Öğe Analysis of investment cost of apple cold storage facilities(Univ Fed Rural Pernambuco, Dept Letras Ciencias Humanas, 2015) Kart, M. Cagla Ormeci; Demircan, VecdiThe objective of this study is to make a comparison of normal and controlled atmosphere cold storage facilities in terms of investment costs and profitability in Isparta province, Turkey. The main material of the study consists of primary data gathered from the cold storage in Isparta province. The data covers 2011 storage period. The cold storages are analyzed in groups of normal atmosphere (51 facilities) and controlled atmosphere (8 facilities). According to the results of the study it has been determined that, the average capacity per facility in normal atmosphere cold storages is 4 978.43 tons and in controlled atmosphere cold storages 7 125 tons. The capacity utilization rate is found to be 86.72% in normal atmosphere storages and 96.49% in controlled atmosphere storages. In both types of storages, it has been determined that almost all of the stored products are apples. The net present worth of the investment is found to be $ 166 047.59 in normal atmosphere storages and $ 2 423 434.00 in controlled atmosphere storages. Internal rate of return is determined to be 6.63% in normal atmosphere cold storages and 12.36% in controlled atmosphere cold storages. When a comparison is made in terms of benefit-cost ratio it has been calculated to be 1.03 and 1.39 respectively for normal and controlled cold storages. According to the economical assessment criteria, it has been determined that controlled atmosphere cold storages are more advantageous than normal atmosphere cold storages.Öğe Economic analysis of agricultural chemical applications in vineyards production in Turkey: a case study of Isparta Province(Univ Fed Rural Pernambuco, Dept Letras Ciencias Humanas, 2015) Yilmaz, Hasan; Demircan, Vecdi; Kart, M. Cagla OrmeciThe main objective of this study was to determine the amounts and types of agricultural chemicals used in vineyards as one of the most important products of Turkey and to analysis the farm-level economic losses amount and cost of agricultural chemicals use in comparison with application levels used by growers and suggested in vineyards production by extension units and pesticide prospectus. Furthermore, growers' agricultural chemicals use practices were also determined. A survey was conducted using a face to face questionnaire with 68 vineyards producers from Central, Keciborlu, Yalvac and Senirkent districts of the Isparta province where there is intensive vineyards production. The farms were chosen by simple random sampling method. Chi-square test was used to analyze the relationship between the dosages of agricultural chemicals used by farmers and practices of agricultural chemicals use of growers and their socio-economic characteristics. In this study, it was also calculated that the cost of plant protection (pesticide and pesticide application costs) per hectare was determined as (sic) 404.77 having the portion of 47.16% of average production cost. Results of this research show that average usage of agricultural chemicals are 56 821.90 g per hectare as an active ingredient. The percentages of used agricultural chemicals are 83.13%, 14.29% and 2.58% sulphur, copper sulfate and pesticides, respectively. It was determined that use of pesticides in grape growing was 1 466.50 g ha(-1). The percentages of used pesticides are 66.53% and 33.47% fungicide and insecticide, respectively. In the research area, the excess use of pesticide was determined in the vineyards production. It was calculated that economic loss was (sic)47.82 per hectare due to overdose of agricultural chemicals. The percentages of this loss are 41.90%, 33.90% and 24.20% pesticides, copper sulfate and sulphur, respectively. It was calculated that economic loss was (sic)20.04 per hectare due to overdose of pesticides. The percentages of this loss are 52.87% and 47.13% insecticide and fungicide, respectively. Chi square test analysis showed that, there was a significant relationship between dosages of pesticides used by farmers and listening agriculture related program on radio, information needs in disease, insects and pests management, applying protective pesticides and experiencing health problems after exposed to pesticides.Öğe Economic analysis of agricultural chemical applications in vineyards production in Turkey: a case study of Isparta Province(Univ Fed Rural Pernambuco, Dept Letras Ciencias Humanas, 2015) Yilmaz, Hasan; Demircan, Vecdi; Kart, M.

