Economics of cultivation of mustard varieties (Brassica juncea L.) under Nagpur mandarin (Citrus reticulata Blanco.) based agroforestry system in South-Eastern Rajasthan

Field experiment was conducted deploying 24 treatments in Randomized Block Design with three replications during two successive years from October 2020 to March 2021 and October 2021 to March 2022. The fourteen year old plantation of mandarin planted at 6 x 6 m spacing, which was used for the present intercropping study. Mustard with three varieties (var. Giriraj, RH-725 and NRCHB-101) and was selected along with the application (4 ml/lit.) of biofertilizers (Azotobacter and Phosphorus solubilizing bacteria) for the study. Higher benefit cost ratio in the treatment M₁₀ (1: 3.39 in 2020-21 and 1:3.42 in 2021-22), where mustard (var. Giriraj) was intercropped under mandarin based agroforestry system as compared to sole cropping of mustard during both the years of study. The B: C ratio was recorded minimum in the treatment M₁₅ (1:1.30 in 2020-21 and 1:1.52 in 2021-22), var. NRCHB-101).
