Micronutrients for crop production: Role of boron

Sexual reproduction in plant is more sensitive to low B, than vegetative growth. Boron needed for growth of the pollen tube during flower pollination and therefore important for good seed set and fruit development. Boron is thought to increase nectar production by flowers, and this attracts pollinating insects. B in crop production is one of the essential micronutrient required for normal growth of most of the crops.
