| In order to evaluate the effect of salinity content in soil on chemical composition and productivity of rice which is suitable for the reclaimed saline paddy field, yield components and yield were investigated in 2,000 at reclaimed paddy field of Kwangyang bay in Korea. Heading date was early with Aug. 15 in soft salinification of 0.1 percent and late with from Aug. 20 to Aug. 25 in heavy salinification of 0.4 and 0.8 percent. Brown rice yield was highest in soft saliniflcation of 0.1 percent with 599kg/10a and was decreased with from 568kg/10a to 446kg/10a in heavy salinification of 0.4 and 0.8 percent. The correlation coefficient between brown rice yield and content of soil chemical composition, on organic matter, phosphate, nitrogen, potassium, calcium, and magnesium showed highly positive correlation and was shown negative correlation with pH meter. Judging from the results reported above, optimum salinification of saline paddy field seemed to be 0.1 percent. |
