Abstract

An experiment was conducted under All India Network Research Project on Onion and Garlic, operating at the College of Horticulture, Orissa University of Agriculture and Technology, Sambalpur, Odisha during Rabi, 2010–11 to compare the efficacy of different weed control methods in onion. The experiment was laid out in a randomized block design with eight combinations of weed management practices and replicated thrice. Results revealed that significantly highest marketable bulb yield (19.19 t/ha) and total bulb yield (22.80 t/ha) was obtained with a higher percentage ‘A’ grade bulb (34.04 %) and an average bulb weight (69.83 g) by the application of oxyfluorfen before planting + one hand weeding at 45 days after transplanting. The identical weed management practice recorded highest 66.09% of weed control efficiency along with the lowest number of monocot weeds (26.33/m2), minimum fresh weight of weeds (40.08 g/m2) and minimum dry weight of weeds (14 g/m2). Imposition of manual hand weeding at 45 DAT facilitates a weed-free situation to the crop. Hence, it was concluded that maximum bulb yield can be obtained with the application of oxyfluorfen before planting + one hand weeding at 45 DAT due to the influence of oxyfluorfen and one manual hand weeding on monocot weeds during the crop growth period.
