Abstract:

Wheat is one of the most important food crops of the world. However, its production and productivity has been limited due to various abiotic and biotic factors including weeds. The aim of this study was to investigate the effects of post emergence broad leaf herbicides application on management of weeds and increasing productivity of wheat. Treatments consisted of three post emergence broadleaf herbicides; Weedban 40 % WDG @ 75g/ha, Agro 2,4-D 720 g/L @ 1L ha-1, Pallas 45 OD @ 0.5L ha-1 along with weed free and a weedy check that were laid out in RCBD with three replications. The field was infested with eight weed species in which six species were annual broadleaf weeds and two species were annual grasses. The tallest plants were recorded from weedy check plots while shortest plants were recorded at Agro 2, 4-D amine salt 720g/l. Results also showed all traits were significantly affected by application of different weed control treatments. There was no dry weed biomass at weed free plots and also the highest weed control efficiency (99.89%) was recorded from application of weed free while no weed control at weedy check. Maximum stand count and thousand grain weight recorded from application Pallas 45 OD and weed free while lowest values were obtained at weedy check. The maximum numbers of tillers per plant were recorded at all treatments other than Agro 2, 4-D 720g/l and weedy check. Moreover, the maximum number of spike length (9.25cm), seeds per spike (72.33), thousand grain weight (47.00g), grain yield (4873.30kg/ha) were recorded from Weed ban 40% WDG while the lowest values were observed from the weedy check. Therefore, it can be concluded that application of Weedban 40% WDG effectively managed weeds and gave better grain yield which could be recommended for the test environment.
