Abstract:
The current study, titled "Studies on Bioefficacy of Different Herbicides for Weed Management in Chickpea [Cicer arietinum L.]". Ten treatments were applied in the field experiment, which the setup using a randomised block design. Among herbicides, oxyfluorfen had the tallest 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 (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), Oxyflourfen (T₃), and quizalofop-p-ethyl (T₆). The herbicide oxyfluorfen (T₃) yielded the highest seed production (1574 kg/ha), that was comparable to quizalofop-p-ethyl (T₆) (1525 kg/ha). The weed-free treatment (T₉) outperformed all other treatments in terms of seed yield (1788 kg ha^-1). During the experimental period, the chickpea was found to be associated with Parthenium hysterophorus, Medicago denticulate, Chenopodium album, Cynodon dactylon, and Echinochloa colonum. Oxyflourfen a type of herbicide, recorded a (5) weed count and (5) dry matter of weed at harvest. In the weedy check, there were 37 weeds counted and 54 weeds with dry matter. At harvest, oxyfluorfen (T₃) recorded the highest weed control efficiency (90.74), proceeded by (T₈) hand weeding at 30 DAS and hoeing at 45 DAS (79.62), and (T₇) imazethapyr (58.64%). Next, the oxyfluorfen treatment (T₃) (11.96%) and the weedy check (T₁₀) (49.04%) recorded the lowest and highest weed indices, respectively.
