The weather has once again made for a challenging season, British Tomato Growers Association chairman Nigel Bartle said at the conference.
"It was a slow and expensive start to the season, and although the middle of summer was great, you never make up the lost time," he told Grower.
Meanwhile, Dutch tomato production is expected to increase by nearly five per cent in 2013. "There's always a lot of imports, which have an impact, but it's the weather that dictates demand," said Bartle.
He added that the market share of UK-grown fruit "is no longer going backwards" but said: "We don't want consumers buying tomatoes just because they're British, but because they're better."