Evrim; Polat, Mehmet; San, Bekir; Eraslan, Figen; Kart, Cagla Ormeci; Ozdamar, Damla; Yilmaz, Serife GuldenIn this study Antalya, Denizli, Isparta, Karaman, Konya and Nigde province' farms which are dominant in apple cultivation has been compared in terms of early warning adoption level and some social economic indicators. With this scope in the study region stratified sampling method had been used and sampling size has been determined 267 farms. In these regions early warning system has been used since the late 80's for black spot and codling moth. Especially after 2000's successful results of the system provide that a positive effect of the farmers' adoption level. According to the study results there is a high adoption level of farmers on apple cultivation from early warning system thus 41.6% of the farmers exactly adapt the pesticide application time from early warning system but farmers have lack of information about the system. There is a positive relation between adoption and education level, both levels increase at the same time. Early warning adoption levels also decrease unit production cost of apple. Relative profit has a statistically meaningful relation between early warning adoption level (p<0.05). Total pesticide cost increased 10.92% due to unnecessary usage. Many small farms in these regions can increase their income and provide market advantages with some amelioration in the early warning system, enlargement of practise areas.Öğe Economic Analysis of Integrated Pest Management Adoption in Apple Cultivation: a Turkish Case Study(Springer, 2017) Gul, Mevlut; Akpinar, Metin Goksel; Demircan, Vecdi; Yilmaz, Hasan; Bal, Tufan; Arici, S. Evrim; Polat, Mehmet; San, Bekir; Eraslan, Figen; Kart, M. Cagla Ormeci; Gurbuz, Damla; Yilmaz, Serife GuldenThis study aims to determine adoption level of farmers to integrated pest management (IPM) program and also to analyse the agricultural pesticide usage in apple growing. The primary data includes a research carried out through a questionnaire method which was conducted to apple producers in Antalya, Denizli, Isparta, Karaman, Konya and Nigde. According to the information received from the survey farms were separated into four groups according to IPM adoption level. It has been found out that the amount of pesticides used per hectare decreases according to the adoption of integrated pest management. While 1 kg apple cost found USD 0.40 in farms which does not follow IPM, USD 0.38 in farms which follow IPM. However, net profit per hectare is USD 556.75 in farms which does not follow integrated pest management; it is USD 482.51 in farms which follow high level IPM. In conclusion; to implement an efficient IPM, producers primarily should take cultural precautions and in the last resort they should look for chemical methods. They should avoid extreme use of nitrogenous fertilization, they should use high quality saplings, create a suitable ecological infrastructure and habitat management to conserve natural enemies of pests, select environment friendly pesticides, make descriptions of natural enemies of apple pests, give trainings about how to prevent pests contamination.Öğe ECONOMIC ANALYSIS OF PESTICIDE USE IN WHEAT PRODUCTION FOR SUSTAINABLE RURAL DEVELOPMENT(Latvia Univ Agriculture, 2016) Yilmaz, Hasan; Kart, M. Cagla Ormeci; Demircan, Vecdi; Auzina, AThe objective of this research is to do the economic analysis of pesticide application practices and level of pesticides used by the farmers in wheat production for sustainable rural development in Turkey. The primary data were collected from 84 wheat producers. Results of this research show that the average area of wheat production was 3.91 ha with 3 461.90 kg ha(-1). The average cost of wheat production was EUR 549.94 ha(-1). It was calculated that the average usage of pesticides was 1 10 3.50 g per hectare as an active ingredient in the wheat production. The average usages per hectare of active ingredient of insecticides, fungicides and herbicides were determined to be 48.00 g, 146.60 g and 908.90 g, respectively. Herbicides are the biggest pesticide group used in wheat production. They accounted for 82.37% of total weight of active ingredients, followed by fungicides (13.28 %) and insecticides (4.35 %). The study revealed that the farmers were using herbicides more than the recommended, fungicides and insecticides less than the recommended dosages. It was calculated that the average plant protection costs was EUR 50.25 ha(-1) which was 9.14 % of wheat production costs. The percentages of average plant protection costs were 85.0 3 %, 9.24 % and 5.73 % herbicides, insecticides and fungicides, respectively. The gain threshold was calculated to be 228.39 kg ha(-1). As a result, government should be promoting research into application technologies that mitigate risk and cost and maximize gain from pesticide used. Also, pest management and farmer training programmes in all crops should be developed to ensure sustainable food security, food safety, farmers' income, and rural development.