A field experiment was conducted at the Horticultural Research Station Mondouri, BCKV(Agricultural University), India during 2013-14 and 2014-15 to study the effect of weed control methods on weed population dynamics as well as their effects on yield and quality in garlic. The treatment combinations used were oxyfluorfen 23.5% ec (goal) applied before sowing and at 60 days after sowing (das), pendimethalin 30% ec (stomp) applied before sowing and at 60 das, quizalofop ethyl 5% (terga super) applied before sowing and at 60 das, oxyfluorfen 23.5% ec applied before sowing + one hand weeding (hw) at 45 das, pendimethalin 30% ec applied before sowing + one hw at 45 das, quizalofop ethyl 5% applied before sowing + one hw at 45 das, combined spray of quizalofop ethyl 5% and oxyfluorfen 23.5% ec at the time of sowing and at 60 das, combined spray of pendimethalin 30% ec and quizalofop ethyl 5% at the time of sowing and at 60 DAS, weedy check (control). Garlic yield in all the treatments were significantly increased except in control. The maximum weed control efficiency, highest bulb yield, TSS, Vit C, RSA and minimum weight loss during storage (g) were found with pendimethalin 30% EC (Stomp) applied before sowing + one hand weeding at 45 days after sowing was found to be the best treatment as compared to control and other herbicides. Weed reduced the bulb yield by 56 per cent over the best treatment. A gradual loss of weight was observed in garlic cloves. Curing and harvesting at the correct time is very much essential for successful long term storage.
