Seedling Beet Application in Sugar Beet Agriculture

摘要

Early sowing is an important factor in sugar beet agriculture in order to increase yield and quality. Sugar beet seedlings are grown in greenhouse and planted as early as the permission of weather conditions increase yield and quality. For this purpose, 5 ha seedling and normal beet were grown for both areas in Ararat province; yield, quality parameters and economical evaluation were done. 0.5 ha in each 10 plots were planted and sowed for both methods in the test and the results were compared with t-test. As a result of the test, 11.26 t ha~(-1) yield, 0.46°S sugar content, 0.57°S refined sugar content and 2.02 t ha~(-1) refined sugar yield increase were obtained in seedling method compared with conventional method. Because of high application cost of seedling method, 764.48 $ ha~(-1) less net income was obtained, though yield and quality increase. This amount corresponds to approximately 6.95 t beets. 18.21 t ha~(-1) yields are required to taken in seedling method in order to obtain equivalent income with the conventional method. However, if supplying the seedlings outside of the farm instead of growing in the farm, seedling unit cost can be reduced and it may be possible to apply of this method, which provides increased production, in sugar beet production area.
