All Good's Simon Coley attended to learn more about the crop.
He was looking at expanding his business to make oat-based smoothies, he said.

Otama cereal farmer Mike Solari said he came because he was considering growing oats. He already grew wheat, barley and peas.
"Oats are a healthy food. There's a market demand for it. Every year production is going up," he said.
