Keskin, A., Ş. Keleş Formation of the Social Capital by Its Dimensions in Rural Areas of Erzurum Province in Turkey. The Journal of Animal & Plant Sciences, 28 (6) 2018 pp. 1854-1867 Abstract PDF
In this study, the formation of and the factors influencing social capital, the link between the rural lifestyle and the social capital were investigated. The levels of the social capital by their dimensions in rural areas were determined. The main material of the study is comprised of the cross sectional data, obtained from surveys conducted with random sampling method in 2016 from the counties and villages outside the Erzurum City Center. In the study, which utilized the Structural Equation Model, LISREL 8.72 software packages were used. The results of the study show that the elements that can be considered as the sources of social capital have become subjects that restrict social mobility and the cooperation instead of having a capitalistic value due to the fact that such elements are not supported by a sufficient and effective tradition of the society. The social capital, with its dimensions can only be realized in rural areas in a strong manner to the extent that the norms as well as ethnic and religion based strong social bonds play a unifying and infusive role instead of being a source of discrimination and marginalization in the society.

Keskin, A., Z. Kanat. Dünyada İklim Değişikliği Üzerine Yapılan Çalışmalar ve Türkiye\'de Mevcut Durum. Atatürk Üniversitesi Ziraat Fakültesi Dergisi, 49 (1) 2018 pp. 67-78 Abstract PDF
Bu çalışmada iklim değişikliği üzerine yapılan çalışmaların değerlendirmesi yapılmıştır. Bu değerlendirme iklim değişikliğinin hem genel etkilerini hem de tarım sektörü üzerine etkilerini içermektedir. Bu amaçla konu ile ilgili araştırmalar ele alınmış, izlenen süreç ve elde edilen sonuçlar karşılaştırmalı olarak değerlendirilmiştir. Sonuç olarak, bu araştırmalardan elde edilen bulgularda tutarsızlıklar olduğu ve bir görüş birliğine varılamadığı tespit edilmiştir. Ayrıca yapılan çalışmalarda doğru ve yeterli veri temininde de ciddi sıkıntılar yaşandığı belirlenmiştir. Daha güvenilir sonuçlar elde edebilmek için, çalışmalarda kullanılan modellerin çözünürlüklerini yükseltecek araştırmaların artırılması ve güvenilir veri tabanlarının oluşturulmasına yönelik çalışmaların yapılması gerekmektedir.

İkikat Tümer, E., A. Keskin, A. Birinci Factors Affecting the Farmers Attitudes toward buying Social Security Insurance: The Case of Erzurum, Turkey. Journal of Business Management, Vol. 5 (6) 2011 pp. 2129-2134 Abstract PDF
The aim of this study is to determine the factors which affect the attitudes of the farmers to buy social security insurance and to analyze them according to the kinds of social security policies. Binomial Probit Model was used for this purpose. According to the results of the study, farmers who deal with both animal husbandry and field crops are more inclined to make arrangement for social security scheme, compared with the farmers who deal with only field crops or only with animal husbandry. A negative relationship was found between the tendency to buy social security and forage crops production area and the income from animal husbandry. A positive relationship was found between the tendency to buy social security and nonagricultural monthly income, and the availability of tractors and cattle in the farm holding.

Tümer, E.İ., A. Keskin. A. Birinci Analysis of Factors Affecting Land Fragmentation in Erzurum Province, Turkey. Journal of Business Management, Vol. 4 (8) 2010 pp. 1614-1618 Abstract PDF
Fragmentation of agriculture prevents the efficient use of production factors. The aim of this study is to determine the factors which affect land fragmentation of farms in villages of Central District of Erzurum Province in 2004. Ordered logit model was used for this purpose. As a result of the study, it has been found that there is a positive relationship between tools and machinery assets which constitute the explanatory variable, the size of the enterprise, forage crop cultivation, population working in the agricultural sector and land fragments number. In addition, a negative relationship was found between arid land rental value and land fragmentation.

Keskin, A., E. İkikat Tümer, V. Dağdemir Demand for Inputs in Milk Production: The Case of Tokat Province. Journal of Business Management, Vol. 4 (6) 2010 pp. 1126-1130 Abstract PDF
The purpose of this study was to determine the gross margin and price, cross and morishima technical substitution elasticities for the cost inputs which play a key role in the milk produced in enterprises making animal insurance (Group I) and not making animal insurance (Group II), such as labour, feed, health and energy in Turhal district of Tokat province in Turkey. Model solutions were performed with Seemingly Unrelated Regression (SUR), using Translog production function. In enterprises Group I, own price elasticities of labour, feed, health and energy were estimated from the inputs demand model as -0.344, -0.247, -0.312 and -0.309, respectively. In enterprises Group II also own price elasticities of labour, feed, health and energy were estimated from the inputs demand model as -0.184, -0.197, -0.989 and -0.607, respectively. In addition, the gross margin calculated for the enterprises Group I was found to be more than three times as high as the ones calculated for the enterprises of Group II.

