Author(s): Vilas D Gasti and Snehasish Chakravorty
Abstract: A field experiment 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 to identify the best possible method of weed control for maximizing the productivity of chilli+ coriander intercropping system. The weed population, dry weight of weeds, weed control efficiency and yield components of chilli and coriander were significantly affected in response to weed control treatments. Among the different chemical treatments, pre-emergent application of alachlor @ 1.5 kg ai/ha + 2 HW at 45 and 60 DAT recorded the lowest pooled dry matter of weeds (3.8 g), lowest population of monocot (3.47), dicot weeds (2.82) and thus exhibited the highest weed control efficiency (83.45%). The yield per ha of chilli (285q) and coriander (73.02q) net returns (Rs. 1,33,661) and B:C ratio (2.63) were also found to be highest and it was followed by pre emergence application of pendimethalin at 1.5 kg/ha +2 HW at 45 and 60 DAT.
