Platform
Authors: Melda AÇMAZ ÖZDEN; Emre ÖZELKAN
Abstract: While cities are facing challenges such as uncontrolled growth, population growth, and climate change, environment and human-friendly solutions are sought to create more livable urban areas. Green areas in cities play an important role in improving the quality of life quality of life for residents and reducing the risks of the disasters. Urban green area planning is a holistic and strategic process in which qualitative and quantitative factors should be considered in detail. This study focuses on determining the qualities and potentials of urban green areas in the city center of Çanakkale province in western Turkey and determining the amount of green area per capita, which is one of the quantitative factors. In addition, the study also aims to draw conclusions about the distribution and accessibility of urban green areas. Determining the amount, accesibility and distribution of active green areas, which are intensively used by urban dwellers for recreational purposes and are the determinants of the presence of green area in the city, is important in terms of forming the basis for strategies that improve urban quality of life. In this study, the active green areas in various urban landscapes were determined by utilizing high spatial resolution satellite remote sensing images and the spatial distribution and accessibility analysis were performed in a geographic information systems (GIS) platform. The findings of this study provide a basis for the development of local green area strategies and contribute to the current discourse on livable and sustainable urban development.

- A Place Proposal for Shinrin-Yoku (Forest Bath): Günlüklü
Bay Sweetgum Forest
Authors: Zeynep R. ARDAHANLIOĞLU
Abstract: Located in the borders of Fethiye district of Mugla province, the Günlüklü Bay is located on the Fethiye-Mugla highway and 17 km from the city center of Fethiye. The Günlüklü Bay, takes its name from the Günlük, that is, Sweetgum (Liquidamber orientalis) tree located within the borders of the bay. Sweetgum trees are endemic and long-lived trees that have survived from the ice age to the present day. Sweetgum trees show their widest distribution around Mugla in Turkey. In recent years, especially after the pandemic, the need for areas that integrate people with nature and where people will feel more peaceful in every respect has increased. With shinrin-yoku practice, the person rests his body and mind with long and calm walks in the forest. In this study, it is suggested that the sweetgum forest in the Günlüklü Bay of Fethiye, which is an important tourism center, should be evaluated for shinrin-yoku (forest bath). As a method in the study, firstly a literature review was made and then field analysis was made and suggestions were made about the applicability of shinrin-yoku (forest bath). As a result, it was emphasized that a different experience for both the local people and the local and foreign tourists coming to the region and the sustainable use of Günlüklü Bay, which is home to sweetgum trees, is made to be evaluated outside of mass tourism activities.

- The perceptions of Siirt University students on the definition and
functionality of "ornamental plant"
Authors: Arzu ÇIĞ; Nazire MIKAIL
Abstract: In this study, in the year 2019, the perception of the definition and functionality of ornamental plants of the students studying at Siirt University, which is located in the province of Siirt in the Southeastern Anatolia Region and is the only higher education institution in the province, was tried to be measured. For this purpose, 304 students selected by simple random sampling method were surveyed. The research subject of the questionnaire consisting of 47 questions is to determine the recognition of ornamental plants by Siirt University students, their thoughts and expectations about their functions and usage areas. According to this study, which was carried out to draw attention to ornamental plants, which are not grown and consumed / used as much as other agricultural products due to the socio-economic situation of the people of the region, the majority of the students did not grow or buy ornamental plants beforehand. 32.1% of the students did not buy because they were uninterested and 22.6% did not have enough information about plants. About 65% of the buyers made a purchase once a year. Florists are preferred for purchase. On special occasions and celebrations, the most demanded are potted and flowering plants and cut flowers such as bouquets/bundles. During the cemetery visit, 39.4% of the students prefer perennial plants such as pine and rose, which are outdoor ornamental plants, and those who prefer cut flowers are 27.1%. Most of the students understood potted plants, potted flowering plants, flowering bulbous plants, cut flowers, dried flowers and artificial-plastic flowers under the concept of ornamental plants, and excluded tree and shrub saplings from this perception. Additionally, they did not agree with this definition, ignoring the fact that ornamental plants bear fruit, grow rapidly and create shade.As a result of this study, it has been tried to determine the perceptions and awareness of the students who make up the young population that will affect the use and purchase of ornamental plants. It is thought that the academically conscious young people will reconsider their attitudes when they reach a sufficient socioeconomic and sociocultural level, and the ornamental plant sector in the region will develop a strategy according to the trends in production and sales.

