Abstract:

This research was carried out in Homs Agriculture Researches Center, General Commission for Scientific Agricultural Research (GCSAR), Homs, Syria, during 2010, 2011 seasons to study effect of planting method (rows and drills) and tillage depth (deep: 50-55 cm, medium: 30-35 cm, shallow: 10-15 cm) on some growth attributes, yield and quality traits of sugar beet (Agora variety) in Homs region (middle of Syria). Split plot design, with three replicates was used. Results showed that planting on rows improved leaf area and net assimilation rate, but doesn’t affect leaves number. Deep tillage achieved the best values in growth attributes. Differences in quality traits (sucrose and purity percentages) were not significant, while root yield increased significantly in deep tillage (61.75 ton/ha) compare to medium and shallow tillage (55.05, 54.47 ton/ha) respectively. This cause an increasing in true sugar yield, so deep tillage surpassed medium and shallow tillage by following values (8.83, 7.92, 6.31 ton/ha). On the other hand planting on rows surpassed planting on drills in all of quality and yield traits.

Key wards: Planting method, Tillage depth, Growth attributes, Yield and quality traits, Sugar beet.
