1992

Higher grain sterility was observed in Aus than in Boro rice. Late planted T. aman rice had more sterile grains due to low temperature at the reproductive stage associated with incomplete panicle emergence. Early planted Boro rice also suffered from low temperature at the reproductive stage resulting high grain sterility. In 1990 Boro field observations revealed very high grain sterility (40-90%) due to unusual fall of temperature in March resulting crop failure in several regions of Bangladesh.
