| Abstract | ||||
| Two field trails were carried out at El-Mattana Agricultural Research Station (latitude of 25.17o N and longitude of 32.33o E), Luxor Governorate, Upper Egypt during 2013/2014 (virgin cane) and 2014/2015 (first ratoon crop,) to find out the optimum harvesting age for some sugarcane varieties. Treatments consisted of a factorial combination of three promising sugarcane varieties (G.98-28, G. 99-160 and G.2003-49) and five harvesting age (10, 11, 12, 13 and 14-months) were arranged in factorial experiment conducted in randomized Complete Block Design with three replications. The results showed that all of the studied traits were significantly influenced by delaying the harvest age from 10 to 14-month age. Also, the results showed that the three promising sugarcane varieties significantly differed in stalk cane length, diameter, as well as Brix, sucrose purity, sugar recovery percentages, cane and sugar yields (Ton/fed.). Generally, promising sugarcane variety G.2003-49 was superior over the other two varieties i.e. G.98-28 and G. 99-160 in cane and sugar yields (Ton/fed.). | ||||
