Farmer-Directed On-Farm Experimentation Examining The Impact Of Companion Planting Barley And Oats On Timothy-Lucerne Forage Establishment In Central Newfoundland, D. Spaner, A. G. Todd

IGC Proceedings (1997-2023)

Growing barley or oats in the year of forage establishment is a common agronomic practice in marginal growing regions, but is often not recommended to growers in Newfoundland. Spaner & Todd (2003) reported that barley seeded at rates of 100-150 kg seed/ha and undersown with a timothy-clover mixture (harvested at mid-milk) resulted in the planting year in greater forage yield of poorer quality than pure-stand timothy-clover. A barley seeding rate of 100 kg seed/ha did not impede forage production in the subsequent year.

Whole Crop Cereal Silage In Dairy Production, J. Wallsten, L. Ericson, K. Martinsson

IGC Proceedings (1997-2023)

Whole-crop cereal silages (WCCS) are used to some extent in Sweden, but knowledge about the use of this feed for high yielding dairy cows is scarce. The crop is often harvested at different stages of maturity, from heading to yellow ripeness, which gives forages that differ in chemical composition. The purpose of this trial was to compare intake and milk production of dairy cows fed a WCCS based on barley harvested at three different stages of maturity.

Use Of Silage Additives In Ensiling Of Whole-Crop Barley And Wheat - A Comparison Of Round Big Bales And Precision Chopped Silages, M. Knický, P. Lingvall

IGC Proceedings (1997-2023)

An increasing use of whole-crop cereals, as supplementary feed, has increased interest in development of efficient ways of preserving these forages to achieve a high hygienic quality. It is known that ensiling of whole-cereals often results in silages with high concentrations of butyric acid (Weissbach & Haacker, 1988). Furthermore, problems with poor aerobic stability still persist despite the use of lactic acid bacteria (Filya et al., 2000). Therefore, the objective of this study was to examine the effect of different types of additive mixtures on the fermentation process and aerobic stability of precision chopped and baled silages.

Pea-Barley Bi-Crop Silage In Milk Production, M. Tuori, P. Pursiainen, A. -R. Leinonen, V. Karp

IGC Proceedings (1997-2023)

Whole crop silage (WCS) from barley or wheat has many advantages as roughage feed. The possibility to use the same harvest machinery as in harvesting grass reduces investment costs. The farms which are specialised in grass production may have shortage of open field area for manure spreading, in which case WCS can be the answer. However, digestibility and protein content of WCS is usually lower than in grass silage, which is limiting the feed intake and performance of the dairy cows. Cultivation of grains with grain legumes increases digestibility and protein content of the stand (Lunnan, 1988). Feeding of bi-crop …

Turkish Journal of Botany

The aim of the present study was to examine the diversity for heat tolerance in a set of 105 accessions using some key morphophysiological attributes. The data was standardized by calculating percent change over control, and used for phonetic analysis and construction of dendograms based on distance matrix (all primary data is given as supplementary material listed in statistical analysis section of Materials and Methods). These distance matrices were then used for the unweighted pair group method with arithmetic mean (UPGMA) cluster analysis using the sequential agglomerative hierarchical nonoverlapping (SAHN) method. The cluster analysis indicated some potential attributes that could …

Assure Ii Alone And With Tacoma And Classic For Efficacy In Fallow, R. S. Currie, P. W. Geier

Kansas Agricultural Experiment Station Research Reports

The objective of this trial was to compare Assure II (quizalofop) at two rates with or without tank mix partners for grass control in fallow. Assure II at either rate alone provided similar control of volunteer corn and barley. Corn control was 90% or more regardless of rating date with all herbicides except Assure II at 8.0 oz/a plus Classic (chlorimuron) at 42 days after treatment (DAT). Tacoma (fenoxaprop) at 3.5 or 5.4 oz/a added to Assure II at 8.0 oz/a improved barley control later in the season.

