Adaptability and Quality of Winter Pea and Lentil in Alberta

Abstract

It is unknown if winter pea (Pisum sativum L.) and winter lentil (Lens culinaris Medik.) are feasible cropping options in Alberta. Field experiments were conducted at six locations in southern and central Alberta, Canada, between 2008 and 2012, to determine the adaptability of winter pea and lentil. Two winter pea cultivars, Specter and Windham, and one winter lentil cultivar, Morton, were seeded at three fall planting dates and three seeding rates. Spring cultivars were grown for comparison. In southern Alberta, winter pea and lentil yielded up to 39% more than spring types. The highest winter pea yield was achieved when planting was completed during the first 3 wk of September. The highest winter lentil yield was achieved when planting was completed in the second and third weeks of September. Seeding rate had little or no impact on yield; therefore, winter pea should be seeded at 75 plants m−2 and winter lentil at 110 plants m−2. Seed was analyzed to compare constituent parameters. There were minor differences in the composition of winter and spring pulses. Windham had lower starch but higher resistant starch, protein, crude fat, and ash content compared with spring pea cultivars. Specter had higher resistant starch but was similar to Cutlass for all other parameters. Morton had a higher starch content than CDC Redberry; however, starch quality was similar. Winter pulses have potential to create new and profitable opportunities for growers in the Bow Island and Lethbridge areas of southern Alberta.

Dry pea (Pisum sativum L.) protein, starch, and ash concentrations as affected by cultivar and environment

“…Please refer to Table 1 for environmental codes. study are in agreement with previous findings (Anthony et al 2012;Hood-Niefer et al 2012;Strydhorst et al 2015). A similar study showed that the protein concentration of dry pea ranged from 13.7% to 30.7% for samples collected from a different part of the world (Tzitzikas et al 2006).…”

“…In contrast with starch concentration, considering the mean ash concentration for each location, a positive correlation was observed between ash concentration and the elevation of the testing locations. The mean ash concentrations reported in this study are generally less (only ranged up to 27.7 g kg −1 ) than the results reported by Strydhorst et al (2015) that ranged up to 34.5 g kg −1 for different cultivars and locations. These variations in ash concentration could be attributed to the differences in environments and genotypes used in the two studies.…”

“…These variations in ash concentration could be attributed to the differences in environments and genotypes used in the two studies. Our results are entirely from spring dry pea cultivars, but the results from Strydhorst et al (2015) included means from spring and winter pea cultivars. Winter cultivars are usually planted in fall and have a longer growing period, and therefore could accumulate more minerals in their grain than spring cultivars, which have a short growing period.…”

Variation in Yield, Starch, and Protein of Dry Pea Grown Across Montana

“…Variable contents of RS among different genotypes of rice (Chiu and Stewart, 2012) and wheat (Hazard et al, 2012) have been reported. Strydhorst et al (2015) found winter pea (cultivar Windham) had lower starch but higher resistant starch and protein than spring pea cultivars. However, research is needed regarding the variation of RS and protein among dry pea cultivars growing in different environments.…”

Winter Pea: Promising New Crop for Washington's Dryland Wheat-Fallow Region

“…Chen et al (2006) found that WP cultivars did not have a yield advantage over spring pea in central and south-central Montana. Similarly Strydhorst et al (2015) recommended that farmers consider WP over spring pea only in the southernmost locations in Alberta. Although edible dry pea was harvested on 206,000 ha in Montana in 2016(NASS, 2017 only about one percent of this was WP (P.R.…”
