Effect of nitrogen and biofertilizers on growth of cabbage (Brassica oleracea var. capitata L.) var. Pride of India

A field experiment was conducted to study of “Effect of nitrogen and biofertilizers on growth of cabbage (Brassica oleracea var. capitata L.) var. Pride of India” during the Rabi season of 2010–11 at Department of Vegetable Science, College of Horticulture & Forestry, Jhalawar.The experiment consist of 17 treatment viz., four levels of nitrogen (control, 100 kg, 125 kg and 150 kg) and three doses of biofertilizers (Azotobacter, Azospirillium and PSB) in combination with nitrogen levels and one is absolute control was laid out in simple RBD with three replications. The treatment T₁₆ (150 kg N+ PSB) was recorded maximum plant height (24.64 cm), plant spread(42.87 cm), number of open leaves (20.67), leaf area (247.43 cm²), maximum days taken to head maturity (110.00), diameter of stem (17.51mm), yield of head per hectare (432.92 q ha⁻¹). However, it was statistically at par with 150 kg N + Azospirillium and 150 kg N + Azotobacter inoculation.
