The study aims to assess the impact of castor-based millets intercropping on pest incidence and overall productivity under rainfed conditions.
Field experiment conducted during kharif season 2017–18 at College of Agriculture, Vijayapura
Randomized Complete Block Design with three replications was employed
Various intercropping systems of castor with millets were analyzed for yield and pest incidence.
Sole castor achieved a seed yield of 2416 kg ha−1 and higher number of capsules per plant (293.25)
Castor + foxtail millet intercropped system showed lower pest incidence of semilooper (9.66 larvae plant−1) and capsule borer damage (8.79%)
Castor + little millet yielded higher net returns (78,720 Rs ha−1) and castor equivalent yield (3325 kg ha−1).
