Sowing naked seeds is generally preferred in arid and semiarid regions. This research aimed to find the optimal dimensions for both pelleted and naked seeds based on seed distance in rows and field emergence irrigation setting in sugar beet (Beta vulgaris L.) cultivation under the environmental conditions of Central Anatolia in Turkey. For comparison, the research considered two field emergence irrigation conditions, namely, irrigated and non-irrigated, at 8 and 17 cm seed distances within rows for naked seeds of two dimensions: N3 .25-empty set4.50 and N3.00-empty set3.50 mm and for pelleted seeds of five dimensions: P3.50-empty set3.75, P3.75-empty set4.00, P4.00-empty set4.25, P4.25-empty set4.50, and P4.50-empty set4.75 mm. The results showed that the highest beet yield and refined sugar content were 66.67 and 10.31 t ha(-1), respectively, obtained in the plot that was irrigated and drilled with N3.00-empty set3.50 mm seeds at 8 cm sowing distance. The lowest values were obtained from the non-irrigated plot that was drilled with P4.50-empty set4.75 mm seeds at 17 cm sowing distance in all conditions. In field emergence irrigation conditions, planting pelleted seeds from 3.50 to 4.25 mm in dimension or 0.25-0.75 mm in thickness at row distances of 8 and 17 cm can be concluded to be the optimum application.
