Abstract
Globally India is the fourth largest economy for oilseeds after United states, China and brazil. Oilseeds are grown over an area of 26.77 million ha in India, with the production of 33.55 million tons and productivity of 2549 kg ha-1, respectively. Oilseeds are majorly grown as rainfed crop especially by small and marginal farmers. Plants need micronutrients in small amounts for their growth and development. Iron (Fe), manganese (Mn), zinc (Zn), boron (B), copper (Cu), molybdenum (Mo) and chlorine (Cl) are some of them. Specific micronutrients in oilseeds are important for the translocation of photosynthates, increased seed set along with the translocation of sugar, pollen grain germination, stigma receptivity, amino acid and protein synthesis and finally boosting seed production.
