Early (‘Alaska’) and late (‘New Line Early Perfection’) processing pea cultivars were grown in all possible combinations of three row spacings and three populations during 1965 and 1966. Row widths of 9, 18, and 27 cm and population levels of 1,660,000, 1,110,000, and 550,000 plants/ha were used. Maturity, height, total number of nodes, lowest pod bearing node, average size of shelled pea, and number of ovule initials were not greatly affected by the treatments. Productivity per plant and plant population were inversely related. Yields generally increased with increased population and/or decreased row spacing. Greatest yields were obtained with the highest population grown in the narrowest rows.
