Abstract
Two field trials were carried out at El-Mattana Research Station, Gene Governorate,Upper Egypt in 1998/2000 and 1999/2002 seasons to study the effect of three sugar cane varieties (G.85/37, G.84/47 and 0.754/9). and 3 N-levels (120, 160 and 200 kg N/fed) on cane yield and quality under surface developed irrigation system.The obtained re-suits showed that the tested varieties differed significantly in stalk length, In the Is' and 2" seasons and, Cane yield significantly by the used varietues in the 2" season only. Sugar yield, sugar recovery% and purity% were not affected by the tested varities.There was a significant and gradual increase in stalk length and cane yield as N doses were in­creased up to 200 kg N/fed. For both seasons.Sugar recovery % and purity % were statistically and negatively affected by increasing N level in theist and 2" seasons.
