A field experiment was conducted in kharif-2012 at Instructional-cum-Research Farm, Indira Gandhi Krishi Vishwavidyalaya, Raipur (Chhattisgarh) India. The aim of the experiment was to study the effect of pelleted integrated nutrient management on nutrient use efficiency and yield of transplanted rice. The result showed that plant height (r=0.760), number of leaves plant-1 (r=0.766), dry matter accumulation (0.765), effective tillers hill-1 (r=0.646) and number of filled spikelets (r=0.642) were positively correlated and contributed in yield increment. The total nitrogen uptake, phosphorus uptake and potassium uptake also showed significantly positive correlation with the plant height, number of leaves, dry matter accumulation, effective tillers hill-1 , number of filled spikelets and yield.