Keskin, A.., E. İkikat Tümer, A. Birinci Analysis of the Factors Affecting the Instrument and Machinery Assets in Enterprises that deal with Agricultural Production: The Case of Erzurum Province. Journal of Agricultural Research, Vol. 5 (8) 2010 pp. 600-605 Abstract PDF
The aim of this study was to determine the factors affecting the agricultural instrument, machinery and tractor assets of the enterprises in the central district villages of Erzurum province and the marginal effects of these factors. The Binomial Probit Model was used for this purpose. Education level of the farmers, their population, the size of the land, number of land parcels, disaster situation, crop cultivation and monthly income were found as factors affecting instrument and machinery possession. According to the study results, a unit increase in the education level of the farmers, their family population and in land assets they possess led to an increase of 17.85, 16.58 and 0.26% in their instrument and machinery possession possibility, respectively. Similarly, a unit increase in the number of land parcels, crop cultivation and monthly income led to an increase of 2.81, 38.58 and 0.04% in their instrument and machinery possession possibility, respectively. In addition, a unit increase in the education level of the farmers, land possession, the number of land parcels, crop cultivation and monthly income led to an increase of 19.55, 0.22, 15.39, 29.54 and 0.04% in the possibility of the enterprises to possess tractors.

Keskin, A. E. Kadanali, V. Dağdemir Demand for Inputs in Tomato and Cucumber: The Case of Uzundere. Journal of Agricultural Research, Vol. 5 (7) 2010 pp. 486-490 Abstract PDF
The aim of this study was to determine the gross margins of cucumbers and tomatos in greenhouses, price and cross elasticities and Morishima Technical Substitution Elasticity of the inputs such as labor, seedling, fertilizers and drugs, which play a key role in the production of these products in Uzundere District of Erzurum Province in Turkey. Model solutions, which were created by using Translog Cost Function were carried out by Seemingly Unrelated Regression (SUR). Price elasticity and cross elasticity of the inputs were calculated by using these model solutions. Similarly, Morishima Technical Substitution Elasticities of the inputs were obtained by the numerator equalities models. According to the study results, gross margins of cucumbers and tomatos per m2 were 5.000 TL and 3.303 TL, respectively. In addition, it was found that labor has the highest cost percentage within total cost.

Keskin, A.., V. Dağdemir, N. Demir Economical Analysis of Sheep Breeding According to the NUTS Level 1 Region in Turkey. Journal of Agricultural Research, Vol. 5 (7) 2010 pp. 641-645 Abstract PDF
The aim of this study was to provide an analysis of current situation in sheep breeding sub-sector of animal husbandry in the NUTS Level 1 region in Turkey. The total number of sheep and slaughtered sheep and the quantity of mutton production in Turkey have decreased by 42.31, 62.12 and 55.27%, respectively in 1983 - 2007 periods. While the mutton productivity has been above Turkey’s average in the East and Middle regions, they have been under Turkey’s average in the West, North and South regions. The analyses show that marketing margin for mutton changes between 20.82 - 15.91%. According to the result of the econometric analysis, the important factors in mutton production in the west and middle regions are mutton price; and beef price in the east region. On the other hand, the most important factor in mutton production in the middle region is technology. This situation needs to be assessed attentively.

Dağdemir, V., O. Demir, A. Keskin Estimation of Supply and Demand Models for Chicken Meat in Turkey. Journal of Applied Animal Research, 25 (2004) pp. 45-48 Abstract PDF
Chicken meat supply and demand models were estimated to determine the factors affecting the quantities supplied and demanded by using the time series data of 1983-1998 period, when Turkey’s economy was in transition to free market. According to supply and demand models that were estimated, it has been determined that producer price of beef and chicken meat affect chicken meat production. On the other hand, the population growth and consumer price for mutton affected the consumption of chicken meat. Supply elasticity was determined to be greater than that of demand. It is concluded that chicken meat producers are more responsive to the price changes than consumers.

Yavuz, F., O. Akbulut, A. Keskin, A Study on the Effectiveness of Breeding and Support Policies in Turkey’s Cattle Sector. Turkish Journal of Turkish Journal of Veterinary and Animal Sciences, 27 (2003) pp. 645-650 Abstract PDF
The proportion of Turkey’s cattle that were from high-gene cattle breeds and their crosses has increased from 0.8% to 60.7% over the last four decades. While the total number of cattle declined by 1.65 million head, total milk and meat production increased by 298% and 428% to 8.91 million and 359,000 tons, respectively. At the same time, milk per cow and meat per head increased by 184% and 144% to 1688 kg and 171 kg, respectively. According to a three-stage least-square regression analysis, milk per cow and meat per head, support policies since 1972 and milk and meat prices had a significant positive impact on total milk and meat production, while feed prices had a significant and negative impact on milk and meat production. An increase in the proportion of high-gene cattle breeds and cross-breeds significantly increased milk per cow and meat per head. In contrast, the import of high-gene cattle since 1986 has not significantly affected milk per cow or meat per head.
