    Analysis of Change in Cost Factors in Canola Production: The Case of Çanakkale Province
    (2020) Semerci, Arif; Çelik, Ahmet Duran
    According to the data of 2018, Çanakkale City was 5th in Turkey’s total canola production with aproportional share of 7.50%. In this study, differences in input usage amounts and input costs wereanalysed according to the enterprise size. The data of the study were gathered from 83 canolaproducers who produced canola in 2018 in the Çanakkale Province by the Complete InventoryMethod. According to the research results, there was a statistical difference in pesticide cost at a 5%significance level between small- and large-scale enterprises. In terms of input usage per unit area,there was a statistical difference at a 5% significance level in machinery power usage according tothe enterprise size. Furthermore, there wasn’t any statistical difference in input usage betweenenterprise groups which indicates that large scale enterprises aren’t benefiting from the positiveaspects of the scale economy. Therefore, agricultural production in general and canola production inparticular should be supported with different tools and different methods in the medium and longterms.

    Hatay İlinde Pamuk Üretiminin Fonksiyonel Analizi
    (2018) Semerci, Arif; Çelik, Ahmet Duran
    Pamuk, kullanım alanı genişliği ve farklı sektörlerde sağlamış olduğu katma değer bakımından tarım ürünleri içinde özel bir yere ve öneme sahiptir. Dünya pamuk üretiminde Türkiye 8.sırada yer almaktadır. Hatay İli Türkiye’nin önemli pamuk üretim alanlarından birini oluşturmaktadır. TÜİK verilerine göre 2016 yılında Türkiye’de 4.160.098 da alanda; kütlü pamuk üretimi 2.100.000 ton, çiğit üretimi 1.260.000 ton, lif üretimi ise 756.000 ton olarak gerçekleşmiştir. Hatay İli Türkiye pamuk üretim alanlarında %11,54, kütlü pamuk, çiğit ve lif üretiminde %10,57’lik bir pay almıştır. Araştırmada elde edilen birincil veriler, Basit Tesadüfi Örnekleme Yöntemine göre %95 güven aralığı ve %5 ortalamadan sapma ile belirlenen 136 tarım işletmesinden elde edilmiştir. Elde edilen fonksiyonda üretim elastikiyeti katsayıları toplamı (??i) 0,976 olarak bulunmuştur. Bu durum ölçeğe azalan getiriyi göstermekle birlikte, elde edilen değer ölçeğe sabit getiriye oldukça yakındır. Fonksiyonda yer alan değişkenler içinde en yüksek marjinal etkinlik katsayıları 13,64 ile tohum (X1) ve 4,18 ile gübre girdisi (X2) olarak belirlenmiştir. Çalışmada Marjinal Teknik İkame Hadleri dikkate alındığında; enerji (X3) faktörüne göre arazi kira değeri (X7) faktörünün ekonomik optimuma en yakın düzeyde (0,98) kullanıldığı sonucuna varılmıştır.

    Input Usage and Difference Analysis in Cotton Production: A Case Study of Hatay Province– Turkey
    (2020) Çelik, Ahmet Duran; Semerci, Arif
    Cotton has an important place among other industrial products in the world and in Turkey in terms ofholding the largest production area, a high export value, and it being a crucial input in the food and animal feedindustries. Turkey is the 7th largest cotton producer in the world, and the region of Hatay where the researchtook place, has an 11.54% share in Turkey’s total cotton production area. It has a 10.57% share in unseededcotton, cottonseed, and in fiber production in Turkey. The primary data of the study were obtained from 136agricultural enterprises with a 95% confidence interval and a 5% average deviation. In the enterprises thatwere examined, 7,767 tons of cotton unseed were produced in a 14,674 da area in 2016. The average cottonproduction area size was found as 108 da and the share of cotton production in the crop pattern was found as38.20%. In the research area, in order to produce 529.29 kg/da of cotton unseed; 2.6 kg seed, 64.9 kg fertilizer,0.85 lt agricultural pesticide, 40.5 lt diesel fuel, 641.7 kw electricity, and 2.7 labor force (manpower) were used.According to analysis results; there was a statistically significant difference at a level of 5% between small andlarge enterprises in terms of fertilizer, labor force, and electricity usage levels. Despite that there wasn’t anysignificant difference between harvest method (by handpicking or machinery) and yield; this result indicatesthat the enterprises which harvest by machinery gain more income compared to the ones which harvest byhand. There wasn’t any significant difference in terms of irrigation method (surface irrigation or drip irrigation)but there was a statistical difference at a level of 5% in terms of income. In other words, the enterprises whichuse the surface irrigation method gain more income compared to the ones which use the drip irrigationmethod.

