Abstract
In order to evaluate the effects of type of herbicide and tillage implements on weeds control, seed yield and some agronomic traits ofbean (Phaseolous vulgaris L.), two field experiments were carried out as factorial arrangement in complete block design with three replications during 2007 and 2008 growing seasons at Khomain Research Station (49º 57´ N; 33º 39´ E, and 1930 m above sea level) in Agricultural and Natural Resources Research Center of Markazi Province. Two types of herbicides including Trifluralin and Ethalfluralin and three tillage implements such as rotary plow, disc and cultivator, comprised the experimental factors. Results of combined analysis showed that the effect of tillage implements and type of herbicide for seed yield and weed population were significant at 5% probability. In this research, application of Ethalfluralin and rotary plow had superiority for enhancement of seed yield and decrement of weeds population. In addition, tillage implements such as rotary plow and disc showed superiority for incorporation of soil and herbicide, respectively.
