This study was conducted to investigate the effect of grafting methods on plug seedling quality, growth after transplanting, and yield of oriental melon that those seedlings were raised in the 32 hole plug tray for protected cultivation. Number of leaf and leaf area in approach grafting were higher until 15 days after grafting but lower on 20 days after grafting. Plant height, stem diameter and content of chlorophyll were nearly the same of each grafting methods on 20 days after grafting. Growth of top part, that is, plant height, leaf number, and leaf area on root removed single cotyledon ordinary splice grafting was the highest among the grafting methods. In the underground part, dry weight of root was high and T/R ratio was the lowest. Seedling quality of root removed single cotyledon ordinary splice grafting was the highest among grafting methods before transplanting. Plant height, number of leaf, leaf area and dry weight of root removed single cotyledon ordinary splice grafting in the growth of field were the highest on 30 days after grafting among grafting methods and days required for first flowering was also shorter, 38.4 days among grafting methods. But Fruit weight, content of soluble solids, fruit hardness, and color characteristics in fruit quality were insignificant among each grafting methods. Consequently, grafting methods influenced on the seedling quality, of oriental melon early growth after transplanting and yields. It was concluded that root removed single cotyledon ordinary splice grafting was the best methods in present study. It will be needed to convert grafting methods. Thus new grafting method should be applied.
