| Abstract | ||
| Two field experiments were carried out at the Research Experimental Farm of Sabahia Agricultural Research Station in Alexandria during the two successive growing seasons of 2011/ 12 and 2012/ 13. G2006-77 sugarcane variety (Saccharum officinarum L) was cultivated to investigate the effect of irrigation regime and nitrogen fertilizer level and their interaction on sugarcane yield and its components. Main plots were represented by three irrigation regime:1- (large interval) 18 irrigations/ year was given to first treatment irrigation at (15 days interval in Summer, 20 days interval in Spring and Autumn and 30 days interval in Winter seasons), 2- (middle interval) 25 irrigations / year was given to second treatment irrigation at (10 days interval in Summer, 15 days interval in Spring and Autumn and 21 days interval in Winter seasons) and 3- (short interval) 32 irrigations / year was given to third treatment irrigation at (7 days interval in Summer, 13 days interval in Spring and Autumn and 15 days interval in Winter seasons,). The sub plots were used for the three nitrogen levels (140, 200 and 260 kg N / Fed). The results indicated that: The second regime middle irrigation intervals was insignificantly increased stalk length, stalk diameter, stalk yield, sugar yields, T.S.S (%), sucrose (%) and purity (%) compare with the first and third regime through the two successive seasons. Increasing applied N levels from 140 up to 200 Kg N /fed. significantly increased stalk length, stalk diameter, stalk yield, sugar yields T.S.S (%), sucrose (%) and purity (%). The interaction between irrigation intervals and nitrogen levels on the studied traits were not significant except sucrose (%) in the two seasons. | ||
