Abstract:
The aim of this comparative study was evaluation of pre and post emergence herbicides Effect to control weeds in corn field. Experiment was conducted as a randomized complete block design with three replications. The treatments included: no weed control, weed, complete mechanical control, Nicosulfuron herbicides (two liters per hectare) as pre- and Erradican 4 liters per hectare as post emergence. Some properties were studied such as the dry weight of weed species, plant height, seed number on the cob, seed yield, 1000seed weight, biological yield. Totally, result showed that application of herbicide led to reduction of damages caused by weeds, also, it was determined that using of Nicosulfuron+ Erradican had highest effect on weed control in compare to Nicosulfuron or Erradicanaplication. application of Nicosulfuron, Erradican, Nicosulfuron+ Erradican and complete mechanical control showed 45, 38, 58 and 84% seed yield increasing in compare to no weed control.
