Effect of weed management on growth and yield of mungbean [Vigna radiata (L.) Wilczek]

Abstract

A field experiment entitled “Efficacy of herbicides on growth and yield of mungbean [Vigna radiata (L.) Wilczek]” was conducted at Agronomy Farm of Agricultural Research Station, Mandor, Jodhpur during kharif season, 2018. The experiment comprised of twelve weed control treatments that were laid out in randomized block design and replicated thrice. Results indicated that among herbicidal treatments, lowest weed density (No. m-2), dry matter (g m-2) recorded under the application of pendimethalin + imazethapyr (ready mix) 900 g ha‑1 as PE and it was at par with its ready mix at 800 g ha‑1. Application of imazethapyr 90 g ha-1 (PoE) and pendimethalin 750 g (PE) also observed significantly lower weed density and weed dry matter of weeds at 30 and 60 DAS compared to weedy check. Results further indicated that, weed free recorded highest seed yield and it was found at par with pendimethalin + imazethapyr (ready mix) 900 g ha‑1 as PE followed by pendimethalin + imazethapyr (ready mix) 800 g ha‑1.
