicolor (L.) Moench) is mainly grown as a dual-purpose rainfed crop.
During times of fodder scarcity, sorghum stover is of great consolation. However, eroded
