Hay – Essentials For Growing A Successful Crop, Department Of Primary Industries And Regional Development, Western Australia
Grains and other field crops factsheets
Export hay fits into most of the accepted cropping rotations and helps reduce weed seed banks, overcome herbicide resistance, provides a break from traditional chemical regimes and good paddock preparation for the subsequent crop, and is an alternative profitable crop.
Talk to your local hay exporter about their requirements for hay produced for export before sowing oats for export hay. Hay exporters have different requirements, which will affect how you manage your crop.

Loose Smut Of Barley And Its Management, Department Of Primary Industries And Regional Development, Western Australia
Loose Smut Of Barley And Its Management, Department Of Primary Industries And Regional Development, Western Australia
Biosecurity factsheets
The fungal disease loose smut of barley parasitises the host plant and produces masses of soot-like spores that infect the seed head, reducing the yield and quality of harvested grain.
Smut diseases are host specific, meaning that smut of one cereal crop will not infect others (for example, loose smut of barley does not infect wheat or oats).
In many cases grain receival points have low or zero tolerance of smut contaminated grain.

Fungal Plant Pathogens Affecting Crops In The Lower Rio Grande Valley, Isabel Martinez
Theses and Dissertations
The Lower Rio Grande Valley (LRGV) located in South Texas has a subtropical and humid environment which is conducive for plant disease. In Chapter 1, Southern blight caused by Athelia rolfsii was collected from Edinburg, Texas in tomato and bean crops. The present study focused on assessing the role of temperature on growth and sclerotia production. We found that there is an optimal growing temperature for both hyphal growth and sclerotia production. In Chapter 2, red rot fungal disease was collected from sugarcane in Texas. Morphology, pathogenicity, effects of temperature, and biocontrol agents were assessed. Isolate morphology closely resembled Fusarium …

Department of Agronomy and Horticulture: Faculty Publications
Gene discovery for economically important traits has remained a challenging Frontier in crop genomics and breeding. The recent advances in DNA sequencing technologies and genetic analysis approaches paved the way for discovering many genes and hotspot genomic regions controlling target traits. The detection of novel genomic regions or candidate genes is very useful for plant breeders and geneticists to improve crops, dissect the genetics of complex traits, and understand the biological mechanisms of genes underpinning traits of interest. Quantitative trait loci (QTL) mapping and genome-wide association studies (GWAS) dominated recent crop gene discovery research. These studies are becoming routine activities …

Plant Diseases Impacting Oaten Hay Production In Australia - A Review, Kylie Chambers, Geoff J. Thomas
Plant Diseases Impacting Oaten Hay Production In Australia - A Review, Kylie Chambers, Geoff J. Thomas
Bulletins 4000 -
In Australia, there are a range of fungal, bacterial and viral pathogens that infect oats, impacting on yield and quality of grain and hay crops. The overall impact of these diseases on oaten hay production is not well researched or understood, especially compared to that of other cereal crops. Export hay is evaluated on physical qualities such as stem thickness and greenness and nutritional qualities including water-soluble carbohydrates, neutral detergent fibre, acid detergent fibre and dry matter digestibility. The colour/ greenness of oaten hay can be reduced by disease lesions, chlorosis and saphrophytic fungi growing on dead tissue all of …

Legumes Of Forage Value: Their Diversity And Priority For Collection In India, E. Roshini Nayar, Anjula Panndey, K. Pradheep, Rita Gupta
IGC Proceedings (1993-2023)
Indian subcontinent is a megacentre of agro-diversity. Legumes have a special place with several native crops and economically important species occurring along forest margins and openings, pastures, grasslands and grazing lands. Several are dual-purpose species for food and feed. However, herbage legumes though major components of grasslands and with a major role in their quality and improvement lack persistence as compared to grasses and their collection, maintenance and conservation assumes importance in the wake of change and loss of habitats of native species and introduction of new germplasm with forage potential. Establishing the correct identity of species is therefore a …

Agricultural and Environmental Sciences Faculty Research
Nitrogen (N) fertilization affects bioenergy crop growth and productivity and consequently carbon (C) and N contents in soil, it however remains unclear whether N fertilization and crop type individually or interactively influence soil organic carbon (SOC) and total N (TN). In a three-year long fertilization experiment in switchgrass (SG: Panicum virgatum L.) and gamagrass (GG: Tripsacum dactyloides L.) croplands in Middle Tennessee USA, soil samples (0–15cm) were collected in plots with no N input (NN), low N input (LN: 84 kg N ha-1 yr-1 in urea) and high N input (HN: 168 kg N ha-1 yr-1 in urea). Besides SOC …

John E. Sawyer
Originally used to prevent scale in boilers, carpramid or thermal polyaspartate (copoly[(3-carboxypropionamide)( 2-carboxylmethyl) acetamide)] was brought to agriculture under the trade names AmiSorb and Magnet. It claimed to increase nutrient uptake through artificially increasing the volume of soil occupied by roots through increased root branching and root hair development. Under controlled hydroponic or greenhouse conditions, the use of carpramid increased nutrient uptake, some yield determining factors such as wheat tillering and in some cases, crop yield. Extensive field testing from 1996 to 1998 under various nutrient regimes, placements, forms, and timings resulted in very inconsistent performance. Averaged across all experiments …

Dynamic Patterns Of Expression For Genes Regulating Cytokinin Metabolism And Signaling During Rice Inflorescence Development, Maria V. Yamburenko, Joseph J. Kieber, G. Eric Schaller
Dartmouth Scholarship
Inflorescence development in cereals, including such important crops as rice, maize, and wheat, directly affects grain number and size and is a key determinant of yield. Cytokinin regulates meristem size and activity and, as a result, has profound effects on inflorescence development and architecture. To clarify the role of cytokinin action in inflorescence development, we used the NanoString nCounter system to analyze gene expression in the early stages of rice panicle development, focusing on 67 genes involved in cytokinin biosynthesis, degradation, and signaling. Results point toward key members of these gene families involved in panicle development and indicate that the …
Seed Biology And Yield Of Grain Crops, Dennis B. Egli
Seed Biology And Yield Of Grain Crops, Dennis B. Egli
Plant and Soil Sciences Faculty Book Gallery
Description from CABI (Centre for Agriculture and Biosciences International):
This new edition of an established title examines the determination of grain crop yield from a unique perspective, by concentrating on the influence of the seed itself. As the food supply for an expanding world population is based on grain crops harvested for their seeds, understanding the process of seed growth and its regulation is crucial to our efforts to increase production and meet the needs of that population. Yield of grain crops is determined by their assimilatory processes such as photosynthesis and the biosynthetic processes in the seed, which are …
Measuring Soil Electrical Conductivity To Delineate Zones Of Variability In Production Fields, Gretchen Sassenrath, S. Kulesza
Measuring Soil Electrical Conductivity To Delineate Zones Of Variability In Production Fields, Gretchen Sassenrath, S. Kulesza
Kansas Agricultural Experiment Station Research Reports
Production fields in southeast Kansas are highly variable. Differences in elevation and changes in soil texture contribute to unevenness in plant-available moisture and nutrients, resulting in significant inconsistencies in crop production and yield within a field. These variabilities complicate management and impact the return on investments from different areas of the field. Identification of the regions of variability is possible through several methods, including visual inspection, remote imagery, and yield maps. An additional method of assessing soil variability is by measuring the electrical conductivity of the soil. Measuring apparent electrical conductivity gives a map of the spatial distribution of soil …
