A field experiments was conducted at Professor Jayashankar Telangana State Agricultural University, Rajendranagar during kharif 2017 for the evaluation of dosage of diuron suitable in both red and black soils. The treatment consisted of test herbicides such as, diuron 80% WP at 0.5 kg ha-1, 0.75 kg ha-1 and 1.0 kg ha-1 along with registered formulation of pendimethalin 38.7% CS at 677 g ha-1, intercropping with green manure crop, mechanical weeding thrice at 20, 40, 60 DAS and unweeded control. The experiment was laid out in a randomised block design replicated thrice. The weed flora of the experimental field in red soil was dominated by Cynodon dactylon, Rottboellia exaltata, Parthenium hysterophorus, Trianthema portulacastrum, and Commelina benghalensis. While in case of black soil predominant flora was Cynodon dactylon, Cyperus rotundus, Parthenium hysterophorus, Euphorbia geniculata, Tridax procumbens, Cyanotis cristata, Digera arvensis and Celosia argentia. The treatments, mechanical weeding thrice at 20, 40 and 60 DAS, polymulch treatments reduced the weed growth in both red and black soils. Among the herbicides, diuron at 1.0 kg ha-1 fb pyrithiobac sodium + quizalofop p ethyl in red soil and both diuron at 1.0 kg ha-1 and 0.75 kg ha-1 along with sequential application of herbicides reduced the weed count and also the weed dry matter. The kapas and stalk yields were higher with polymulch, mechanical thrice at 20, 40, 60 DAS, while among the herbicides 1.0 kg ha-1 in red soil and 0.75 kg ha-1 in black soil.
