A field experiment on economic feasibility of weed management practices in fenugreek was conducted during
rabi season of 2007-08 and 2008-09 at National Research Centre on Seed Spices, Ajmer (Rajasthan) for finding
suitable method of weed control. The experiment was laid in randomised block design with three replications.
Results revealed that besides weed free treatment significantly higher plant height, number of branches per
plant, number of nodules per plant, dry weight of nodules per plant and dry matter accumulation per plant at
(60 DAS, 90 DAS and at harvest) were recorded with the pre-emergence application of oxadiargyl @ 75 g/ha +
1 hand weeding at 45 days after sowing (DAS) but pre-emergence application of pendimethalin @ 1 kg/ha + 1
hand weeding at 45 DAS was at par with it. Similarly, yield attributes like number of pods per plant, length of pod,
pod weight, number of seeds per pod and test weight as well as seed and straw yields of fenugreek were higher
with pre-emergence (PE) application of oxadiargyl @ 75 g/ha + 1 hand weeding at 45 DAS. Besides weed-free
treatment, the lowest dry weight of weed at harvest, weed index and the highest weed control efficiency was
obtained under pre-emergence application of oxadiargyl @ 75 g/ha + 1 hand weeding at 45 DAS. The highest gross
and net returns were obtained in weed free treatment followed by pre-emergence application of oxadiargyl @ 75
g /ha + 1 hand weeding at 45 days after sowing but highest B : C ratio (4.38) was recorded with pre-emergence
application of oxadiargyl @ 75 g/ha + 1 hand weeding at 45 DAS.