Climate changes leading to higher summer temperatures can adversely affect cool season crops like spring barley. In the Upper Midwest region of the United States, one option for escaping this stress factor is to plant winter or facultative type cultivars in the autumn and then harvest in early summer before the onset of high-temperature stress. However, the major challenge in breeding such cultivars is incorporating sufficient winter hardiness to survive the extremely low temperatures that commonly occur in this production region. To broaden the genetic base for winter hardiness in the University of Minnesota breeding program, 2,214 accessions from the …

Carry-Over Effect In Forage Rotations On Newly Reclaimed Sandy Soil In Egypt, Z. Abdelhalim, O. Niemeläinen, I. A. Hanna, A. M. Rammah

IGC Proceedings (1997-2023)

This study was carried out to investigate the carry-over effect of a preceding crop on the productivity of the following crop in various rotations in newly reclaimed lands in Egypt. The productivity of peanut (Arachis hypogaea L.), soyabean (Glycine max (L.) Merr.), maize (Zea mays L.) and pearl millet (Pennisetum glaucum (L.) R. Br.) in summer season were much higher following berseem (Trifolium alexandrinum L.) or lentil (Lens culinaris Medic) than after wheat (Triticum aestivum L.) or barley (Hordeum vulgare L.) in both years of the study. Soyabean was the best summer …

Berseem Clover In Binary Mixtures With Oats, Triticale Or Barley For Silage And Late Season Grazing, S. M. Ross, J. R. King

IGC Proceedings (1997-2023)

An experiment was conducted at northerly latitudes with berseem clover (Trifolium alexandrinum L) in binary mixtures with oats (Avena sativa L.), barley (Hordeum vulgare L.) and triticale (X Triticosecale Wittmack). The effects of cereal species, variety and density were assessed for a two cut harvest. Total dry matter yields were 11.7 to 14.5 t ha^-1, with 7.8 to 10.2 t ha^-1 as silage, and 2.0 to 6.0 t ha^-1 as berseem regrowth. Berseem regrowth added an average of 4.0 t ha^-1 in forage yield. Total yields did not differ with cereal …

Coleoptile Length Comparison Of Three Winter Small Grain Cereals Adapted To The Great Plains, M. Alam, M. Kashif, Amanda Easterly, F. Wang, J. D. Boehm Jr., P. Stephen Baenziger

Department of Agronomy and Horticulture: Faculty Publications

Successful crop stand establishment is critical to realize high yield potential, which is dependent on depth of seed placement to access soil moisture. The coleoptile determines sowing depth by its length and ability to emerge from depth. This study was conducted to assess coleoptile length among three sets of three Great Plains winter small grain cereals—wheat (Triticum aestivum L.), barley (Hordeum vulgare L.) and triticale (X triticosecale Wittm.)—and to evaluate the effect of the Rht-B1b dwarfing allele on coleoptile length in wheat and triticale. Fifty seeds of each genotype were sown in wet germination paper in two …

High Plains Wheat Mosaic Virus: An Enigmatic Disease Of Wheat And Corn Causing The High Plains Disease, Satyanarayana Tatineni, Gary Hein

Department of Entomology: Faculty Publications

Brief history: In 1993, severe mosaic and necrosis symptoms were observed on corn (maize) and wheat from several Great Plains states of the USA. Based on the geographical location of infections, the disease was named High Plains disease and the causal agent was tentatively named High Plains virus. Subsequently, researchers renamed this virus as maize red stripe virus and wheat mosaic virus to represent the host and symptom phenotype of the virus. After sequencing the genome of the pathogen, the causal agent of High Plains disease was officially named as High Plains wheat mosaic virus. Hence, High Plains virus, …

Date Of Planting And Nitrogen Management For Malt Barley Production In The Northeast Usa, Arthur Siller, Masoud Hashemi, Alexandra Smychkovich, Caroline Wise, Heather Darby

Data and Datasets

There is an increasing market for locally grown malting barley (Hordeum vulgare L.) in the Northeast US. Malting barley must meet certain quality standards for acceptability in the brewing market. Up-to-date recommendations are needed regionally for adaptation to ongoing climate change. A two-year field experiment was conducted to assess the interactive influence of three dates of planting (5 Sept., 15 Sept, and 25 Sept.), two levels of fall N (0 or 28 kg ha^-1), and three levels of spring N (28, 50.5, and 73 kg ha^-1). No significant difference was detected in grain yield amongst …

Perspectives On Low Temperature Tolerance And Vernalization Sensitivity In Barley: Prospects For Facultative Growth Habit, Maria Munoz-Amatriain, Javier Hernandez, Dustin Herb, P Stephen Baenziger, Anne Marie Bochard, Flavio Capettini, Ana Casas, Alfonso Cuesta-Marcos, Claus Einfeldt, Scott Fisk, Amelie Genty, Laura Helgerson, Markus Herz, Gongshe Hu, Ernesto Igartua, Ildiko Karsai, Toshiki Nakamura, Kazuhiro Sato, Kevin Smith, Eric Stockinger, William Thomas, Patrick Hayes