Öğe Evaluation of Economic Structure of Cherry Growing in Turkey(Springer, 2020) Gul, Mevlut; Akpinar, M. Goksel; Demircan, Vecdi; Bal, Tufan; Yilmaz, Hasan; Arici, Serife Evrim; Acar, MusaCherry production has a vital role regarding income source for producers and export sources for Turkey. in Turkey, several studies have done regarding the technical practices, and most of them were not considered the economic dimension of cherry production. This research aimed to determine the production inputs, costs and profitability of cherry production. This study aims to reveal the relationship between orchard size and profitability by using general economic calculations based on Afyonkarahisar, Denizli, Isparta, Izmir, Konya and Manisa provinces, in Turkey. It is assumed that this study may be able to close the existing gap regarding other studies in the literature to a certain extent. This study support that more prominent cherry orchards had higher profits compared to smaller. the relative profit varies between 2.2 to 3.0 in the farm size groups. in this study, it was found that relative profit is the highest in the bigger-scale orchards. the most crucial problem for producers is to achieve a profitable cherry selling price. This study found the output/input ratio is high. Orchard size and production cost have a significant influence on the economic success of a cherry orchard. Production cost has a negative influence on profitability with a low cherry yield. in other words, cherry production is profitable in the research region, but some recommendations can be made within the framework of research findings to get better.Öğe How did post-2000 agricultural policy changes in Turkey affect farmers? - A focus group evaluation(Elsevier Sci Ltd, 2017) Ates, Hacer Celik; Yilmaz, Hasan; Demircan, Vecdi; Gul, Mevlut; Ozturk, Erdogan; Kart, Murside Cagla OrmeciThe aim of this study is to provide an analysis on how producers have been affected by the decisions made in 2000 in the agricultural sector. Data collected from the focus group discussions was compared to the agricultural policy effects on Antalya Burdur and Isparta provinces. The participants were primarily selected from a list of state institutions and organizations, and included representatives from cooperatives and producer organizations that are engaged in the agricultural sector and/or bring service to rural areas. The discussion revealed that small-scale farmers were unable to use the support provided by the policies; as a consequence, many of them were unable to cultivate their land and had to migrate. In general, the participants stated that significant social and economic changes did occur in rural areas, however they emphasized that these changes were to the detriment of small-scale farmers and instead favored fanners operating on large scale.Öğe TECHNICAL EFFICIENCY OF SHEEP FARMING IN TURKEY: A CASE STUDY OF ISPARTA PROVINCE(Univ Agricultural Sciences & Veterinary Medicine Bucharest, 2018) Dalgic, Ash; Demircan, Vecdi; Ormeci Kart, Murside CaglaThe purpose of the study was to analyze the technical efficiency of sheep farming using Data Envelopment Analysis (DEA) in Isparta province in Turkey. The data used were collected from 80 farmers using the stratified sampling method by means of a questionnaire. The technical efficiency of the sheep farming varied between 0.63 and 1.00. The mean efficiency of farms was calculated to be 0.41 and 0.48 for constant and variable returns to scale assumptions, respectively. The greatest slacks were defined as veterinary-drug costs and labour use. The most significant factors affecting efficiency of sheep farming were education, family and hired labour, A U, milk yield per sheep, age at separation (years) and number of lambs per sheep born (%).
