Investigating of Integrated Weed Management in Broomcorn (Sorghum bicolor) Farms in Miyaneh Region

Abstract

The experiment was carried out as randomized complete block design in factorial with three replications to evaluate of the possibility of integrated weed management in Broomcorn (Sorghum bicolor) yield. Treatments were included herbicides (Foramsulfuron, Bromoxynil+MCPA and 2,4-D+ MCPA), application dose (recommendation dose, 25% less and more than recommended doses for corn farms) and mechanical control (with or without cultivation). The result indicated all factors including herbicides, application doses and cultivation were significantly influenced weeds density and dry weight. The best herbicide in weeds density and dry weight decreasing percentage was Foramsulfuron treatment. Cultivation treatment was significantly influenced weeds control. The best doses were 25% more recommended dose and recommended dose on weeds density and dry weight decreasing percentage.
