On October 4, 2021, in the Field Practices in Agricultural Production Systems (Crop Course), the students harvested rice for the yield survey in the experimenal paddy field for long-term continuous use of fertilizer. In this paddy field, a total of 12 plots were set up in various combinations, from no fertilizer at all to three elements with standard fertilizer amounts, and then to double the amount of fertilizer, and cultivation examinations have been conducted with the same variety without changing the fertilization method for more than 40 years since the farm was established. In the crop course of this practical training, fertilization, puddling, sowing, and transplanting were carried out in the spring semester, and on October 4, the first day of the fall semester, the students harvested for the yield survey. In the practice schedule, rice yield components are surveyed to estimate the rice yield and the taste of cooked rice is compared among treatments. Students will analyze the effect of long-term fertilization on the yield and quality of rice.
