Abstract
This research was conducted to determine the effect of fertilization programs on crop growth, nutrient uptake and yield of strawberry and salt accumulation in PE film house soil. To achieve these, experiments were conducted through two years with various fertilization program such as traditional fertilization(A), recommended fertilization of Rural development administration (B), Tochigi prefectural experiment station (C) and Nonsan strawberry experiment station (D), and control (E). In 1st year, statistical differences in growth characteristics were not observed among treatments except (E). Yield per 10 was the highest in (D) followed by (A), (B), (C) and (E) and there was the statistical difference between (D) and (E). In the 2nd year experiment, growth characteristics and yield showed similar trends to those of 1st year experiment. In the results of soil analysis of 2nd year, the soil pH of all treatments were in the acceptable range, while electrical conductivity of (A) and (D) were 2.36 and 2.19 %$dS{\cdot}m^{-1}$, respectively. After finishing of strawberry cultivation, nitrate concentration in soil solution of (A) and (D) were 74.6 and 65.0%$mg{\cdot}L^{-1}$ and Na in those were 3.71 and 3.53 $cmol+kg^{-1}$, respectively. Above results indicated that (A) and (D) were good fertilization program for strawberry cultivation, but those also resulted in accumulation of $NO_{3-}N$ and Na in PE house soil.
