Abstract

A field experiment was conducted to determine the effect of various corn and bean intercropping densities on weed population in Agricultural Research Station Ferdowsi University of Mashhad. The experimental Treatments were included: corn intercropping with bean at the common density of bean plus 10%, 20% and 30% increased in bean density, bean intercropping with corn at the common density of corn plus 10%, 20% and 30% increased in corn density and control treatments (sole crops of corn and bean). This experiment was conducted in a low input production system. The results indicated that intercropping treatments lead to reduction of weed effect when compared with sole cropping. Increasing in crop plant density lead to reduction of WEED BIOMASS. The highest and the lowest weed dry weight was resulted from the sole corn treatment (29.17 g m-2) and the bean intercropping with corn at the common density of corn plus 30% treatment (4.97 g m-2), respectively. Corn and bean Intercropping had significant effects on yield. The highest and the lowest bean biological and ECONOMICAL YIELD were obtained from the sole cropping of bean with 5.3 and 1.6 ton/ha and bean intercropping with corn at the common density of bean plus 30% with 2.7 and 0.7 ton/ha, respectively. The highest corn biological and ECONOMICAL YIELD were obtained in the sole cropping of corn with 14.7 and 7.3 ton/ha, respectively. The highest (1.56) and the lowest (0.77) land equivalent ratio also was obtained from the intercropping of corn with common density of bean plus 10% treatment and from the intercropping of bean with corn at common density of corn plus 30% treatment, respectively.
