Sequential use of herbicides for weed control in Egyptian clover

摘要

To study the effect of sequential use of herbicides for weed control in Egyptian clover (berseein) crop, a field experiment was conducted under All India Coordinated Research Project on Forage Crops and Utilization, Mahatma Phule Krishi Vidyapeeth, Rahuri, Maharashtra, during Rabi (winter) seasons of 2012-2013, 2013-2014 and 2014-2015. The field experiment with 10 weed control treatments was laid out in a randomized block design with three replications. Among the weed control treatments, oxyfluorfen0.1 kg/ha fb imazethapyr 0.1 kg/ha applied after first cut recorded the lowest weed count and weed dry weight with higher weed control efficiency. However, it was at par with the application of imazethapyr 0.1 kg/ha after first and second cut. The greenforage yield, dry matter yield, seed yield, straw yield, crude protein yield, gross monetary returns and benefit-cost ratio were significantly superior in the treatment of imazethapyr 0.1 kg/ha applied after harvest of first and second cut.
