| Abstract | ||||
| The present work was conducted at El-Mattana Research Station (Upper Egypt) in the two successive seasons of 1996/97 (the 1st ratoon and 1997/98 (the 2nd ratoon) to evaluate three sugar cane varieties (G.T. 54-9, F.153 and G.74-96) grown under two irrigation systems (drip and furrow irrigation) and fertilized with three nitrogen levels (172.5, 207 and 242.5 kg N/fed). The obtained results showed that stalk height and cane yield were significantly affected by irrigation systems in the 1st and 2nd ratoon crops. Sugar yield was significantly affected by irrigation systems in the 2nd ratoon only. lrrgation systems failed to reach the level of significance in their effect on sugar recovery %, juice purity %. Sugarcane variety &T. 54-9 attained a significant superiority in stalk height, stalk diameter, cane and sugar yields over F.153 and G.74-96 varieties. Sugar recovery and purity percentages were not affected by the tested varieties. There was a significant and gradual increase in stalk height, stalk diameter, cane and sugar yields as N levels were increased up to 241.5 kg N/fed for both ratoons. Sugar recovery % and purity % were statistically and negatively affected by increasing N level in the 2nd ratoon only. | ||||
