Cramer said there isn’t much need to develop a variety for sizing.
“Size often depends upon plant density — the more space you give an onion plant, the larger bulb it produces,” Cramer said.
Size requirements have evolved, said Bill Coombs, salesman with Arrey, N.M.-based Desert Springs Produce.
“We grow onions of specific sizes for specific customers, and that is a big change from the way things used to be,” he said. “In days of old, everything was as big as you can get. But the market is to take care of customer needs.”
