Both have some tolerance to red clover vein mosaic. These are replacements for the variety Corvallis. It is important to choose a field with uniform fertility, soil type, slope, and drainage to get a uniform pea crop. The best soils are silt loams, sandy loams, or clay loams. Peas grown on wet soils develop shallow root systems which cannot supply the plant's water requirements when the soil dries out later in the season.
Root rot is often a problem in wet soils.
Determine corrective lime and fertilizer needs by a soil test. Adjust pH to 6.5 or higher for maximum yields. Land should be plowed, harrowed, and a cultipacker used lightly to ensure a firm seed-bed. The land should be level in order to make harvesting more efficient. Care must be excersised in avoiding subsurface compaction since this contributes to limited aeration and rooting and predisposes roots to a number of root pathogens.
