In Cambodian, vegetables are difficult to grow in the wet season due to the wet conditions. Vegetable grafting is a horticultural technique used to take advantage of genetic resources of multiple plant species in order to address seasonal challenges. This study evaluated the suitability of eggplant rootstocks used for tomato grafting for production in Cambodia. Three different eggplant rootstocks (i.e., local, market-available, and recommended eggplant cultivars) were grafted with the tomato scions, using cleft grafting methods. The grafted seedlings were planted in the field to determine plant growth and productivity. The results show that the survival rates and productivity of grafted tomatoes were significantly greater than non-grafted plants. Grafting tomato scions onto local or market available eggplant rootstocks can be used to deal with problem of too much water or rain at atypical times for tomato production in Cambodia.
