Siberian Elm Responses To Different Culture Conditions Under Short Rotation Forestry In Mediterranean Areas, Ignacio Pérez, Javier Pérez, Juan Carrasco, Pilar Ciria
Turkish Journal of Agriculture and Forestry
This work explores the possibilities of biomass production, for energy purposes, of Siberian elm in Mediterranean areas, including marginal lands with poor soil and low water availability. To achieve this, the influence of soil type, planting density, and water availability on biomass production were analyzed after the first 3 years of the growing cycle in 2 different locations. Moreover, a method to estimate biomass production as a function of some morphological parameters of the trees, as well as the use of leaf water potential as a good indicator of trees' water status, are discussed. The analysis of parameters having an …

An ideal veneer surface is crucial for good panel properties in plywood manufacturing. The aim of this study was to compare plasma treatments and sanding (mechanical) processes with respect to the surface roughness of veneers. Rotary-cut veneers with a thickness of 2 mm from Scots pine (Pinus sylvestris) logs were used as material. After rotary peeling, veneer sheets were dried at 110 °C in a veneer dryer. Veneer sheets were divided into 4 main groups. The surfaces of the control veneer sheets were left untreated. Two different grits of sandpaper, 80 and 180, were used for sanding the surfaces of …

Smart Biologics For Crop Protection In Agricultural Systems, Ömür Baysal, Mahmut Tör
Turkish Journal of Agriculture and Forestry
Crop losses caused by insects, pests, and pathogens remain one of the major problems in sustainable agriculture. Environmental and health concerns regarding the overuse of pesticides, and the impacts of climate change on epidemics are immediate pressing issues. In addition, the breakdown of plant resistance by pathogen populations brings limitations to the genetic control of diseases. Biologics can be effective in all types of agricultural systems including organic, sustainable, and conventional. Beneficial microorganisms including Bacillus and Trichoderma species have been employed as environmentally safe biopesticides. Molecular and proteomic studies on biopesticides have revealed the nature of antibiotics, secreted enzymes, and …

The Application For Fertilizer-Yield Relationships Of The Et-Yield Response Factor Equation, Ahmet Ertek
Turkish Journal of Agriculture and Forestry
Many attempts have been made to understand the plant response to water using plant growth models. The effects of fertilizer on crop yield are greater than those of water. Therefore, some models that have been developed for the evaluation of water-yield relationships can also be used for fertilizer-yield relationships. The purpose of this study was to develop an equation to use in fertilizer applications similar to one used to evaluate crop production under adequate and deficit water supply regimes. The equation can be rewritten for the fertilizer consumed by plants instead of the evapotranspiration (ET). Sample applications showed that the …

International Perspectives On Sustainable Agriculture In Cuba, B. Danielle Smith
University Honors Theses
Since the economic crisis following the collapse of the Soviet Union, Cuba has restructured their agriculture with a greater focus on domestic production of domestically consumed produce, and a dramatic reduction of petroleum products in all aspects of food production. This overhaul has included the broad application of what is termed agroecology – agricultural practices which focus on principles of biodiversity and sustainability – and inter-farm cooperation facilitated by the National Association of Small Farmers (ANAP) and Campesino a Campesino. Academics and journalists from within and abroad have critically examined aspects of the novel reforms developed in the country …

Turkish Journal of Agriculture and Forestry
The present study was carried out to determine the effects of methyl jasmonate (MeJA) treatments on the fruit peel color parameters, anthocyanin content, ethylene biosynthesis, phenolic content, and antioxidant capacity of Braeburn apples. Experimental trees were treated with 1120, 2240, or 4480 mg L-1 MeJA at 1- and 2-week intervals between the 105th and 175th days of growth after full bloom. L* and hue decreased linearly with increasing MeJA concentrations in both experimental years. While MeJA treatments did not cause significant changes in chroma, except for in the final harvest in 2010, it decreased chroma values significantly on all sampling …

Phosphorus (P) loss from agricultural watersheds has long been a critical water quality problem, the control of which has been the focus of considerable research and investment. Preventing P loss depends on accurately representing the hydrological and chemical processes governing P mobilization and transport. The Soil and Water Assessment Tool (SWAT) is a watershed model commonly used to predict run-off and non-point source pollution transport. SWAT simulates run-off employing either the curve number (CN) or the Green and Ampt methods, both assume infiltration-excess run-off, although shallow soils underlain by a restricting layer commonly generate saturation-excess run-off from variable source areas …

Switchgrass (Panicum virgatum) is a polyploid, outcrossing grass species native to North America and has recently been recognized as a potential biofuel feedstock crop. Significant phenotypic variation including ploidy is present across the two primary ecotypes of switchgrass, referred to as upland and lowland switchgrass. The tetraploid switchgrass genome is approximately 1400 Mbp, split between two subgenomes, with significant repetitive sequence content limiting the efficiency of re-sequencing approaches for determining genome diversity. To characterize genetic diversity in upland and lowland switchgrass as a first step in linking genotype to phenotype, we designed an exome capture probe set based on transcript …

Mycobacterium avium subsp. paratuberculosis causes Johne’s disease (JD) in cattle, sheep, goats, and other ruminant animals. JD presents as a chronic granulomatous intestinal infection with a worldwide distribution and imposes a significant economic toll on livestock industries (1). M. avium subsp. paratuberculosis has a complex cell wall structure containing mycolic acids and several lipids similar to those of other members of this genus, yet it is the most slowly growing member. This bacterium often requires 8 to 16 weeks before colonies are visible in culture, which is a major hurdle in diagnostics and therefore in the implementation of optimal JD …

Mycobacterium avium complex (MAC) organisms cause opportunistic infections in humans, yet their epidemiology remains poorly understood. They are slowly growing environmental and animal-associated mycobacteria that have little notoriety except for the strains that cause disseminated infections in HIV- infected humans (1). Most MAC organisms are classified taxonomically as a single species, M. avium, which is divided into at least four subspecies, M. avium subsp. avium, M. avium subsp. hominissuis, M. avium subsp. paratuberculosis, and M. avium subsp. silvaticum (2). The only other species in this group is M. intracellulare. Genotyping of this diverse bacterial group has been achieved using intergenic …

Background: Transgenic corn hybrids that express toxins from Bacillus thuringiensis (Bt) have suppressed European corn borer populations and reduced the pest status of this insect throughout much of the US corn belt. A major assumption of the high-dose/refuge strategy proposed for insect resistance management and Bt corn is that the frequency of resistance alleles is low so that resistant pests surviving exposure to Bt corn will be rare. Results: The frequency of resistance to the Cry1F Bt toxin was estimated using two different screening tools and compared with annual susceptibility monitoring based on diagnostic bioassays and LC50 …