- The Effects of Agricultural Support and Government Stability on
Agricultural Value Added: A Panel Data Analysis on Developing Countries
Authors: Şerife ÖZŞAHİN; Cansu GÜVEN
Abstract: The agricultural sector has been one of the important occupations in every period of history, with its feature of meeting the nutritional needs of the population living in the country. It is stated that the agricultural sector has strategic importance as it provides raw materials for the industry, contributes to export revenues, provides employment and income opportunities for the people living in the country. Although the contribution of the agricultural sector to GDP has tended to decrease with the industrialization process, it is known that the sector maintains its importance in every period due to its connection with other fields of activity. This study tries to investigate the effects of agricultural supports and government stability on agricultural added value in 6 developing countries with the highest agricultural production value worldwide in 2018 according to FAO data. In this direction, based on the existing literature, an econometric model has been established with agricultural employment, per capita income, width of agricultural lands and import of agricultural raw materials as an explanatory of agricultural value added. Findings from static panel data analysis show that agricultural employment, government stability, agricultural land size and agricultural raw material imports have positive effects on agricultural value added, while per capita income has negative effects. Although the effect of agricultural support given to producers on agricultural value added is positive, it is not statistically significant.

Abstract: The study aims to determine the efficiency of input use and to analyze the factors affecting technical efficiency in farms producing maize. Maize is among the most cultivated cereals in the world. Konya, on the other hand, ranks first in Turkey with a 10% share in maize production. The research area of Cumra district, which constitutes 15.76% of the maize production in Konya province, has been selected according to the purposive sampling method. In the study, the sample volume was determined as 77, with a 95% confidence interval and a 5% margin of error, according to the stratified sampling method. In the study, linear regression analysis was carried out to determine the factors affecting the technical efficiency of maize producers. According to the results of the research, gross production value (USD), total land size (ha), and age were found to be statistically significant at the 5% significance level. Variable costs and education were statistically significant at the 10% significance level. The DEA method, which is a non-parametric method, was used to determine the technical efficiency and scale efficiency of farms under the assumption of technical efficiency, VRS, and CRS. Farms should be informed about the optimum use of inputs. In addition, a farmer training program to be organized on this subject should be given to the farmers.

- Investigation of the Stem and Leaf Anatomy of Five Artemisia L. Species
Growing in Türkiye
Authors: Ş. Rumeysa OSMANLIOĞLU DAĞ; Murat KÜRŞAT, Ayşe Mine GENÇLER ÖZKAN, İffet İrem ÇANKAYA
Abstract: In this study, it is aimed to make anatomical analysis of five different Artemisia L. species (A. absinthium L., A. annua L., A. abrotanum L., A. incana (L.) Druce, A. tournefortiana Rchb.) grown in Turkey and contribute to the definition of this genus, which has some taxonomic problems. The materials for anatomical study were preserved in 70% alcohol. Free hand cross sections were taken using sharp razor blades, stained and mounted in Sartur Reagent and Chloralhydrate (50%) solution. Anatomical structures of the stem and leaf of selected species were examined under the light microscope. Their detailed structures were illustrated with photographs. Results have shown that stem and leaf anatomical features of the Asteraceae family are mostly shared by all species. However, some characters could be considered species-specific. In cross- sections, the stems of all studied species have more or less irregular rounded shapes, but prominent ribs containing collenchyma tissue could be noticed only in A. annua stem. The leaves of A. absinthium and A. incana were covered by glandular and densely T-shaped non--glandular trichomes on both sides however, A. tournefortiana had no hair at all. There were highly apparent secretory canals located in both the stem (next to the endodermal cells) and the leaf (near to xylem) of A. tournefortiana. The anatomical structure of leaves and stems of A. tournefortiana and A. incana growing in Turkey was demonstrated for the first time. Our results revealed that the studied species are anatomically distinguishable from each other and also provided valuable features for better species identification and contribute to the anatomy of the genus Artemisia.

