The importance of the sugar beet crop to agriculture is not confined only to sugar production, but also it is adapted to saline, sodic and calcareous soils, therefore it can be planted in new reclaiming lands in Egypt, in this respect two field experiments were conducted at Nubaria Region, to study the effect of three sowing methods and planting density on yield and quality of sugar beet (Beta vulgaris L.) cultivar monogerm (cv. Salama) during 2020/2021 and 2021/2022 seasons. Treatments were organized in a split-plot design in three replicates. The three methods of sowing i.e., mechanical planting by a planter in rows (M1), hand sowing on ridges at the two sides of the ridge (M2) and hand sowing on ridges at one side of the ridge(M3) randomly allocated to the main plots, while, the three-planting density (60000, 64000, and 68000 plant/fed) were assigned randomly within the subplots. Generally, the results showed that planting methods such as the mechanical method in rows (flat) (M1) or on the two sides of ridges(M2) in addition to the plant density (60000 or 64000 plants/fed) and their interaction increased productivity parameters of sugar beet as well as increased root and sugar yield and sugar quality under the conditions of Nubaria Region.
