Abstract: Efficacy of two weedicides at recommended rate i.e., pendimethalin (liter ha -1) and oxadiazon (0.8 liter ha -1) was tested and compared with weed free (manual hoeing) and weedy control. Single application of any of above weedicide was not sufficient to obtain yield equal to weed free treatment. Application of pendimethalin and oxadiazon were effective in controlling weeds initially for 80-90 days. Highest bulb yield (10 ha -1) was found in weed free treatment followed by oxadiazon (5.293 ha -1), pendimethalin (4.043 ha -1). Lowest bulb yield was found in weedy control.
