Proximate And Mineral Composition

Field pea seeds from 10 cultivars grown at two locations in Manitoba in 1986 and 1987 were analyzed for proximate and mineral profiles. Cultivars differed significantly in their level of total protein, crude fat, ADF, and all minerals tested. However, differences were not extremely large and were comparable to European reports. Location-year also had a significant effect on the levels of total protein, ADF, and all minerals tested. In most cases, the warmest location-year produced relatively higher levels of minerals, ash, and total protein, and lower seed yield than the coolest location-year.

Natural Enrichment

Pulses are important dietary sources of selenium (Se). Supplying needed Se through widely used foods such as pulses and cereals could increase dietary Se intake. We analyzed the total Se concentration of 17 field pea (Pisum sativum L.) cultivars grown at six locations for 2 yr in Saskatchewan. A significant effect of location was identified, with the highest Se concentration in pea seeds grown in the Saskatoon region and the lowest concentration in the Melfort region. The effect of crop year was not significant. Significant genotypic differences in total Se concentration among the 17 field pea cultivars were not observed in the combined analysis. Total Se concentrations over six locations × 2 yr ranged from 373 to 519 µg kg-1, corresponding to 68-94% of the recommended daily allowance (RDA) for adults based on a 100 g serving of dry field peas. Saskatchewan soils are derived from marine shale and are rich in Se, and pulses grown in Saskatchewan have the potential to provide an excellent natural source of this element.

The use of fungicides for the control of ascochyta blight in field pea was investigated. Four fungicides were applied to the cultivars AC Tamor and Radley at two locations in Manitoba in 1993 and 1994. Fungicides were applied either once, twice, or three times at 10-d intervals, beginning at the initiation of flowering. Chlorothalonil and benomyl were effective m reducing the severity of ascochyta blight and increasing the yield and seed weight of field pea. The triple application of chlorothalonil resulted in a mean yield increase of 33% over that of the untreated control. Iprodione and propiconazole were relatively ineffective in controlling ascochyta blight. The percentage of seedborne ascochyta was not significantly affected by fungicide treatments. The severity of ascochyta blight was greater in 1993 that in 1994, resulting in greater benefits of chlorothalonil and benomyl applications in 1993.

Victoria, a yellow-cotyledon field pea (Pisum sativum L.) cultivar, was licensed in April 1984, will be released to growers in 1986. Victoria is well-adapted to most areas of the Maritime Region, where it outyielded the check cultivars in Regional Cooperative Trials conducted from 1981 to 1983.Key words: Cultivar description, pea (field), Pisum sativum L.

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.

Simazine [2-chloro-4,6-bis(ethylamino)-s-triazine] was applied at rates of 0.002–0.800 kg a.i./ha to field peas (Pisum sativum L.) as soil and as foliar applications for 4 yr. Band applications to the soil surface over the seeded rows and incorporated beside the seeded rows in a clay soil had no effect on seed yield or protein content. However, seed yield was increased 25% in the year that seeding was early (3 May) in a fine sandy clay loam, and seed placed into the center of a band into which simazine at 0.4 kg a.i./ha had been rototilled to a depth of 10–12 cm. There were no differences in weight per seed or protein content. Foliar applications were not effective.

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.
