Pulses are of paramount importance in Indian agriculture for being incredibly rich in vegetable protein. Their unique characteristic of symbiotic nitrogen fixation in collaboration with Rhizobium bacteria categorizes them as leguminous crops. Numerous research efforts have realized the balanced supply of micronutrients to be extremely important for maximizing overall development of pulse crops. Among those micronutrients, molybdenum (Mo) is one of the major concerns. It acts as a cofactor for the enzymes namely nitrogenase and nitrate reductase, which take lead roles in biological fixation and subsequent assimilation of nitrogen in legumes. Thus, Mo plays a vital role in N metabolism and biosynthesis of protein. Besides, it also facilitates several physiological and biochemical processes in pulse crops. Application of Mo enhances the bioavailability of other essential nutrients to crops. Studies have approved the significance of Mo to flourish growth, yield and nutritional aspects of different pulse crops such as chickpea, lentil, field pea, grass pea, pigeon pea, black gram, green gram, soybean, cowpea, kidney bean, broad bean, horse gram and cluster bean predominantly cultivated in India. Therefore, a successful husbandry of grain legumes necessitates the inclusion of Mo fertilization.
