A South Australian teenager has grown the world's biggest cucumber - and it wasn't much shorter than him.
Keegan Meyers' 1.3 metre gourd, which was overripe and had to be fed to the family chooks, weighed five kilograms and beat the previous record by about 10cm.
"We planted the seeds in January and one of the cucumbers was particularly large. It was past eating so we let it grow," the 13-year-old told AAP on Thursday.
"I was thinking how big can it get? What happens if it's too big?
"It was a three-person job to get it off the vine and out of the glasshouse."
The record was verified by the Australian Giant Pumpkin and Vegetable Society earlier this month.
But Keegan, from Elliston on the west coast of the Eyre Peninsula, couldn't munch on the fruits of his labour because the cucumber was a tad beyond it.
"It was starting to go a little rotten so we fed it to our chickens," he said.
Keegan plans to grow more big vegetables next year but expects some competition from his sisters.
