How to Manage Soybean Flower Abortion

Boron is important for pollen tube growth and pollen grain germination. 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 of flower abortion, thus 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 bud fixation and pod formation. Its deficiency causes abortion of flowers and pods, directly influencing the crop yield.
