Abstract:
A field investigation was carried out in Rabi season of 2022-2023 at Central Research Farm (CRF), Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj, Uttar Pradesh, India. The experiment was laid in Randomized Block Design with eight treatments each replicated thrice. Result revealed that, among the different treatments the lowest larval population of chickpea pod borer was recorded in Profenofos 40% + Cypermethrin 4% EC @ 0.1 ml/lit (2.36). Neem oil @ 5 ml (2.65) was found as the next best treatment followed by Neem seed kernel extract 5% @ 50 ml/lit, Karanj oil @ 5 ml (2.98), Calotropis gigantea 5% @ 50 ml/lit (3.31), Ageratum conyzoides 5% @ 50 ml/lit (3.49), whereas Lantana camera 5% @ 50 ml/lit recorded (3.81) was found to be least effective against this pest. Among the treatments studied, Profenofos 40% + Cypermethrin 4% EC gave the highest benefit cost ratio (1:3.65) and marketing yield (21.38 q/ha) followed by Neem oil (1:3.35 and 19.27 q/ha), Neem seed kernel extract 5% (1:3.19 and 18.33 q/ha), Karanj oil (1:2.96 and 16.20 q/ha), Calotropis gigantea (1:2.47 and 14.16 q/ha), Ageratum conyzoides (1:2.41 and 13.16 q/ha), Lantana camera (1:2.24 and 12.77 q/ha) and lastly in untreated control (1:1.68 and 9.10 q/ha).
