Evaluation of the Effect of Additive Intercropping of Phaseolus vulgaris in Weed Control at the Maize Field and its Effects on Yield and Land Use Efficiency

Reduction of herbicide consumption is one of the goals of modern agriculture. Intercropping is an option to reduce growth and reproductive potential of weeds while maintaining agricultural system productivity. The objective of this study was to evaluate the effects of bean and maize intercropping on weed control, economical yield of system and land use efficiency. Experiment was done at the Research Station of Bu – Ali Sina University in 2010 growing season. A completely randomized block design with three replications was used. MWI, MWF, MP6, MP12 and MP18 were submitted to the five treatments: no weeding, weeding, and additive intercropping of 6, 12 and 18 plant of bean with pure stand of maize. The effects of experimental treatments were significant (p
