. Results revealed that widening spaces between rows of sugarcane from 80 up to 100 and 120 cm resulted in a significant and gradual increase in dry weight of narrow and broad leaved weeds as well as total weeds/m2 in both seasons. There was a significant influence of the applied weed treatments on dry weight/m2 of both narrow and broad-leaved weeds and total weeds/m2. The results showed that the most effective treatment in eliminating both narrow and broad-leaved weeds was hand hoeing three times, followed by the application of the used herbicides combined with one hand hoeing, and the application of each herbicide alone. Growing sugarcane in rows spaced at 80-cm apart resulted in a significant increase in stalk height, number of millable canes, cane and sugar yields/fed. The thickest cane stalks were produced from plants grown at 120 cm. Row spacing rows at 100 cm gave the highest values of brix, sucrose, juice purity and sugar recovery percentages. Practicing hand hoeing three times 25, 45 and 65 DAP to get rid of weeds associated with sugarcane plants resulted in the highest values of the studied traits, while the unweeded plots gave the lowest ones. Under the conditions of the present work, growing sugarcane, in rows spaced at 80 or 300 cm and controlling accompanied weeds by manual hoeing three times at 25, 45 and 65 DAP, Brominal + hand hoeing once and/or Garlon + hand hoeing once can be recommended for getting the highest cane and sugar yields/fed. Meanwhile, economic evaluation of the studied factors showed the planting sugarcane in rows of 80-cm apart as well as controlling weeds by applying Brominal herbicide hand hoeing once or manual hoeing three times gave the highest values of net income and profitability %.
