Abstract

Weeds are the most important biotic constraints to garlic production. Weed in garlic field are worldwide problem and losses due to weed were as high as 72.5%. The main problem for farmers in garlic cultivation is weed control, which occurs mainly during the vegetative growth stage of the crop. Since, labour availability to manual weeding and higher wages, it is necessary to have the strategy of conventional hand weeding and chemical control of weeds in appropriate time to attain target yield and economic benefit. In this view, field experiments were conducted at Fruit Research Station Intkhedi Bhopal, RAK College of Agriculture, Sehore (M.P.) during the Rabi season, 2017-18. The experiments were laid out in RBD and replicated thrice. The weed management options viz., pre and post emergence herbicide applications in different doses and time with conventional hand weeding. The trials were also compared with control plot (without hand weeding and without use of herbicides). Results indica

Conclusion

As a result, in this study it has been found that to achieve good bulb yield and yield quality, it is best to apply two hand weeding 30 and 60 DAS and in addition to treatment oxyfluorfen 23.5% EC 250 g a.i. hectare-1 (pre-emergence) + one hand weeding after 30 DAS and Oxadiargyl 80% WP 100 g a.i. hectare-1 (pre-emergence) + one hand weeding after 30 DAS can also achieve good bulb yield and yield quality as compared to other treatments. Intercultural activities in the soil make the soil brittle, allowing sufficient moisture and air to flow through it to aid plant growth. The crop also benefited from two hand weeding done at 30 and 60 days after sowing in the experiment. Therefore higher bulb yield and lesser weed infestation as well as maximum gross and net return were recorded by cultural practices and pre-emergence herbicides treatments. Thus appropriate choice for weed control in garlic would be an integration of cultural and herbicidal control combination for boosting the Garlic pr
