Abstract
以水稻為主要試驗作物，在行政院農業委員會農業試驗所農田進行精準農業之試驗研究，分析與評量試驗農田植體營養狀態之變異與土壤性質變異之相關性，並進一步利用地理統計軟體繪製各試驗田區之植體營養變異分佈圖。根據農場室於水稻收穫後所得之產量與植體分析資料進行協同克利金（co-kringing）分析，以評估植體營養分對產量之最佳關係。發展及應用有效且精確的方法，藉以評量水稻營養分之空間變異，俾建立植體養分變異與作物生長變異之相關性。
Paddy rice is the main crop for the study. The experiment field of precision agriculture is located at Taiwan Agricultural Research Institute Experimental Farm. We have analyzed and evaluated the rice nutrient spatial distribution and the soil variation of the experiment farm. Geo-statistic sofiware and GIS were applied to map detailed plant nutrient distribution map of experiment fields. The rice yields and plant nutrition data were analyzed by co-kringing method to find the best relationship of rice nutrient and crop yields. For precision agriculture, efficient and accurate methods for assessing the spatial variability of rice nutrient, and relating it to yield quantity and quality component, must be developed and utilized in order to build the relationships between plant nutrient and growth variability.
