Four sprays and one drainage during the peanut pod-filling maturity stage to promote high yield
The pod-filling maturity stage of peanuts refers to the period from when half the plants have plump pods until most pods are fully filled and plump, that is, the period leading up to maturity and harvest. For medium-maturing varieties this lasts about 35-45 days; very early and early maturing varieties are shorter, and late-maturing varieties are longer. Summer-sown peanuts are comparable to or slightly longer than spring-sown peanuts of the same variety.

Detailed Explanation of Sprinkler Irrigation Techniques for Soybeans During the Pod-Filling Stage
When soybeans enter the pod-filling and maturation stages, they still need some water and nutrients to promote material accumulation and maturation, improve the seed-setting rate, and increase yield. For many years, when soybeans enter the pod-filling stage, conditions are generally very dry, which adversely affects the pod filling and maturation of the top and upper pods. In response, some farmers use sprinkler irrigation with well water during this period to alleviate the drought. Production practice has proven that soybeans sprinkler-irrigated with pumped water during the pod-filling stage not only fail to promote maturation after one week, but instead cause some branches and plants to turn yellow prematurely or even die, thereby reducing yield. The reason is that soybeans
