Forage Productivity Evaluation And Geographic Information Systems In Temperate Semi-Arid Agro-Ecosystem, H Salinas, R Ramirez, J Zegbe, G Medina, R A. Martinez

IGC Proceedings (1997-2023)

700,000 ha of the temperate semi-arid area of Zacatecas state are grown with rainfed crops. Low productivity is obtained from these crops: 350 kg/ha of beans grain and 500 kg/ha of corn grain. This state is characterized by a wide range of topographic and climatic values. A need for alternative crops led to establishment of a trial to evaluate rainfed forages, and to know in what range these could be located. Geographic information systems were used to find out the potential area of the species. Results indicated that sorghum presented a higher yield (5822 kgDM/ha) than sorghum x sudan (5460), …

Small Grains In Cropping Systems To The Brazilian Southern Regions, R S. Fontanelo, L De J.A Del Duca, R S. Fontaneli

IGC Proceedings (1997-2023)

Winter cereals genotypes (oats, wheat, rye, barley, and triticale) were evaluated for forage and grain yield at the experimental area of the Wheat National Research Center (EMBRAPA/CNPT) and Agronomy College of the Universidade de Passo Fundo (UPF/FA), in Passo Fundo, RS state, southern Brazil, during the years 1992-94. Three cutting frequencies were applied: no cutting, one and two cuttings. A completely random block design with split-plots and three replicates was used. The crops were established under conventional tillage. The fertilization was 200- 300 kg/ha 5-25-25 , plus 22.5-30.0 kg/ha of N (urea) during tiller period (before 45 days after planting …

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 …

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 …

Field-Observed Angles Of Repose For Stored Grain In The United States, Rumela Bhadra, Mark E. Casada, Sidney A. Thompson, Josephine M. Boac, Ronaldo G. Maghirang, Michael D. Montross, Aaron P. Turner, Samuel G. Mcneill

Biosystems and Agricultural Engineering Faculty Publications

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 …

Barsoy-A New Winter Barley, V. C. Finkner, S. H. Phillips

Agronomy Notes

The early maturity of Barsoy winter barley will fill a gap in the maturity dates of the barley varieties presently recommended. Double cropping of small grain and wheat has grown to the extent that 30,000 to 40,000 acres in Kentucky grow two crops each year. This practice will continue to develop and become more important on grain farms. The early maturity characteristic of Barsoy will allow an earlier planting of soybeans than will other barley varieties.

Barley - Oat Varieties, 1963, S. H. Phillips

Agronomy Notes

Selection of barley and oat varieties is important to growers of these small grains. Tests are conducted across Kentucky by the University of Kentucky Agronomy Department to determine yield, winter hardiness, disease resistance, standability, and other characteristics important to efficient production. Planting dates are more important for these two crops than for wheat and rye because of winter freeze damage. The best planting dates for barley and oats run from September 1 to September 20. Later plantings are made in Kentucky but are subject to more damage from cold weather. Increased planting rates in barley tend to improve yield in …
