This study consisted of 2 experiments that were carried out at El-Sabahia Research Station, Sugar Crops Research Institute (SCRI), Agricultural Research Center (ARC), (31° 12 N) during 2004/2005 (plant cane) and 2005/2006 (ratoon crop) seasons to investigate the effect of N fertilization levels; 160, 200, 240 and 280 kg/fed on behavior of natural flowering of 32 sugarcane genotypes from different origins. Results showed significant differences among the studied genotypes in their flowering % under different levels of N in plant cane and ratoon crop. The difference among N levels as well as the genotype × N levels interaction in their effects on % of flowered plants was significant in both plant and ratoon crops. The % of flowered plants within and between levels of N differed significantly in plant and ratoon crops. Moreover, increasing N levels caused a reduction in flowering behavior. The % of flowering   increased in older crops.

Key words: Flowering, first ratoon, plant cane and sugar cane.
