Both banana and guava can be harvested whole year-round in Taiwan. That makes yield estimation through short-period crop-cutting system infeasible. In the project, we proposed to estimate the yield by collecting data continuing recorded by the farmers. This project include construction of the data collecting process, data collection and statistical analysis of the yield data. This project firstly will provide the estimates for the yields of banana and guava in 2011. While performing sampling surveys, the estimates or different variance components will provide insight into the elements that contribute the most to the sampling variability. The knowledge about the variance components will allow us to refine the sampling scheme in the future to achieve an even more accurate estimate about the yield of banana and guava. Hopefully, the results of this project will assist to develop a proper procedure to estimate yield through farmers records in the near future. -作物單位產量抽樣調查經濟敏感性作物crop yieldsampling surveyeconomically sensitive crop
