 Abstract
To develop a technique for efficient management of fertility for cucumber in greenhouse, a quick test method to quantify nitrate () content in soil solution and leaf petiole juice using a simple instrument that are easy to use for farmers was investigated. N fertilizer (urea) was applied at 0, 50, 100 and 200% levels of the recommended application rate from 30 days after transplanting to harvest by soil fertigation treatments. Stable results were obtained from analysis of nitrate () using top or leaf petioles collected between 10 to 11 am in the morning. Under the semiforcing culture, content of leaf petiole juice was highest at 60 days after transplanting (DAT) at all fertigation treatments. Appropriate content of leaf petiole juice was at 45 DAT, at 60 DAT, at 75 DAT, at 90 DAT, and at 105 DAT. In addition, appropriate content of soil solution was at 45 DAT, at 60 DAT, at 75 DAT, at 90 DAT, and at 105 DAT. The cucumber yield at 100% N level of fertigation was and no difference in yield was found at 200% N level of fertigation. However, there was 12% decrease in yield at 50% N fertigation and, 17% decrease at 0% N fertigation. Under retarding culture, concentration of leaf petiole juice was highest at 55 days after transplanting (DAT) at all fertigation treatments. Appropriate content of leaf petiole juice was at 45 DAT, at 55 DAT and at 65 DAT, respectively. Appropriate content of soil solution was at 45 DAT, at 55 DAT, at 65 DAT, respectively. The cucumber yield at 50% N fertigation was not different from of 100% N fertigation level and even with that of the 200% N fertigation. However, there was 21% decrease in yield at 0% N fertigation.
