International Migration, Xenophobia and Migrant Employment in Rural Areas: Konya Example Full text
2024
Merve Bozdemir Akçil | Zeki Bayramoğlu
This study examines the problems arising from that the agricultural sector has become a significant employment area for migrant labor due to migrant migration. The presence of migrant labor in the agricultural sector has increased because of the cost advantages provided by agricultural operators of cheap labor supply despite informal working conditions. Migrant labor has crucial contributions to the sustainability of production activities, especially in the agricultural sector, where the local labor does not want to be employed. However, the perspective of local people toward migrants differs over time, especially due to different social and cultural characteristics. Since these differences are more noticeable in small settlements, such as rural areas people who are migrant to society or national identity become unwanted in the living spaces of local people over course of time, this study aimed to determine the perspective toward migrant labor and to evaluate the impact of this situation on the sustainability of production. In line with the results obtained, policy recommendations were made for the integration of migrant labor and the planning of agricultural activities.

Rıdvan Bayram | Hasan Çelikyürek | Hasan Koyun
Many scientific studies are conducted directly or indirectly with humans, animals, and plants. We believe that body electricity, which is generated and constantly present in the bodies of living beings, should be considered in scientific studies as an effective factor for production activity. We believe that body electricity should be included in the environment to bring the rumen fluids of sheep used in Daisy II rumen simulators closer to reality. In this way, the most realistic environment is created by adding the influencing factors of body electricity and many factors that can affect the outcome. The study was conducted on a total of 16 Karayaka ewes, including 4 lambs, 4 one-year-old ewes, 4 pregnant ewes and 4 lactating ewes. The data obtained in the study were collected by measuring the body electricity of the animals before and after grazing in 3 different periods for each group. At the end of the study, it was found that the value of body electricity of sheep determined at 0.12±0.001 v (volt) before feeding was higher than the value determined at 0.09±0.002 v after feeding. The difference between the two values was found to be statistically significant (P<0.05). However, it was found that the fact that the live weights of the animals in the groups were different and they were in different physiological periods did not cause a significant (P>0.05) difference in the electrical body currents before and after feeding (except in lambs (P<0.05)). It can be said that the measurements made in other periods and groups can change the electrical body currents after feeding and that the electrical body currents differ according to the animals fed in the barn, especially during the grazing period, before going to pasture and when returning to pasture.

Elif Tuğçe Bozduman
The increase in the volume of foreign trade between Türkiye and MERCOSUR countries in recent years has an important potential. The fact that these countries are economically similar further increases the mutual foreign trade potential. These trade relations are important in terms of economic cooperation and are expected to strengthen the economic interests of countries over time. Both Türkiye and MERCOSUR countries have a high potential in terms of production and foreign trade in agricultural and livestock products. Of course, the fact that countries are members of the World Trade Organization has increased free foreign trade in these sectors. Therefore, in this study, the level of foreign trade specialization in the agriculture and livestock sector after Türkiye and MERCOSUR countries became a member of the World Trade Organization was analysed. In this study covering the years 1995-2022; Net Trade, Export-Import Ratio, Lafay and Michaely indices were used. The findings show that the highest specialization is in Argentina and the lowest in Paraguay. In addition, Türkiye and Brazil have an advantage in numerically similar product groups. Türkiye needs to increase productivity in agriculture to increase the level of specialization in foreign trade.

