“…With swath grazing, the effort required for livestock to access winter forage is reduced, allowing livestock access to biomass and grain, even in deep snow. There have been numerous advances in swath grazing with the development of forage cultivars suited for frigid climates (McGeough et al, 2017). Autumn interseeding techniques have enabled small grains to be seeded and grazed following fall harvest of the primary crop (AAFC, 2017; McLelland and Brook, 2018).…”

Integrated crop–livestock systems (ICLSs) can help increase food production while benefiting soils and the environment. This review summarizes recent impacts of ICLSs on crop and livestock production and rural economics and discusses lessons learned in the northern Great Plains (NGP). Research on ICLS conducted in the NGP indicates that the crop residue grazing, swath grazing, and annual forage grazing can positively influence crop production; whereas, livestock performance varies with season, forage nutritive value, and grazing management. Furthermore, ICLSs can reduce the costs and risks of agricultural production. The success of ICLSs in NGP region depends on trade‐offs, planning, economic benefits, policies, regulations, community acceptance, and management skills. The ICLSs could play a strategic role in future agricultural production. The lessons learned from adopting ICLSs in the NGP include the lack of available land for fertilizer (manure) management, that to implement ICLS practices skills and knowledge must be maintained, and ICLS provides an entry point for young farmers and ranchers however capital is needed. These experiences and lessons could be valuable references for producers to adopt ICLSs in the NGP or other regions. Core Ideas Integrated crop–livestock systems positively affect crop production by improving soil health. Common integrated crop–livestock system management techniques can enhance the northern Great Plains crop production. Integrated crop–livestock system livestock performance is impacted by season, forage selection, and management. Integrated crop–livestock systems can increase economic benefits and reduce economic risks. Experiences and lessons in the northern Great Plains could be valuable for other regions to adopt integrated crop–livestock systems.

“…Table 5 shows a forage quality comparison of stockpiled intermediate wheatgrass between two renovation treatments. The first treatment was clipping to 5 cm and 60 kg ha Other issues that may become important will include the potential for reduced perenniality as harvest index increases (Zhang and Jiang 2000;Smaje 2015;González-Paleo et al 2016), the continuity of productivity (Cattani 2017) and pest infestations as area planted increases.…”

Production agriculture relies primarily on seeding of annual crops for food, feed, fuel and fibre in western Canada. Annual seeding and harvesting commonly leave land non-productive for a portion of the year. There is the potential for both soil and nutrient loss from this unused land base, and as important, we are missing the potential for photosynthesis. Capture of carbon in these off-season times may aid in carbon sequestration. Forage production (feed) relies on an animal market for its consumption. Forage seed production in Canada, accounts for approximately 65,000 ha year -1 , and is almost exclusively located in western Canada. It is unlikely however that forage seed production area will dramatically increase due to limited markets. Perennial grains could greatly increase the land area dedicated to perennial seed production and provide alternative markets to forage products and forage seed. Intermediate wheatgrass (Thinopyrum intermedium (Host) Bark. & Dewey) (Kernza TM ) is the perennial grain closest to release and some potential niche markets are currently emerging. Improvement has been made through selection for grain production on individual plants for characteristics that are likely of importance at field scale production. Agronomic packages for intermediate wheatgrass production are lacking, although forage seed production agronomy will guide this development.Agronomic benefits attributed both to perennial seed production and the inclusion of perennials in cropping systems will be greatly enhanced when the potential for perennial grain production (breeding and agronomy) is realized.Key Words: forage seed, perennial grains, agronomy, perennial crop cycle. The IssueAnnual production agriculture does not take full advantage of the opportunity to capture the solar energy during the growing season in the temperate areas of western Canada.Planting annuals in the spring after the threat of killing frosts have passed is standard for most crops, with winter annuals being an obvious exception (see Larsen et al., this issue). The land area is either left as is post-harvest (e.g. for zero-till establishment or spring tillage) or is subjected to mechanical disturbance. While this disturbance can have agronomic benefits such as aiding in the fall germination of seed that escaped harvest and in seedbank depletion (Geddes and Gulden 2017), it leaves the area susceptible to both nutrient loss and soil erosion.In most of Canada much of the early and late season solar energy is not, or is grossly under-utilized on agricultural land. For example, at the University of Manitoba Ian N. MorrisonResearch Farm at Carman MB, there were 65.7, 26.6, 84.3, 184.4, and 128.9 accumulated growing degrees day (GDD), base T 0°C, in April for the years 2012-2016, respectively (Table 1). This is in general below the 1991-2010 20-year average. September has had a higher than average GDD accumulation in the years 2012-2016 and rainfall has been above average for three of the past five years (Table 1). October has also had highe...

“…Biligetu et al [34] showed that ALF with WWG or RWR had higher CP level, consistent with the current study. In contrast, McGeough et al [56] stated that CWG, MBG, WWG, northern wheatgrass, and green needlegrass in mixture with ALF showed low protein levels ranging from 5.0 to 10.7%, suggesting advanced plant maturity. All binary mixtures at both sites had similar TDN concentration, meeting beef cow nutrient requirements (440.9 to 640.5 g kg −1 ) [54].…”

The potential for novel forage mixtures to address reduced herbage for late season grazing was investigated. Forage legumes, sainfoin (Onobrychis viciifolia Scop.) (SF) cvs. AC Mountainview, Shoshone, and Nova (MountainSF, ShoshoneSF, and NovaSF), cicer milkvetch (Astragalus cicer L.) cv. AC Veldt (CMV), Canadian milkvetch (Astragalus canadensis L.) cv. Great Plains (CaMV), and alfalfa (Medicago sativa L.) cv. AC Yellowhead (ALF) were evaluated in binary mixtures with meadow bromegrass (Bromus riparius Rehm.) cv. Admiral (MBG), hybrid bromegrass (B. riparius × B. inermis Leyss.) cv. AC Success (HBG) and Russian wildrye [Psathyrostachys junceus (Fisch.) Nevski.] cv. Tom (RWR) for yield, botanical composition, and nutritive value on July and September harvest dates at Saskatoon and Swift Current, Saskatchewan, Canada from 2016 to 2018. Hybrid bromegrass-legume mixture produced 16–38% greater forage compared to RWR-legume (7.5 vs. 5.6 Mg ha−1 in July and 6.1 vs. 5.1 Mg ha−1 in September at Saskatoon, and 3.2 vs. 2.0 Mg ha−1 in July at Swift Current). MountainSF and ALF had the greatest legume contribution to total yield at July harvest at Swift Current (67.7 ± 3.2%) and Saskatoon (62.1 ± 2.1%), respectively, while CaMV had lowest composition at Swift Current (20.2 ± 2.5%) and Saskatoon (12.6 ± 3.5%). The CMV and ALF-grass mixtures at Saskatoon and legume-RWR mixtures at both sites in July had greatest CP content. The July harvest had greatest yield, legume content and nutritive value compared to the September harvest at both sites. Study results suggest if yield is the objective, then either ALF or CMV with HBG may be considered. If nutritive value is the goal, any legume with RWR is an option. Finally, ALF or CMV in mixture with either HBG or RWR could be summer or fall stockpile forage in the Northern Great Plains of western Canada.
