Meat and Milk Institution is implementing red meat sales through grocery chains in order to ensure stability in red meat prices in Turkey. In this study in order to evaluate the effectiveness of this policy from the perspective of consumers, data set obtained from 388 households in Gaziantep city center was used. According to the findings, it has been determined that 53.6% of consumers prefer contracted markets due to the suitability of red meat prices. Initially, all consumers bought red meat from contracted markets, but it was found that 62.11% of them gave up buying red meat from these markets. This situation was found to be quite remarkable and logit model was used to determine the factors affecting the continuity of red meat purchase of households from contracted markets. According to the Logit model results, it was observed that households buying red meat from the contracted markets were affected by the variables that they are care about the price of red meat, income and frequency of shopping at these markets. As a result, it can be stated that this policy implemented by the ESK is aimed at selling red meat to low-income consumers rather than providing price stability and does not have a demand increasing effect.

La agricultura ha progresado ininterrumpidamente, pasando de la utilización de recursos naturales gratuitos al uso creciente de recursos fósiles como fuentes energéticas. Si bien la agricultura depende fundamentalmente de los recursos y servicios del ecosistema, su desarrollo se ha centrado sólo en la producción, sin tomar en cuenta el valor ecológico de las externalidades negativas ni la descapitalización de los recursos que inciden en la sustentabilidad, por lo que la información sobre la evaluación de la sustentabilidad de los diferentes estilos de agricultura es poca o casi nula. En la presente investigación se evaluó la sustentabilidad de los estilos de agricultura (horticultor intensivo, tradicional campesino y horticultor auto sostenible) establecidos en la comuna de Hualqui (Región del Biobío, Chile), mediante los flujos de energía presentes en cada estilo, para medir el impacto que generan sobre el paisaje. Los resultados muestran que el estilo de agricultura horticultor auto sostenible presenta una mayor sustentabilidad en comparación con los estilos tradicional campesino y horticultor intensivo y pueden contribuir a nivel de políticas públicas para reorientar la estrategia de acción y fomentar la sustentabilidad en los distintos estilos de agricultura. ¬¬¬¬ Agriculture has been progressing continuously, from the use of free natural resources to the fossil fuels as energy sources.

Abstract Agriculture has been progressing continuously, from the use of free natural resources to the fossil fuels as energy sources. Even though agriculture depends mainly on ecosystem resources and services, its development has been apparently centered only on yield, not considering neither the ecological value of the negative externalities nor the decapitalization of the resources that influence sustainability. Thus, the information on the evaluation of the sustainability on different agriculture styles is scarce or almost null. This investigation evaluates the sustainability in different agriculture styles (intensive horticulture, traditional farm and self-sustaining horticulture) established in Hualqui (Region of Biobío, Chile), through the energy flows present on each style to measure the impact generated on the land. The results revealed that the self-sustaining horticulture style showed a higher sustainability compared to the traditional farm and intensive horticulture style.

Fruit flies (Diptera: Tephritidae) is one of the most important Diptera families, some species damage fruits, and cause millions of dollars in every years. In this study, adult fruit fly materials were collected from Gaziantep province between 2010 and 2021 from possible host plants using insect net. Obtained materials were examined, and were determined that 15 species. All species recorded for the first time from Gaziantep province. In addition, Goniurellia tridens (Hendel, 1910) recorded as a new record from Turkey. With these contributions, Gaziantep fruit fly fauna increased to 44 species. In the article, examined materials, current list of Gaziantep fruit fly fauna and adult and wing figures of Goniurellia tridens (Hendel, 1910) were given.

This study aims to determine the variation of fiber quality in cotton varieties produced in the Southeastern Anatolia Region and Sanliurfa, Diyarbakir provinces. 1090 fiber samples were obtained from 6 cotton varieties (Lima, Stoneville 468, Candia and Babylon for Sanliurfa, Lima, Stoneville 468, Lodos and Gloria for Diyarbakir) collected from ginning factories in Sanliurfa and Diyarbakir. Statistical analyzes were done with HVI device and obtained data were analyzed by using Excel and TOTEMSTAT programs. In the frequency distribution, cotton varieties of the region are in the medium and long fiber group in terms of fiber length. They were in the medium (only two samples), strong and very strong group in terms of fiber strength. They were generally in the medium and thick group in terms of fiber fineness (micronaire). In terms of fiber uniformity index, the majority of the fibers were in the middle group. In terms of short fiber index, most of the fibers were in the very low and low groups. The majority of the samples were in the high and medium group in terms of fiber elongation, in the mature and very mature group in terms of fiber maturity. In terms of spinning consistency index (SCI) 59,2% of the fibers were between 119,41 and 135,83; 31,3% of them, were between 135,83 and 152,24, 58,2% of the material has a reflectance value of 74 and above. All materials were in white and light-yellow groups in terms of yellowness. It has been observed that the majority of the fibers (66%) are in the low group in terms of trash count. The results obtained from the study of cotton produce of Southeastern Anatolia Region of Turkey has shown that good fiber quality and to meet the demand of textile industry.
