Rapeseed and mustard is a major oil seed crop of India after groundnut. The chemical fertilizer is the mainstay of agricultural production due to insufficient availability of alternative nutrient source. The organic resources available presently, could meet nearly one-third of total nutrients required to achieve the targeted level of food production. The soils of Indo-Gangetic Plain, are showing signs of fatigue due to falling organic carbon levels and deficiencies of macro, secondary and micro nutrients. The integrated use of organic and inorganic source of nutrient ensures better and sustainable yields. In the light of present investigation it may be concluded that 100% NPK + 5t FYM + 40 kg S ha-1 can be recommended to the farmers for successful cultivation of mustard in addition to improving fertility status viz., N, P, K, S and Zn of soil.
