Agricultural Production From The High Plains Aquifer Is Worth Over $3 Billion Per Year, Richard K. Perrin, Lilyan E. Fulginiti, Federico Garcia

Cornhusker Economics

Recent research (Garcia, Fulginiti and Perrin, 2018) has shown the that the extra agricultural production from irrigation across the High Plains Aquifer (HPA) was worth about $3.5 billion in 2007, $2 billion of which was produced in Nebraska. The aquifer water is valuable!

Assessing Water Policy Implications Of The Changing Agriculture In New Mexico, Trevor A. Birt

Shared Knowledge Conference

Agriculture is the dominant water sector in New Mexico, responsible for more than 80% of water withdrawals in 2015 (USGS 2018). Water policy needs to be extremely adaptive and informed to meet the needs of not only farmers, but cities, industry and riparian uses. Since 1840, the U.S. Department of Agriculture (USDA) has conducted census surveys assessing all levels of agriculture. These data are physically published at the county, state, and national level on a 5-year cycle, detailing various material counts such as acreage, yields, and water usage, as well as socioeconomic estimates of farm costs, revenues, and hired workers. …

The Economics Of The Capitalization Rate For Farmland, Jeff Stokes, Jim Jansen

Cornhusker Economics

There are three approaches that real estate appraisers use to value real property, namely, the market or sales comparison approach, the income approach, and the cost approach. The sales comparison approach is the primary way that residential real estate is appraised with the cost approach thrown in for good measure. For income producing properties, which includes commercial real estate as well as farm real estate, all three approaches are frequently used. When there are minimal improvements on farmland, the sales comparison and income approaches often provide competing estimates of value that must be reconciled so that an appraiser can render …

Wild Bees Of Grand Staircase-Escalante National Monument: Richness, Abundance, And Spatio-Temporal Beta-Diversity, Olivia Messinger Carril, Terry Griswold, James Haefner, Joseph S. Wilson

All PIRU Publications

Interest in bees has grown dramatically in recent years in light of several studies that have reported widespread declines in bees and other pollinators. Investigating declines in wild bees can be difficult, however, due to the lack of faunal surveys that provide baseline data of bee richness and diversity. Protected lands such as national monuments and national parks can provide unique opportunities to learn about and monitor bee populations dynamics in a natural setting because the opportunity for large-scale changes to the landscape are reduced compared to unprotected lands. Here we report on a 4-year study of bees in Grand …

South American Leaf-Cutter Bees (Genus Megachile) Of The Subgenera Rhyssomegachile And Zonomegachile, With Two New Subgenera (Hymenoptera: Megachilidae), Víctor H. González, Terry Griswold, Michael S. Engel

All PIRU Publications

Leaf-cutter bees (genus Megachile Latreille) are among the most common and diverse group of bees. However, the identity and taxonomic placement of many species are problematic and species identification is often difficult. Some species are known only from a single specimen or from one of the sexes, and identification keys are not available for many groups. We address these taxonomic issues for the subgenera Rhyssomegachile Mitchell and Zonomegachile Mitchell, two poorly known South American lineages of leaf-cutter bees. We provide comparative diagnoses, redescriptions, illustrated identification keys, new geographical records, and designate needed neotypes for Megachile cara Mitchell, M. gigas Schrottky, …

Hydrological Hazard Assessment For Irrigated Agriculture In The Irwin Focus Area, Russell J. Speed, Adele L. Killen

Resource management technical reports

The Midlands groundwater and land assessment project aimed to identify 2000–3000 hectare precincts suitable to develop intensive irrigated horticulture. The primary focus area was at Irwin, where the Department of Water and Environmental Regulation investigated groundwater resources and the Department of Primary Industries and Regional Development undertook a multi-faceted site assessment. This report describes the hydrological hazards assessment for the Irwin focus area.

The Irwin focus area is located on fertile loam and clay flats associated with the Irwin River. In the east, it encompasses the Irwin River valley floor and the western boundary loops to the south of the …

Biosecurity Council Of Western Australia Annual Report 2017/2018, Biosecurity Council Of Western Australia

Biosecurity published reports

There were two key areas in which the Council focused during the year:

• environmental biosecurity; and
• the attributes required by a biosecurity ‘combat’ agency to effectively sustain a biosecurity response.

In addition, planning began for two new areas of advice to Government – biosecurity research and development; and border biosecurity.

Developing constructive advice to Government requires a comprehensive understanding of the needs and challenges of industry, Government and the community. It also requires an understanding of how changes to the biosecurity system might impact these groups and affect the State’s biosecurity status. During 2017/18 the Council continued to monitor biosecurity …

Shay Gap Soil Survey: Investigating The Suitability Of Soils And Landforms For Irrigated Agriculture In The Western West Canning Basin, Paul Galloway, Dennis Van Gool, Justin Laycock, Karen Holmes, David Rowe

Resource management technical reports

This report describes the soil and land resources of the Shay Gap study area (SA), which is south of Wallal Downs Station, in unallocated Crown land in the Shire of East Pilbara. It assesses the study area’s capability for three types of irrigated agriculture and examines land resources to ensure any future irrigation developments are sustainable and do not degrade the environment.

