An experiment was conducted during rabi season of 2014–15 at the research farm of soil science, Allahabad School of Agriculture, laid out in randomized block design, consisted nine treatments and three replications. It was observed that growth and yield of mustard in treatment N80P60K40 vermicompost @ 10 t/ha was maximum. Maximum plant height (139.22 cm), number of leaves/plant (21.22), number of branches/plant (10.77), fresh weight/plant (87.78 g), dry weight/plant (62.25 g), test weight (4.17 g) and total seed yield (23.19 q/ha) were found to be significant over all other treatments. Adequate plant nutrient supply holds the key for improving the growth and seed production of crop.
