摘要

1.本試驗爲測定尿素石膏鎂肥料對水稻之效果，採用隨機區組設計，三種肥料（尿素石膏鎂、硫酸錏、尿素）三種肥料量（80公斤、120公斤、160公斤）計得九處理，加對照區共十處理，重複六次，小區面積2.5m×4m=10平方公尺，合1/1000公頃。
2.根據試驗分析結果，不同肥料處理間之差異達極顯著水準。產量最高者爲尿素石膏鎂160公斤，次爲硫酸錏160公斤，尿素列第三。又肥料種類間之差異亦極顯著。
3.由產量構成因素資料分析，在各處理中可發現穗數爲產量增加最大之原因。
4.初步試驗結果顯示尿素石膏鎂爲一高度有效之稻田肥料。

1. This experiment was conducted in both crops of 1970 at the Chiayi Agricultural Experiment Station to evaluate the effect of Magypsum urea on the growth of rice. The variables included 3 types of fertilizer (Magypsum urea, Ammonium sulfate, and urea) and 3 doses of fertilizer (80, 120, and 160 kg per ha) with a total of 9 treatments which was arranged in a randomized complete block design with 6 replications. The plot size was 2.5×4m which was equivalent to 1/1,000 ha.
2. It was observed that difference among doses of fertilizer was significant at 1% level. Magypsum urea applied at 160 kg per ha afforded the highest yield, ammonium sulfate applied at 160 kg per ha came next, and urea applied at 160 kg per ha ranked third. Difference among types of fertilizer was also significant at the 1% level of probability.
3. From the data of yield components, it was noted that the number of panicles per hill was the major component that contributed to the yield increase.
4. The result of this experiment seems to indicate that magypsum urea is a highly effective fertilizer for paddy rice.
