Intercropping system plays an important role in increasing land use efficiency and weed suppression. A field experiment entitled “Integrated weed management in chilli + garlic intercropping system” was conducted at the Vegetable Division in Kittur Rani Channamma College of Horticulture, Arabhavi, University of Horticultural Sciences, Bagalkot (Karnataka) during kharif 2014 and 2015. The objective of the experiment was to identify the best possible method of weed control for maximizing the productivity of chilli+garlic intercropping system. Among the different chemical treatments, pre-emergent application of alachlor @ kg ai/ha + 2 HW at 45 and 60 DAT recorded the lowest pooled dry matter of weeds ( g), lowest monocot (), dicot weeds () and weed population () thus exhibited the highest weed control efficiency (). The yield per ha of green chilli ( q) and garlic ( q), net returns () and B:C ratio () were found to be highest and it was followed by treatment with pre-emergent application of pendimethalin at kg/ha +2 HW at 45 and 60 DAT. | Integrated weed management in chilli + garlic intercropping system
