The effect of molybdenum and cobalt upon leafiness and carbohydrate formation in berseem was investigated in pot culture experiment with a Jabalpur sandy loam. Two doses of Mo and Co were applied to soil with and without Rhizobium inoculation. The dry matter outturn of the inoculated and uninoculated groups was similar; maximum yields were obtained with 0.5 ppm Mo and 0.5 ppm Mo+2 ppm Co in the two series respectively. There was a definite trend towards increased yield with the higher level of Co (4 ppm) and with lower one of Mo (0.5 ppm). Leafiness was enhanced by Mo (1 ppm) and Co (4 ppm) alone or in combination. Inoculation along with Mo in the first cutting and Co in the second increased the leafiness index over no trace element treatment. Carbohydrate formation was favoured by inoculation in two combinations of Mo and Co.
