The present research study was carried out at Guneid Research Sugar Cane Center during the two seasons of 2014 and 2015.The objective was to investigated the effect of four tillage systems (mouldboard plowing, disc plowing, chisel plowing and disc harrowing) and three irrigation intervals (7, 10, and 14 days). The parameters measured were some crop parameters (germination ratio, root thickness, root number per hectare, leaf weight, root crop yield, polarization or sugar content, estimated recovery sugar and sugar beet production. A split plot design with four replications was used in this study. Different tillage systems significantly (P≤0.05) affected root number per hectare and germination ratio. The maximum value of root number per hectare 62254 roots/hectare, germination ratio (76.2%) and sugar beet production (10 ton/hr) and were given by disc plowing treatment, while the maximum root thickness (35.5 cm) were recorded by chisel plowing treatment and the maximum values of polarization or sugar content (18.6%) and estimated recovery sugar (16.9%) were recorded by disc harrowing treatment. While the minimum values of root crop yield, (58.55 ton/hectare) and germination ratio (66.5%) were given by chisel plowing treatment. Also irrigation intervals significantly (P≤0.05) affected root crop yield, root thickness and sugar beet production. The maximum values of root crop yield (65.45 ton/hectare) and root thickness (35.2cm) were obtained under an10 days irrigation interval, while the maximum values of sugar beet production (9.71 ton/hectare) was obtained under a 7 days irrigation interval. It was concluded that using disc plowing increased sugar production from sugar beet crops at Guneid Research Sugar Cane Center.
