Abstract:
A field experiment was conducted at Agronomy Farm, College of Agriculture, Nagpur during rabi season of 2020-21 to evaluate the effect of different combinations of herbicides on weed control and growth of wheat (Triticum aestivum L.) on clayey and slightly alkaline soil. The experiment was laid out in randomized block design with ten treatments replicated thrice. Fourteen weed species, viz. Cynodon dactylon, Cyperus rotundus, Dinebra arabica, Eragrosis major, Commelia benghalensis, Corchorus aestuans, Chenopodium album, Digera arvensis, Convolvulus arvensis, Celosia argentea, Euphorbia hirta, Euphorbia geniculate, Amaranthus viridis and Parthenium hysterophorus infested the wheat field. Results reveal that among all herbicidal treatments, post emergence application of clodinafop propargyl + metsulfuron methyl @ 0.06 + 0.004 kg a.i. ha^-1 at 35 DAS was found to be the most effective in controlling both monocot and dicot weed population and better height of plant (97.30 cm), number of tillers m^-1 row length (154.13) and dry matter plant^-1 (12.65 g) of wheat crop across the crop growth period which resulted in maximum weed control efficiency (88.67%) and lowest weed index (3.76%) followed by post emergence application of sulfosulfuron + metsulfuron methyl @ 0.03 +0.002 kg a.i. ha^-1 at 35 DAS.