Fiyatı Anomalileri
Authors: Fethi Şaban ÖZBEK
Abstract: Currently, some studies on food consumer price anomalies are being conducted in Turkey and other countries. However, the research on crop products producer price anomalies is limited. The purpose of this paper is to identify producer price anomalies for selected crop products in Turkey over the last ten years (2013-2022) using quarterly and annual Compound Growth Rates (CGR) of the monthly price level, which allows for price monitoring after accounting for the effects of seasonality and inflation on prices, making it an ideal way to use prices as the basis of an early warning indicator. According to the results, moderately or abnormally high prices were measured in all years except for 2015. Sunflower, sugar beet, potatoes and pistachio were the crop products abnormally high prices were measured more than one year in this period. Abnormally high prices were measured in the years of 2014 and 2021 at most. And, no abnormally high prices were measured in the years of 2015, 2017, 2018, 2019 and 2022. When the last three year situations of crop products with moderately or abnormally high producer prices were examined, wheat and maize were the crops with moderately high prices, and sunflower and sugar beet were the crops with abnormally high prices in 2020. In 2021, only the price of wheat was moderately high; cotton, maize, and barley were the crops with abnormally high prices. No abnormally high prices were measured in 2022, and the prices of wheat, cotton, tomatoes, maize, and potatoes were moderately high.

Spatıal Imagınatıon
Authors: Ayşenur AKBANA; Müge YURTCAN
Abstract: In addition to the role, they play in improving the quality of the environment, plants can be an imaginary factor in the perception of space and creating memory. Cupressus sempervirens var. pyramidalis which is considered in the context of this study can be easily distinguished from almost all the plants around it, both with its ecological and morphological features. In this study, the role of this plant in its use as a spatial image component has been revealed. It can define more than one image component in the landscape it is in, and it has the potential to strengthen the imageability feature of the component that it defines. Its use should be increased, especially in places where it is desired to emphasize the Mediterranean identity as an image component, by continuing its use from the past to the present.

Authors: Aşkın GALİÇ; Nurcan KARSLIOĞLU KARA
Abstract: In Türkiye, 98.5% of cattle in registered farms consist of dual purpose breeds. This also indicates how low the rate of use of beef cattle breeds in meat production is. However, feed efficiency, daily live weight gain and meat quality of beef cattle breeds are high and this is important in terms of farm economy and market quality. In this study, cattle breeds used for meat production in Türkiye and their performances were compared. According to the results, it was observed that the mean slaughter age of the breeds varied between 545.6±3.10 days and 619.1±3.03 days. Galloways came to the fore among all other breeds in terms of carcass weight and gain in carcass weight per day (P

- Analysis Of Climatic Properties In Terms Of Aronia Cultivation In The Case
Of Samsun
Authors: Yahya KADIOĞLU; Yusuf YILMAZ
Abstract: Aronia is a type of fruit that provides high income to producers in the regions where it is grown owing to its wide usage area and high marketing opportunities. Although it is stated in some sources that aronia cultivation started in Samsun in 2017, According to the official records of Samsun Provincial Directorate of Agriculture and Forestry In Samsun, aronia cultivation started in Gülyazı village of Çarşamba district in 2021. In 2022, the total size of aronia orchards reached 54.5 decares in 12 villages in Ilkadım, Bafra, Çarşamba Havza Kavak, Salıpazarı and Vezirköprü districts. As it is known, there is a strong relationship between plants and climatic conditions. Therefore, the adaptation of aronia cultivation to the climatic conditions in the region is an important issue. The adequacy of climate elements such as temperature, sunshine, precipitation, wind, relative humidity, frost, and snow in terms of aronia cultivation was investigated. For this purpose, the observations obtained from meteorological stations at different points of the area were compared with the climatic demands of aronia. The role of differences in plant development has been questioned and possible problems that may arise have been pointed out. Consequently, it has been concluded that the climatic features of the region are mostly suitable for aronia cultivation, but the extreme values during the vegetation period negatively affect the production.

