Role of Boron in Potato Production

Boron effect on calcium levels

Boron affects calcium absorption, so supplies are important to ensure a balanced nutrition. The figure above shows boron effects on calcium levels according to studies in Holland.

Boron and apical necrosis

Boron stabilizes calcium in the cell wall and acts in synergy with calcium to improve plant resistance to disease, pest and environmental stresses. In this respect, it can help minimize apical necrosis of sprouts.

Boron and tuber discolouration

Boron reduces the oxidation of phenols that are responsible for enzymatic discolouration. Thus, a good supply of boron reduces the occurrence of enzymatic discolouration in potato tubers.

General guidelines for boron application

Boron is the micronutrient needed in the greatest quantity to ensure several key growth processes. It influences root and shoot growth, plant development and pollination. Alongside potassium, calcium and magnesium, boron is an important element present in the cell wall. Here it acts as a cement between pectins, providing cohesive strength for cell tissues. Therefore boron affects tuber storage quality characteristics. Boron also affects calcium absorption, so supplies are important to ensure a balanced nutrition.
