How to reduce flower abortion in soybeans

Thus, its deficiency leads to low flower set and malformation of soybeans grains. 

Boron deficiency causes malformation of the pollen tube and results in increase on flower abortion, then reducing soybean yield potential. Therefore, boron supply is essential to obtain high yields.

Calcium, on the other hand, is important for cell wall synthesis, pollen germination and pollen tube growth. It is an essential nutrient for flower fecundation, flower buds fixation and pods formation. Its deficiency causes abortion of flowers and pods, directly influencing the crop yield.<
