Deficiency of Boron and its management in soil and plants

Boron is an essential micronutrient for normal growth and development of plants. Deficiency of B in plants produces several visual symptoms and affects the crop yield. Uptake of B by plants is closely related to the availability of B in soils which is ultimately controlled by many soil properties like soil texture, organic matter content, pH, presence of Fe and Al oxides etc. Boron deficiency in soils is very common in eastern and north-eastern parts of India. The management of B in soils is very important for correcting B deficiency in plants. All the soil and plant parameters must be considered for precise fertilizer recommendation of B, as the range of B deficiency and its toxicity is very narrow in soil and plants.