La deficiencia de vitamina A es un problema de enormes consecuencias en la salud pública de muchos países en desarrollo. El perfeccionamiento y difusión de variedades con altos contenidos de carotenoides provitamina A es una estrategia para resolver este problema. La yuca es un cultivo relevante en muchas regiones del mundo cuyos habitantes padecen deficiencia crónica y generalizada de vitamina A. A pesar de que se ha logrado incrementar significativamente el contenido total de carotenoides (CTC) en raíces de yuca mediante el mejoramiento genético, es poco lo que se conoce sobre la herencia de CTC. En este estudio se analizaron numerosas familias de hermanos completos y S1 (resultantes de autofecundaciones). La heredabilidad, estimada por regresión padre-progenies, resultó ser alta (> 0.60) y el análisis de las segregaciones no permitió definir patrones de segregación mendeliana simple que explicaran la variación en todas las familias. Sin embargo, hay suficiente evidencia para plantear la hipótesis de que la herencia es relativamente simple y depende de dos o tres genes mayores, cuya expresión es afectada por unos pocos genes modificadores menores. Se propone que al menos uno de los genes mayores inhibiría la acumulación de carotenoides. | Vitamin A deficiency (VAD) is a major problem with huge public health implications. One strategy to overcome this problem is the development of varieties with increased levels of pro-vitamin A carotenoids. Cassava is a relevant crop in many regions of the world where VAD is prevalent. Significant progress has already been achieved increasing the content of total carotenoids (CTC) in cassava roots. However, little is known on the inheritance of this trait in cassava. In this study the segregations for CTC in several full-sib and self-pollinated (S1) families were analyzed. Parent-offspring regression was used to estimate heritability, which was found to be high (>0.60). The analyses of segregations did not allow for the identification of simple Mendelian patterns that could explain the variation in CTC in every family analyzed. However, enough evidence has been generated for a hypothesis that few (2-3) major genes control most of the variation in CTC but their action is modified by few minor genes. Mounting evidence was also found that at least one single dominant gene may inhibit carotenoids accumulation in the roots.

Eylem Ezgi Fadıloğlu | Haluk Ergezer
The study was carried out to develop chicken patties by incorporating acorn flour as a meat replacer at 3%, 6%, and 9% levels in the formulation. For this purpose, the chemical (moisture, protein, fat, ash), pH, thiobarbituric acid (TBA), and color analyses in the raw and cooked chicken patties were analyzed. In addition, the cooking properties (cooking yield, diameter reduction, thickness reduction), functional properties (moisture and fat retention) and sensory properties were examined on cooked chicken patties. There were significant changes in the chemical, cooking, functional, and color properties of chicken patties with acorn flour. The moisture and protein values decreased, in both raw and cooked samples incorporated with acorn flour but fat level increased only in raw acorn flour added samples. Lightness (L*) and redness (a*) values decreased significantly. The addition of acorn flour caused an increase in b* values of raw samples and a decrease in cooked samples. Acorn flour was not effective in preventing lipid oxidation. The addition of acorn flour contents in chicken patties improved functional and cooking properties, decreased cooking loss, and increased moisture and fat retention. The use of acorn flour improved the quality parameters of patties, but the addition of acorn flour resulted in a darker color in patties. The use of acorn flour in chicken meatballs did not negatively affect sensory properties except color. In conclusion, acorn flour can be used as a filler and binder in chicken patties.

Las fracciones de materia orgánica del suelo (MOS) lábiles y humificadas pueden ser afectadas por las prácticas de uso y manejo; sin embargo el impacto de estos cambios no se ha evaluado en suelos y ambientes tropicales. El presente estudio tuvo como objetivo evaluar los contenidos y algunas formas de carbono orgánico del suelo (COS) en cinco zonas de clima cálido tropical (0 - 1110 m.s.n.m.) del departamento del Magdalena (Colombia) y el efecto que sobre ellas han tenido las prácticas asociadas a suelos cultivados con café (Coffea arabica), banano (Musa sp.), palma africana (Elaeis guineensis) y sábila (Aloe vera), comparados con suelos de bosques naturales. No se encontraron diferencias (P < 0.05) tanto entre zonas como entre usos del suelo, se presentaron valores medios a bajos de MOS en las zonas de estudio y contenidos de carbono total (Ct) mayores en suelos de bosques que en suelos cultivados, así los suelos de bosques presentan una acumulación media de Ct de 42.4 mg/ha a 20 cm, frente a 33.8 mg/ha en los suelos cultivados, esto equivale a una pérdida media de Ct del 23% por efecto del manejo de los cultivos. En relación con el carbono extraíble con pirofosfato sódico altamente relacionado con las fracciones humificadas de la MOS (Cp) se observaron valores muy bajos en los suelos cultivados y casi nulos en suelos de bosques; sin embargo estos últimos presentan mayor contenido de formas de carbono no-oxidables o estables (Cnox) determinado por diferencia entre Ct - carbono oxidable (Cox). En el suelo cultivado con banano, el Ct corresponde en su totalidad a formas de Cox; mientras que en el suelo cultivado con palma africana las formas estables Cnox representaron 83% del carbono total. | Fractions of soil organic matter (SOM) labile and humified, can be affected by use and management practices, but the impact of these changes has not been evaluated in soils of tropical environments. The present study investigated the contents and some forms of soil organic carbon (SOC) in five warm tropical climate zones of the Department of Magdalena (Colombia), and the effect of the cropping practices on these forms of organic carbon in cultivated soils, associated with Coffee (Coffea arabica), Banana (Musa sp.), African palm (Elaeis guineensis), Aloe (Aloe vera) compared to natural forest soils. Significant differences (P < 0.05) were not found between zones as much use soil as. Low average values of SOM in the study areas and higher contents of total carbon in forest soils than in cultivated soils were reported. Forest soils had an average carbon accumulation total of 42.4 mg/ha at 20 cm, compared to 33.8 mg/ha in the cultivated soils, this equates to an average loss of 23% total C by the effect of crop management in these soils, compared to C humified (C extracted with sodium pyrophosphate), values are observed very low in cultivated soils and almost zero in forest soils, but forest soils had a higher number of stable forms of C (Cnox). In the soil cultivated with bananas, Total Carbon corresponds to fully oxidized forms of C, however in the soil cultivated with African palm, C stable forms represented 83% of total carbon.

