| Abstract | ||
| A field experiments were conducted at Agric. Res. St. (latitude of 26.33° N and longitude of 31.41° E), Sohag Governorate, Egypt during 2020/2021 and 2021/2022 seasons to find out the optimal of seeds rates (1.0, 1.5 and 2.0 drills) and harvest ages (10, 11 and 12 months) for yield and quality of three sugarcane varieties (G.T.54-9, G.2003-47 and G.2004-27). A split-split plot arrangement with three replication was used. The main-plots were devoted for harvest ages, seed rates in sub plots, while, sugarcane varieties was distributed in the sub-sub plots, in both seasons. Delaying the harvest age from 10 to 12 resulted in a significant increase in millable stalk height, diameter, number of millable canes/fed, cane and sugar yields/fed, along with brix, sucrose, and sugar recovery%, in both seasons. The results revealed that, planting sugarcane using 2.0 drills improved height, number of millable canes/fed, cane and sugar yields/fed. While, planting by using 1.0 drill improvised millable stalk diameter and quality characteristics in both seasons. Sugarcane varieties G.T.54-9 and/or G.2004-27 superiority in cane yield and millable stalk height and diameter. While, G.2003-47 variety was superior in quality characteristics and sugar yield/fed. However, G.2004-27 variety attained the more number of millable canes/fed, in both seasons. Under conditions of this work, it is recommended to cultivate these sugarcane varieties by rates of 2.0 drills and harvest age to 12 months to achieve a high cane and sugar yields/fed. | ||
