Effects of seeding time on grain yield,yield components and growth duration in different rice varieties

Abstract

Abstract: In this experiment,the effects of seeding time on the yield,yield components and growth duration in different rice varieties were studied.The results indicated that the grain yield declined with the delaying of rice seeding time,mainly caused by decrease of ripened grains per panicle.In addition,the reduce of 1000-grain weight and ripened panicles also contribute to the yield decrease.For the need that have to delay rice seeding time,some corresponding countermeasures were provided.

Key words: Prevention and control of disease, Vc fermentation waste residue, Protective ground, Tomato