Beril Kocaman
Strawberry (Fragaria × ananassa Duch.) is one of the most widely consumed and cultivated fruits worldwide. Sorbitol plays a role in plant responses to many biotic and abiotic stresses. In this research, we intended to understand the effect of sorbitol spraying on the bioactive compounds of strawberry leaves. The application of sorbitol at different concentrations (0, 25, 50 mM and 75 mM) greatly improved strawberry characteristics such as total chlorophyll, chlorophyll a and b, carotenoids, and total phenolics. As sorbitol concentrations increased, chlorophyll a and chlorophyll b values increased in the samples taken during the fruiting period and higher values were obtained. The carotenoid content increased by approximately 189.49% and the total phenolic content increased by 30.85% in strawberry plants treated with sorbitol compared with the control. Supply of sorbitol decreased flavonoid content. The results indicate that sorbitol treatment has no inhibitory influence on the overall growth of strawberries. Among the biochemical parameters analyzed, chlorophyll, phenolic, and carotenoid contents increased, whereas flavonoid content decreased with sorbitol application.

Fatma Zehra Ok | Arif Şanlı
Bu çalışma, farklı dozlarda Gibberellik asit (GA3) uygulamalarının patateste yumru verimi, kalitesi ve dormansi süresi üzerine etkilerinin belirlenmesi amacıyla yürütülmüştür. GA3 uygulamalarına (0, 50, 100 ve 200 mg/L GA3) dikimden 45 gün sonra (çiçeklenme öncesi dönem) başlanarak 15 gün aralıklar ile 4 farklı dönemde yapraklara püskürtme şeklinde yapılmıştır. Çalışmada GA3 uygulamaları ile birlikte ocak başına yumru sayısında % 56, yumru veriminde ise % 36’ya varan artış meydana gelmiş, ortalama yumru ağırlığı ve pazarlanabilir yumru oranları ise önemli derecede azalma göstermiştir. En yüksek yumru verimi dikimden 75 gün sora yapılan 100 ve 200 mg/L GA3 dozlarından elde edilmiştir. GA3 uygulamaları yumrularda şekil bozulmalarına yol açmış, genel olarak doz artışı ile birlikte çatlak yumru oranı ve sekonder gelişme gösteren yumru oranı artmıştır. GA3 uygulamaları yaprak klorofil içeriği (SPAD değeri) ile yumru kuru madde oranının azalmasına neden olmuştur. Kontrolde ortalama 110 gün olan dormansi süresi dikimden 90 gün sonra yapılan 200 mg/L GA3 uygulamaları ile 80 güne kadar kısalmıştır. Çalışmada, tohumluk amacıyla yapılacak üretimlerde yapraktan yapılan GA3 uygulamaları ile patateste yumru sayısı ve veriminin önemli derecede arttırılabileceği ve yumruların hasat sonrası depolama devresinde dormansi sürelerinin kısaltılarak özellikle ikinci üretimler için avantaj sağlanabileceği anlaşılmıştır.