- Analysis of the Current Situation of Wheat Cultivation in Bingol Province
Authors: Celal ARAL; Hasan KILIÇ, Ersin KARAKAYA
Abstract: This study was conducted with the aim of analyzing the current situation of wheat production companies in Bingol province, identifying the problems they face, and providing solution recommendations. The material of the research consists of " Proportional Sampling Method” " forms conducted face-to-face with 181 wheat producers identified through the "Relative Sampling Method" in Bingöl province and its districts in August-September and October 2021. It was determined that the average area allocated for wheat production in the visited farms was 30 decares. The declared wheat yield in the investigated farms, depending on the land size, was found to be an average of 278 kg/decare. As a result of the study, it was determined that wheat is predominantly grown in rain-dependent conditions using conventional methods, with 97.1% of the surveyed farms growing winter wheat and 2.9% growing spring wheat. Due to low nitrogen usage and consequently low protein content in the grain, the product has limited marketing opportunities. It was found that the average age of participating producers is 58.8 due to the migration of the young population to urban centers. Despite high precipitation in the province, the desired yield level cannot be achieved mainly due to soil structure, unresponsive producer profile to innovation, and other reasons. It is possible to increase the yield to higher levels by addressing the problems through researcher, publisher, and producer cooperation, focusing on improving soil structure and developing cultivation techniques. On the other hand, considering the small land size and low fertilizer and pesticide usage rate, the province can be evaluated as an opportunity for organic farming, which can lead to higher profitability for producers.

Hawthorn) Fruit Obtaıned from Genc District of Bingol
Authors: A. Şükrü BENGÜ; Halil İbrahim ERTEM, Mahire BAYRAMOĞLU AKKOYUN
Abstract: Crataegus orientalis grows in the Mediterranean region, Türkiye and Iran; It is a kind of fruit that may have yellow, red, orange colors. It is a fruit that is loved and consumed especially in our country and in Eastern Anatolia in autumn. Bingöl is a geography that consumes this fruit fondly with its districts and thinks that this hawthorn species is healing. Crataegus orientalis (Eastern hawtorn) used in our study was collected by us from Genç district of Bingöl in September 2021. As chemical analysis, some important element levels and some antioxidant tests were performed. Among the analyzed elements, sodium is 33512,50 ppb, magnesium is 432871,44 ppb, potassium is 2925823,19 ppb, calcium is 1623360,05 ppb, manganese is 1691,45 ppb, iron is 57778,99 ppb, cobalt is 117,62 ppb, copper is 1121,00 ppb and selenium is 6,61 ppb found. It has been observed that it has a very rich amount of element content. The antioxidant test results were observed as follows; total phenol content 79.76 ± 0.95 mg gallic acid g-1, total flavonoid content 43.04 ± 1.67 mg quercetin g-1, total antioxidant capacity 203.76 ± 12.28 mM ascorbic acid g-1, DPPH radical scavenging capacity 61.6 ± 0.57 % inhibition. Eastern hawthorn is a fruit that is beneficial for health with its rich element content and strong antioxidant values, as well as being a fibrous food. We think that understanding the value of this fruit, which is grown and consumed only in a limited time period of the year, such as a few weeks, will be beneficial for public health.

