Pesticide Analysis In Vegetables Using Quechers Extraction And Colorimetric Detection, D. S. G. Neufeld, N. Åkerson, D. Barahona

Virginia Journal of Science

A novel combination of extraction and detection methods is demonstrated for pesticide residue analysis in vegetable samples. Acetylcholinesterase (AChE) inhibition was used as a simple colorimetric test for organophosphates/carbamates (OP/C), and was tested with extracts from the widely-used QuEChERS extraction method. In the absence of pesticide, diluted (50% with water) acetonitrile did not inhibit enzyme activity, demonstrating the compatibility of this extraction solvent with the AChE inhibition test. QuEChERS extraction of chlorpyrifos-spiked tomato, spinach and lettuce samples indicated a high sensitivity to OP/C, with AChE inhibition occurring in the ppb range. The applicability of this method combination was tested by …

An Ipm Scouting Guide For Common Problems Of Legume Vegetables In Kentucky, Nicole Ward Gauthier, Ricardo Bessin, Shubin Saha, Shawn Wright, Cheryl A. Kaiser

Agriculture and Natural Resources Publications

Long before the term “sustainable” became a household word, farmers were implementing sustainable practices in the form of Integrated Pest Management (IPM) strategies. IPM uses a combination of biological, cultural, physical, and chemical methods to reduce and/or manage pest populations. These strategies are used to minimize environmental risks, economic costs, and health hazards. Pests are “managed” (but rarely eliminated entirely) to reduce their negative impact on the crop.

Scouting and monitoring diseases, insects, weeds, and abiotic disorders in order to identify potential problems before they result in serious losses is essential to the IPM approach. Proper identification is essential to …

Organic Corn Production In Kentucky, Michael Bomford, Lee Meyer, Thomas Sikora, William Martin, Sam Mcneill, Michael D. Montross, Edwin L. Ritchey, Chad Lee

Agriculture and Natural Resources Publications

The number of organic dairy cows in Kentucky has been steadily increasing for years, yet there’s not enough organic corn produced in the state to feed the growing herds. In fact, most of the organic corn consumed in Kentucky is produced outside of the state. The growing organic livestock and poultry industries in Kentucky face the same feed constraints. In short, a new market has developed in the state, but few local farmers are taking advantage of it.

Crop Yields: Stripper Header Technology Vs. Conventional Header Technology, Kyle D. Michaelis, M. F. Vigil, W. B. Henry

Undergraduate Research Journal

The purpose of this paper is to compare crop yields on acres where stripper header technology was used to those where conventional header technology was used in a dryland cropping system. The results are based on experimental data collected at the USDA-ARS Central Great Plains Research Station, and include information on Northeastern Colorado wheat, millet, and sorghum yields. This analysis is important to demonstrate the benefits of using stripper header technology in a dryland cropping system. In the next section, the approaches and major findings of the previous literature are reviewed.

U.S. Competition Of Hard Spring Wheat Characteristics, Jacquiline Danso

Electronic Theses and Dissertations

There is a changing landscape in the wheat market from the emergence of foreign ownership of local elevators, increased consolidation in the milling sector, technology advancement, and changes in transportation. The changing landscape of the wheat market has been associated with greater degrees of vertical coordination through integration, strategic alliances, and contractual relationships. Particularly greater vertical integration has occurred between the millers, county elevators, and export and country terminal elevators. The greater integration of the milling sector has raised concerns by the Department of Justice Anti-trust division to the competitiveness of the flour market, and has only conditionally approved recent …

Off The Court, Onto The Farm, Arza E. Hammond

Graduate Student Theses, Dissertations, & Professional Papers

This work contains two separate but connected stories about developing a relationship with something larger than myself. Reaching the end of my basketball career forced me to examine my relationship with the great game of basketball and my role in it. After ending my hoops career, I spent a summer working and living on a small, organic farm. The lessons I learned from the game helped me to develop a meaningful relationship with the farm and to find a reciprocal role with the land I lived and worked on.

Elevated Atmospheric Temperature And Co2 Altered The Growth, Carbon, And Nitrogen Distribution And The Rhizosphere Properties Of Platanus Occidentalis L. Seedlings, Venecio U. Ultra Jr., Sim-Hee Han

Turkish Journal of Agriculture and Forestry

The effects of elevated atmospheric temperature and CO2 on the growth and plant carbon and nitrogen allocation of Platanus occidentalis L. and their influence on rhizosphere and soil microbial properties were evaluated through a rhizobag experiment in an environmentally controlled chamber. Seedlings of P. occidentalis L. were established in the central compartment of a rhizobag filled with forest soil and exposed to four treatment combinations (control (25 °C, 400 μmol mol-1 CO2), T2 (30 °C, 400 μmol mol-1 CO2), T3 (25 °C, 800 μmol mol-1 CO2), and T4 (30 °C, 800 μmol mol-1 CO2)) for 20 weeks. Elevated temperature and …

