Determination of important parameters for weed control in intensive apple orchards: weed species and its density

Abstract: Weed control especially in the tree strips cost high values in intensive apple orchards. Determination of important parameters such as weed biomass, the quantity and quality of yields for weed control is important for orchard profitability. In this study weed species, their densities and weed biomass in intensive Golden Delicious’/M 9 orchard were determined. 18 weed species belonging to 11 families were determined and they were generally perennial. Total dried biomass was calculated 910.9 g/m². While field bindweed had the highest weed density value, curly dock had the highest dried weed biomass value (228.6 g/m²).
