| Abstract | ||||
| Two field trials were carried out at Mattana Agricultural Research Station, (Qena Governorate) on sugarcane grown in 2002/2003 and 2003/2004 seasons. Each trail Included eighteen treatments represent the combination between three levels of nitrogen (180, 210 and 240 kg N/fed), phosphorus fertilizer (30, 45 and 60 kg P205/fed) and two levels of potassium (24 and 48 kg 140/fed). Sugar cane was planted during the first week of March and harvested after12 months. The commercial planted sugarcane variety viz. Ph. 8013 was used. A split plot design was used in both seasons. Nitrogen levels were allocated in the main plots while the combinations of phosphours and potassium levels were random* distributed 111 the sub plots. The results showed that Increasing nitrogen fertilizer levels significantly number of plants/&, cane and sugar yields in the I' season and sugar recover" in the 2'4 season, while stark height and number of minable cane/fed were significantly in both seasons. Increasing phosphours fertilizer levels significantly number of plants/m2, stalk height, reducing sugars, purity% and sugar recovery% as well as cane yield and sugar yield in the 2•4 season and number of minable cane/fed in both seasons. Increasing potassium fertilizer levels significantly number of millable cane/fed in the 2r0 season. While, leaf area and stalk height in both seasons. The highest cane yields (46.60 and 49.77) (tons/fed) were obtained by applying 240 kg N/fed, 45 k9 PA and 24 kg K,0/fed in the 1ci season and 240 kg N/fed, 30 kg PA and 48 kg 40/fed in the 2'd season, respectively. The highest sugar yields (5.75 and 6.13) (tons/fed) were obtained by applying 240 kg N/fed, 45 kg PA and 24 kg 40/fed in the lg season and 210 kg N/fed, 30 kg PA and 24 kg 820/fed in the 2'4 season, respectively. | ||||
