Crop diversification, with oilseed and pulse crops replacing cereals, is occurring even in the Brown soils of Southwestern Saskatchewan. With diversification comes more agronomic questions, as new management strategies must be developed to cope with problems, such as reduced residue production from non-cereal crops. The use of the 1997 PFRA crop residue and seeding survey data help to establish the link between agricultural diversification and the soil climatic factors influencing this diversification, along with the effects this could have on the sustainability in different regions of Saskatchewan.Item 2002 soil and weed survey conducted on Saskatchewan organic cropland(2003-02-18) Buhler, R.S.; Shirtliffe, S.J.; Knight, J.D.A soil survey and a weed survey were conducted on 5% of the organic farms in Saskatchewan, in the four major agricultural eco-regions in the 2002. Soil tests were taken in April and May prior to planting. Phosphorus levels were deficient in all regions. Nitrogen and sulphur varied between fields but were lowest over all in the boreal transition eco-region. Potassium was high in all regions. The weed surveys were conducted in July on the same fields as the soil survey. The most abundant species was green foxtail (Setaria virids (L.) Beauv.), wild oats was the fourth most abundant and the seventh most abundant species was Canada thistle (Cirsium arvense (L.) Scop.). Annual broad-leaved weeds were the most common weed group in the survey. Buckwheat (Polygonum convolvulus L.), lamb’s quarters (Chenopodium album L.), stinkweed (Thlaspi arvense L.), and wild mustard (Sinapis arvensis L.) were four of the six most abundant weeds in the organic survey. These results are opposite to the trend seen in conventional production where annual broad-leaves have become less abundant according to the surveys conducted from 1976 to 1995 (Thomas, 1996).Item 2003 South East Research Farm Inc. project results update – economic analysis of field scale ‘pesticide-free production™’ of flaxseed(2004-02-19) Briggs, B.R.The flax variety CDC Bethune was grown under two cropping systems. The most common conventional method will be compared to growing flax under the Pesticide Free Production (PFP)™ guidelines. Two PFP™ treatments will be compared to one conventionally grown treatment. Economic analysis will be completed on each of the three treatments to determine if PFP™ is economically viable in field scale production of flaxseed. Average market prices from October 1, 2003 to March 1, 2004 for each system will be used in the analysis. Net yields between each crop were not significant, but final economic analysis will determine differences.Item The 2011 stripe rust epidemic in western Canada(2012-03-13) Kutcher, H.R.; Randhawa, H.S.; Puchalski, B.; Wogsberg, S.; Graf, R.; Gaudet, D.Item 2012 aster yellow outbreak in Saskatchewan(2013-03-06) Olivier, C.Item 2012 weed survey of Saskatchewan canola fields(2013-03-06) Leeson, J.Y.Item 2016 Saskatchewan Insect Update(2016-03-16) Hartley, S.Item 2019 ultra-short season soybean - yield and its components(2020-03-10) Tafesse, Endale Geta; Bueckert, RosalindSoybean (Glycine max L.) is the most widely grown legume crop in the world, and in Saskatchewan soybean success depends on fitting this warm-season crop to a cool, dry and short growing season. In 2019 we grew twenty-four conventional and GMO soybean cultivars (varieties) from industry and breeding programs across four locations (Rosthern, Saskatoon, Outlook (irrigated), and Kamsack) in SK. Our objective was to evaluate yield and its components of Maturity Group 0, 00, and 000 cultivars representing the range of early maturity currently available for western Canada. We found significant variation in plant height, number of main stem nodes, number of branches, main stem pods, branch pods, above-ground biomass, and harvest index (the ratio of grain weight to above-ground biomass). Genotype x environment interaction was mostly non-significant but the four locations significantly varied for all traits. Rosthern had larger plants with more nodes, more branches, greater seed number per area and harvest index. Surprisingly, Kamsack and Saskatoon had lower values for most traits. Tall cultivars with more nodes generally had