【 摘 要 】

In this study, the two different treatments are continuous rice and rice in rotation with bean, and the response is the normalized difference vegetation index (NDVI) of rice or the rice yield. This study is to determine whether the rice in rotation with bean results in a significant effect - increasing the rice yield. In this completely randomized experiment, we randomly assigned 40 samples to the continuous rice and 40 samples to the rice in rotation with bean. Then the rice NDVIs of all 80 samples were computed. Because the statistical significance of the rice NDVI of the rotation treatment was observed in the experiment, we can be confident in the conclusion that it was the difference in treatments that resulted in the difference in the rice yield. That is, we can be confident that a cause-and-effect relationship between the rice in rotation with bean and the rice yield increase has been found.
