영문 초록

In order to select the best varieties and cultivation methods for the production of domestic wheat for Hodugwaja(a walnut shaped confection), we carried out a 3-year experiment (2015~2017) to investigate the effect of different factors (crop variety, planting date, nitrogen fertilization) in a double cropping system (wheat then rice) on crop yields in the Cheonan area. Rice is the second crop in the system, and requires an accumulated temperature for 40 days of about 840~930℃ to ensure ripening. Transplanting dates for rice between June 29 and July 6 were suitable; transplanting on or after July 13 does not ensure ripening. The daily hours of sunshine ranged from 6.3 to 6.5 hours, which were slightly higher than the optimum of 6.0 to 6.1 hours. The higher the nitrogen fertilizer treatment, the higher culm length, and spike length of wheat. The yield of wheat per 10a tended to increase as the amount of nitrogen fertilizer increased. Wheat yields were highest for the Sooan variety, followed by Goso, followed by Keumgang. The number of days from transplanting to heading of rice were shortest for the Jopyeong variety followed by Unkwang, followed by Haedam. The yield of milled rice per 10a increased as the transplanting date was earlier and the transplanting date of June 9 showed the average yield of more than 500 kg in three varieties. From the results of the experiment, we recommend the Goso wheat variety and the Haedam rice variety for growing in a double cropping system under the climatic conditions of the Cheonan area.
