Impact of intercrop on infestation and severity of army worm (Spodoptera exigua) and diamondback moth (Plutella xylostella) on cabbage (Brassica oleracea L.)
The research project was undertaken at Sam Higginbottom University of Agriculture, Technology and Sciences, Allahabad, Uttar Pradesh, India during Rabi 2017-18. The experiment was conducted in a Randomized Block Design with seven treatments; (T1) cabbage + marigold, (T2) cabbage + mustard, (T3) cabbage + cowpea, (T4) cabbage + onion, (T5) cabbage + tomato, (T6) cabbage + garlic and (T7) cabbage sole each of which was three replications. The treatment T6 least damage of army worm (Spodoptera exigua) (0.56) and the followed by T4 (0.58), T5 (0.96), T3 (0.86), T2 (1.36), T1 (4.43) and highest in T7 4.43. DBM (Plutella xylostella)infestation the treatment T6 showed least damage of DBM (0.38) and followed by T2 (0.56), T3 (0.65), T4 (0.75), T5 (0.84), T1 (4.42) and highest in T7 (4.42). The maximum yield in T6 3:2 (16708) and followed treatment in order of efficacy was T5 3:2 (16333), T7 3 (15318), T1 3:2 (15017), T4 3:2 (14440.30), T2 3:2 (13140), and T3 3:2 (11167.38) cabbage equivalent yield (kg/ha).