- Detection of Cucumismeloendornavirus Infection in South Marmara Region of
Turkey and Molecular Characterization of Isolates
Authors: Ali KARANFİL; Filiz RANDA ZELYÜT, Savaş KORKMAZ
Abstract: Cucumis melo endornavirus (CmEV) is one of the viral diseases that cause infection in cucurbits in recent years. The virus has been detected in a limited area in Turkey, and no study has been conducted on the causal agent's presence and genetic diversity in other production regions. This study was conducted in this context to find out the presence of CmEV infection in the Southern Marmara region, as well as their genetic diversity. Seventy-one samples showing virus and virus-like symptoms were collected from the cucurbit cultivation fields in the provinces forming the Southern Marmara region. Reverse transcription-polymerase chain reaction (RT-PCR) was used to analyze the samples using a gene-specific primer. The testing revealed that CmEV was present in 31 of the samples that were collected. Melon, zucchini, watermelon, cucumber, and gherkins are among the cucurbit species where the infection has been found. CmEV infection detected in cucumber and zucchini plants is a new host report for Turkey, and CmEV infection detected in watermelon plants is a new host report for the world. As a result of the molecular characterization of 6 isolates selected from among the isolates obtained, it was determined that the isolates generally showed sequence similarity of 91% and above at the nucleotide and amino acid levels. As a result of the phylogenetic analysis, it was seen that most of the Turkish isolates were in a different phylogenetic group from the world isolates. With this study, it was determined that the areas and cucurbit species in which CmEV detected increased in Turkey.

Authors: Malik ERGİN; Rabia ALBAYRAK DELİALİOĞLU, Yasin ALTAY, Özgür KOŞKAN
Abstract: This study presents a bibliometric analysis of lactation curve modeling in livestock based on 1455 articles from the WOS database spanning 1980 to 2023. It highlights the prominent researcher Macicotta NPP with 26 publications and identifies the University of Cornell as the leading institution in terms of publication count. The Journal of Dairy Science emerges as the most relevant journal in the field, with 393 papers. Among the countries represented, Turkey ranks 13th with 44 studies, primarily conducted in collaboration with other local authors. These findings offer valuable insights for future research endeavors in the domain of lactation curves and provide guidance on coauthor selection, journal selection, and relevant keywords. Therefore, it is suggested in this study that the lactation curve studies should be supported with different math models in livestock.

- The Relationship of Different Energy Sources and Economic Growth in
Environmental Perspective
Authors: Mustafa Latif EMEK
Abstract: The concepts of environment and environmental sensitivity, which started to make themselves felt after the second half of the twentieth century, have had a significant impact on almost every discipline, especially since the beginning of the twenty-first century. With the increase in industrialization, the negative impact of both industrial facilities and final industrial products on the environment has opened the concepts of economics and economic development to discussion in this context. The transition from fossil energy sources to nuclear energy and the use of renewable energy sources in production, carbon emissions and economic growth have become a multidisciplinary field of study, which are closely related to each other. In this study, in which data from the period between 1982 and 2020 are used, the long-term relationship between the amount of carbon emissions, per capita gross domestic product, nuclear energy and renewable energy was subjected to panel cointegration test and a long-term significant relationship between carbon emission and economic growth was examined. a relationship has been identified. On the other hand, no significant relationship was found between nuclear and renewable energy production and carbon emissions.

