WEED DYNAMICS AND YIELD OF CHICKPEA (CICER ARIETINUM L.) AS INFLUENCED BY HERBICIDES

A field experiment was conducted during rabi season of 2021-22 under limited irrigation at Rice Research farm, BAU, Kanke, Ranchi to study the "Efficacy of herbicides on chickpea (Cicer arietinum L.) Production".The experiment was laid out in randomized block design (RBD) replicated thrice with the variety Birsa Chana-3 under limited irrigation condition.The treatments consists of oxyfluorfen (150g/ha), oxyfluorfen (250g/ha), quizalofop-p-ethyl (100g/ha) at 21 DAS, propaquizafop (100g/ha) at 21 DAS, topramezone 20.6g/ha at 21 DAS ,oxyfluorfen 150g/ha (PE) fb quizalofop-p-ethyl 100g/ha at 15-20 DAS (PoE), oxyfluorfen 150g/ha(PE) fb propaquizafop 100g/ha at 15-20 DAS (PoE), oxyfluorfen 150g/ha (PE) fb topramezone 20.6g/ha at 14-21 DAS (PoE), imazethapyr 60 g/ha (PoE) at 21 DAS, Manual Weeding (Weed free) at 25 DAS and 45 DAS, Weedy Check.oxyfluorfen @150 g/ha as preemergence fb topramezone 20.6g/ha at 14-21 DAS as post-emergence recorded maximum yield attributes, viz.number of pods /plant (36.98), number of seeds/pod (1.78), 1000 seeds weight (290.5 g) and yield of chickpea (19.15 q/ha),harvest index (35.97%)and minimum weed index (8.28%)and higher weed control efficiency (59.19%) during initial crop growth stage and realized maximum net return (64131/ha) and B:C ratio (1.81) of chickpea under medium land situation in irrigated condition (3 irrigations) of Jharkhand.
