Genome Scale Comparison Of Mycobacterium Avium Subsp. Paratuberculosis With Mycobacterium Avium Subsp. Avium Reveals Potential Diagnostic Sequences, John Bannantine, Emily Baechler, Qing Zhang, Lingling Li, Vivek Kapur

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

The genetic similarity between Mycobacterium avium subsp. paratuberculosis and other mycobacterial species has confounded the development of M. avium subsp. paratuberculosis-specific diagnostic reagents. Random shotgun sequencing of the M. avium subsp. paratuberculosis genome in our laboratories has shown >98% sequence identity with Mycobacterium avium subsp. avium in some regions. However, an in silico comparison of the largest annotated M. avium subsp. paratuberculosis contigs, totaling 2,658,271 bp, with the unfinished M. avium subsp. avium genome has revealed 27 predicted M. avium subsp. paratuberculosis coding sequences that do not align with M. avium subsp. avium sequences. BLASTP analysis of the 27 predicted …

Production Of Dissolving Grade Pulp From Poplar Wood By Ethanol-Water Process, Hüseyi̇n Kirci, Mehmet Akgül

Turkish Journal of Agriculture and Forestry

The possibilities of dissolving grade pulp production from poplar by an ethanol-water process were investigated. The effects of ethanol ratio, cooking temperature and acid catalyst ratio on unbleached, bleached and alkali-purified pulps were studied. It was seen that catalyst ratios exceeding 0.01% caused serious yield and viscosity losses. The results showed that with the catalyst ratio to pulping liquor exceeding 0.01%, pulp yield and viscosity were reduced to an unacceptable level. The best pulping result was obtained at 40% ethanol consistency, 180 ºC pulping temperature and 150 min reaction time without the addition of acid catalyst to the pulping liquor. …

Effects Of Pruning Treatments On The Yield And Fruit Quality Of Precoce De Tyrinthe Apricot Cultivar, Levent Son, Ali̇ Küden

Turkish Journal of Agriculture and Forestry

This study was carried out to determine the effects of pruning on the yield, fruit quality and phenological aspects of three year-old trees of the Precoce de Tyrinthe apricot cultivar grown in Mut-Mersin. In the first experimental year, unpruned trees were found to be more productive; however, these trees gave lower yields (6.5 kg/tree) in the second year due to alternate bearing. August+winter (12.0 kg/tree), July+winter (10.4 kg/tree), and September+winter (10.1 kg/tree) pruning applications were more productive than control trees (6.50 kg/tree). The fruit size of the control trees was 34.05 g, while September+winter (45.66 g), August+winter (44.70 g), and …

An Economic Analysis Of Pre-Harvesting Marketing Strategies And Financial Performance, Manuel Duarte Filipe

LSU Master's Theses

Risk is an important concern in the management of a farm business. The rising input prices along with the variability in the farm commodity prices may result in a risk environment. Government programs have generally provided income support to farmers. However, there has been considerable discussion regarding this support in recent years. The farm act of 2002 and farm bill of 1999 are good examples of such discussions. These uncertainties emphasize the need to improve information for farm's income risk management, and make some one ask if there is not out there any alternative way of managing income risk besides …

LSU Master's Theses

The alternative rough rice marketing and storage strategies were evaluated using three methods of analysis. The methods used in this study were MOTAD, simulation, and stochastic dominance. Historical rough rice prices from 1980/81 - 2000/01 was used and tested for trends and seasonality in order for the methods to be formed properly. SAS was used to verify that the data used in this study did not follow any time trend or reflect seasonality. MOTAD, simulation, and stochastic dominance were used to determine the most efficient marketing and storage strategy that will enable rice farmers to make the best decisions and …

Effects Of Girdling, Ga3 Applications And Additional Nutrient Applications On Fruit Yield, Fruit Set And Fruit Size In The Clementine Mandarin, Turgut Yeşi̇loğlu, Ebru Cücü Açikalin

Turkish Journal of Agriculture and Forestry

In small fruit species, like the mandarin, fruit size is lower in Turkey than in other countries and this has a negative effect on their marketing. There are problems with fruit yield and size in the Clementine mandarin, which is a commonly grown mandarin cultivar in Turkey. To solve these problems, various studies have been carried out. Girdling is one of the methods studied and it had positive effects on fruit yield and size without lowering the fruit quality. However, fruit yield and fruit size were reduced to previous levels if the treatment was repeated over a long period. In …

Quantitative Determination Of Alkyl Ketene Dimer (Akd) Retention In Paper Made On A Pilot Paper Machine, Ari̇f Karademi̇r