lower harvest indices. Cultivars with greater seed yield had more branches, and hence more pods. This preliminary study highlights the potential of soybean production under Saskatchewan environments although more years and environments are needed to identify the best adaptation traits.Item 25 years of tillage effects on wheat production in a continuous cropping system(2007-03-01) Wang, H.; McConkey, B.G.; Peru, M.; Brandt, K.Heat stress occurs often in wheat on the Canadian Prairies especially during grain growth (from anthesis to maturity), which has a markedly negative impact on yield (McCaig 1997). Under no-till management (NT), surface residue and stubble act as insulation and impede the exchange rate of thermal energy between the soil and the atmosphere, and the superior soil moisture of NT compared to conventional tillage (CT) can buffer the extremes in daily soil temperatures. It is, therefore, possible that the cooling effect of NT could alleviate the root heat stress of wheat. Under a continuous wheat cropping system on a Thin Black Chernozemic clay loam in central Alberta, Wang et al (2007) found that the near-surface soil temperature of NT was lower than that of CT throughout the growing season, which reduced the risk of root heat stress and benefited grain yield and biomass. The objective of this study was to investigate whether a similar effect of NT is present in southwestern Saskatchewan.Item A 25-year review of fertilizer consumption and plant nutrient removal in the prairie provinces(1992-02-20) Doyle, P.J.; Cowell, L.E.; Rennie, D.A.; Campbell, C.A.Nutrient removal I replacement ratios were calculated in Manitoba, Saskatchewan, and Alberta from 1965 to 1989 by dividing total fertilizer (N, P, and K) sales by the total crop removal of plant nutrients. The nutrient removal I replacement ratios revealed that significant depletions of soil reserves of N, P, and K have taken place over the past 25 years. The average negative balance of N, P2O5, and K2O on the prairies is estimated at 640, 125, and 490 thousand tonnes. Even with the substantial increase in the use of fertilizers in the past five years compared to the 25 year average, the nutrient deficit continues to be unacceptably high for nitrogen (485,000 tonnes), only modest for phosphorus (86,000 tonnes), and as could be expected for potassium, has increased significantly to 570,000 tonnes. Overall, the calculations suggest that Manitoba is very close to nitrogen and phosphorus balance. Alberta has a relatively close balance, while Saskatchewan has not only experienced an unacceptably high N and P deficit for the past 25 years, but continues to do so at the present time.Item The $5.50 per acre experiment(2002-02-20) Karamanos, R.E.; Flaten, D.Item Abscisic acid analogues for enhanced stress tolerance and size control of tomato seedlings(2001-02-22) Sharma, N.; Abrams, S.R.; Waterer, D.Transplanting shock is a common problem during establishment of horticultural crops like vegetables and ornamental bedding plants. The marketing period of nursery raised seedlings is limited due to the loss of aesthetic quality associated with undesirable growth and accelerated moisture loss during storage and handling. Two synthetic analogues (PBI 365 and PBI 429) of the plant hormone abscisic acid (S. Abrams PBI/NRC) were evaluated in a number of greenhouses and field trials at the University of Saskatchewan, for their potential to alter the stress tolerance and growth of horticultural crops. Pre-planting application of analogues, at 10-4 M, enhanced the tomato transplants survival under moisture stress in field conditions. Under greenhouse conditions, the ABA analogues slowed the moisture use and growth of seedlings without deteriorating the visual quality. Thus, ABA analogues could be used in horticultural crops for enhanced stand establishment as well as to hold seedlings at a particular stage thereby allowing their storage and extending the marketing period.Item Abundance and diversity of AM fungal communities associated with agricultural factors(2013-03-05) Dai, M.; Hamel, C.; Gan, Y.Item Accounting of nitrogen levels in Saskatchewan soils(1992-02-20) Karamanos, R.E.; Kruger, G.A.Item Acid soils in west-central Saskatchewan(1981-02-16) Rostad, H.P.W.
