Fruit Yield in Cucumber Grafted on Different Rootstocks

Grafting is an alternative technique often recommended for cucumber culture in protected environments. This study aimed to study yield of cucumber grafted on different rootstocks compared to non-grafted plants in non-infected soil. Five treatments (Japanese cucumber hybrid 'Tsuyataro' without grafting, grafted on squash hybrids 'Shelper', 'Excitte Ikki', 'Daiguy' and 'Keiji') were evaluated in a completely randomized blocks design, with four repetitions and six plants per plot. Lesser fruit yield was obtained in cucumber grafted on 'Keiji', while cucumber grafted on other rootstocks did not differ from non-grafted plants. So, in the absence of soil borne diseases, grafting did not increase cucumber fruit yield, and, depending on rootstock, grafting can decrease production compared with non grafted plants.