Department of Agronomy and Horticulture: Faculty Publications

One option to achieving greater resiliency for barley production in the face of climate change is to explore the potential of winter and facultative growth habits: for both types, low temperature tolerance (LTT) and vernalization sensitivity are key traits. Sensitivity to short-day photoperiod is a desirable attribute for facultative types. In order to broaden our understanding of the genetics of these phenotypes, we mapped quantitative trait loci (QTLs) and identified candidate genes using a genome-wide association studies (GWAS) panel composed of 882 barley accessions that was genotyped with the Illumina 9K single-nucleotide polymorphism (SNP) chip. Fifteen loci including 5 known …

Yield And Yield Component Development In Dual-Purpose Barley, A. K. Singh, Pradeep Saxena

IGC Proceedings (1997-2023)

Barley (Hordeum vulgare L.) is a widely adapted small-grain annual cereal and is a key feed and fodder in India (Kharub et al., 2013). Barley can provide nutrition to the animals through its green fodder at vegetative stage and grains after harvest from the regenerated plants. The vegetative portion of the crop is valuable as a source of pasture, cut green forage, and straw. Their relative importance is determined at different ontogenetic stages of plant. An area of barley breeding receiving increasing attention is the development of dual-purpose (green forage and grain) varieties for plains as well as …

Fodder Yield And Quality Of Egyptian Clover (Trifolium Alexandrinum L.), Annual Ryegrass (Lolium Multiflorum Lam.), And Barley (Hordeum Vulgare L.) Monocultures As Affected By Organic And Mineral Fertilization, Heba Sabry Attia Salama

IGC Proceedings (1997-2023)

Egyptian clover (Trifolium alexandrinum L.) is the most important forage legume crop in Egypt. Despite the fact that its yield and protein content are high, it is characterized by low dry matter content especially in the 1st cut, in addition to its limited energy supply, attributed to the low carbohydrate content. Therefore, there is a pressing need to introduce some promising winter annual forage grasses, like barley (Hordeum vulgare L.) and ryegrass (Lolium multiflorum L.), and investigate their performance under the Egyptian agricultural conditions. This would enhance the Egyptian animal production systems by providing a high-quality feed …

Winter Crop Evaluation For Silage And Forage Quality In Korea, J. D. Kim, H. W. Lee, J. K. Lee, J. K. Kim, C. H. Kwon

IGC Proceedings (1997-2023)

Winter crops of rye, barley, oats and Italian ryegrass are used alone or combined as silage crops or green forage in autumn and spring in Korea. The production and utilization of winter crops have been increasing since 2000, because of high yield and double cropping potential in the rice field after harvesting rice. An advantage of these winter crops is that they are produced in the cool season. However, a main problem in making silage with these winter crops is that they are sometimes poor in quality for various reasons.

Therefore we conducted a survey of farms and forage selling …

Flor Revisited (Again): Eqtl And Mutational Analysis Of Nb-Lrr Mediated Immunity To Powdery Mildew In Barley, Roger P. Wise, Priyanka Surana, Gregory S. Fuerst, Ruo Xu, Divya Mistry, Julie A. Dickerson, Dan Nettleton Dr.

Dan Nettleton

Genes encoding early signaling events in pathogen defense often are identified only by their phenotype. Such genes involved in barley-powdery mildew interactions include Mla, specifying race-specific resistance; Rar1 (Required for Mla12-specified resistance1), and Rom1 (Restoration of Mla-specified resistance1). The HSP90-SGT1-RAR1 complex appears to function as chaperone in MLA-specified resistance, however, much remains to be discovered regarding the precise signaling underlying plant immunity. Genetic analyses of fast-neutron mutants derived from CI 16151 (Mla6) uncovered a novel locus, designated Rar3 (Required for Mla6-specified resistance3). Rar3 segregates independent of Mla6 and Rar1, and rar3 mutants are susceptible to Blumeria graminis f. sp. hordei …

Determination Of Optimum Harvest Date For Winter Malting Quality Barley In Northwest Arkansas, Paul Wolf

