Nutrient Uptake, Economics and Yield Of Broccoli Influenced By Integrated Nutrient Management Practices

Abstract

The investigation was carried out during winter season in two consecutive years at vegetable section of horticulture garden under the Faculty of Agriculture, Birsa Agricultural University, Kanke, Ranchi (Jharkhand). To study the effect of N, P and K fertilizer with FYM, Karanj cake and vermicmopst on yield, nutrient uptake and fertility status of soil available NPK. The highest head yield of broccoli was recorded in the treatment receiving 50 Kg N through vermicompost + 150:100:100 kg NPK ha-1 through inorganic sources. Integrated uses of FYM, Vermicompost, Karanj cake with 50 Kg N through FYM + 150 : 100 : 100 kg NPK ha-1 through inorganic sources received the maximum uptake of nitrogen (311.49 kg/ha), application of 37.5 Kg N through FYM + 112.5 : 75 : 75 kg NPK ha-1 through inorganic sources resulted in maximum uptake of phosphorus (33.44 kg/ha) and application of 100 : 50 : 50 kg NPK ha-1 throughinorganic sources resulted in maximum uptake of potassium (367.77 kg/ha). Intergraded nutrient management enhanced the organic carbon and available N,P and K in the soil. Highest net income and benefit: cost ratio was obtained application of 50 Kg N through Vermicompost + 150 :100 : 100 kg NPK ha-1 through inorganic sources resulted in maximum net profit (Rs. 72467/- per ha) and application of 150 : 75 : 75 kg NPK ha-1throughinorganic sources resulted in maximum benefitcost ratio (2.25) respectively.
