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(T 2 ) and is was statistically at par with T 6 and T 8 . The maximum organic carbon (0.93 per cent) was recorded in the treatment 75 % RDF + FYM + Azotobacter + Azospirillum(T 6 ). 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.

In order to investigate the effect of integrated nutrient management on growth and yield components in Cauliflower, Brassica oleracea var. botrytis L., cv. Pusa snowball- 16, an experiment was conducted using Randomized Block Design with two replications. The experiment comprised of 14 different treatment combinations comprising of different sources of nutrients including organic, inorganic and bio-fertilizers. The growth parameters like height of plant (12.10, 23.50 cm), number of leaves per plant (9.10, 14.40) and diameter of stem (1.20, 2.10 cm) at 40 and 60 DAT respectively, the days required for curd initiation (62.00 days), days required for curd maturity (85.70 days) and staying period of curd (9.50 days) were observed maximum in treatment combination 75 % RDF + FYM + Azotobacter + Azospirillum (T6). The yield parameters like weight of curd per plot (17.50 kg/plot) and yield per hectare (180.04 q/ha) which was increased 44.10 per cent over RDF. From the studies it can be inferred that the application of 75 % RDF + FYM along with Azospirillum and Azotobactor was found to be the most effective treatment combination for getting enhanced growth and yield in cauliflower.
