Boron is a micronutrient that is necessary for plant metabolism. Due to the formation of cell wall pectin, malic acid synthesis, cell division, transport of carbohydrates and enzymes. It also played an important role in the germination and growth of pollen tubes. Boron is one of the essential micronutrients for plants that plays an important role in meiotic division and seed production. Zinc is a micronutrient that is needed to form and produce the right fruit with the desired size. This element is present in part of the carbonic anhydrase enzyme in all photosynthetic tissues, which is required for chlorophyll biosynthesis. Zinc is also involved in the synthesis of tryptophan, a precursor to oxygen synthesis, and is involved in many enzymatic reactions (enzymes involved in nitrogen and sugar metabolism, energy transfer, protein synthesis, regulation of oxygen hormone synthesis, and pollen formation) and metabolic processes. . The use of this combination greatly affects the quality and quantity of the product. Also, the presence of nitrogen in this compound during foliar application increases their absorption and ultimately increases the yield of this fertilizer.
