Potato specialist developed a new way of measuring skin-set of potatoes

Knowledge Exchange Manager, Dr Bill Watts at AHDB Potatoes in the UK has developed a new way of measuring potato skin-set – a measurement that gives an actual numerical result.

“The traditional way of testing skin-set is putting a large sample through a barrel roller, and then make a judgement based on how they look after that” said Bill.

“Our system will actually give you a number, in newton-meters, for the force needed to break the skin of the tuber.

“We’re using a modified screwdriver that tests torque. Some growers say ‘I know what a set skin looks like, I don’t need that’ – but for us, when we’re running a trial and putting one option against another we can now put a value on it.

“Other growers are very interested, maybe in the future it will become something that will help them make decisions in the field.”
