Salt stress influences maize growth and development. To decode the genetic basis and hub genes controlling salt tolerance is a meaningful exploration for cultivating salt-tolerant maize varieties. Herein, we used an association panel consisting of 305 lines to identify the genetic loci responsible for Na+- and K+-related traits in maize seedlings. Under the salt stress, seven significant single nucleotide polymorphisms were identified using a genome-wide association study, and 120 genes were obtained by scanning the linkage disequilibrium regions of these loci. According to the transcriptome data of the above 120 genes under salinity treatment, we conducted a weighted gene ...

Phenotypic Plasticity Of Diverse Sorghum Varieties In Response To Nitrogen Deficit Stress, Mackenzie Zwiener 2021 University of Nebraska-Lincoln

Phenotypic Plasticity Of Diverse Sorghum Varieties In Response To Nitrogen Deficit Stress, Mackenzie Zwiener

Theses, Dissertations, and Student Research in Agronomy and Horticulture

The movement of nutrients from old vegetative tissue to young leaves and reproductive organs is known as senescence. Senescence can be influenced by the environment of a plant, such as, drought, heat, and nutrient stress. These environmental stressors can also influence canopy architecture. Crop canopy consists of several traits including: leaf number, angle, length and width. Past research in crops like maize and rice have shown significant influences of more erect leaves, including, the ability for increased planting density, which optimizes light interception and increases yield. In a field trial of a sorghum association panel including 345 different sorghum varieties ...


Essays On Agricultural Technology, Resource Allocation And The Value Of Information, Pedro Queiroz 2021 University of Nebraska-Lincoln

Essays On Agricultural Technology, Resource Allocation And The Value Of Information, Pedro Queiroz

Dissertations and Theses in Agricultural Economics

This dissertation studied the adoption of agricultural technologies and the value of information for the allocation of resources in agriculture. Chapter 1 studied traditional (e.g., land and labor) and commercial (e.g., machinery and fertilizers) inputs in South American agriculture. Acemoglu’s directed technical change was used to estimate the process of induced innovation using deforestation as source of exogenous variation for the agricultural land supply. The results indicated that larger availability of land in intensive deforestation countries caused more land-complementary inputs (machinery) to be used relative to labor-complementary inputs (fertilizers). Technical change was biased towards land. Chapter 2 ...


Changes In Whole Blood Parameters In Beef Heifers May Contribute To Delayed Pubertal Attainment, Jessica A. Keane 2021 University of Nebraska-Lincoln

Changes In Whole Blood Parameters In Beef Heifers May Contribute To Delayed Pubertal Attainment, Jessica A. Keane

Theses and Dissertations in Animal Science

Pubertal development in beef heifers is a transient period that has many contributing factors. Previously in our lab, progesterone (P4) concentrations collected from heifers at weaning (Oct) to breeding (May) were used to identify four distinct pubertal groups: Typical, Early, Start-Stop, and Non-Cycling. There is limited research on heifers and the impacts of whole blood cell populations, particularly WBCs, during pubertal development; however, girls with differing puberty onset displayed altered concentrations of hematocrit, white blood cells (WBC), and hemoglobin concentrations. Thus, our hypothesis was that heifer pubertal groups with delayed or precocious puberty may have increased white blood cells or ...

Key Factors Involved In Reduction Of Damage To Sunflower By The European Sunflower Moth In China Through Late Planting, Yunxia Cheng, Thomas W. Sappington, Lizhi Luo, Chenguang Liu, Yongjun Wang, Shuangping Liu, Zongze Zhang, Lijun Wang, Xingfu Jiang

Entomology Publications

The European sunflower moth, Homoesoma nebulellum (Denis et Schiffermüller), emerged as a major new pest in Bayannur, China, in 2006. Insecticidal control with a single application is problematic because timing is critical, and multiple applications increase production and environmental costs. Management of H. nebulellum by planting date adjustment can be effective, but the optimal time window for late planting is unknown. Natural levels of H. nebulellum infestation were compared among sunflowers planted on five dates from April 25 to June 5 in two years, and the relationship between timing of adult abundance and flowering assessed. Delaying planting of sunflower from ...


