Yield And Fruit Quality Of Sweet Pepper Depending On Foliar Application Of Calcium, Halina Buczkowska, Zenia Michalojc, Renata Nurzynska-Wierdak

Turkish Journal of Agriculture and Forestry

The proper feeding of field plants is one of the most significant factors with an impact on their growth and development. Calcium is one of the basic nutrients of plants, crucial in many cell processes. Calcium in a plant is reutilized very poorly, and hence symptoms of deficiency of this component are observed on the youngest leaves, apexes of stems and roots, and, most importantly, on the fruits. The aim of this study was to evaluate the effects of foliar Ca feeding on the yield of sweet pepper 'Caryca F1' and on selected elements of its fruit quality in field …

Study Of The Effect Of Feeding Highly Digestible Corn Based Calf Starter On The Growth Performance Of Calves, Shruti Srivastava

Electronic Theses and Dissertations

New corn hybrids have been developed by Masters Choice (MC) that vary in energy density and starch digestibility. These MC hybrids have lower starch densities due to an altered starch structure, which allows for greater ruminal and intestinal starch digestion. The altered starch structure of these new hybrids results in reduced feed manufacturing costs (i.e., grinding). Thirty (30) 1 to 3 d old (40.6 ± 1.72 kg) Holstein heifer calves were randomly assigned to 1 of 2 calf starters to measure growth performance of Holstein heifer calves through 8 weeks of age. Treatments were: 1) Hard starch (HS) corn calf …

Expression Of Apoplast-Targeted Plant Defensin Mtdef4.2 Confers Resistance To Leaf Rust Pathogen Puccinia Triticina But Does Not Affect Mycorrhizal Symbiosis In Transgenic Wheat, Jagdeep Kaur, John Fellers, Alok Adholeya, Siva L.S. Velivelli, Kaoutar El-Mounadi, Natalya Nersesian, Thomas Clemente, Dilip Shah

Department of Agronomy and Horticulture: Faculty Publications

Rust fungi of the order Pucciniales are destructive pathogens of wheat worldwide. Leaf rust caused by the obligate, biotrophic basidiomycete fungus Puccinia triticina (Pt) is an economically important disease capable of causing up to 50 % yield losses. Historically, resistant wheat cultivars have been used to control leaf rust, but genetic resistance is ephemeral and breaks down with the emergence of new virulent Pt races. There is a need to develop alternative measures for control of leaf rust in wheat. Development of transgenic wheat expressing an antifungal defensin offers a promising approach to complement the endogenous resistance genes …

Cattle Grazing Effects On Phragmites Australis In Nebraska, Jerry D. Volesky, Stephen L. Young, Karla H. Jenkins Pas

West Central Research and Extension Center, North Platte

Phragmites australis (common reed) is one of the most widely distributed flowering plants in North America. The introduced lineage occurs in wetland and riparian areas covering a range of climatic types. In Nebraska, an abundance of livestock could help to reduce P. australis with proper timing and grazing intensities. In 2011, a 3-yr study was initiated to evaluate targeted cattle grazing and herbicide effects and the nutritive value of this species. Treatments included a single application of imazapyr (Habitatt, BASF Corporation, Research Triangle Park, NC) herbicide applied in the first year, grazing, and a control. Grazing was applied for up …

Food System Education Among High School Students, Yussra Mt Ebrahim

Honors Theses and Capstones

As the American public school system is currently designed, the average student is likely to graduate high school without ever having received any formal instruction regarding the food system in which he or she takes part as a consumer. Such instruction was not necessary up until the current era of separation between consumers and food production. Through this research project, I sought to demonstrate the effectiveness of a single introductory lesson on the issues confronting the modern American food system, which I taught to two high school biology classrooms. A pre-survey was taken by the high school biology students online …

Hormonal And Nutritional Regulation Of Molting, Metamorphosis, And Reproduction In Bed Bugs, Cimex Lectularius, Hemant Gujar

Theses and Dissertations--Entomology

The bed bug, Cimex lectularius is an obligate hematophagous ectoparasite that feeds on humans. The increase in travel and development of insecticide resistance to commercially available insecticides have enabled the bed bug population to resurge, causing economical and psychological trauma to the human population. Lack of knowledge about the basic molecular biology of bed bugs has motivated us to study the key aspects of molting, metamorphosis, and reproduction. A blood meal triggers expression of various genes that enable bed bugs to molt or undergo metamorphosis. Molting and metamorphosis in bed bugs are regulated by two key hormones: 20-hydroxyecdysone (20E) and …

The Chemical Ecology Of Bed Bugs (Cimex Lectularius, L.) And The Impact Of A Neurotoxic Insecticide On Physiology And Behavior, Sydney E. Crawley

Theses and Dissertations--Entomology

Following a decades-long hiatus in many nations, populations of bed bugs (Cimex lectularius) have rebounded and are thriving on a global scale posing substantial challenges for pest management professionals. Insecticide resistance to both pyrethroid and neonicotinoid compounds has been identified in many populations, leading to renewed interest in alternative control methods for management of this pest. The objectives of my dissertation research were to study various, typically cryptic, bed bug behaviors in order to improve both conventional and alternative management strategies. Novel behavioral interactions among mother and offspring were characterized. Additionally, changes in behavior and physiology after treatment …

Regional Variations Of Optimal Sowing Dates Of Maize For The Southwestern U.S., Boksoon Myoung, Seung Hee Kim, Jinwon Kim, Menas Kafatos

Mathematics, Physics, and Computer Science Faculty Articles and Research

Sowing date (SD) is sensitive to regional climate characteristics; thus, it is critical to systematically examine the effects of SD on crop yields for various temperature regimes. We performed a sensitivity study of SD for maize in the southwestern U.S. using the regionally extended version of the Agricultural Production Systems sIMulator (APSIM) model. The model was run utilizing North American Regional Reanalysis at a 32 km resolution from 1991 to 2011, with an irrigation threshold at 95% of the soil water-holding capacity. Two types of SD optimizations maximizing yield potential (Yp), varying spatially or interannually, revealed that the optimal SD …
