A lot of planning goes into a variety trial. Peters told growers to prioritize the crop species and type they are most interested in growing. After that, he said, growers need to identify sources and seed varieties, secure a suitable field with infrastructure, and recruit field help if necessary.
For a successful trial, Peters recommends that growers keep it fairly simple, trying no more than four or five varieties at first. To get the greatest benefit from running a trial, he suggests including one or two leading commercial varieties for the area, then perhaps one or two older standard heirlooms, and a couple of intriguing new varieties that may offer potential on the farm.
