Italy: Dragon fruit cultivation in Latina

According to the results of the tests carried out by agronomist Ottavio Cacioppo, dragon fruit can be considered an interesting exotic variety to be cultivated in the Lazio area.

"Research started in 1989 with an experimental crop of the yellow and red variety. The positive feedback we received from consumers, who were willing to pay up to 15,000 Liras (the currency used at the time) a kg, proved we were on the right path." 




"After a trip to Colombia in 1989 with the purpose of studying the particularities of the species, I have started tests in Latina."

The fruit is cultivated in non-heated greenhouses with a single autumn harvest for the yellow variety and two harvests (summer and autumn) for the red variety.

"After many years, I can say that the major difficulty to tackle is fruit abortion."

Artificial pollination is in fact used to increase production. Of course more fruit would be produced in a heated greenhouse, but costs would be higher too.

Experiments showed that, if a plant is protected from rain and wind, it can survive at temperatures down to -3°C.

In Colombia there are two harvests per year for a total of 10 kg per plant. In the Latina province, production is of around 6 kg/plant.

In Latina, there are 250 plants arranged on 1,000 square meters. The average production was of 6,000 kg a year.

Costs are really high, but greenhouse cultivation is justified by the prices: "currently, red dragon fruit has a wholesale price €6,25/kg, whereas the yellow variety is sold at €15/kg." 

Currently tests are being carried our on pink dragon fruit.
