摘要	Fertigation scheduling integrates irrigation and nutrient delivery to optimize plant nutrition while minimizing waste and environmental impact. By applying fertilizers through drip or sprinkler systems at precise times and rates matched to plant development stage and soil water availability, growers can improve nutrient use efficiency, reduce leaching, and boost yields. This method is now standard in commercial vegetable, orchard, and nursery production worldwide.	Crop load management uses quantitative assessment of fruit number and tree vigor to optimize yields and fruit quality through selective thinning and load balancing. This method combines visual assessment of fruitlet density, calculation of target fruit number based on tree age and vigor, physical or chemical thinning, and yield monitoring to achieve the optimal balance between productivity and fruit size and flavor.
