High Ratoon Season Rice Yield is Achieved Through Optimized Variety, Nitrogen Management and Temperature-Solar Radiation Resources.

ABSTRACT: Ratoon rice (RR), recognized as an efficient method of rice cultivation, plays a crucial role in the food production system. By enabling two harvests-during the main season rice (MSR) and the ratoon season rice (RSR)-from a single planting, this cropping system significantly enhances the utilization of land and temperature-solar radiation resources, thereby providing essential support for food security. However, the yield formation of RSR is constrained by several factors, including the adaptability of the rice variety, nitrogen fertilizer management strategies, and the uneven distribution of temperature and solar radiation resources, which collectively hinder the actual realization of its yield potential. This research first employed a meta-analysis approach to identify the optimal nitrog
