Abstract

The current study was conducted at El-Mattana Agriculture Research Station, Luxor Governorate, Egypt, in 2021/2022 and 2022/2023 (two plant-cane). In order to examine the effects of various irrigation levels and integrated weed control managements, as well as their interactions, on weed growth, water use efficiency and quality traits of sugarcane. The lowest dry weight of weeds when the irrigation level was 60% while the greatest value was recorded in the first and second seasons when the irrigation level was 100%. The results demonstrated that the irrigation levels, weed control treatments and their interactions were significant influences on dry weight of weeds at 105 days (grassy, broad-leaved and total weeds) in both seasons. The third level of irrigation (I3), Hoeing thrice (T11) and their interaction gave the lowest dry weight of grassy, broad-leaved and total weeds but the first irrigation (I1), un-weeded (T12) and their interaction had the maximum dry weight one in both seasons.  For sugarcane traits, all quality traits were insignificantly affected by irrigation levels, weed control treatments and their interactions except sugar yield and seasonal water consumptive use under irrigation levels and percentage of brix and sucrose under weed control treatments in the two seasons. The first irrigation level (I1), Hoeing thrice (T11) and their interaction gave the highest values for most traits under study in the first and second seasons.
