Although the absolute necessity of boron, which has an important place in plant development, was determined about 82 years ago, its functions in the plant are still not fully understood.
Boron regulates sugar passage in the cell, cell division and development, photosynthesis metabolism. Without the required amounts of boron, plants can grow and leaf, but there will be losses in fruit or seed production.
Research on the nutrition and physiology of vegetables has shown that boron greatly improves the growth and quality of vegetables. With boron application in vegetables, an increase is observed in the beginning and development of growth points, intracellular sugar and starch transfer, intra-plant circulation of nutrients, formation of hormones affecting growth, root development, flower and bud formation.
The boron element is an indispensable micro-nutrient for fruit trees in terms of flowering, fruiting and fruit quality. In a fruit tree containing a sufficient amount of boron, an increase in flowering and fruit capacity, a decrease in the injury and decay observed in the fruit and bark, an acceleration in the delivery of sugar and nutrients from the leaves to the fruit, a decrease in the number of undergrowth branches and a decrease in the number of fruit falling from the branch are observed.
The amount of boron that plants need to complete their development is quite low. For this reason, in practice, it should be treated very precisely and boron should not be added to the plant without soil analysis. Significant differences in boron coverage and tolerances can be found between plant species and varieties of the same species. For example, 3 kg boron is applied in sugar beet per hectare, while this amount can be 1 kg for wheat.
Boron can be applied to soil by using different boron sources (boric acid, borax etc.). The point to be emphasized is that the boron source to be applied is neutral and easily soluble during application so as not to disturb the pH of the soil.
