To evaluate integrated weed management on yield and weed biomass of bean an experiment were conducted as a split plot based on randomized complete block design with three replications at the Research Station of Agriculture in Damavand in 2014.Main plot of the mechanical control (Cultivation)levels including the application and no application of cultivator and sub-plots chemical control levels including hand weeding(control), mixing 100% of the recommended Pursuit(Pursuit, BASF, Germany- SL 10%) and reminder pendimetalin(Stomp, BASF, Grmany- EC 33% ), blending 50% of the recommended Pursuit and reminder pendimetalin, 100% of the recommended pendimetalin, 100% of the recommended Pursuit, 50% and 50% of the recommended daily amount recommended pendimetalin were Pursuit. The results showed that the mechanical control and chemical control effect were significant for all traits. The results showed that application of Cultivation with the incorporation of 50% and a reminder pendimetalin and Pursuit recommended amount for most showed the best results. The results showed that the effect of the mechanical control factor on plant height, chlorophyll b, weed dry weight and grain yield was statistically significant. The effect of chemical control factor on the chlorophyll a, chlorophyll b, yield and dry weight of weeds was statistically significant. The first factor in second factor interaction on grain yield, chlorophyll a and chlorophyll b was statistically significant.
