AB -The cucumbers were grown in three kinds of nutrient 150 ppm NO3--N, 150 ppm NH4+-N, and the mixture of 75 ppm NO3--N and 75 ppm NH4+-N, separately for seven days.  The best and the worst growth were in the nutrient of NO3--N and NH4+-N, respectively.  Although they took the same amounts of combined nitrogen from each nutrient, the better assimilation of NO3--N than NH4+-N in the cucumbers resulted in heavier dry weights, higher contents of total nitrogen, and higher soluble proteins contents in the leaves of cucumbers that grown in higher concentration of NO3--N.  The compositions of soluble proteins in the leaves of cucumbers were also influenced by nitrogen sources by showing their discrete electrophoretic patterns.
