Abstract:

A field experiment was conducted during 2016 and 2017 at the Regional Centre of Indian Council of Agricultural Research-Central Tuber Crops Research Institute, Bhubaneswar, Odisha to study the effect of climate on weed management practices in elephant foot yam [Amorphophallus paeoniifolius (Dennst.) Nicolson]. Higher average monthly maximum temperature was noticed during early crop growth period (vegetative phase) in 2017 compared to 2016. The mean minimum temperature was higher during the cropping period of 2017 compared to 2016. During 2017, Celosia argentea was observed more number and grown more vigourously compared to 2016. The weed biomass was higher during the year 2017 compared to 2016 in all weed management treatments. Higher average monthly maximum and minimum temperatures during early crop growth period (vegetative phase) favoured for more number of weeds to grow vigourously during 2017. The effect of weather was noticed more in pre (1 DAP) and post emergence (45 DAP) herbicide application treatments and weedy check. During 2016 recorded higher corm yield than 2017 irrespective of weed management practices. The weedy check treatment resulted in lower corm yield in 2017 than 2016. It can be concluded that higher rainfall and average monthly maximum temperature during crop growing period led to lower herbicide efficacy or weed management efficiency under high rainfall sub-humid zone.
