Abstract：The present study assessed the effects of nitrogen fertilizer application rate and management strategy on tiller development and yield components of mechanically transplanted rice in a paddy field with barley straw fully incorporated into the soil and prepared under the dried condition.Rice tillers developed steadily and grain was reasonable in the treatment with nitrogen fertilizers applied at 21kg/667m2 and the following management strategy:the proportions of N-fertilization at basal,tillering,and panicle stages were 40%,20%, and40%,respectively.Consequently,this treatment resulted in a high plot yield.Thus,the present study provides a scientific reference for rice production in the field with barley straw fully incorporated into soil.
