RESPONSE OF YIELD AND QUALITY OF SUGAR CANE TO NITROGEN AND ZINC FERTILIZATIO

Abstract
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.
