Boron Deficiency in Beans

There have been very few cases of boron deficiency in beans, which are particularly sensitive to excess application of boron. As little as 2.5 lbs/acre of boron has been known to reduce yield. However, boron deficiency also reduces growth, with leaves near the growing point being small and chlorotic. The growing point becomes blackened and dies, and lateral shoots develop near the base of the plant. The flower buds may shrivel and be shed without opening.

Typical recommended ranges for boron boradcast soil application for beans is 0.5-1 lb of B/acre.*


*Always consult local crop advisors to check the proper dose rates. Rates of boron fertilization should be based on yield goals along with soil tests and/or plant tissue analyses.
