Abstract: A field experiment at Junagadh Agricultural University, 12 treatments for weed management in Fenugreek were tested.Apart from the weed-free control, treatments significantly boosted growth parameters like plant height, branches per plant, and flowering time.They also improved yield metrics including pod number, length, weight, seed count, test weight, seed, straw, biological yield, and harvest index.These positive outcomes were recorded with the treatment sequence involving one hand weeding (HW) at 15 days after sowing (DAS) followed by a tank mix of Quizalofop ethyl 0.020 kg ha-1 + Metribuzin 0.075 kg ha-1 applied as post-emergence, then another HW at 30 DAS, and finally, one HW at 10 DAS followed by Quizalofop ethyl 0.040 kg ha-1 (PoE) at 30 DAS.Apart from the weed-free condition, the sequence involving 1 HW at 15 DAS followed by a tank mix of Quizalofop ethyl 0.020 kg ha-1 + Metribuzin 0.075 kg ha-1 as post-emergence, further HW at 30 DAS, and 1 HW at 10 DAS followed by Quizalofop ethyl 0.040 kg ha-1 (PoE) at 30 DAS demonstrated effectiveness in reducing weed population until harvest.It resulted in lower dry weight of weeds, reduced weed index, and higher levels of weed control efficiency and herbicidal efficiency index.The treatment sequence that involved 1 HW at 15 DAS followed by a tank mix of Quizalofop ethyl 0.020 kg ha-1 + Metribuzin 0.075 kg ha-1 as post-emergence, subsequent HW at 30 DAS, led to the highest net return of 67723 ha-1.Following closely were the weed-free treatment and 1 HW at 10 DAS followed by Quizalofop ethyl 0.040 kg ha-1 (PoE) at 30 DAS.However, the treatment that showed the highest Benefit-Cost Ratio (BCR) of 3.50 was the one involving 1 HW at 15 DAS followed by a tank mix of Quizalofop ethyl 0.020 kg ha-1 + Metribuzin 0.075 kg ha-1 as post-emergence, and subsequent HW at 30 DAS.
