Abstract: Cabbage (Brassica oleraceae L. var. capitata, 2n=18) is one of the most economically and nutritionally important crop of Brassicaceae family. The integrated nutrient management plays an important role for obtaining maximum yield and best growth characteristics of crop. This study was planned with the main objective to study the effect of integrated nutrient management on the growth and yield parameters of cabbage. In this experiment, the highest yield (39.76 t/ha) was recorded in T₁: NPK (100%) + Vermicompost + Azospirillum, however, it was statistically at par with T₂: NPK (75%) + Vermicompost + Azospirillum with a recorded yield of 38.20 t/ha. Similar trend for this treatment combination (T₂) were observed for other parameters such as plant height (25.48 cm), plant spread (50.71 cm), leaf length (26.28 cm), leaf breadth (19.42 cm), polar diameter of head (13.65 cm), equatorial diameter of head (14.96 cm) and yield per plot (7.79 kg) which showed no significant difference when the RDF was reduced by 25 per cent. Therefore, it can be concluded that supplying the cabbage crop with NPK (75%) + Vermicompost + Azospirillum proves efficient in increasing the yield of cabbage besides reducing 20-25 per cent of inorganic fertilizers which will eventually reduce the cost of production and harmful effects of inorganic fertilizers on soil health and environment.
