摘要

Incorporating fruit trees into agricultural systems presents a viable avenue for crop diversification and economic upliftment of farmers in Himachal Pradesh. This study aims to assess the production of brown sarson (Brassica campestris var. brown sarson) by investigating its response to various nutrient sources within a high density apple based agroforestry system. Experiment was laid out in RBD factorial design in high density apple (Malus × domestica Borkh.) based agroforestry system and in open field condition under which sole brown sarson was grown and applied with eight different nutrient sources doses viz., T1—control (no manures), T2—100% RDF (recommended dose of fertilizer), T3—100% FYM (N equivalent basis), T4—100% Vermicompost (N equivalent basis), T5—Jeevamrut @ 500 l/ha, T6—50% FYM + 50% Vermicompost, T7—50% RDF + 50% FYM and T8—50% RDF + 50% Vermicompost. Results showed that T2—100% RDF (recommended dose of fertilizer) was found to be the best for the growth and yield of brown sarson and showed its superiority over other treatments in both planting conditions. Soil nutrient status was improved under apple based agroforestry system as compared to sole brown sarson cropping. Maximum available soil nitrogen (356.45 kg ha−1), phosphorus (53.19 kg ha−1) and potassium (235.02 kg ha−1) was estimated under T4—100% Vermicompost (N equivalent basis). However, maximum net returns (US$ 7654.77) and Benefit Cost Ratio (3.81) were realised under high density Apple based agroforestry system coupled with the application of 100% RDF (recommended dose of fertilizer). The results suggested that the cultivation of brown sarson under high density Apple based agroforestry system could be recommended for better economic returns and the use of various nutrient sources has proven effective in improving soil health, productivity and financial returns.
