Impact of incorporating wheat straw together with basal nitrogen ratio on panicle formation and grain yield in rice.

ABSTRACT: Increasing spikelets differentiation, reducing their degradation and promoting big panicle formation are crucial approaches to increasing grain yield in rice. Straw incorporation and nitrogen (N) application have vital effects on rice yield, but the influence of incorporating wheat straw with N fertilizer ratio on spikelet differentiation, degeneration, and grain yield in rice is not clear. In this experiment, hybrid rice Fengyouxiangzhan (FY) and Yongyou 2640 (YY) were used as materials. Under the condition of total nitrogen application rate of 270 kg ha^- 2, the effects of local farmers' fertilizer practice (FP, basal fertilizer: tillering fertilizer: panicle fertilizer = 5: 1: 4) and improving basal fertilizer proportion (IP, basal fertilizer: tillering fertilizer: panicle fer
