Initial soil nutrient trends of polyculture in long term rotation
Non-Peer ReviewedThis poster reports on an initial trend relating to the use of polycultures and soil fertility. Soil nitrate and phosphorous levels have been monitored in the long term rotations study located at Swift Current where, for the last two years, a 12 species mix (triticale, barley, oats, corn, sorghum, German millet, hairy vetch, field pea, forage pea, forage radish, purple top turnip and kale) has been included in the rotation
The root growth strategies of three wheatgrass in early seedlings
Non-Peer ReviewedResearch was conducted on crested, slender and northern wheatgrasses, commonly available
wheatgrasses for the Canadian prairies, under 6% and 12% of gravimetric water content, to
determine the effect of water stress on root growth for seedling growth. The results indicate
that Root growth rate varies across early seedling phase for these grasses. Rapid root biomass
accumulation occurred in the early phase of seedlings. Reducing water supplement increased
biomass allocated to roots earlier for plant growth. Reduced water treatments demonstrated a
non-linear changed root biomass growth rate for crested wheatgrasses and northern
wheatgrasses
Germination of two native wheatgrass (Agropyron) species under different temperature and water potential regimes
Non-Peer ReviewedNative wheatgrass species are important for land reclamation or rangeland re-seeding. The objective of this study was to evaluate seed germination of slender wheatgrass (Agropyron trachycaulum Link Malte) and northern wheatgrass (Agropyron asystachyum (Hook.) Scribn.) under different temperatures and water potentials. Over a 10 d period, germination was studied in four growth chambers with constant temperatures of 5, 10, 20 and 25°C and water potentials of –1.0, –0.8, –0.6, –0.4, –0.2 and 0.0 Mpa at each temperature. Two wheatgrass species showed a good germination at or higher than –0.4 Mpa water potentials when temperature was 20-25°C, but the percentage was reduced at or lower than –0.6 Mpa. Compared to northern wheatgrass, higher percent of seed germinated for slender wheatgrass at lower water potential, but slender wheatgrass required higher germination temperature

Standardizing vegetative propagation as a tool for polycross mating of ascending purple milkvetch (Astragalus adsurgens Pall.)
Non-Peer ReviewedThis article highlights the efficacy of plant growth regulators and nutrient solutions on root development and survival of ascending purple milkvetch (APMV) cuttings. Three auxin-like growth regulators and Hoagland solutions were used as root inducing agents. The cuttings were planted in sand medium that allowed evaluation of rooting effectiveness. The study showed that up to 100% establishment of APMV cuttings can be achieved with the application of half-strength modified Hoagland (MHL) solution and plant growth regulators such as indole-3-acetic acid (IAA), 1-naphthaleneacetic acid (NAA) and indole-3-butyric acid (IBA) at 100mg L-1 strength. To the best knowledge of the authors, this is first time documentation of the vegetative propagation of APMV
