The field experiment was conducted to study the effects of nitrogen fertilization reduction and organic and inorganic fertilizer application on rice yield, nutrient utilization efficiency and nutrient runoff loss. The results showed that: nitrogen application can significantly increase the effective panicle number per unit, Number of grains per panicle, plant height and stem length, but had no effect on 1000 grain weight and seed setting rate of the early rice. Compared with the conventional fertilization treatment, the rice yield of nitrogen fertilizer reduction treatment was slightly decreas...
