Growth, yield, and economics of chickpea (Cicer arietinum L.) as influenced by herbicides

Abstract

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 (150 g/ha), oxyfluorfen (250 g/ha), quizalofop-p-ethyl (100 g/ha) at 21 DAS, propaquizafop (100 g/ha) at 21 DAS, topramezone 20.6g/ha at 21 DAS, oxyfluorfen 150 g/ha (PE) fb quizalofop-p-ethyl 100 g/ha at 15-20 DAS (PoE), oxyfluorfen 150 g/ha(PE) fb propaquizafop 100 g/ha at 15-20 DAS (PoE), oxyfluorfen 150 g/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 pre-emergence fb topramezone 20.6g/ha at 14-21 DAS as post-emergence recorded maximum growth attributes, yield and yield attributes, viz. plant height (cm) (11.53), plant population (37/m2), number of branches/plant (21.77), number of pods/branch (1.74), number of seeds/pod (1.78), number of pod/plant (36.98), 1000 seeds weight (290.5 g) and yield of chickpea (19.15 q/ha), harvest index (35.97%) 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.
