Effect of Intercropping with Mustard with Onion and Garlic on Aphid Population and Yield
Keywords:Intercropping, onion, garlic, agronomic benefits
Field experiments were conducted to study the effect of intercropping of mustard (Brassica napus, Var. Bari Sarisha-7) with onion (Allium cepa L.) and garlic (Allium sativum L.) on aphid [Lipaphis erysimi (Kaltenbach)] population and yield. Intercropped with these two medicinal as well as spice crops reduced the aphid population significantly (P < 0.05). Mustard blocks intercropped with garlic gave highest cost-benefit ratios (1:2.07 and 1: 2.96) than onion intercropped blocks. Sole mustard blocks produced lowest cost-benefit ratios (1:1.65 and 1:2.06).
