摘  要
 

   土壤有機質是農田土壤肥力的重要指標之一,施用有機質肥料是增加土壤有機質含量最直接有效的方法。本研究目的在於調查分析甘比亞主要農牧廢棄物資源,以及探討甘比亞地區栽培水稻之最佳有機資材利用方法。由 1999 年甘比亞地區主要農業廢棄物調查分析結果顯示,分別含有氮量約 1,768 t 、磷量約 123 t 、鉀量約 2,124 t 。 1999 年甘比亞地區主要畜產廢棄物中,分別含有氮量約 27,607 t 、磷量約 13,527 t 、鉀量約 29,646 t 。本研究將稻殼、牛糞、米糠以體積比用量約 50:40:10 比例,可以製作出成分含量及品質穩定的牛糞稻殼堆肥,其中氮含量 0.53% 、磷含量 0.10% 、鉀含量 0.36% 、鈣含量 0.16% 、鎂含量 0.09% 、有機質含量 70.4% 。由 1999 年秋作及 2000 年春作水稻田間栽培試驗結果顯示,使用田菁 10 t/ha 配合尿素 100 kg/ha 處理及牛糞稻殼堆肥 10 t/ha 配合尿素 100 kg/ha 處理,所獲得的稻米產量較高且穩定,比空白對照處理可以增產約 13~20% 。綜合以上結果顯示,本研究之牛糞稻殼堆肥製作方法,以及牛糞稻殼堆肥 10 t/ha 配合尿素 100 kg/ha 處理,均可做為甘比亞栽培水稻之參考。

ABSTRACT
  Organic matter is often used as an index of soil fertility. However, the application of organic fertilizer or compost can significantly increase the content of soil organic matter. The purpose of this experiment is to study the effect of organic material on yield enhancement of rice in the Gambia. The results indicated that the estimated amounts of N, P, and K from the main crop residues in 1999 are 1768 tons, 123 tons, and 2124 tons, respectively. The estimated amounts of N, P, and K from the main livestock manure in 1999 are 27607 tons, 13527 tons, and 29646 tons, respectively. A good ingredient of compost should consider both in quality and practicality. Rice hull and cattle waste compost made from rice hull, cattle, and rice bran at the ratio of 50:40:10 by dry weight basis could get a stable quality. The N, P, K, Ca, Mg, and OM content of this cattle waste – rice hull compost were about 0.53%, 0.10%, 0.36%, 0.16%, 0.09%, and 70.4%, respectively. Field experiments showed that the growth and yield of rice on the application of green manure 10 t/ha plus urea 100 kg/ha and cattle waste – rice hull compost 5 t/ha plus urea 100 kg/ha have stable performance in both 1999 fall and 2000 spring cropping seasons. Rice yield of those treatments is higher than that of check plot by 13-20%. Therefore, this ingredient of cattle waste – rice hull compost and applied in rice field can be recommended to farmers in the Gambia. The application rates with cattle waste – rice hull compost 5 t/ha plus urea 100 kg/ha were appropriated and suitable for rice production.

Key words: organic material, rice, the Gambia.
