Abstract:
A field experiment was conducted during Rabi season of (2017-18) to study the impact of herbicides on weed control efficiency and yield attributes in Garlic (Allium sativum L.) at Fruit Research Station Intkhedi Bhopal, RAK College of Agriculture, Sehore (M.P.) The investigation was carried out to study the relative impact of cultural practices and herbicides on weed control in garlic production. The result of the present investigation indicated that, the population of monocot and dicot weeds recorded the least weed density (2.0, 3.0) in treatment two hand weeding at 30 and 60 days after sowing followed by application of Quizalofop ethyl 5% EC 40 g a.i. /ha+ one hand weeding (15.20) after 30 DAS and Oxyfluorfen 23.5% EC 250 g a.i. /ha + one hand weeding (18.12, 8.00) after 30 DAS at 30, 60 and 90 days after sowing. While the highest weed population density found in control plot (132, 125). The treatment two hand weeding at 30 and 60 DAS found maximum bulb yield (86.45) and thereafter it were received from Oxyfluorfen 23.5% EC 250 g a.i. ha^-1 + one hand weeding after 30 days after sowing (84.33) as compre to control (25.62). The B:C ratio in treatment Oxyfluorfen 23.5% EC 250 g a.i. ha^-1 + one hand weeding after 30 days after sowing (1:60) was recorded the highest net return of 469385 ₹ ha^-1 as compare to two hand weeding at 30 and 60 DAS which has net return of ₹ 447963 ha^-1. However, Control plot (without hand weeding and without use of herbicides) recorded significantly lesser B: C ratio (1.20).
