Abstract: 

IN ORDER TO STUDY THE EFFECTS OF WEEDS WHICH COMPETE WITH MELON CROP IN ASSOCIATION WITH OTHER MEMBERS OF A NATURAL OCCURRING COMMUNITY, ON MELON GROWTH, YIELD AND QUALITY, THE PRESENT INVESTIGATION WAS CARRIED OUT IN MASHAD-IRAN, DURING 2007. THIRTY FIVE PLOTS WERE SELECTED RANDOMLY IN A 9×9 M GIRDED MELON CULTIVATED FILED. WEEDS WERE ALLOWED TO COMPETE FREELY WITH MELON BY THE HARVEST TIME IN 32 PLOTS. THE OTHER 3 PLOTS WERE WEEDED DURING CROP DEVELOPMENT. WEED SAMPLING WAS CONDUCTED PRIOR TO MELON HARVESTING. DENSITY, FREQUENCY AND DRY MATER WERE RECORDED SPECIES-WISE. MAXIMUM MELON PLANT GROWTH, FRUIT YIELD AND ITS QUALITY CHRACTERISTICS WERE ALSO RECORDED. REGRESSION EQUATIONS WERE ESTABLISHED TO DETERMINE THE COMPETITIVE RELATION BETWEEN POPULATION AND DRY MATTER OF EACH WEED SPECIES AND MELON CHARACTERISTICS. RESULTS REVEALED THAT DRY MATTER HAD MORE SIGNIFICANT RELATION WITH CHARACTERISTICS UNDER STUDY COMPARE TO WEED DENSITY. WEEDS SHOWED TWO ADVERSE COMPETITIVE RESPONSES. ACCORDING TO THEIR EFFECTS ON MELON TRAITS, WEEDS WERE DIVIDED IN ANTAGONISTIC AND SYNERGISTIC GROUPS. RESULTS SHOWED THAT YIELD WAS MORE AFFECTED BY WEEDS THAN QUQLITY CHRACTERISTICS.
