Chemical control of complex weed flora for achieving higher productivity in wheat (Triticum aestivum L.)

Abstract

A field experiments was conducted during winter seasons of 2020 and 2021 at Shree Durga Ji Post Graduate College, Chandeshwar, Azamgarh, U.P. to study the effect of herbicides on wheat and associated weeds. Five weed species were common infesting wheat fields were Phalaris minor, Chenopodium album, Anagallis arvensis, Parthenium hysterophorus and Cyperus rotundus. Among the herbicidal treatments, post-emergence application of carfentrazone ethyl at 0.025 kg a i/ha performed significantly with respect to reduction in density of weeds ultimately enhanced the production of biological yield of wheat.