High Mortality Rates For Bean Leaf Beetle In Northern Iowa, Ashley Dean, Erin W. Hodgson 2021 Iowa State University

High Mortality Rates For Bean Leaf Beetle In Northern Iowa, Ashley Dean, Erin W. Hodgson

Integrated Crop Management News

Bean leaf beetle adults (Photo 1) are susceptible to cold weather and most will die when air temperatures fall below 14°F (-10°C). However, they have adapted to winter by protecting themselves from harsh temperatures under plant debris and loose soil. Each spring, adult beetles emerge from their overwintering habitat and migrate to available hosts, such as alfalfa, tick trefoil, and various clovers. As the season progresses, bean leaf beetles move to preferred hosts, like soybean. While initial adult activity can begin before soybean emergence, peak abundance often coincides with early-vegetative soybean.

Termination Timing Of Cereal Rye Cover Crop For Improved Weed Control In Soybean, Prashant Jha 2021 Iowa State University

Termination Timing Of Cereal Rye Cover Crop For Improved Weed Control In Soybean, Prashant Jha

Integrated Crop Management News

Current cooler weather conditions are posing challenges for growers with a cereal rye cover crop to get it terminated. However, for growers planning to plant soybeans into the rye cover crop, there may be a perk to letting the rye cover crop accumulate more biomass. That perk being the cover crop biomass can help with weed suppression. The ability of cereal rye to suppress weeds is directly related to the biomass accumulation at the time of termination.


The Importance Of Goats In The World, Mahendra Lohani, Dilip Bhandari 2021 Heifer International, Little Rock, AR

The Importance Of Goats In The World, Mahendra Lohani, Dilip Bhandari

Professional Agricultural Workers Journal

It is a challenge to transform the mindset of subsistence farmers to consider goats as a productive asset. Goat health, breeding, housing and nutrition are the main challenges in a smallholder production system. The development of the goat market sector is informal and underdeveloped. As a result, goats have not been identified as a significant contributor to the national gross domestic product. Many development organizations consider goats a preferred livestock commodity for poverty alleviation. Therefore, it is desirable to have a systematic approach to optimize goat production for smallholders. A smallholder goat value chain works well with a focus on ...

To Terminate Or Not To Terminate?, Robert G. Hartzler 2021 Iowa State University

To Terminate Or Not To Terminate?, Robert G. Hartzler

Integrated Crop Management News

Current cool temperatures increase the risk of failures in terminating cover crops. While cereal rye continues to grow during these conditions, activity of herbicides is reduced. Translocation of glyphosate to growing points is reduced under cool temperatures, slowing activity and increasing the potential for control failures. It is generally recommended to avoid applications when nighttime temperatures fall below 40 F, and we prefer temperatures at application to be at least in the mid-50s with clear skies. Based on current forecasts, herbicide applications to terminate in many areas of the state should be delayed until more favorable conditions exist.


The Influence Of Adjuvants On Physical Properties, Droplet-Size, And Efficacy Of Glufosinate And Dicamba Plus Glyphosate Solutions, Estefania Gomiero Polli 2021 University of Nebraska-Lincoln

The Influence Of Adjuvants On Physical Properties, Droplet-Size, And Efficacy Of Glufosinate And Dicamba Plus Glyphosate Solutions, Estefania Gomiero Polli

Theses, Dissertations, and Student Research in Agronomy and Horticulture

Adjuvants are used in agriculture to improve herbicide activity or application performance. The addition of adjuvants to herbicide solution can enhance its penetration, wettability, and evaporation rates by altering density, viscosity, contact angle between the droplet and plant surface, and droplet surface tension. Furthermore, those alterations in the physical properties of the herbicide solution can result in changes in the droplet-size distribution that directly impact herbicide efficacy. The adoption of glufosinate-based herbicide programs has increased with the widespread occurrence of glyphosate-resistance (GR) weeds in recent years. Also, tank mixture of dicamba and glyphosate has been largely adopted for broad-spectrum weed ...


Utah Livestock Producer Preferred Drought Management Strategies, Kynda R. Curtis, Tatiana Drugova, Ruby Ward 2021 Utah State University

Utah Livestock Producer Preferred Drought Management Strategies, Kynda R. Curtis, Tatiana Drugova, Ruby Ward

All Current Publications

This fact sheet, the second in a series of three, examines livestock producer preferred drought management strategies and how producer preferences change depending on drought severity and expected grazing efficiency. Severe drought in livestock production leads to decreases in feed availability, range or hay quality, and overall lower quality beef (Holupchinski et al., n.d.). Hence, drought increases production costs and producer dependence on imported feed. Thus, extended drought poses a threat to agricultural productivity and the economies of rural and tribal areas in Utah.
