| Abstract | ||||
| Two field trials were carried out at El-Mattana Agricultural Research Station, (Qena Governorate) in 2001/2002 and 2002/2003 seasons. Each experiment included 18-treatments representing three number of ploughings, 2, 3 and 4, three varieties performance namely, G.T.54/9, F. 153 and Ph 8013 and two nitrogen fertilizer levels, 180 and 210 kg N/fed. Treatments were distributed in a split split plot design with four replications. Number of ploughings were assigned in the main plots, whereas varieties were assigned to the sub plots and nitrogen fertilizer levels were randomly distributed in the sub-sub plots. The result showed that number of ploughings attained a significant difference in number of plants/m2, leaf area (cm2/plant), number of millable cane (1000/fed) and cane yield (ton/fed) in the 2nd season as well as brix% and purity% in the two seasons. Ph 8013 variety significantly surpassed in number of plants/m2, brix%, sugar recovery% and number of millable cane (1000/fed), cane yield (ton/fed) as well as sugar yield (ton/fed) in the two seasons and purity% in the 2nd season. Nitrogen fertilizer showed insignificant effects on all growth traits under study in the two seasons. Variety Ph 8013 gave the highest cane and sugar yields (61.54 and 6.34 ton/fed) along with 2 ploughings and 180 kg N/fed. | ||||
