A Field experiments was conducted during Rabi seasons of 2008-09 and 2009-10 to study the effect of integrated weed management
practices on yield and yield attributes of fenugreek (Trigonella foenum graecum L.). Results revealed that two hand weedings at 25 and 45 days
after sowing (DAS) recorded minimum dry matter yield of weeds, maximum weed control efficiency (94.5 %). Among the herbicides, preemergence
application of pendimethaline @ 0.5 kg ai/ha + 1 hand weeding at 35DAS was most effective in reducing dry matter yield of weeds.
It had positive effect on yield attributes which resulted into significantly higher seed (1573 kg/ha) and straw yield (4587 kg/ha), which were
statistically at par with yields obtained under two hand weeding. The improvement in seed yield (41.20%) and additional returns by Rs. 5076 per
hectare due to pre-emergence application of pendimethaline @ 0.5 kg ai/ha + 1 hand weeding at 35 DAS over weedy check.
