 note = {Effects of tomato cultivation methods, fertigation with different fertilizer application rates, organic fertigation using CSL (Corn Steep Liquor) and hydroponic were compared on the yield, sugar content and δ^15N value. Sugar contents were inversely proportional to the yield. The results were induced not by the kinds of nitrogen source (organic or inorganic) nor by the nitrogen application rate but by the water application rate. Using the two source model δ^15N value, the higher the nitrogen application rate was, the lower the dependence rate to the soil nitrogen was. Hence, soil nitrogen plays an important role in the lower nitrogen application rate, to the increase of tomato yield.},