    Input usage and gross profit analysis in canola production: a case study of Canakkale Province, Turkey
    (Universidade Federal Rural de Pernambuco, 2021) Semerci, Arif; Çelik, Ahmet Duran
    Canola plant is grown worldwide for different purposes, and it ranks second after soybean among oleaginous seeds. Turkey is one of the countries in which its oleaginous oil supply amount dosen’t meet its own demand, therefore, Turkey’s canola production has been increasing in recent years as an alternative oleaginous seed product. According to the data of 2017, Turkey’s import value for oleaginous seeds and derivative products was 3,2 billion USD, in which 1,5 billion USD of it was oleaginous seeds. In other words, after petrol and petroleum products, oleaginous seeds and derivative products are placed on the top of Turkey’s importation product groups. One of the products that can fill Turkey’s oleaginous oil supply gap is the canola plant. According to the Turkish Statistical Institute (TSI) data of 2018, the proportional share of Çanakkale Province in Turkey’s canola production was 7.5%, making it the 5th region in canola production. The economic aspect of canola production was examined in this study and the data were obtained from 83 agricultural enterprises by means of the Complete Inventory Method. According to the research results, canola production took 1st place in the vegetative production pattern with 31.09%. The average canola production area was 8.41 ha, and average productivity was found as 2962 kg ha-1. In the study, the canola production gross output value was 1095.94 USD ha-1, the gross profit value was 293.60 USD ha-1, and the net profit value was found as 80.17 USD ha-1. It was also discovered that some subsidies for canola production such as field size based subsidies (diesel fuel and fertiliser subsidies) and deficiency payment subsidies; increased the gross output value by 27.31%, increased the gross profit value by 101.92%, and decreased production costs by 29.17%. In order to generate 2962 kg ha-1 of canola, (which is the production amount average per unit area) 4.5 kg of seed, 260 kg of pure fertiliser, 3,30 lt of agricultural pesticide, 130 lt of diesel fuel, and around 20 hours of man and machinery power were used. In order to increase the canola production amount in the Çanakkale Province it is necessary to; increase the level of irrigated production fields, increase certified seed usage, and revise the amount of deficiency payments according to the present conditions.

    Türkiye’de Süt Sığırcılığı Sektöründeki Gelişmelerin Analizi
    (2020) Semerci, Arif; Çelik, Ahmet Duran; Durmuş, Eylem
    Kırsal alanda faaliyet gösteren ve tarımla ilgilenen işletmelerin gelirini ve karlılığını artırmadahayvancılık sektörü özel bir öneme bir öneme sahiptir. Çünkü hayvansal üretim faaliyetleri tarımişletmelerinde; üretilen ürünlerin değerlendirilmesine, işgücünün dengeli bir şekilde kullanılmasına,işletmenin nakit ihtiyacının yıl içinde sürekli bir şekilde karşılanmasında ve riskin dağıtılmasınayardımcı olmaktadır. 2017 yılı FAO verilerine göre Türkiye, dünya sığır varlığının %0,99’u ve ineksütü üretiminde ise %2,78’lik bir kısmına sahiptir. TÜİK verilerine göre 2004-2018 döneminde sığırvarlığı yıllık %4,62 artışla 17.042.506 baş, inek sütü üretimi ise yıllık %7,23 ’lük artışla 20.036.877ton düzeyine ulaşmıştır. Belirtilen dönemde süt üretimindeki artışta kültür ırkı sığırların payı%33,63’ten %61,39 düzeyine yükselmiştir. Ancak dünya genelinde süt ineklerinin verim değerlerisıralandığında Türkiye 57.sırada yer aldığı görülmektedir. Türkiye’de süt ineği varlığının %21,74’ü,inek sütü üretiminin de %22,77’si Konya, İzmir, Erzurum, Balıkesir ve Diyarbakır illerindegerçekleşmiştir. Türkiye’de tarımsal üretimin artırılmasına yönelik olarak Tarım ve OrmanBakanlığı tarafından 2018 yılında verilen 14,5 milyar TL desteğin %25,79’u hayvancılık sektörüneaittir. Çalışmada elde edilen veriler süt sığırcılığına yönelik faaliyetlerin doğrudan ya da dolaylıolarak; bölgelerarası gelişmişlik farkının azaltılması ve kısal alanda faaliyet gösteren işletmeleringelirlerinin artırılmasında önemli bir sektör olduğunu ortaya koymuştur.
