Abstract:

Several species of Amaranthus are known to be important weeds that reduce crop yield. For stepwise regression analysis of sugar beet (beta vulgaris) traits an experiment was performed with factors of weed densities and planting patterns. In emergence and presence of 12 weed plants per meter row of sugar beet, sodium content in crop roots extract was 3.03%, but only 1.62% from weed free plots. Planting pattern of Zigzag may increase nitrogen content of sugar beet roots significantly. In lower weedy plots syrup purity in roots improved significantly. The alcality value in weed free plots and also in plots with 4 weed plants per meter row of sugar beet was higher than 2. The lower purity was also devoted to 12 redroot pigweed plants per meter row of sugar beet. Mean comparisons indicated that planting pattern of Zigzag could increase molasse sugar concentration of sugar beet roots significantly up to 2.44%, and Zigzag pattern experienced 12.7% reduction in molasse sugar compared to linear pattern. The stepwise regression analysis verified that the percentage of sodium and nitrogen in root, and molasse sugar content had a marked increasing effect on the root yield of sugar beet.
