The present study was carried out at Guneid Research Sugar Cane Center during the two seasons of 2014 and 2015.The objective was to investigate the effect of three irrigation intervals 7, 10 and 14 days and two planting methods manual and mechanical on sugar beet crop growth and yield. The parameters measured were germination ratio, root thickness, root number/ha, leaf weight, root crop yield, polarization, estimated recovery sugar and sugar beet production. A split plot design with four replications was used. Irrigation intervals significantly (P≤0.05) affected root crop yield, root thickness and sugar beet production. The maximum values of root crop yield (65.4 ton/ha) and root thickness (35.2 cm) were obtained under 10 days irrigation interval, while the maximum values of sugar beet production (10 ton/ha) was obtained under 7 days interval. Methods of planting significantly (P≤0.05) affected root crop yield, root thickness, root number/ha, germination ratio, polarization, estimated recovery sugar and sugar beet production. The maximum values of root crop yield (65.2 ton/ha), root number/ha (67375 roots/ha), germination ratio (79.8%) and sugar beet production (9.7 ton/ha) were recorded for the manual planting method, while the maximum values of root thickness (35.6 cm), polarization (18.4%) and estimated recovery sugar (15.8%) were recorded for the mechanical planting method. The combined of irrigation intervals and sowing methods (irrigation intervals 7 days with manual planting methods and irrigation intervals 10 days with mechanical planting methods) resulted in hiegh polarization (18.5, 18.5 %), estimated recovery sugar (16, 16 %) and sugar beet production (10.7, 9.7 ton/ha), respectively, compared to other treatments. Irrigation intervals 10 days with mechanical planting method can be recommended to prevent loss of sugar content in sugar beet roots.

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.
