Effects on Quality Properties and Plant Distribution Uniformity on Row Space of Techniques of With Thinning and Block Sowing of Sugar Beet

In without thinning sowing applications, it is needed to high field emergence. In this situation, it can be increased the seed spacing within the row and can be obtained adequate plant number and distribution. Without thinning sowing of sugar beet in Turkey, it is made at 15 cm of spacing within the row. However, expected 20-25 cm of spacing within the row, it cannot be obtained in field con-ditions. In this reason, the sowing is still made 5 and 8 cm of spacing within the row. This made mandatory the thinning application. In this research, it was com-pared with thinning precision sowing (6 cm) and changing spaced sowing (block sowing) (21+5.3 cm) methods in field conditions. Obtaining average spacing within the row of sowing distances in the field conditions were obtained as 12.10 cm at thinning sowing and as 14.59 cm at block sowing. The variation coefficient of spacing within the row dispersion, bud rising ranks in the field and number of the plants in da were obtained as 52.16% and 65.19%, 60.84% and 67.93%, 20684 and 10524, respectively. Application of the thinning in block sowing caused more thinned area at ratio of 26% and among sugar beet quality criteria except α-Amino N were determined to be not occurred significant differences. In result of the research, it was determined to can be applicated of block sowing method in the regions where was up to 50% of field emergences in sugar beet production.
