Effect of growth stimulator on the yield of hybrid rice varieties in Boro season
Abstract
Rice (Oryza sativa L.) is one of the main cereal crops and commonly grown all over the world for multiple purposes. The present investigation was undertaken for the improvement of yield of rice varieties through the manipulation of filled-grain percentage by plant growth stimulator. This experiment was comprised of two factors; Factor A: Rice varieties: BRRI hybrid dhan3 and BRRI dhan29, Factor B: PGS and fertilizer management: Recommended fertilizer dose (T1), Recommended fertilizer dose + Akota + Global (T2), Recommended fertilizer dose + Akota + Global + Calsol (T3), Recommended fertilizer dose + Akota + Global + Magic Growth (T4), Recommended fertilizer dose + Akota + Global + Calsol + Magic Growth (T5). In case of variety the highest filled grains panicle-1 (180.36) and grain yield (7.09 t ha-1) was recorded from BRRI hybrid dhan3. In case of PGS and fertilizer treatment, the highest filled grains panicle-1 (168.7) and grain yield (6.99 t ha-1) were recorded from T3 (Recommended fertilizer dose + Akota + Global + Calsol). Due to the interaction the highest filled grains panicle-1 (197.7) and grain yield (7.78 t ha-1) were recorded from BRRI hybrid dhan3 × T3 (Recommended fertilizer dose + Akota + Global + Calsol). So, BRRI hybrid dhan3 and T3 (Recommended fertilizer dose + Akota + Global + Calsol) combinedly had outstanding superiority for yield over the other treatments.
