Two field experiments were carried out at Shandaweel Research Station, Upper Egypt in the two successive growing seasons of 1997/ 1998 and 1998/1999 to study the effect on nitrogen and zinc fertiliza­tion on yield and quality of sugar cane plant crop. Each trial included nine treatments representing the combination between three nitrogen levels (160, 190 and 220 kg N/fed) and three doses of zinc (0, 25 and 50g Zn/fed). A cohplete randomized block design with three replica­tions was used. Results showed that zinc levels significantly affected sugar yield, reducing sugar % and sucrose % in the 1st and 2nd seasons. On the other hand, it was noticed that cane yield significantly responded to zinc levels in the second season while number of millable cane signifi­cantly responded to zinc levels in the first season. Generally, applying 50 g Zn/fed produced the highest production of the studied characters. Re­garding the effect of nitrogen levels, it was revealed that except for sugar yield, number of millable cane, cane yield. reducing sugar, sucrose % and purity % significantly responded to applied nitrogen levels in the 1st and 2nd seasons. Matly, increasing N fertilizer up to 220 kg N/fed increased the values of studied traits.
