Abstract:
The current study, titled "Studies on Bioefficacy of Different Herbicides for Weed Management in Chickpea [Cicer arietinum L.]", at the College of Agriculture in Badnapur. Ten treatments were used in the field experiment, which was set up using a randomised block design. Among herbicides, oxyfluorfen had the highest plant height values (41.67), number of leaves (122), and number of branches (8.67) at harvest. In terms of plant height, it was comparable to quizalofop-p-ethyl 100 g A.I/ha at 25 DAS (T₆) (40.33). The highest seed yield (1788 kg/ha) was recorded by the weed-free treatment (T₉), which was comparable to hand weeding at 30 DAS and hoeing at 45 DAS (T8) (1632 kg/ha), oxyfluorfen (23.5% EC) @ 0.17 Kg A.I/ha (PE) (T₃), and quizalofop-p-ethyl 100 g A.I/ha at 25 DAS (T₆). The herbicide oxyfluorfen (23.5% EC) @ 0.17 Kg a. i/ha (PE) (T₃) yielded the highest seed production (1574 kg/ha), which was comparable to quizalofop-p-ethyl 100 g A.I/ha at 25 DAS (T₆) (1525 kg/ha). The weed-free treatment (T₉) outperformed all other treatments in terms of seed yield (1788 kg ha^-1). Parthenium hysterophorus, Medicago denticulate, Chenopodium album, Cynodon dactylon, and Echinochloa colonum founds associated with chickpea during experimental period. Amongst herbicides oxyflourfen recorded (5) weed count, (5) dry matter of weed at harvest. Weedy check recorded (37) weed count and (54) weed dry matter. At harvest highest The effectiveness of weed control was noted (90.74) in (T₃) oxyfluorfen (23.5% EC) @ 0.17 Kg A.I/ ha (PE) followed by (T₈) hand weeding at 30 DAS & hoeing at 45 DAS (79.62) and lowest weed control efficiency recorded in (T₇) imazethapyr (10% S. L) @ 0.75 Kg A.I / ha at 21 DAS (PoE) (58.64%). Then, treatment oxyfluorfen (23.5% EC) @ 0.17 Kg A.I/ ha (PE) (T₃) (11.96%) recorded lowest and (T₁₀) weedy check (49.04%) recorded highest weed index, respectively.
