Various investigations on different fodder grasses and forbs show that apart from the dominating influence of factors like soil and climate, the storage of growth of plant has also no important bearing on the chemical composition and nutritive value. Nutritive value of the grasses and forbs in India has attracted lot of attention because of importance of fodder in its various forms in the dietary of cattle needs no special emphasis. The composition of grass and fodder crops is known to be affected by several factors. Much works have been carried out on the forage quality of grasses and forbs but the nutritive value of grasses in relation to pollution work on grassland is untouched. The underground standing crop of energy ranged from 821.78 Kcal/m2 to 1377.76 Kcal/m2 on control and 548.67 Kcal/m2 to 690.57 Kcal/m2 on polluted grassland. The annual net production value of total community was 2846.62 Kcal/m2 on control and 1544.76 Kcal/m2 on polluted grassland. Mica dust pollution has reduced 54.27 Kcal/m2 per cent of production in terms of Kcal/m2/yr in comparison to control grasslands. The energy conserving efficiency of Bothriochloa pertusa, Cynodon dacrylon, other species and total community was estimated in rainy, winter and summer seasons on control and polluted grasslands. The annual energy conserving efficiency of total community was recorded 0.94 per cent on control and 0.33 per cent on polluted grassland.
