Causes of and Preventive Measures for Soybean Pods Without Seeds
I. Causes of Pods Without Seeds 1. Improper selection of variety or planting system. Generally speaking, late-maturing varieties with poor resistance are affected by relatively low temperatures during grain filling, which seriously affects the filling rate and thus induces the formation of pods without seeds. Continuous and alternate-year soybean planting causes a sharp decrease in the boron content of soil nutrients. Since boron is an important trace element that promotes the formation and growth of soybean pods, its deficiency induces soybean pods without seeds. At the same time, continuous and alternate-year soybean planting leads to more severe soybean diseases and pests, thereby inducing pods without seeds.
