Fig. 2. Effects of application of dedicated fertilizer on the rice yield in rice-ratoon rice system. The data in the figure were from seven experimental sites with yield increasing effect. The middle solid line represents the median value and the hollow rectangle represents the mean value. The upper and lower vertexes of the box and the upper and lower solid lines represent the upper and lower vertexes of the boxes, the maximum and the minimum, respectively. Different lowercase letters indicate significant differences among the three treatments in the same growing season.
