Processors & Growers Research Organisation (PGRO) chief executive Salvador Potter said: "Growers have taken advantage of a cracking March for drilling more pulses."
Market prices remained steady despite some slight strengthening of the pound against the dollar, he said. The euro was very strong.
And although growers were still two to three weeks behind due to the cold nights, winter beans had established well.
"Spring beans are drilled in many areas but wetter fields will mean a few later-drilled crops but, with increasing temperatures, they should establish quickly.
"Pre-emergence herbicides require moist surfaces to work well and spraying should be delayed until rain is forecast," said Potter.
Lincolnshire-based PGRO specialises in applied research for processors and growers.