- Trabzon Chestnut Pollen: Physicochemical, Bioactive and Microbiological
Properties
Authors: Emine SÖNMEZ
Abstract: Bee pollen is an important bee product formed by mixing flower pollen collected by honeybees with nectar and bee secretions. Due to its rich content, it is accepted as a functional food today. In this study, the physicochemical (moisture, ash, pH), bioactive (total phenolic, flavonoid, antioxidant) and microbiological (total mesophilic aerobic bacteria, total yeast/mold) properties of chestnut pollen samples collected from three different regions of Trabzon Province (Of, Maçka, Esiroğlu) were investigated. As a result of physicochemical analyzes, the moisture content of the samples was between 7.95-8.93%, the ash content was between 2.95-3.23%, and the pH range was 5.30-5.33%. The highest protein content of 19.60% was obtained from Esiroğlu sample. The highest amount of total phenolic-flavonoid substance was detected in Esiroğlu sample, with values of 18.55 mg GAE/g and 11.23 mg QE/g, respectively. The antioxidant capacities of the samples were defined in the range of 74.86-83.43 µM Trolox E/g. It was concluded that the microbial load variability of the samples examined in terms of total mesophilic aerobic bacteria and yeast/mold counts in accordance with the quality criteria. Finally, it can be concluded that bee pollen, with its well-known healing potentials, could be used as a food additive in relevant products based on its attribute as a strong antioxidant and on its bioaccessibility.

- Research on Consumption of Sugar-Sweetened Drinks and 100% Fruit Juice
Authors: Faruk URAK
Abstract: Measurement of consumption of sugar-sweetened and 100% fruit juice drinks is typically patchy and often nutritionally focused, particularly in developing countries such as Turkey, with limited public perception and awareness of the health risks associated with excessive SSB consumption, and a low stimulus level of 100% fruit juice intake. In the study, the effects of socio-demographic, economic, and lifestyle characteristics of individuals and households on their different consumption probabilities of pure fruit juice (100% FJ) and sugar-sweetened beverages (SSB) were determined using the random-effects bivariate probit model in the context of family heterogeneity in Turkey. A richer source of information was elicited by deriving different probabilities from the bivariate random effects probit model. The applied model was found to be more compatible with the data and all the correlation coefficients examined were statistically significant. While most of the variables were statistically significant, according to the regressor effect, the probability of consuming 100% fruit juice among sugar-sweetened intakers was found to be greater or less than the probability of consuming 100% fruit juice of a randomly selected individual from the population (e.g., marginal probability). In this context, we can expect that the implementation of distinct intervention health programs that will involve different population segments will contribute greatly to the development of ideal outcomes. In addition, policy recommendations were presented considering the effects of very important variables.

- The Effect of Irrigation Waters at Different pHs on Some Trace Element
(Zn, Mn, Co, Cr, Ni ve Pb) Contents of Sorghum Plant Grown in Cd
Contaminated Soil
Authors: Hava Şeyma YILMAZ; Bedriye BİLİR, Erdal ÇAÇAN, Selim ÖZDEMİR, Eren İNAK, Faik BİNGÖL
Abstract: Environmental pollution is an important problem that is being tackled around the world and will continue to be increasingly struggled for many years to come. Among the most important links of the environmental pollution chain are agricultural pollution, heavy metals and Cd pollution. Today, sorghum plant has started to come into prominence in the use of contaminated areas in agriculture. Although many factors are effective in the absorption of elements from solution by plants, the most important one is soil pH. Soil pH affects the uptake of less or more trace elements by plants from the soil. The pH values of the soils are not easy to change in the short term. The aim of this study is to investigate the effect of irrigation of sorghum plant grown in soil contaminated with Cd (10 mg kg-1 Cd) with irrigation water of different pH on some trace element content of the plant. The study was established as a pot experiment, soil contamination was ensured and sorghum plants were irrigated with 5 different pH (pH: 5.0, 6.0, 7.0, 8.0, 9.0) water throughout the vegetation period (~120 days). After harvest, Zn, Mn, Co, Cr, Ni and Pb concentrations were measured in the roots, stems, leaves and cluster of the plant. Pb was not found to be statistically significant in the trace element concentration distribution among plant organs. Concentrations of other elements were found to be significant at the pstem>leaf>root, Mn: leaf>root>cluster=stem, Co: root>leaf>stem=cluster, Cr: root>leaf>cluster>stem and Ni: root>leaf=cluster> stem. With increasing pH levels of irrigation water, Zn, Mn and Pb concentrations generally decreased, Ni concentration decreased regularly in parallel with increasing pH, Cr concentration increased with increasing pH and Co concentration was statistically insignificant. As a result, the pH change in the irrigation water caused a change in the trace element uptake of the sorghum plant and the distribution of these elements among the plant organs.

