| Abstract | ||
| Two field experiments were conducted at Shandaweel Agric. Res. St. (latitude of 26.33° N and longitude of 31.41° E), Sohag Governorate, Egypt in 2017/2018 and 2018/2019 seasons to assess the yield and quality of the new sugarcane varieties viz. (G.2003-47 and G.2004-27) and G.2005-47 promising genotype, compared to the commercial variety GT.54-9 as affected by three seed rates (1.0, 1.5 and 2.0 drills of three-budded cane cuttings). A split plot design was used. Planting sugarcane using 2.0 drills of cuttings improved most of the studied traits. Significant improvements in brix%, sucrose% and sugar recovery% (SR%) were recorded in case of growing using 1.0 drill, while using 1.5 drill resulted in the highest millable cane (MC) weight. The commercial GT.54-9 variety was superior in most of the studied traits. Variety G.2003-47 was superior in brix%, sucrose% and SR%, meanwhile, variety G.2004-27 attained the highest number of MC/fed. The interaction between the studied factors markedly affected all the studied traits, except MC height, in both seasons. Millable cane weight exhibited positive and high significant correlation with MC height and diameter. However, it was negative correlation between number of MC/fed with MC diameter, brix and sucrose%. Variety G.2004-27 showed broader adaptability for all studied seeding rates. Based upon the previous results, planting sugar cane variety GT.54-9 using 2.0 drills cutting seed setts could be recommended to attain the highest cane yield, while, planting variety G.2003-47 using 1.5 drill is recommended to get the maximum sugar yield under conditions of the present work. | ||
