Response of Different Levels of Nitrogen and Spacing on Growth and Yield of Cauliflower Grown under Central Region of Punjab

Abstract

A field experiment was conducted to study theresponse of different levels of nitrogen and spacing on growth and yield of cauliflower at Experimental Farm, Department of Agriculture, Mata Gujri College, Fatehgarh Sahib, Punjab, India from October 2018 to February 2019. The present study was conducted to determine the optimum level of nitrogen and spacing for better growth and yield of cauliflower. The experiment consisted of two factors: Factor A: Nitrogen (4 levels), N₀: 0; N₁: 50; N₂: 75 and N₃: 100 % ha^-1 and Factor B: Spacing (3 levels), S₁: 45×30 cm²; S₂: 45×45 cm² and S₃: 60×45 cm². The experiment was laid out in Factorial Randomized Block Design (FRBD) with three replications. Maximum plant height (54.27 cm), plant spread (69.53 cm), number of leaves plant^-1 (17.00), leaf length (46.60 cm), leaf width (25.03 cm), fresh weight of curd (833.33 g), dry matter of curd (0.89 g) was found from N₁₀₀S_60×45. However, maximum curd yield plot^-1 (30.03 kg) and ha^-1 (326.90 q) was obtained from N₁₀₀S_45×30. while, maximum net return (`299443.45) and B: C ratio (3.22) was obtained with 100 % N ha^-1 + 45×30 cm². Results demonstrated that treatment combination N₁₀₀S_60×45 found to be best in most growth and yield characteristics in cauliflower variety Golden-75  but the maximum yield plot^-1 and ha^-1 was recorded in N₁₀₀S_45×30 and T₀ (Control) gave poor results in all traits.
