2021 Western Australian Crop Sowing Guide, Brenda Shackley, Blakely Paynter, Jackie Bucat, Georgina Troup, Mark Seymour, Andrew Blake

Bulletins 4000 -

This edition of the 2021 Crop Sowing Guide includes the major crops grown in WA - wheat, barley, canola, oat, lupins and pulses. The publication aims to provide information to support growers with decisions on the best choice of variety for each of the major crops for the upcoming season. The lupin and pulse sections also include an agronomy guide summary to support management decisions required for these high-valued crops. Market feedback for barley has been provided by GIWA to help with the decision on what to grow.

Coal Char Affects Soil Ph To Reduce Ammonia Volatilization From Sandy Loam Soil, Dinesh Panday, Maysoon M. Mikha, Bijesh Maharjan

Department of Agronomy and Horticulture: Faculty Publications

Ammonia (NH₃) volatilization loss adversely affects N availability in soil-plant systems, reduces crop yield, and negatively impacts environment. Char (coal combustion residue), which contains up to 293 g kg⁻¹ total C by weight, has been shown to reduce NH₃ volatilization due to its considerably high surface area and cation exchange capacity. The NH₃ loss can be greatly affected by a shift in soil pH or urea hydrolysis. A 21-d laboratory study was conducted to evaluate the effects of char on soil pH, N transformations, and subsequent NH₃ volatilization in sandy loam soil. Two …

Grains, Seeds And Hay Industry Funding Scheme Annual Report 2019/2020, Department Of Primary Industries And Regional Development, Western Australia

Biosecurity published reports

The Grains, Seeds and Hay Industry Funding Scheme (IFS) has been operating since 2010 to address biosecurity threats relevant to Western Australia’s (WA) grains, seeds and hay industry. The Scheme was established under the Biosecurity and Agriculture Management Act 2007 to enable growers to identify the pest and disease priorities at a whole-of-industry level and raise funds for activities to address these priorities.

There are currently three Industry Funding Schemes in operation. In addition to the Grains, Seeds and Hay IFS, there is a Cattle IFS and a Sheep and Goat IFS. The three IFSs operate in a similar manner. …

Breeding Alfalfa For Semiarid Regions In The Northern Great Plains: History And Additional Genetic Evaluations Of Novel Germplasm, Arvid A. Boe, Kevin D. Kephart, John D. Berdahl, Mike D. Peel, E. Charles Brummer, Lan Xu, Yajun Wu

Natural Resource Management Faculty Publications

Yellow-flowered alfalfa (Medicago sativa subsp. falcata) (also known as sickle medic) has been the cornerstone for breeding alfalfa for dual grazing and hay production in the semiarid regions of the northern Great Plains in the US and Canada. Most, if not all, of the cultivars developed for the northern Great Plains during the 20th century, had parentage tracing back to introductions by Niels Ebbesen Hansen that were obtained from expeditions to Russia, primarily the province of Siberia, on behalf of the United States Department of Agriculture during the early 1900s. The M. falcata genome contains alleles for high levels of …

The Role Of Quality Characteristics In Pricing Hard Red Winter Wheat, Shane J. Roberts

Department of Agricultural Economics: Dissertations, Theses, and Student Research

In this thesis, we empirically examine the role of conventional and end-use wheat quality characteristics on the pricing of hard red winter wheat (HRWW). We use detailed quality characteristic data as well as location matched price data for 50% and 100% harvest completion weeks and utilize a hedonic price analysis framework. We find evidence that end-use characteristics, specifically milling and baking quality characteristics, have a statistically and economically significant effect on the price of HRWW. This evidence suggests that, while HRWW producers are not directly paid premiums or discounts for end-use quality, they are paid indirectly through basis. Comparing results …

Weather And Soil In The Us Midwest Influence The Effectiveness Of Single-And Split-Nitrogen Applications In Corn Production, Jason Clark, Fabian G. Fernandez, James J. Camberato, Paul R. Carter, Richard B. Ferguson, David W. Franzen, Newell R. Kitchen, Carrie A.M. Laboski, Emerson D. Nafziger, John E. Sawyer, John F. Shanahan

Agronomy, Horticulture and Plant Science Faculty Publications

Splitting the N application into two or more timings may improve corn (Zea mays L.) grain yield and N recovery relative to a single-N application. A 49 site-year study across eight U.S. Midwestern states compared the effect of an at-planting (single-N application) and two split-N applications [45 (45+SD) or 90 kg N ha−1 (90+SD) at planting with the remainder of the total rate (180 or 270 kg N ha−1) applied at V9]. For split-N applications, soil and plant responses were similar between 45+SD and 90+SD 93–98% of the time, indicating the at-planting N rate of 45 kg N ha−1 may …

Economics Of Herbicide Programs For Weed Control In Conventional, Glufosinate, And Dicamba/Glyphosate-Resistant Soybean Across Nebraska, Adam M. Striegel, Kent M. Eskridge, Nevin C. Lawrence, Stevan Knezevic, Greg R. Kruger, Christopher A. Proctor, Gary Hein, Amit J. Jhala

Department of Agronomy and Horticulture: Faculty Publications

Despite widespread adoption of dicamba/glyphosate-resistant (DGR) soybean [Glycine max (L.) Merr.] in Nebraska and across the United States in recent years, economic information comparing herbicide programs with glufosinate-resistant (GLU-R) and conventional soybean is not available. The objectives of this study were to evaluate weed control efficacy, crop safety, gross profit margin, and benefit/cost ratios of herbicide programs with multiple sites of action in DGR, GLUR, and conventional soybean. Field experiments were conducted in 2018 and 2019 at three irrigated and two rain-fed locations across Nebraska, for a total of 10 site-years. Herbicides applied pre-emergence (PRE) that included herbicides with …

Identification Of Quantitative Trait Loci Associated With Canopy Temperature In Soybean, Sumandeep Kaur Bazzer, Larry C. Purcell

Crop, Soil and Environmental Sciences Faculty Publications and Presentations

A consistent risk for soybean (Glycine max L.) production is the impact of drought on growth and yield. Canopy temperature (CT) is an indirect measure of transpiration rate and stomatal conductance and may be valuable in distinguishing differences among genotypes in response to drought. The objective of this study was to map quantitative trait loci (QTLs) associated with CT using thermal infrared imaging in a population of recombinant inbred lines developed from a cross between KS4895 and Jackson. Heritability of CT was 35% when estimated across environments. QTL analysis identified 11 loci for CT distributed on eight chromosomes that …
