Efficient weed management in groundnut (Arachis hypogaea) through appropriate herbicides

Abstract

A field experiment was conducted during 2017–18 and 2018–19 in kharif season at Instructional Farm of Krishi Vigyan Kendra, Chhatarpur to study the suitable herbicides for effective management of weed flora of groundnut crop. Randomized block design was used with 4 replications consisting of 7 treatments as detailed in methodology. The results showed that combination of two compatible herbicide molecules like Imazethapyr 100 g a.i./ha + Quizalofop @37.5 g a.i/ha were quite effective against dominated mixed weed flora in groundnut, resulting in higher WCE, WCI, yield and economic net return (93.63%, 93.57%, 16.2 q/ha and `44655/ha) fb use of Imazethapyr @100 g a.i./ha + Fenoxaprop @37.5 g a.i/ha (90.44%, 90.5% 15.2 q/ha and `39380/ha respectively) as compared to control plot. Therefore, above herbicides will be better alternative for suppressing weed flora in the groundnut crop than the sole herbicide.
