The study looked at how different amounts of water and irrigation schedules affect the growth and yield of potatoes. They found that potatoes have the highest photosynthetic activity during the tuber-formation stage, which decreases as they mature. More water and frequent irrigation led to higher photosynthesis rates in potatoes. The rate at which water is taken up by the plant and the opening of pores on the leaves were closely related to the yield of potatoes. Increasing photosynthesis can help improve the yield of crops like potatoes.