Evaluation Of Pyrosequencing For Large-Scale Identificationof Plant Species (Grasses As A Model), Nadia Haider

Turkish Journal of Agriculture and Forestry

Grasses (Poaceae) are among the most important and widely cultivated plants. Identification of grass species using morphological characters is a difficult task for nonspecialists, and it is not always an accurate method. DNA-based molecular markers have been widely used as an alternative towards more accurate identification of plant species. The molecular method that can be effective for large-scale identification of grass species, however, must satisfy requirements for specific amplification of DNA and reveal enough variability to distinguish species. The goal of this study was to evaluate the ability of pyrosequencing to detect SNP polymorphisms for an optimal discrimination of grass …

Turkish Journal of Agriculture and Forestry

The goal of the performed experiments was to determine the strength, stiffness, and modulus of the elasticity of dowel, mortise and loose-tenon, and mortise and tenon L-type furniture joints under diagonal tension and compression loads. The specimens were constructed from Turkish beech (Fagus orientalis L.), white oak (Quercus alba), and white walnut (Juglans cinerea L.) and were assembled with a water-resistant PVAC adhesive. According to the obtained results, the highest stiffness/strength values were estimated in mortise and tenon joints constructed of white oak, whereas dowel joints constructed from Turkish beech showed the lowest stiffness/strength and deformability. The elasticity modulus of …

Influences Of Different Iron Levels On Plant Growth And Photosynthesis Of W. Murcott Mandarin Grafted On Two Rootstocks Under High Ph Conditions, Meral İncesu, Turgut Yeşi̇loğlu, Berken Çi̇men, Bi̇lge Yilmaz

Turkish Journal of Agriculture and Forestry

W. Murcott scion, budded onto two rootstocks, was evaluated under high pH conditions supplied with different Fe levels. Plant dry weight, leaf area, iron chlorosis symptom scale, leaf chlorophyll concentration, net photosynthetic rate, and ferric-chelate reductase (FCR) activity variables were investigated under high pH conditions. Control plants (T1) produced the most leaf area, whereas plants grown without Fe (T2) produced the least. Dry weight was highest in 'Volkameriana' T1 (control) plants and lowest in 'Swingle citrumelo' T3 (10 μM Fe and 7.8 pH) and T2 (0 μM Fe and 7.8 pH) treatments. Significant differences in SPAD and iron chlorosis scale …

School Gardens: Cultivating A Child’S Nutritional Habits, Environmental Knowledge, And Sustainability Practices, Jeffrey Meltzer

School gardens have existed since the late nineteenth century and today are becoming increasingly popular in many parts of the world, including where I studied in Maine and Australia (AUS). Multiple organizations support school gardens in Maine, including the Maine School Garden Network, which has over 125 registered school gardens. In AUS, the Stephanie Alexander Kitchen Garden Foundation primarily supports the school garden movement and has over 800 registered school gardens. While many researchers have studied school gardens, few have compared two countries, focused on environmental sustainability, or investigated Maine in particular. This thesis combines information from literature reviews, and …

N-Acetylcysteine Increased Rice Yield, Mohd Nozulaidi, Md Sarwar Jahan, Mohd Khairi, Mohammad Moneruzzaman Khandaker, Mat Nashriyah, Yusop Mohd Khanif

Turkish Journal of Agriculture and Forestry

N-acetylcysteine (NAC) biosynthesized reduced glutathione (GSH), which maintains redox homeostasis in plants under normal and stressful conditions. To justify the effects of NAC on rice production, we measured yield parameters, chlorophyll (Chl) content, minimum Chl fluorescence (Fo), maximum Chl fluorescence (Fm), quantum yield (Fv/Fm), net photosynthesis rate (Pn), photosynthetically active radiation (PAR), and relative water content (RWC). Four treatments, N1G0 (nitrogen (N) with no NAC), N1G1 (N with NAC), N0G0 (no N and no NAC), and N0G1 (no N but with NAC), were arranged in a completely randomized design with five replications. Nitrogen significantly increased yield and yield parameters of …

Auxin-Mediated Growth Of Rice In Cadmium-Contaminated Soil, Hussna Farooq, Hafiz Naeem Asghar, Muhammad Yahya Khan, Muhammad Saleem, Zahir Ahmad Zahir

Turkish Journal of Agriculture and Forestry

Pollution from heavy metals is a global problem that is very dangerous to the environment. Among the heavy metals, cadmium is receiving more and more attention because it is one of the most ecotoxic, making it very harmful for biological activity in soil, biodiversity, plant metabolism, and human and animal health. Phytohormones, produced by plants, control or regulate germination, growth, metabolism, or other physiological activities, and they can alleviate the toxic effects of heavy metals on plant growth. Auxin is the most abundant natural growth hormone, controlling apical dominance, tropism, elongation of shoots, and initiation of roots in plants. However, …