- Revenue-Expenditure Analysis for Dual Use of Agricultural Lands: The Case
of AgriPV System in Türkiye
Authors: Bilge ŞENTÜRK
Abstract: Agricultural Photovoltaic Systems (Agri-PV), which combine energy production and agricultural cultivation, have become a significant research topic in many countries due to the benefits arising from the dual use of land. Agri-PV systems offer the opportunity for farmers to generate additional income by selling the electricity produced to the grid and significantly reduce irrigation expenses through self-consumption of the generated electricity. The primary data source for this study is the Agri-PV, which commenced operations as the first pilot project in Turkey in the Ayaş district of Ankara in 2023. This study, aiming to determine the fundamental costs and predict the income dynamics associated with Ayaş Agri-PV, holds a preliminary feasibility status regarding the economic performance of such systems in Türkiye. According to the analysis results, electricity price policies significantly impact the economic performance of Agri-PV systems. In addition to price policies prioritizing farmer welfare, suitable finance and business models, along with significant cost reductions in irrigation and increased income through the sale of electricity, can enhance the economic performance of Agri-PV systems.

- The Impact of Agricultural Loans on Growth in Turkey: A Panel Data
Analysis
Authors: Ferid ÖNDER
Abstract: Agriculture is generally classified as the general name of human activities carried out to obtain food, feed, textiles and most other products by raising plants and animals. The production of products from plant breeding, animal husbandry, aquaculture and forestry activities are seen as the basic components of agriculture. Moreover, it is a basic resource for meeting nutrition, clothing, shelter and energy needs. Agriculture is a sector of great importance, whose demand increases in parallel with population growth, and which meets the basic life needs of living beings, especially humans. The use of mass production methods becomes inevitable in agriculture for agricultural economic activities due to the limited land suitable for agriculture worldwide, the increase in productivity of technological production methods and cost structures. Therefore, the need for capital-intensive production methods in agriculture keeps the problem of financing agricultural production and the vital importance of agricultural credits on the agenda. In Turkey, the agricultural credits needed by the agricultural sector are provided by the private sector and banks, mainly by public sector loans. It is thought that solving financing problems will increase the level of agricultural production and affect economic activity positively. This study analyzes the relationship between agricultural credits and economic growth regionally in the case of Turkey using econometric methods. The results obtained by using new generation panel econometric methods show that there is a positive long-run relationship between agricultural credits and economic growth, although there are regional differences, but agricultural credits are not the cause of economic growth.

- Enerji Tüketimi ve Ekonomik Büyüme İlişkisinin Panel Ekonometrik
Analizi: Bric Ülkeleri Örneği
Authors: Ferid ÖNDER; Hüseyin AĞIR
Abstract: Various changes have occurred in many fields in countries during globalization. In the economic field, relationships between countries have developed, and the trade and investment environment has expanded. Industries have entered a highly developmental environment, competition has increased in some sectors, the global production and supply chain has changed, and production has become more integrated. International trade and investments have grown, communication has accelerated with technological development, and international cooperation has strengthened. While some countries have become economically stronger, others have become dependent on countries rich in natural resources. One of the most important areas of this dependence is energy dependence, which is experienced as a result of the increase in energy demand sensitive to production increase. This is because the increase in production is directly related to energy input. This study investigates the relationship between energy consumption and economic growth in BRIC countries, which exhibit similar characteristics in terms of various macroeconomic indicators. The results obtained from dynamic panel data methods using annual data for the period 1990-2020 reveal that a 1% increase in energy consumption across the panel in the countries included in the analysis increases economic growth by 1.46%. Therefore, energy constitutes one of the most important inputs for economic growth.
