2020 Organic Spring Wheat Crosses Variety Trial, Heather Darby, Henry Blair
2020 Organic Spring Wheat Crosses Variety Trial, Heather Darby, Henry Blair
Northwest Crops & Soils Program
The goal of this project is to develop new spring wheat varieties that are suited for organic management in Northeast soils and climatic conditions. Most commercially available varieties are developed in regions with climates, soils, and management techniques that are very different from northern New England. These modern varieties are also genetically homogenous and inbred for uniformity, sometimes resulting in rapid breakdown of genetic resistance to local diseases. Eight crosses were developed by Dr. Stephen Jones of Washington State University, including crosses of two varieties bred by famed Vermont botanist and wheat breeder Cyrus Pringle. Of these varieties, a number …
The Efficacy Of Spraying Organic Fungicides To Control Fusarium Head Blight Infection In Spring Wheat, Heather Darby, Hillary Emick, Haley Jean
The Efficacy Of Spraying Organic Fungicides To Control Fusarium Head Blight Infection In Spring Wheat, Heather Darby, Hillary Emick, Haley Jean
Northwest Crops & Soils Program
Locally grown grains, such as wheat and barley, are in high demand in the Northeast for both livestock feed and human consumption. Many bakeries feature loaves baked with locally grown wheat. Hard red spring wheat is most commonly used for bread flour. One major challenge that grain growers encounter is infection by disease-causing fungi, such as the fungus Fusarium graminearum, whose spores can infect plants from flowering until grain fill. Fusarium head blight (FHB) can shrivel grain, decrease seed germination, decrease yields, and contaminate grains with mycotoxins. The primary mycotoxin associated with FHB is deoxynivalenol (DON), a vomitoxin. If …

Organic Spring Wheat Variety Trial, Heather Darby, Rory Malone, Hillary Emick, Haley Jean, Ivy Krezinski
Northwest Crops & Soils Program
In 2019, the University of Vermont Extension Northwest Crops and Soils Program evaluated thirty-five hard red spring wheat varieties to determine which would thrive in the Northeast. The trial was established at the Borderview Research Farm in Alburgh, Vermont. Varieties that did not perform well in previous years were eliminated from the 2019 trial and new varieties were added.

Department of Agronomy and Horticulture: Faculty Publications
Developing genomic selection (GS) models is an important step in applying GS to accelerate the rate of genetic gain in grain yield in plant breeding. In this study, seven genomic prediction models under two cross-validation (CV) scenarios were tested on 287 advanced elite spring wheat lines phenotyped for grain yield (GY), thousand-grain weight (GW), grain number (GN), and thermal time for flowering (TTF) in 18 international environments (year-location combinations) in major wheat-producing countries in 2010 and 2011. Prediction models with genomic and pedigree information included main effects and interaction with environments. Two random CV schemes were applied to predict a …

Small Grains And Field Peas: 2009 Variety Recommendations (2008 Crop Performance Results), Cooperative Extension Service, South Dakota State University
SDSU Extension Circulars
Variety selection is a fundamental element in a sound crop production program. This report contains variety recommendations, descriptions, and yield data for the spring-seeded small grains – hard red spring wheat, oat, and barley, along with the fall-seeded small grain –hard red winter wheat. Key factors in variety selection include yield, yield stability, maturity, straw strength, height, test weight, quality, and disease resistance. Yield is an important factor; however, a variety with good disease resistance, straw strength, and high grain quality may be more profitable in some cases than the highest yielding variety. Disease resistance information is based on reactions …

Diversified Cropping Systems In Semiarid Montana: Nitrogen Use During Drought, Andrew W. Lenssen, J. T. Waddell, G. D. Johnson, G. R. Carlson
Andrew W. Lenssen
Improved nitrogen use efficiency would be beneficial to agroecosystem sustainability in the northern Great Plains of the USA. The most common rotation in the northern Great Plains is fallow–spring wheat. Tillage during fallow periods controls weeds, which otherwise would use substantial amounts of water and available nitrogen, decreasing the efficiency of fallow. Chemical fallow and zero tillage systems improve soil water conservation, and may improve nitrogen availability to subsequent crops. We conducted a field trial from 1998 through 2003 comparing nitrogen uptake and nitrogen use efficiency of crops in nine rotations under two tillage systems, conventional and no-till. All rotations …

Changes In Weed Response To 2,4-D Application With 5 Repeated Applications In Spring Wheat, Hüseyi̇n Zengi̇n
Changes In Weed Response To 2,4-D Application With 5 Repeated Applications In Spring Wheat, Hüseyi̇n Zengi̇n
Turkish Journal of Agriculture and Forestry
2,4-D amine and 2,4-D isooctylester were sprayed repeatedly in the spring of 5 consecutive years on spring wheat (Triticum aestivum L.cv.Kırik)in Erzurum during the years 1990-1994. The herbicide efficacy against all broad-leaved weeds and against the most common weed species was determined by comparing the number of weeds in untreated and treated plots. The most abundant weed species were Polygonum aviculare, Amaranthus retroflexus and Chenopodium albumin spring wheat. The effect of 2,4-D amine decreased after 3 or 4 years in A.retroflexus, C.album,Convolvulus arvensis, Acroptilon repens, Lactuca serriola, P.aviculare, Cirsium arvense and other broad-leaved weeds. Effects against Sinapis arvensis and Sisymbrium …

Tests indicate which varieties of oats, barley and spring wheat are best adapted to Nebraska growing conditions. The primary spring small grain grown in Nebraska is oats. Oats are grown throughout the state, but production is concentrated in the east and northeast cropping districts. Nebraska's estimated harvested oat acreage in 1989 was 310,000 acres. Spring barley production is centered in the northwest and southwest districts. Harvested barley acreage in 1990 was 30,000 acres. Barley is commonly grown as an early summer feed grain and corn substitute. Spring wheat production in Nebraska is concentrated in the northern section of the state …

University of Nebraska-Lincoln Extension: Historical Materials
Herbicides recommended for postemergence application in corn, sorghum, and small grains are discussed in this NebGuide. Proper timing of postemergence herbicides is essential to achieve maximum weed control and minimum crop injury. As field crops grow and mature, their tolerance to herbicides changes. As a general rule, annual and biennial weeds are more susceptible to postemergence herbicides when they are in the seedling stage. As they mature they become increasingly difficult to control, facing the grower with the problem of when to apply the herbicide to achieve the least crop injury and the most satisfactory weed control. Field crops differ …

The Fourth International Winter Wheat Performance Nursery was grown in 1972 at 44 sites in 27 countries. Data were reported from 40 sites. The 30 cultivars grown in the nursery included 15 new entries. Twenty-nine cultivars were winter wheats; one was a spring wheat. Data are reported on grain yield, test weight, plant maturity, plant height, lodging, shattering, winter survival, 1000 kernel weight, frost damage, plant diseases, grain protein and lysine content. Two-year mean data summaries also are reported. Supplemental nursery management information is reported for each nursery site.
