White prairie clover [Dalea candida (Michx.) Willd.] is native to the dry prairies and hillsides of the Northern Great Plains. A study was initiated in 2012 with six white prairie clover populations collected from the Canadian Prairies. Plant growth characteristics, forage biomass, seed yield, and forage nutritive values were evaluated using a randomized complete block design in a field near Swift Current, SK. Three populations from Argyle, Carlowrie, and Big Grass Marsh (NCP588) in Manitoba displayed erect-type growth while those from Douglas Provincial Park and Stewart Valley in Saskatchewan and Writing on Stone Provincial Park in Alberta exhibited prostrate growth. The populations did not differ for mean biomass yield (79–104 g plant−1, p = 0.54) and mean seed yield (6.6–9.1 g plant−1, p = 0.69); however, they differed for bloom stage nutritional parameters such as acid detergent fibre (25%–30%, p = 0.04), neutral detergent fibre (34%–41%, p < 0.01), crude proteins (15%–18%, p < 0.01), phosphorus (0.24%–0.29%, p = 0.02), and iron content (144–360 ppm, p = 0.01). To our knowledge, this is the first report of comparative phenotypic, nutritional, and propagation study of native white prairie clover populations of Canada. The constraints and opportunities for successful domestication of white prairie clover as a forage crop are discussed.

We compared the growth and yield of five Brassica spp. genotypes [two B.juncea (L.) Coss., two B. napus L. and one B. rapa L.] in 11 environments spanning two degrees of latitude and longitude in southern Saskatchewan in 1996–1998. All entries were managed with three levels of N fertility at each site. Plant height for the canola-quality B. juncea breeding line J904316 was 21% greater than the mean of the other genotypes, but shoot biomass did not differ for the same comparison. Cutlass Oriental mustard consistently yielded greatest across all environments while the yield of J904316 was highly variable among environments. The mean seed yield of Cutlass was 12% greater than the highest-yielding B. napus cultivar and 32% greater than the B. rapa cultivar, and had a greater harvest index. Earlier genotypes yielded greater than late-flowering and maturing genotypes within B. juncea and B. napus, but the earliest genotype, Maverick (B. rapa), yielded lower than all other genotypes. All Brassica spp. genotypes were responsive to N fertilization, and high total available N (average = 109, range = 91 to 131 kg N ha-1) was generally required to maximize seed yield, but not shoot biomass, under the conditions of this study. Pod density was the primary yield component influenced by N level. This study illustrates the potential adaptive advantage of B. juncea on the semiarid northern Great Plains.

The Impact

Tillage is being reduced in semiarid regions. The impact of changing tillage practices on field pea (Pisum sativum L.) performance has not been considered in a major pea-producing area within the US northern Great Plains. A study was conducted from 2000 through 2005 to determine how field pea performance compared following spring wheat (Triticum aestivum L.) in clean-till (CT), reduced-till (RT), and no-till (NT) systems arranged in a randomized complete block at Dickinson in southwestern North Dakota. Seed yield increased over 1600 kg ha-1 in 2000 and almost 400 kg ha-1 in 2003 under NT compared with CT, and by 960 kg ha-1 in 2000 under NT compared with RT (P < 0.05). Differences in seed yield were not detected between tillage systems in other years. Plant establishment was improved as tillage was reduced, averaging 66 plants m-2 under NT and RT compared with 60 plants m-2 under CT management. The soil water conservation that can occur after adopting NT may explain the increased seed yields that occurred in some years. These results suggest that field pea seed yield can be increased by eliminating tillage in semiarid areas of the US northern Great Plains, particularly when dry conditions develop and persist.

Ground Biomass

Chickpea (Cicer arietinum L.) has two kinds of leaf types, the fern and unifoliate. The best leaf type to use for biomass production and yield in the short growing season of the Northern Great Plains, which has a semiarid environment with end of season rainfall, is not yet known. The objectives of this research were to determine the relationships between leaf type and crop growth rate, maximum above-ground biomass, harvest index and yield under moderate and high plant population densities. The study was conducted in the field at Saskatoon and Swift Current, Saskatchewan, in 2003 and 2004. The experimental treatments consisted of a factorial combination of six commercial kabuli chickpea cultivars representing the two leaf types and two plant population densities: 45 and 85 plants m-2. There were no cultivar and plant population interactions for crop growth rate, maximum above-ground biomass, harvest index and seed yield. Dry matter production was higher in the 2004 season, which had above-average rainfall and a longer duration of reproductive growth. Although high plant population exhibited higher maximum above-ground biomass in 3 location-years, plant population did not affect the crop growth rate. The 45 plants m-2 treatment had a higher harvest index than the 85 plants m-2 treatment in 2 location-years, but both population treatments were similar in the other two environments. Yield of chickpea was increased by higher plant population in 1 location-year, but was not affected by plant population in the other location-years. The fern leaf cultivars had a higher crop growth rate over the unifoliate leaf cultivars in 2 location-years and no significant difference in the other environment. Fern-leaf cultivars partitioned more dry matter to seed growth compared with unifoliate cultivars while sustaining similar biomass production as unifoliate cultivars. The use of fern-leaf cultivars in the Northern Great Plains appears to be an opportunity for increasing chickpea yield by its superior harvest index compared with unifoliate leaf cultivars.

Seeding Date

We compared the effects of spring seeding date on stand density, crop growth, seed yield, water-use-efficiency, and grain quality of three pulse crops [chickpea (Cicer arietinum L.), lentil (Lens culinaris Medik.) and pea (Pisum sativum L.)] grown at Scott and Swift Current, SK, during 1993 to 1997. Wheat (Triticum aestivum L. emend. Thell.) was used as a reference crop. Seeding date did not meaningfully affect plant density for chickpea, lentil or pea. Crop growth stage related to thermal time resulted in robust prediction equations for chickpea, lentil and pea (R2 = 0.87 to 0.98). When seeding was delayed 2 wk, the crop response was inconsistent. When seeding was delayed by 4 wk, consistent, mainly negative, effects on crop parameters occurred due to the exacerbation of summer drought stress. Pulse crop yields were more negatively affected by delayed seeding than were wheat yields. When seeding of chickpea, lentil, and pea was delayed 4 wk, seed yield decreased at the majority of site-years. When yield reductions occurred, the average reductions were 44, 38, and 31%, for the respective species. For chickpea and lentil, seeding delays of 2 and 4 wk decreased seed size at the majority of site-years with seed size reductions averaging 10% when they occurred. In the semiarid Northern Great Plains (NGP), chickpea, lentil, and pea should be seeded before spring wheat due to a greater risk of loss of yield and quality.

Camelina (Camelina sativa L. Crantz,) a new oilseed crop in the Brassicaceae family has favorable agronomic traits and multiple food and industrial uses. Appropriate production practices for optimal camelina yield in temperate climates of North America are lacking. This study investigated the response of camelina seed yield and quality, and agronomic traits to applied N (5 levels, 0, 28, 56, 84, 140 kg ha−1) and four seeding rates (4.5, 9, 13, 17.5 kg ha−1). Separate experiments were conducted at four environments (site-years) for N and three environments for seeding rate in South Dakota. In three of the four environments, the highest N rate increased seed yield by 30 to 60% compared to the control. The increase in seed yield with increasing N rate was linear in a high yielding environment and quadratic in a low yielding environment. Increasing seeding rate increased plant stands but had inconsistent impacts on seed yield depending on location and year. Seed oil concentration ranged from 149 to 350 g kg−1, was inversely related to N rate but was not influenced by seeding rate.
