Pest incidence was significantly higher in unprotected castor plots compared to protected ones.
Capsule borer damage reached 7.15% in unprotected DCH 519, showcasing pest threat.
Protected treatments yielded higher seed yields of 1355–2280 kg ha⁻¹, reducing avoidable yield losses.
DCH 48-1 had the highest yield loss, while DCH 519 showed better resilience against pests.