Turkish Journal of Agriculture and Forestry

There have been some problems reported associated with the use of alkyl ketene dimer (AKD) in alkali papermaking. Excessive use of size emulsion, poor size performance when filler used, problems with back water contamination, poor retention, and formation of pitch deposits on machinery are some of the problems experienced during papermaking operations. In addition, paper containing AKD is reported to lose its resistance, over time against liquid penetration and tends to become slippery. Therefore, in this study, the retention and reaction mechanisms of AKD internal sizing agent in a paper matrix were investigated by capillary gas chromatography (GC) in an …

Comparison Of Erosion And Runoff Predicted By Wepp And Agnps Models Using A Geographic Information System, Hali̇l Kirnak

Turkish Journal of Agriculture and Forestry

The Water Erosion Prediction Project (WEPP) model and the Agricultural Non-Point-Source Pollution Model (AGNPS) were used in conjunction with a geographic information system (GIS) database to predict runoff and sediment discharges for Rock Creek watershed, an agricultural watershed in Ohio, USA. Observed and predicted values were compared for selected storm events in 1988 and 1990. The statistical evaluation of the WEPP and AGNPS models showed that WEPP predicted average runoff, peak runoff and sediment yield better than AGNPS. WEPP and AGNPS overpredicted peak runoff rates compared to observed data by 15.5% and 26.5%, respectively. The t-test showed that there was …

Additive Main Effects And Multiplicative Interactions Analysis Of Yield Performances In Bread Wheat Genotypes Across Environments, Yüksel Kaya, Çeti̇n Palta, Seyfi̇ Taner

Turkish Journal of Agriculture and Forestry

This study was carried out to determine the yield performances of 20 bread wheat genotypes across six environments in Central Anatolia, Turkey, in the 2000-2001 growing season. The experimental layout was a randomized complete block design with four replications. Additive main effects and multiplicative interactions analysis (AMMI) indicated that the yield performances of genotypes were under the major environmental effects of genotype by environmental interactions. The first two principal component axes (PCA 1 and 2) were significant (p < 0.01) and cumulatively contributed to 78.64% of the total genotype by environment interaction. A biplot generated using genotypic and environmental scores of the first two AMMI components also showed that genotypes with larger PCA 1 and lower PCA 2 scores gave high yields (stable genotypes), and genotypes with lower PCA 1 and larger PCA 2 scores had low yields (unstable genotypes), as in the sites tested.

Seasonal Carbohydrate Changes Of The Bark Tissues Of Hazelnut Cultivars Grown In The East And West Black Sea Region, Yeşi̇m Okay, A. İlhami̇ Köksal, Nevzat Artik

Turkish Journal of Agriculture and Forestry

The seasonal changes in total carbohydrate, fructose, glucose and sucrose levels of bark tissues of the Tombul, Palaz, Kalınkara, Çakıldak and Sivri cultivars grown in the East and West Black Sea regions were determined by high performance liquid chromatography (HPLC). As with other fruit species, carbohydrate levels decreased from the end of spring to summer, showed steady changes with low values in summer and increased starting in the middle of fall until winter. Despite a general tendency of decline during spring, the carbohydrate and soluble sugar contents of Sivri increased in the Düzce region in April. Annual changes in carbohydrates …

Botrytis In Wine Grapes In Western Australia, Diana Fisher, Colin Gordon, Peter Wood

Bulletins 4000 -

Botrytis, causal agent Botrytis cinerea, is a fungal disease of grapevines that is commonly referred to as Botrytis bunch rot or grey mould. Botrytis is most prevalent where warm, wet conditions are frequent, but symptoms can occur in cool, wet weather and high humidity. All grape varieties are susceptible. Varieties most at risk are those with berries that are thin-skinned and/or have tight bunches.

Some white wine grape varieties infected with Botrytis may decay, in certain conditions to produce noble rot . Wine produced from these infected bunches produce unique aromatic characters with high residual sugar and are …

Organic Beef A Production Guide, Steven Mccoy

Bulletins 4000 -

Premium markets are expanding worldwide for certified organic and biodynamic beef products – those grown in accordance with recognised organic production and processing standards.

Many agricultural areas in Australia have the potential to produce organic beef, and several Western Australian and Eastern States organic producers are already exporting to Japan. Supermarkets such as Coles and Woolworths have started to build the Australian domestic market.

Converting to an organic system can be easier - requiring fewer changes - in ‘low input’ rangeland cattle production than in more intensive pasture-based or feedlot production. But regardless of the type of enterprise, managing organic …
