Abstract: The present experiment was conducted during rabi season of 2015-16 with an aim to study the effect of biofertilizers and organic nutrition on broccoli production. The experimental site has annual rainfall of 750 mm, 60-90 per cent relative humidity with high pH soil (pH 8.2). The experiment was carried out in a Randomized Block Design with ten treatments (control, Recommended dose of fertilizer, Rhizobium, Azotobacter, Azosprillium, PSB, VAM, FYM, Vermicompost and Farm compost) by three replication. Observations were recorded for growth parameters like plant height, stem circumference, plant spreading, number of leaves, length and width of leaves, yield (kg plot-1 and q ha-1 ), quality parameters viz., curd weight, curd diameter, Vitamin C, T.S.S., Total sugars, Reducing sugar, Nonreducing sugar, Titratable acidity etc. The experimental result revealed that the use of biofertilizers improved the production of broccoli in general as compared to untreated control. Among the treatments, application of Azospirillum can be suggested to broccoli growers for obtaining better growth, yield and quality improvement of broccoli cv. KTS-1 under Lucknow subtropical condition.
