Description

Soybean [Glycine max (L.) Merrill] is considered to be a miracle crop because of its dual qualities viz., high protein content and oil. These two parameters in one crop have thus gained considerable importance in the agricultural economy of the World. It has high yield potential, wide adaptability, and short duration, very high nutritional value, having a vast multiplicity of uses as food and industrial products. Moreover, being a legume, the crop fix large amount of atmospheric nitrogen in soil. Phosphorus and sulphur play impotent role in crop production. Phosphorus for the soybean crop has long been recognized. Phosphorus is a key element in process of photosynthesis, root nodulation and for growth, yield and quality. Thus optimum supply of P is necessary for enhance the rate of protein synthesis in pulse crops. It increased seed yield and protein content of soybean. Sulphur as secondary plant nutrient is becoming increasingly important in agriculture as it is the "Master Nutrient" for all oilseed crops and pulses and is rightly being called the "Forth Major Plant Nutrient", along with nitrogen, phosphorus and potassium.
