Abstract:
In order to investigate the integrated weed management on broomcorn farms, a field experiment was conducted of 2010 in Qazvin region. The experimental design was randomized complete block with 24 treatments and 4 replications. Treatments included different planting patterns whit three levels, including planting a row, double row (planting square) and (planting zigzag) and herbicide use on two levels, including nicosulfuron and foramsulfuron and dose of herbicides in four levels, including 1, 1/5, 2 and 2/5 liters per hectare. Three samples of weeds after treatments were applied based on the percentage of control density and weed dry weight by comparison with control per plot was calculated. The results showed that among the different patterns of planting, planting density and the zigzag had the greatest loss of weed dry weight. foramsulfuron herbicide was better than nicosulfuron to control of weeds. Between the doses treatments, used 2/5 litter herbicide dose per hectare had the greatest reduction weed dry weight. And used 1 litter herbicide dose per hectare had the least reduction weed dry weight.
