A field experiment was conducted during Rabi season of 2011-12 at Junagadh (Gujarat) to find out most effective and economical method of weed control in Rabi fennel (Foeniculum vulgare). Results revealed that besides weed free treatment, significantly higher plant height, seed and stover yields of fennel were recorded with pre-emergence application of pendimethalin at 0.90 kg/ha + post-emergence application of fenoxaprop-ethyl at 75 g/ha at 45 DAS, which was at par with pendimethalin at 0.90 kg/ha PRE + hand weeding (HW) at 45 DAS and HW twice at 15 and 45 DAS. These treatments also recorded lower weed density and dry weight of weeds along with higher net returns and B:C ratio owing to lower weed index and higher weed control efficiency. The highest depletion of weed seed bank was observed with pendimethalin at 0.90 kg/ha PRE + HW at 45 DAS.
