Abstract:
The present study was carried out during Rabi, 2019 to study the various weed management in fennel (Foeniculum vulgare Mill.) at Kittur Rani Channamma College of Horticulture, Arabhavi. Results revealed that, the highest plant height (172.20 cm), number of branches (23.56/plant), plant spread (63.36 cm), number of umbels (32.34/plant), number of umbellates (24.22/umbel), seed yield (2205.53 kg/ha), straw yield (6100.24 kg/ha) and harvest index (36.15%) of fennel were recorded with hand weeded plot which was on par effect with pre-emergent application of pendimethalin 30% EC + post-emergent application of quizalopfop-ethyl 5% EC. The lowest number of weeds and weed index at harvest (8.26/m² and 10.91%) recorded in pre-emergent application of pendimethalin 30% EC + post-emergent application of quizalopfop-ethyl 5% EC. Highest cost of cultivation (₹1,28,189.94 /ha) and gross returns (₹2,20,553 /ha) was obtained in hand weeding plot. B:C ratio of 1.74 was found in pre-emergent application of pendimethalin 30 EC + post-emergent application of quizalopfop-ethyl 5% EC. Hence, effective management of weeds along with better growth, yield attributes and profitable production in rabi fennel can be obtained by pre-emergent application of pendimethalin 30% EC + post-emergent application of quizalopfop-ethyl 5% EC.
