Effect of fertility levels and weeds management practices on weeds dynamics, yield and economics of wheat (Triticum aestivum L.)

Abstract

A field experiment was conducted during winter season of 2010-11 and 2011-12 at Research farm College of Agriculture, Gwalior. The result revealed that unchecked weed growth caused 40.16% reduction in grain yield of wheat. Amongst herbicides, application of pinoxaden + carfentrzone-ethyl recorded lowest population of weeds and weeds dry weight and gave highest grain (4889 kg/ha) and straw yield with maximum net return and B: C ratio. Maximum grain yield was obtained with weed free (4927 kg/ha).
