Abstract:
A field experiment was carried out during rabi season of 2020-21 and 2021-22 in the Instructional-cum-Research Farm, I.G.K.V, Raipur, Chhattisgarh, to study the assessment of chickpea (Cicer arietinum L.)-chandrasur (Lepidium sativum L.) intercropping productivity using competitive indices under varying moisture regimes. The experiment was laid out in split plot design with three replications with keeping three moisture regimes viz., no irrigation (I₀), one irrigation at 35 DAS (I₁) and two irrigations at 35 and 70 DAS (I₂) as main plot and six intercropping systems viz., sole chickpea, sole chandrasur, chickpea + chandrasur (1:1), chickpea + chandrasur (2:1), chickpea + chandrasur (3:1) and chickpea + chandrasur (2:2) as sub plot treatments. The application of two irrigations at 35 and 70 DAS (I₂) recorded the highest seed yield, stover yield and biological yield as compared to one irrigation at 35 DAS and no irrigation. Sole chickpea and sole chandrasur gave significantly higher yield as compared to intercropping ratios. The intercropping of chickpea and chandrasur in 3:1 row ratio was significantly superior as compared to sole in terms of gross return, net return and chickpea equivalent yield while, in case of B: C ratio higher was recorded under 2:2 row ratio.
