This article analyzes the effects of different water and fertilizer management regimes on the growth characteristics and yield performance of ‘Taishuu’ sweet persimmon, analyzes its water and nutrient requirements at different developmental stages, and focuses on the regulatory effects of irrigation levels, fertilization intensity, and water–fertilizer coupling on vegetative growth, leaf photosynthetic physiology, dry matter allocation, fruit enlargement, and yield components. Available evidence indicates that appropriate irrigation promoted shoot and canopy growth and supported fruit enlargement, whereas the yield-increasing effect of excessive irrigation gradually diminished. Moderate deficit irrigation at specific developmental stages could reduce fruit drop and improve water-use efficiency, but might decrease individual fruit weight. Fertilization similarly showed a pronounced nonlinear effect on tree growth and yield. Moderate and balanced nutrient supply was beneficial for maintaining leaf nutritional status and supporting fruit development, whereas excessive fertilization could induce excessive shoot growth, nutrient imbalance, and deterioration in fruit quality. Compared with conventional high-water and high-fertilizer management, water- and fertilizer-saving practices and precision integrated fertigation were more effective in coordinating vegetative and reproductive growth and improving water–fertilizer use efficiency and marketable yield. Future research should consider the phenological stage, tree age, crop load, soil conditions, and climatic characteristics of ‘Taishuu’ sweet persimmon to establish region-specific water-fertilizer response models and integrate drip fertigation, soil moisture monitoring, sensor technologies, and intelligent decision-support systems to achieve dynamic and precise regulation of water and nutrient supply. These approaches could provide a theoretical basis and management reference for improving fruit quality, yield, and resource-use efficiency in ‘Taishuu’ sweet persimmon production.
