A field research was performed with four treatments and four replications, which had the objective of ascertaining the Coconut Fiber (CF) impacts associated with lime addition on soil traits and arsenic uptake in green bean (GB) stems and seeds and yield and yield composition. The results showed that the lime, combined with CF, increased the pH level and farmland arsenic content of the soil. Arsenic content in stems and in GB seeds of the lime associated with CF treatment was lower than that of the control up to 32.0% and 50.0%, respectively. The lime combined with CF treatment raised pH and EC in the soil. The Arsenic accumulation of GB stems and seeds was lower than those of the control treatment up to 11% and 50.0%, respectively. The lime and CF amendment reduced the GB arsenic accumulation and increased the yield and yield traits. The maximum soil traits were obtained from using the lime combined with CF treatment of all measured treatments, and significantly different. The highest GB yield reached 2.45 t ha^-1 in amendment of lime combined with CF and the lowest yield (1.9 t ha^-1) at chemical fertilizer treatment alone, which was 22.5% higher than that of chemical fertilizer application only.
