SEED YIELD, SEED WEIGHT, PERCENT PROTEIN AND PROTEIN YIELD OF FIELD PEAS AS AFFECTED BY SEEDING DATES

Abstract

The effects of seeding dates on yield, seed weight, percent protein and protein yield of field peas (Pisum sativum L.) were determined by seeding four cultivars at five dates from 1970 to 1973 at two locations in Manitoba. Early seeding resulted in higher yields and heavier seeds. Protein content was lower in early-seeded peas, but the protein yield per unit area was higher than the late-seeded peas. In Manitoba, field peas should be seeded before the 1st of June to obtain high yields of both seed and protein.
