Soyabean (Glycine max) is one of the most important oil and protein crops of the world. The supplies of oils and protein from animal sources are becoming scarce and expensive in developing nations. Soyabean can play a major role in elevating nutritional standards of foods in developing nations, where human beings are facing protein deficiencies. Biofertilizers not only supply the major nutrients but also micronutrients like Zn, Fe, cu, etc. Chemical fertilizers do not produce basic soil health but weaken soil structure. Plants growing in highly chemicalised soil do not have a natural resistance to disease. Biofertilizer exhibited an improved plant growth, biomass production, chlorophyll, and total carbohydrate content, phosphorus, protein, potassium and total nitrogen. The Glycine max seeds can be treated with fungicide and its influence on the nitrogen fixation can be studied.Ø The effect of other chemical fertilizers a part from phosphatic fertilizers can also be studied.
