Growth and yield of Kharif black gram (Phaseolus mungo L.) as influenced by pre and post emergence of herbicide

Abstract

A Field experiment was carried out at the experimental site of Bihar Agricultural College Farm, Bihar Agricultural University, Sabour during kharif season, 2018, to study the effect of pre and post emergence herbicide on growth and yield of Blackgram [Phaseolus mungo L.) Among herbicide weed treatments, the highest growth and yield parameters were obtained in intercultural operation at 20 & 40 DAS and it was statistically at par with Pendimethalin (PE) fb Imazethapyr (POE) and Oxyfluorfen (PE) fb Imazethapyr (POE). All chemical treatments increased the growth, seed yield and yield attributes as compared to weedy check. Weedy check registered with lowest seed yield and yield attributing characters.
