| Two field experiments were carried out at Shandaweel Agricultural Research Station (latitude of 26 33° N and longitude of 31 41°E), Sohag Governorate, Egypt in 2023/2024 and 2024/2025 seasons to study the effect of some integrated weed control treatments, rows pacing (80, 100 and 120 cm) and some treatments; Hoeing, Unweeded, Stomp, Dinamic, Steler star and Lumax herbicides on quality and yield of sugarcane G.2004-27 variety (Giza-4). A randomized complete block designs in a split-plot arrangement with three replications was used. Results revealed that growing sugarcane in rows spaced at 80-cm apart resulted in a significant increase in, number of millable canes/fed, stalk diameter and stalk fresh weight were produced by 120-cm. Row spacing 100-cm increased stalk height, brix%, sucrose%, purity%, sugar recovery%, cane and sugar yields/fed. The applied herbicides and hoeing (twice) negatively and significantly affected dry weight of both grassy and broad-leaved weeds and their total weight, compared to un-weeded plots. The applied herbicides and hoeing appreciably increased growth attributes, juice quality, cane and sugar yields/fed. Dinamic herbicide (pre-emergence) and/or hoeing were the most effective in weed eradication, resulting in higher sugarcane traits, compared with the other treatments. The effects of interactions among the studied factors on sugarcane and/or weed traits were discussed. Under conditions of the present study, growing sugarcane, in rows spaced at 100-cm and controlling accompanied weeds by Dinamic herbicide (750 g/fed) pre-emergence and/or hoeing twice, can be recommended for getting the highest cane and sugar yields/fed and highest values of net income and profitability%. | ||||
