| The present investigation was carried out at Shandaweel Agricultural Research Station, Sohag Governorate [26.5013° N, 31.7651° E] during 2016/2017 and 2017/2018 to investigate the effect of three row spacing (80, 100 and 120 cm),and three nitrogen levels (180, 210 and 240 kg N/fed) on yield and quality of three sugarcane varieties i.e. [G.3 (2003-47), G.4 (2004-27), in addition to (commercial variety) G.T.54-9 (Each experiment was carried out in a randomized complete block design using a split-split plot arrangement with three replications. The results showed that planting sugarcane in rows spaced at 80 cm apart attained a significant increase in cane stalk height, number of millable canes and cane yield/fed. Significant increase in stalk diameter, brix, sucrose and sugar recovery percentages as well as sugar yield/fed were recorded surpassed the other varieties recorded at 120 cm row spacing in both seasons. The results showed that sugarcane varieties differed significantly in all studied traits. G.T.54-9 variety in stalk height and cane yield/fed, while G.3 (2003-47) variety was superior in stalk diameter, brix, sucrose sugar recovery and sugar yields/fed in both seasons. G.4 (2004-27) variety attained the highest values of number of millable canes/fed in both seasons. , Raising N fertilization level up to 240 kg N/fed resulted a significant increase in stalk height, diameter, number of millable cane/fed, cane and sugar yields/fed, while the application of 210 kg EFFECT OF ROW SPACING AND NITROGEN216 N/fed led to a significant increase in brix, sucrose and sugar recovery percentages, in both seasons. | ||||
