Title : Mechanized weed management in Chickpea (Cicer arietinum L.)

Abstract :

A study was carried out during Rabi (winter) season of 2017-18 and 2018-19 at Research Farm, CCSHAU Regional Research Station, Bawal, India to find out cost effective weed management technique through mechanized interculture in chickpea with modifications in row spacing. The experiment consisted to nine treatments and laid out in randomized block design replicated thrice. The crop was infested with Chenopodium album, Chenopodium murale, Anagallis arvensis, Phalaris minor etc. Two mechanized interculture with tractor drawn cultivator 30 and 60 DAS under 60 cm row sopacing was found cost effective and more profitable seed yield of 1.65t/ha, and 26 % lesser cost of cultivation; 25 % higher net returns; and B:C ratio of 2.14 compared to the recommended manual interculture with Kasola at 25-30 and 45-50 DAS under 45cm row spacing over two years (2017-18 and 2018 -19). WCE of two mechanized interculture with tractor drawn cultivator or power weeder ranged from 59-63 % in comparison with 70 % observed under recommended two interculture with Kasola. Uncontrolled weeds throughout the crop season caused yield loss of 53 % over study period.
