Growth, yield and oil quality of mustard in chickpea (Cicer arietinum) and mustard (Brassica juncea L.) intercropping system under different row ratio in northern transition zone of Karnataka

A field experiment was conducted during rabi season of 2017 at Main Agricultural Research Station, University of Agricultural Sciences, Dharwad, to study different row ratio of chickpea and mustard on growth, yield and quality of mustard. The experiment was conducted in randomized block design with two sole crops of chickpea and mustard including eight different row ratio of chickpea + mustard (2:1, 3:1,3:3, 4:2, 4:4, 5:1, 6:2 and 8:2). Results indicates that, sole mustard recorded higher growth parameters viz. plant height, leaf area, number of branches primary and secondary per plant, dry matter and higher seed, straw yield and harvest index. Among intercropping, higher growth attributes were found in 5:1 row ratio. Significantly higher seed (1128 kg ha⁻¹), straw yield (2294 kg ha⁻¹) and harvest index (27.62%) was found in 4:4 ratio, followed by 3:3 row ratio. Higher oil content (35.16%) and oil yield (606 kg ha⁻¹) was recorded in sole mustard.
