Utah State University Extension strives to provide research-based information and knowledge to help agricultural producers. Producers often have questions about several aspects of field crop production. This article is not comprehensive of all questions about field crops but represents some of the common questions that USU faculty have received from the public, producers, and crop advisors.

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.

Control Small Weeds In Crops, Department Of Primary Industries And Regional Development, Western Australia

Biosecurity factsheets

In an integrated weed management program, control of weeds should occur in the fallow, pre-sowing, early post-emergent, and in-pasture phases. Weed control can be achieved through killing weeds (particularly seedlings) with cultivation, herbicides, targeted weed control in wide-row cropping, targeted control of small patches of weeds, and biological control tactics.

Factors Affecting Herbicide Performance, Department Of Primary Industries And Regional Development, Western Australia

Biosecurity factsheets

Herbicide performance can vary greatly depending on factors including compatibility of herbicides, water quality, sprayer decontamination, and controlling stressed weeds. This page outlines these issues and demonstrates how to assess herbicide performance to achieve the best from your herbicides.

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.

Leaf Rust And Stripe Rust And Their Management In Wheat, Department Of Primary Industries And Regional Development, Western Australia

Biosecurity factsheets

Leaf rust (Puccinia triticina) and stripe rust (Puccinia striiformis f. sp. tritici) can be a significant threat to wheat crops in Western Australia in some seasons. Learn the symptoms and risk factors.

Managing Crop Weeds, Department Of Primary Industries And Regional Development, Western Australia

Biosecurity factsheets

In-crop weed competition causes losses costing around $1 billion per annum for Western Australia. There are effective strategic and tactical options available to manage weed competition that will increase crop yields and profitability.

Weeds with herbicide resistance are an increasing problem in grain cropping enterprises. Integrated weed management (IWM) is a system for managing weeds over the long term and is particularly useful for managing and minimising herbicide resistance.

Growers are advised to adopt integrated weed management (IWM) to reduce the damage caused by herbicide-resistant weeds.

Herbicide resistant weed populations are found throughout all cropping areas of Western Australia. The …

Editorial: Genetic Validation And Its Role In Crop Improvement, Ahmed Sallam, Ahmad M. Alqudah, P. Stephen Baenziger, Awais Rasheed

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 …

Economic Contribution Of Agriculture And Food To Arkansas’ Gross Domestic Product 1997-2021, Leah English, Jennie Popp

Research Reports and Research Bulletins

Agricultural production, processing, and retail industries are major contributors to Arkansas’ GDP. Agriculture contributes to the state economy through direct agricultural production, value-added processing, and agricultural retail activities. The Agriculture and Food Sector, which is comprised of agricultural production, processing, and retail industries, promotes economic strength through various interactions with other industries. The use of non-agricultural goods and services as inputs into the agricultural sector promotes diversified growth in Arkansas’ economy and thus plays a vital role in maintaining economic stability throughout the state. This report 1) compares the relative size of the Agriculture and Food Sector in Arkansas with …

Metformin Uptake And Translocation In Chickpeas: Determination Using Liquid Chromatography−Mass Spectrometry, Brett Nespor, Anastasia Andrianova, Sean Pollack, Creighton Pfau, Muhammad Arifuzzaman, Nazrul Islam, Alena Kubatova, Khwaja Hossain

Chemistry Faculty Publications

Multiple chronic conditions (MCCs) such as diabetes, hypertension, heart disease, arthritis, asthma, and common respiratory problems are prevalent in over one-fourth of Americans, and separate drugs are prescribed to manage each of the diseases. The nutritive crop seeds loaded with multiple drugs could be a cheap and sustainable alternative to drugs produced by pharmaceutical companies. Our long-term goal is to produce chickpea seeds containing comparable dosages of multiple drugs regularly prescribed for managing MCC. In this work, we conducted experiments to understand the uptake and translocation of metformin into the tissues of chickpea to demonstrate the applicability of LC–HR-ToF-MS in …

The Impact Of Genetic Changes During Crop Domestication, Petr Smýkal, Matthew N. Nelson, Jens D. Berger, Eric J.B. Von Wettberg

College of Agriculture and Life Sciences Faculty Publications

Humans have domesticated hundreds of plant and animal species as sources of food, fiber, forage, and tools over the past 12,000 years, with manifold effects on both human society and the genetic structure of the domesticated species. The outcomes of crop domestication were shaped by selection driven by human preferences, cultivation practices, and agricultural environments, as well as other population genetic processes flowing from the ensuing reduction in effective population size. It is obvious that any selection imposes a reduction of diversity, favoring preferred genotypes, such as nonshattering seeds or increased palatability. Furthermore, agricultural practices greatly reduced effective population sizes …

Genetically Engineered Crops: Emerging Opportunities, Paul C. Vincelli

Agriculture and Natural Resources Publications

Biotechnology is “any technological application that uses biological systems, living organisms, or derivatives thereof, to make or modify products or processes for specific use.” This definition encompasses many, many applications, including traditional ones such as fermentation of alcoholic beverages.

In certain biotech crops, their genetic material (DNA) has been purposefully manipulated in the laboratory. These genetically engineered crops are often called “GMOs,” an acronym for “genetically modified organisms.” These GMOs are the focus of this publication.

Agricultural Lime Recommendations Based On Lime Quality [2016], Edwin L. Ritchey, Lloyd W. Murdock, David C. Ditsch, Joshua M. Mcgrath, Frank J. Sikora

Agriculture and Natural Resources Publications

Soil acidity is one of the most important soil factors affecting crop growth and ultimately, yield and profitability. It is determined by measuring the soil pH, which is a measure of the amount of hydrogen ions in the soil solution. As soil acidity increases, the soil pH decreases. Soils tend to be naturally acidic in areas where rainfall is sufficient to cause substantial leaching of basic ions (such as calcium and magnesium), which are replaced by hydrogen ions. Most soils in Kentucky are naturally acidic because of our abundant rainfall. Nitrogen fertilization can also contribute to soil acidity as the …