The Shay Gap SA lies within the West Canning Basin, an area of about 3500 square kilometres at the western margin of the onshore Canning Basin. The West Canning Basin has a substantial groundwater resource that provides fresh …

Growth And Development Of Lettuce (Lactuca Sativa L.) In A Hydroponic System With Different Lighting Sources, Ghada Mohammed Ali Hamuda

Aridland Agriculture Theses

The goal of this study was to investigate the influences of different light systems, on growth parameters (fresh and dry weight, height and width, number of leaves and leaf area) and accumulation of chlorophylls and carotenoids of the lettuce. The marketable sensory characteristics (shape, and color) of fresh plants were also evaluated.

(Lactuca sativa crispa. “Lollo bionda”) lettuce were cultured in three levels of vertical hydroponically for 45 days under different light sources of natural light in the upper level, 60% shade light in the middle level and red (R), green (G) blue (B), provided by light-emitting diodes …

Investigation Of Alternative Hosts And Agronomic Factors Affecting Xanthomonas Vasicola Pv. Vasculorum, Causal Agent Of Bacterial Leaf Streak Of Corn, Terra Marie Hartman

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Xanthomonas vasicola pv. vasculorum, causal agent of bacterial leaf streak of corn, was first reported in the U.S. in 2016 on Nebraska corn leaf samples. Prior to this report, the pathogen had only been reported on corn in South Africa. After the Nebraska report, the pathogen was reported on corn in Argentina, Brazil, and several U.S. states. This pathogen has an extensive host range, which includes sugarcane (Saccharum officinarum), grain sorghum (Sorghum bicolor), palm species (Dictyosperma album, Roystonea regia, and Areca catechu) and broom bamboo (Thysanolaena maxima). Plants commonly found in …

Identification Of Genes/Genomic Regions Controlling Resistance To Biotic And Abiotic Stresses In Synthetic Hexaploid Wheat, Madhav Bhatta

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Synthetic hexaploid wheat (SHW; 2n=6x=42, AABBDD, Triticum aestivumL.) is produced from an interspecific cross between durum wheat (2n=4x=28, AABB, T. turgidumL.) and goat grass (2n=2x=14, DD, AegilopstauschiiCoss.). It is reported to have a considerable amount of genetic diversity and is a potential source of novel alleles controlling abiotic and biotic stresses resistance and improving wheat quality. Therefore, the first study was to understand the genetic diversity and population structure of SHWs and compare the genetic diversity of SHWs with elite bread wheat (BW) cultivars. The result of this study identified a wide range of genetic diversity within …

Modeling Effects Of Ecological Factors On Evolution Of Polygenic Pesticide Resistance, C. V. Haridas, Brigitte Tenhumberg

School of Biological Sciences: Faculty Publications

Widespread use of pesticides has resulted in the evolution of resistance in many insect pests worldwide, limiting their use in pest control. Effective pest and resistance management practices require understanding of the genetics of resistance and the life history of the pest. Most models for pesticide resistance assume that resistance is monogenic, conferred by a single gene. However, resistance could evolve as a polygenic quantitative trait resulting from the action of several genes, especially when pesticide dose is low. Further, fitness of the pest could be density dependent and might depend upon abiotic factors such as temperature. It is not …

Identification And Characterisation Of Novel Phages Of Pectobacterium And Erwinia, Colin Buttimer

PhDs

Losses in crop yields due to disease need to be reduced to meet increasing global food demands associated with growth in the human population. There is a well-recognised need to develop new environmentally-friendly control strategies to combat bacterial crop diseases. There are several crop diseases for which no effective bactericidal agents are currently available, such as potato blackleg and soft rot disease caused by Pectobacterium atrosepticum and other members of soft rot Enterobacteriaceae (Czajkowski et al., 2011). Furthermore, current control measures involving the use of traditional chemicals or antibiotics are losing their efficacy due to the natural development of bacterial …

Initiative 427: Nebraska Medicaid Expansion, J. David Aiken

Cornhusker Economics

This article summarizes information regarding Initiative 427–the Medicaid expansion question on the November 6, 2018 ballot. It reprints the actual ballot language and the Nebraska Secretary of State’s summary of arguments for and against Initiative 427.

Background. Originally Medicaid covered the elderly, the disabled, children in low-income families, and low-income pregnant women. In 2010 Medicaid coverage was expanded by Congress to include the working poor. In 2012 the U.S. Supreme Court ruled that the provision of the Affordable Care Act (ACA) requiring states to expand Medicaid was unconstitutional. This made it a state option whether or not to expand Medicaid. …

Interactions Observed With Clomazone Plus Pendimethalin When Mixed With Postemergence Rice Herbicides, Matthew Osterholt

LSU Master's Theses

A study was conducted at the Louisiana State University Agricultural Center’s H. Rouse Caffey Rice Research Station (RRS) in 2017 and 2018 to evaluate whether the pre-packaged mixture of clomazone plus pendimethalin should be applied delayed preemergence (DPRE) or postemergence (POST) within a herbicide residual overlay with saflufenacil, clomazone, or quinclorac. POST applications also included penoxsulam or halosulfuron in combination with the second residual application. No differences were observed with barnyardgrass control at 14 DAT across all treatments with 92 to 98% control. At 42 DAT, barnyardgrass treated with either clomazone plus pendimethalin applied at either timingin combination with either …
