Abstract At global level, India ranks as second largest wheat producing nation after China and contributing approximately 11.9% to the world wheat production from about 12% of global area (USDA, 2010). The area under wheat throughout the world as well as in India has become nearly constant around 217.9 million ha and 26.9 million ha respectively. Long term studies being carried out at several locations in India indicated that application of all the needy nutrients through chemical fertilizers have deleterious effect on soil health leading to unsustainable yields. One of the major constraints in boosting up the wheat production is the deleterious effect on soil health. Therefore; there is a need to improve nutrient supply system in terms of integrated nutrient management involving the use of chemical fertilizers in conjunction with organic manures coupled with input through biological processes. Balanced fertilizer is the application of essential plant nutrients in light proportion and in optimum quantity for a specific soil crop condition. Continuous imbalanced use of fertilizer led to the deterioration in the soil fertility and decrease in soil productivity. Higher yield at balanced nutrition safe guard soil fertility. Integrated plant nutrient supply system could help in meeting the goals of balanced fertilization. Therefore, integrated ways of nutrient management on wheat crop have multipurpose on the improvement of soil fertility and crop productivity in the sustainable manners. It is also important for the improvement of soil chemical, physical properties and soil biology before application for a long period of crop season. It is commonly believed that the combination of organic and inorganic fertilizer will increase synchrony, enhancing the efficiency of the fertilizers, and reduce losses by converting inorganic nitrogen into organic forms but also reducing environmental problems that may arise from their use. Different kinds of organic materials such as FYM, animal manures, green manures, crop residues, composts, and industrial wastes have been used in wheat systems. The amount and availability of nutrients in organic materials vary widely, which makes interpretation of the value of nutrients supplied. The literatures lines of research in wheat are presented in an elaborative method were reviewed in this paper.
