Effect of integrated nutrient management on growth and yield of broccoli (Brassica oleracea var. italica) under Jharkhand conditions

The studies were carried out at Birsa Agricultural University, Ranchi during 2008-09 and 2009-10 to evaluate the integrated nutrient management practice on qualitative and quantitative parameters of broccoli under Jharkhand conditions. The experiment was laid out in Randomized Block Design with 19 treatments i.e., four inorganic combinations 200:100:100 kg NPK, 150:75:75 kg NPK, 100:50:50 kg NPK and 50:25:25 kg NPK ha-1, 12 organic and inorganic combinations by substituting 25% N of above inorganic combinations through FYM, vermicompost and karanj cake along with recommended dose 100:50:50 kg NPK + 200 q FYM ha-1 and two controls N0 P100 K100 and N0P0K0 eachreplicated thrice. The application of 50 kg N through vermicompost + 150:100:100 kg NPK ha-1 through inorganic sources (T9) and application of 100:50:50 Kg NPK ha-1 along with 200 q FYM ha-1 (Recommended dose) (T17) proved significantly superior in respect of plant height, number of leaves, leaf length and plant spread. The application of 200 : 100 : 100 kg NPK ha-1 through inorganic sources (T1 ) resulted in minimum duration for 50% curd maturity. The application of 50 Kg N through vermicompost + 150:100:100 kg NPK ha-1 through inorganic sources (T9) resulted in maximum yield of curd. Application of 150:75:75 kg NPK ha-1 through inorganic sources (T2) resulted in maximum benefit cost ratio (2.25) whereas application of 50 kg N through vermicompost + 150:100:100kg NPK ha-1 through inorganic sources (T9) resulted in maximum net profit (Rs. 72469/- per ha).
