The objective of this study was to examine the effects of grafting and kinds of rootstocks on yield that are economically feasible for the watermelon producer. Fruit characteristics and quality attributes of grafted plants in open field conditions were also analyzed. The tongue approach grafting method was adopted. Three Watermelon cultivars of 'Crimson Tide', 'Dumara', and 'Farao' were used as the scion. Three hybrid squashes of 'Dynamo', 'RS-841', and 'Shintosa' were used as rootstocks. Results showed that some fruit quality indicators such as dry matter, total soluble solids, total sugar and titratable acid contents were lower in grafted plants while lycopene contents remained unchanged. The pH was slightly altered by grafting. Use of rootstock did not show advantages at comparable fruit quality indicators. Results also showed that fruit shape index, rind thickness, fruit weight, total yield and marketable yield were significantly influenced by grafting. Use of rootstocks significantly increased previously mentioned values which is related with yield, as compared to the non-grafted plant. Analyses proved the use of rootstocks as economically feasible and an advantageous alternative in watermelon production.
