A field experiment was conducted at the HRS, Mondouri, Bidhan Chandra Krishi Viswavidylaya, Nadia from during 2013-14 and 2014-15, to study the effect of weed control methods on weed population dynamics, their effects on yield and quality in garlic (Single clove). The treatments were Oxyfluorfen 23.5% EC (Gola) applied before sowing and at 60 DAS, Pendimethalin 30% EC (Stomp) applied before sowing and at 60 DAS, Quizalofop Ethyl 5% 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 sowing and at 60 DAS, Combined spray of Pendimethalin 30% EC and Quizalofop Ethyl 5% at sowing and at 60 DAS, Weedy check (Control). The most predominant weed flora were Chenopodium album, Chenopodium murale, Convolvulus arvensis, Parthenium hysterophorus, Cyprus rotundus and Euphorbia hirta. For controlling weeds and maximum WCE%, highest bulb yield, high TSS, Vit C and antioxidant and minimum weight loss during storage (g)was found with Pendimethalin 30% EC applied before sowing + one HW at 45 DAS was found to be the best herbicides as compared to control and other herbicides. Weed reduced the garlic bulb yield by 46% over the best treatment Pendimethalin 30% EC applied before sowing + one HW at 45 DAS.
