Green Pea

Green field pea (Pisum sativum L.) genotypes were grown in the field and harvested before and after exposure to moist conditions. The seeds were evaluated for percent bleaching and intensity of green color. Samples from the first harvest were placed on moist paper in petri dishes for later recording of percent hard seeds and color. Percentage of bleached seeds and color at last harvest gave a good evaluation of resistance to color loss of the genotypes. Percentage of hard seed was strongly correlated with percentage of bleached seeds (negative) and color at last harvest (positive), and would provide the basis of a screening technique. However, non-soaking on moist paper may be associated with cooking quality, in which case the method would be of value in selecting lines for the split green pea market, but not for the whole green pea market.Key words: Pea (green field), Pisum sativum L., cotyledon color, seed bleaching

Very High

Field studies were conducted in 1973 and 1974 to evaluate the effects of light intensity on the quality and yield of the green field pea (Pisum sativum L.) ’Triumph’. The treatments included a control with no shading (80 klx) and shading with one (31 klx) or two (9 klx) layers of screen material for a 3-wk period before maturity. Shading resulted in a significant decrease in seed weight and yield and a significant increase in protein content of the seed. The effect of shading on viscosity of the cooked samples was quadratic, implying that viscosity only decreased at very high levels of shading. Shading also tended to reduce loss of green color in the seed cotyledons.

QUALITY, YIELD AND WEIGHT PER SEED OF GREEN FIELD PEAS AS AFFECTED BY SOWING AND HARVEST DATES

Cooking Yield

The green field pea (Pisum sativum L.) cv. Delwiche Scotch Green was sown at two dates and harvested at five dates in the field in 1971–1973 to determine the effect on quality, yield and weight per seed. The green color deteriorated with delay in harvesting. Rate of color loss varied from year to year, probably due to rainfall patterns. Differences in protein percentage due to sowing date varied from year to year, resulting in no significant difference over the 3-yr period. Viscosity of peas after cooking, yield and weight per seed were higher in the early than in the later sowing.

High rates of phosphorus (P) banded with or near the seed did not consistently improve seed yield or cooking quality of yellow field pea (Pisum sativum L. ’Century’) in soils initially moderate to high in P. Triple superphosphate applied at 50 kg ha−1 P2O5 with the seed, in rows spaced 30 cm apart, resulted in small decreases in seedling stands, but generally did not reduce yields.Key words: Field pea (Pisum sativum L.), seeding date, nitrogen, phosphorus, fertilizer placement, cooking quality

Nitrogen Phosphorus

The yellow-seeded field pea (Pisum sativum L. ’Century’) was grown at two levels of soil moisture, two levels of N and P and harvested at four dates in a 3-yr field study to determine the effects of these factors on cooking quality as indicated by the color, weight and viscosity of the puree of cooked samples. Nitrogen lowered cooking quality where yields were not improved but maintained quality when yield was increased. Phosphorus applications improved yield and cooking quality, with highest improvements in yield coinciding with greatest improvements in quality. Harvesting too early or too late resulted in lower cooking quality.

Field Peas

Diquat treatments were applied to green-seeded field peas (Pisum sativum L.) over a 5-yr period to determine the effect of applications at various stages of maturity on some agronomic and quality characteristics. The spray application effectively hastened drying of the plants, eliminating the need for windrowing. The rate of 0.28 kg a.i./ha was adequate. The earlier harvesting permitted by the treatments reduced loss of green color and germinability associated with weathering and reduced yield loss from shattering. Applications made as early as the 50% brown pod stage did not markedly affect yield, protein content, seed size, cooking quality or germinability. However, a later stage of spraying may be advisable under conditions of slow maturation.

Effect On Yield

Seed lots of field pea (Pisum sativum L.), varying in cooking quality (viscosity of puree) and protein concentration were grown in the field in 1986 and 1987 to determine the effect of those factors on subsequent yield, cooking quality and protein concentration. Under the conditions of the experiments, cooking quality and protein concentration of the seed had no marked effect on yield, 1000-seed weight, cooking quality or protein concentration of the subsequent crop.
