Brassica oleracea var. botrytis L. (Cauliflower) is an important commercial vegetable crop grown all over the world. In order to meet the growing demand of burgeoning population, large amounts of herbicides, pesticides and fertilizers are being applied to the fields every year to achieve maximum production leading to deleterious environmental effects.The present investigation ‘Integrated nutrient management in cauliflower was undertaken at the Instructional Farm of Department of Horticulture, College of Agriculture, Latur during the Rabi season. The experiment laid out in Randomized Block Design (R.B.D.) with fourteen treatments replicated thrice. The treatment comprises with RDF (120:80:40 NPK kg/ha.), FYM (10 t/ha), Azotobacter and Azospirillum (10 kg/ha). The variety Snowball – 16 was selected for the study. The data regarding soil analysis after harvesting, the maximum available nitrogen (265.66 kg ha-1), available phosphorus (23.26 kg ha-1) and available potassium (415.33 kg ha-1) were recorded in highest dose of INM i.e. 100 % RDF + FYM + Azotobacter + Azospirillum(T2) and is was statistically at par with T6 and T8. The maximum organic carbon (0.93 per cent) was recorded in the treatment 75 % RDF + FYM + Azotobacter + Azospirillum(T6). There were no significant differences of INM treatments observed on soil pH and electrical conductivity. This result suggested that 25% chemical fertilizers can be reduced without any compromise on fertility status of the soil for cauliflower crop production in sub-tropical condition.
