Two field experiments were conducted at Shandaweel Research Station (Sohag Governorate) in 1994/95 and 1995/96 seasons to study the effect of irrigation regime and nitrogen fertilization on yield and its attributes of the plant crop of sugar cane. Sugar cane cultivar viz G.T.54-9 was used in this investigation. Each field trial induded nine treatments represent the combination between three irrigation regimes [1.Tradibonal irrigation regime used by sugar cane growers (irrigation at 10-day intervals in summer, a 15-day intervals in spring and autumn, and 20-day intervals In winter season) with a total number of 23 irrigations; 2. Irrigation at 7-day intervals in summer, 14-day intervals in spring and autumn, and 21-day interval in winter seasons with a total number of 28 irrigations and 3. Irrigation at 14-day intervals in summer; 21-day intervals in spring and Autumn 28-day intervals in winter with a total number of 17 irrigations] and three nitrogen levels (120, 180 and 240 kg N/fed). The obtained results showed that sugar recovery %, number of millable cane and sugar yields were insignificantly affected by the applied irrigation regimes. Cane yield was insignificantly responded to nitrogen fertilization levels. However, number of millable cane and sugar yield were significantly affected by N-levels in the 2n^d season only. Sugar recovery % insignificantly affected by N-level in the 1⁵¹ season only.
