Pepino, native to South America, is an evergreen, exotic plant species that belongs to the Solanaceae family and has been known and grown for a long time. In the study, the effect of different planting months, April and May in 2004 and 2006, on fruit quality and yield were investigated. Fruit diameter and length, fruit weight, fruit numbers per plant and yield were considered with climatic factors. The experiments were conducted in a split-plot design with three replications, and all data were subjected to statistical evaluation. In 2004 with an April planting time, there were significant differences in fruit diameter, weight, fruit number per plant and yield while fruit length showed numerical difference. With the exception of fruit length, the other parameters did not show statistically significant differences although all data in 2004 were higher than those for 2006 numerically. It could be suggested that in the growing of pepino numerical differences in fruit diameter, fruit weight, fruit number per plant and yield are affected by climatic factors.
