Abstract:
An experiment was conducted to find out practically convenient and economically feasible weed management practice in onion at the Horticulture Research Farm, R.A.K College of Agriculture, Sehore (M.P). The experiment comprised of ten treatments of pre-emergence herbicides with hand weeding and unweeded control. The experiment was laid out in randomized block design with three replications. Hand weeding treatment (three hand weeding at 25, 50, and 75 DAT) recorded significantly the lowest dry matter of weeds and the highest weed control efficiency. All the growth and yield attributes of onion viz., plant height (64.93 cm),leaves width (1.51 cm), no. of leaves (8.67), neck thickness (1.11 cm), fresh bulb weight (70 g),polar diameter (5.48 cm),equatorial diameter of bulb (6.34 cm) and bulb yield (545.75 q ha-1) were recorded maximum in hand weeding plots. The highest cost: benefit ratio was found with T₁₀ (Oxyfluorfen 23.5% EC @ 1.25kg a.i. /ha (PE) (1:6.88) followed by T₉ (Oxyfluorfen 23.5% EC @ 1kg a.i./ha (PE) (1:6.78).