Crop, Soil and Environmental Sciences Undergraduate Honors Theses

Due to the strict quality requirements, only 10 percent of worldwide barley is used for malting, though malting quality barley comes with a price increase of up to 50 percent or higher. With the craft brewery industry growing in Northwest Arkansas there is a growing demand for locally sourced malt quality barley. However, data is lacking regarding production practices for barley in Arkansas. The optimum harvest date for malting quality barley is at physiological maturity. This is because many of the malting traits (such as germination energy) decline as harvest is delayed, which will make it difficult to meet the …

Salt Stress Induces Non-Cg Methylation In Coding Regions Of Barley Seedlings (Hordeum Vulgare), Moumouni Konate, Michael J. Wilkinson, Benjamin T. Mayne, Stephen M. Pederson, Eileen S. Scott, Bettina Berger, Carlos M. Rodriguez Lopez

Horticulture Faculty Publications

Salinity can negatively impact crop growth and yield. Changes in DNA methylation are known to occur when plants are challenged by stress and have been associated with the regulation of stress-response genes. However, the role of DNA-methylation in moderating gene expression in response to salt stress has been relatively poorly studied among crops such as barley. Here, we assessed the extent of salt-induced alterations of DNA methylation in barley and their putative role in perturbed gene expression. Using Next Generation Sequencing, we screened the leaf and root methylomes of five divergent barley varieties grown under control and three salt concentrations, …

Stored Grain Pack Factor Measurements For Soybeans, Grain Sorghum, Oats, Barley, And Wheat, Rumela Bhadra, Mark E. Casada, Aaron P. Turner, Michael D. Montross, Sidney A. Thompson, Samuel G. Mcneill, Ronaldo G. Maghirang, Josephine M. Boac

Biosystems and Agricultural Engineering Faculty Publications

Grain and oilseed crops stored in bins undergo compaction due to overbearing pressure of the grain inside the structure. Thus, volume measurements of grain in bins need to be combined with the amount of packing (usually called pack factor) in addition to the initial density so that the mass in the structure can be calculated. Multiple pack factor prediction methods are in use in the grain industry, but they have only been validated in the literature and compared with field data for corn and hard red winter wheat. Predictions from WPACKING, the program in ASABE Standard EP413.2, and two standard …

Bulk grain angle of repose (AoR) is a key parameter for inventorying grain, predicting flow characteristics, and designing bins and grain handling systems. The AoR is defined for two cases, piling (dynamic) or emptying (static), and usually varies with grain type. The objective of this study was to measure piling angles of repose for corn, sorghum, barley, soybeans, oats, and hard red winter (HRW) wheat in steel and concrete bins in the United States. Angles were measured in 182 bins and 7 outdoor piles. The piling AoR for corn ranged from 15.7° to 30.2° (median of 20.4° and standard deviation …

Impact Of Pre-Anthesis Water Deficit On Yield And Yield Components In Barley (Hordeum Vulgare L.) Plants Grown Under Controlled Conditions, Zakaria I. Al-Ajlouni, Ayed Al-Abdallat, Abdul Latief A. Al-Ghzawi, Jamal Y. Ayad, Jamal M. Abu Elenein, Nisreen A. Al-Quraan, P. Stephen Baenziger

Department of Agronomy and Horticulture: Faculty Publications

Drought at pre-anthesis stages can influence barley growth and results in yield losses. Therefore, it is important to understand how drought at pre-anthesis can affect different traits associated with yield reduction in barley. The objective of this study was to understand the relevance of the genetic background of major flowering time genes in barley plants subjected to pre-anthesis drought and its impact on yield and yield components. A glasshouse experiment using a Randomized Complete Block Design was conducted to investigate the effect of drought and its timing on yield and yield components on eleven barley genotypes, which were selected to …

Producing Quality Barley For The Malting Industry, Haley H. Oser Dph

Doctor of Plant Health Program: Dissertations and Student Research

The University of Nebraska – Lincoln Doctor of Plant Health program requires each student to fulfill a professional internship over the last summer of the program. For my internship, I worked as a Barley Scientist Intern for MillerCoors and Golden Malting in Golden, Colorado. During this internship I gained a fundamental understanding of malting barley production with a significant emphasis on grain quality. Barley produced for malting must fulfill strict industry quality standards before it is accepted by the head maltsters. These quality standards include: a high germination rate, low moisture content, protein content within an acceptable range and the …
