Rapeseed (Brassica napus L.) shows a relatively obvious response to changes in water and nutrients. If the water is not applied appropriately or the fertilization is not reasonable, it can easily affect the yield. This study mainly collated and analyzed the performance of rapeseed in terms of yield formation, water use efficiency, and yield stability under different irrigation amounts, limited irrigation methods, and rainwater harvesting cultivation conditions. At the same time, the combined application effects of nitrogen, phosphorus, potassium fertilizers, and organic fertilizers under different water supply conditions were summarized, and the impacts on the growth of rapeseed, yield composition, nutrient absorption, and nitrogen utilization efficiency were analyzed in detail. Under moderate water shortage conditions, the use of multiple fertilizers in combination is more conducive to increasing yield and maintaining yield stability. From the perspective of coordinated regulation of water and nutrients, this research provides a reference basis for rapeseed to achieve high yield, high efficiency, and green production.
