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 …

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 …

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, …

Turkish Journal of Agriculture and Forestry

Climatic conditions of environmental zone Nemoral 2 of Europe are favorable for agricultural development. However, more frequent events of hot air-waves and prolonged droughts occurring as a consequence of climate change lead to soil moisture content reduction down to the plant wilting point. Dry soil conditions may have negative consequences for soil as a habitat. The goal of this study was to evaluate the cumulative after-effect of long-term conventional (CT) and no-tillage (NT) application in combination with or without crop residues on soil physicochemical properties, microbiological activity, and soil respiration (SR) under prolonged dry soil conditions. Long-term CT with residue …

Evaluating Physiological Responses Of Ten Alfalfa (Medicago Sativa Subsp. Falcata) Germplasm To Drought Treatments, Austin Hanson

The Journal of Undergraduate Research

Alfalfa is the most widely produced perennial forage legume in North America. However, its use in the semiarid northern Great Plains is limited due to poor stand establishment and persistence under drought condition. The development of drought-tolerant alfalfa cultivars is of great need. Some Medicago sativa subsp. falcata populations have demonstrated promising drought resistance when compared to M. sativa. Morphological and physiological mechanisms play a critical role in drought tolerance by influencing seedling survival, stand establishment and drought recovery. Assessment of variability in physiological responses to drought among germplasm lines to drought is necessary for developing cultivars with improved drought …

Fertilizers In Aquaculture, Bartholomew Green

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Pond fertilization is an important component of semi-intensive to intensive aquaculture pond management that supports successful production of the culture organism. Semi-intensive and intensive aquaculture pond management fall along the extensive to hyper-intensive management continuum and are characterized by high stocking rate of the culture animal, limited use of fertilizers, use of compound or complete feeds, and water quality monitoring and management, including use of mechanical aeration. Fertilization contributes to establishing and maintaining a pond environment that allows the culture organism to utilize efficiently the compound or complete feeds offered. This chapter presents information on pond food webs, sources and …

Open Access Theses

Three experiments were designed to quantify the nitrogen (N) and amino acid (AA) digestibility of various protein sources fed to growing pigs. The protein ingredients were sunflower meal, cottonseed meal, canola meal, camelina meal, egg albumen, casein, blood meal, plasma meal, potato protein concentrate, soy protein concentrate, soy protein isolate, and linseed meal, which were fed as the sole source of amino acids for the animals and were included in semi-purified, corn starch-based diets. A semi-purified, nitrogen-free diet (NFD) was used to estimate endogenous losses of AA. In each experiment, pigs were surgically fitted with a simple T-cannula at the …

An Evaluation Of Precision Dairy Farming Technology Adoption, Perception, Effectiveness, And Use, Matthew Richard Borchers

Theses and Dissertations--Animal and Food Sciences

Precision dairy farming technologies provide a variety of functions to dairy farmers. Little is known about dairy producer perception of these technologies. A study was performed to understand dairy producer perception of parameters monitored by precision dairy farming technologies. Calving has potential to be predicted using these same parameters and technologies. A second study was performed using two commercially marketed technologies in calving prediction. In order for these technologies to generate accurate and useful information for dairy farm use, they must accurately quantify these parameters. The final study evaluated the accuracy of five commercially marketed technologies in monitoring feeding, rumination, …

Effects Of Post-Hatch Holding Time And Early Nutrition Strategies On Growth Performance, Carcass And Skeletal Characteristics Of Young Chickens, Marquisha A. Paul

Theses and Dissertations--Animal and Food Sciences

The study objectives of this thesis were to evaluate the effects of delayed feeding and specific aspects of the Programmed Nutrition (PN) feeding strategy (Alltech, Inc.) on growth performance, carcass characteristics, and skeletal characteristics of commercial broiler chicks through market age, as well as investigate the effects of breed and the PN feeding strategy on early growth and development. When commercial broiler chicks were fed reduced nutrient diets, delayed feeding decreased early growth performance and carcass yield (P<0.05), whereas post-hatch PN conditioning for 72 hours improved early growth performance and alleviated the negative effects of delayed feeding on carcass yield (P<0.05). Through market age, delayed feeding improved Gain: Feed (P<0.05), while PN had the opposite effect. Interactive effects and main effects of delayed feeding and PN were observed for tissue mineral concentration (P<0.05). PN lowered bone ash % (P<0.05) and increased meat oxidation of broiler chicks during storage (P<0.05). PN also had negative effects on early growth performance and bone breaking strength (P<0.05) of various meat-type breeds, but especially for non-commercial, moderate-growing or fast-growing breeds. In conclusion, PN may be suitable for commercial broiler chicks that experience delayed feeding and are fed reduced nutrient diets.

Turkish Journal of Agriculture and Forestry

The benefits of silicon (Si) in improving crop fitness by biotic and abiotic stress resistance are widely reported. However, investigations about its protective mechanisms for plants facing multiple stresses are very limited. Two contrasting rice cultivars, KS-282 (salt-tolerant) and IRRI-6 (salt-sensitive), were grown in a pot experiment to study the interrelation between Si supplementation (0 and 150 mg kg-1) and boron (B) toxicity (0 and 2.5 mg kg-1) under salinity stress with emphasis on growth response, mineral contents, physiology, and enzymatic antioxidant system response. The results revealed that adverse growth conditions, particularly the combined stress of salinity and B toxicity, …

A Comprehensive Understanding Of Corpse Management In Termites, Qian Sun

Theses and Dissertations--Entomology

Undertaking behavior is the disposal of dead individuals in social colonies to prevent potential pathogenic attack. This behavioral trait has convergently evolved in social insects (primarily termites, ants, and honeybee), and is considered an essential adaptation to social living. In honey bee and ants, workers recognize dead colony members through the postmortem change of chemical profile, and corpses are usually removed out of nest. However, in termites, little is known about the behavioral pattern, chemical cue or molecular basis. In the eastern subterranean termite, Reticulitermes flavipes, this study investigated undertaking behavior toward corpses of different origins and postmortem times. …
