Application of a broad-spectrum post-emergence herbicide is a promising weed management option for chickpea (Cicer arietinum L.). So, the goal of this experiment was to find out how much and when to use topramezone to control weeds in chickpea. The experiment was designed in RBD of ten treatments, viz. two different doses of topramezone 20.6 and 25.7 g/ha were applied at 14, 21, and 28 days after sowing (DAS) and quizalofop-p-ethyl 100 g/ha at 25 DAS applied as post-emergence (PoE). The ready-mix of pendimethalin 30% + imazethapyr 2% 1000 g/ha applied as pre-emergence (PE) fb one HW at 30 DAS, weed free check, (WFC) and weedy check (WC). Among different application times of topramezone sprayed, early-PoE application (14 DAS) caused some phytotoxicity on crop (rating 4), and late-PoE application (28 DAS) was less effective on weeds, but the application of topramezone at 21 DAS controlled all broad and narrow leaf weeds without crop injury. In all the topramezone sprayed plots, topramezone 25.7 g/ha (21 DAS) had the lowest narrow and broad-leaf weeds density, and total weed dry weight than other doses and application times. Among all PoE herbicide treatments, topramezone 25.7 g/ha (21 DAS) yielded the highest seed yield (1.31 t/ha), while quizalofop-p-ethyl 100 g/ha (25 DAS) yielded the lowest (0.79 t/ha). It produced 7-65% higher seed yield as compared to other doses and time of application of all PoE applied herbicides. It gave 81% and 116% higher net return than topramezone 25.7 and 20.6 g/ha sprayed at 28 DAS (late-PoE), and 159% and 259% higher than topramezone 25.7 and 20.6 g/ha sprayed at 14 DAS (early-PoE), respectively. Hence, topramezone application of 25.7 g/ha (21 DAS) can be safely used for proper weed management in the chickpea crop.
