Construction of dominant rice population under dry cultivation by seeding rate and nitrogen rate interaction

Abstract This study used the rice cultivar Suijing 18 to investigate the effects of morphological characteristics, photosynthetic changes, yield, as well as nitrogen absorption and utilization. The interaction between seeding rate and nitrogen rate was also assessed to identify the most suitable val...
