Weed management is a critical factor influencing returns yield and economic returns of dill (Anethum graveolens L.). A field experiment was conducted during the rabi seasons of 2020-2021 and 2021-2022 at MPUA&T, Udaipur, Rajasthan, to evaluate the efficacy of various weed control strategies in dill cultivation. The study, laid out in a randomized block design with three replications, comprised thirteen weed control treatments, including pre and post emergence herbicides and integrated approaches. The application of oxadiargyl at 75 g/ha as a pre-emergence herbicide, followed by hand weeding at 40 days after sowing (DAS), resulted in the highest weed control efficiency (96.42% at 60 DAS) and significantly reduced weed density and biomass. This treatment improved growth attributes such as plant height, dry matter accumulation, and branches per plant, leading to a 61.58% increase in seed yield (7.66 q/ha) compared to the weedy check (4.74 q/ha). Economic analysis revealed that this integrated approach provided the highest net return (USD 770.59/ha) and benefit-cost ratio (1.93), making it the most effective and profitable weed management strategy for dill cultivation.
杂草管理是影响莳萝（Anethum graveolens L.）产量和经济效益的关键因素。2020 - 2021年和2021 - 2022年冬季，在拉贾斯坦邦乌代布尔的MPUA&T进行了一项田间试验，以评估莳萝种植中各种杂草控制策略的效果。该研究采用随机区组设计，重复三次，包括13种杂草控制处理，涵盖苗前和苗后除草剂以及综合方法。以75克/公顷的恶嗪草酮作为苗前除草剂，然后在播种后40天（DAS）进行人工除草，除草效率最高（60 DAS时为96.42%），显著降低了杂草密度和生物量。该处理改善了株高、干物质积累和单株分枝数等生长特性，与杂草对照（4.74公担/公顷）相比，种子产量提高了61.58%（7.66公担/公顷）。经济分析表明，这种综合方法提供了最高的净收益（770.59美元/公顷）和效益成本比（1.93），使其成为莳萝种植最有效和最盈利的杂草管理策略。
