The aim of this study was to compare the performance, egg quality and economic aspects of laying hybrids of different genotypes in free-range system. In the study, three different laying genotypes (Lohmann Brown, Lohmann Sandy and ATAK-S genotype) were used. Each group consisted of four replicates and each replicate contained 20 hens. Egg production, broken–cracked egg ratio, egg weight, feed consumption, feed efficiency, and viability were determined as performance traits. Eggshell strength, Haugh unit, yolk color, and shell color were determined as egg quality traits. The costs of eggs were assessed for economic analysis. The Lohmann Sandy genotype produced more eggs than the Lohmann Brown genotype (p < 0.05). The ATAK-S genotype reached 50% egg production age sooner than other genotypes (p < 0.05). The Lohmann Sandy and Lohmann Brown genotypes produced fewer broken eggs and heavier eggs compared to the ATAK-S genotype (p < 0.05). The ATAK-S genotype consumed more feed than the Lohmann Sandy and Lohmann Brown genotypes (p < 0.05). The Lohmann Sandy and Lohmann Brown genotypes have better feed efficiency compared to the ATAK-S genotype (p < 0.05). Eggs from the Lohmann Sandy genotype exhibit greater resistance to breakage compared to those from other genotypes (p < 0.05). The highest quality of albumen was identified in the eggs of the Lohmann Brown genotype (p < 0.05). The yolk color of Lohmann Brown genotype eggs is darker than those of other genotypes (p < 0.05). The shell color of Lohmann genotype eggs is a darker brown compared to eggs of other genotypes (p < 0.05). The cheapest egg cost was determined from eggs produced from the Lohmann Sandy genotype (p < 0.05). According to the results obtained from our study, it would be more appropriate to prefer the Lohmann Sandy genotype in the free-range system.

World trade in agricultural products, tends to increase. Turkey is among the countries in foreign trade advantages with its agricultural potential. As one of the most important tomato producer countries, monitoring of developments in the world tomatoes trade is extremely important for Turkey. The aim of this study was to evaluate Turkey’s position in world tomato trade. The developments of tomato foreign trade between Turkey and importer countries were analysed using Trade Intensity Analysis Method. Turkey supplied %75 of total tomato exports to Russia. Ukraine, Saudi Arabia, Iraq, Syria and Israel are important markets for tomato export. The epidemic (Covid-19 virus) has also been reflected in the international trade balances in tomato production. Giving importance to Turkey’s political relations and to boost its exports by providing market diversity, it is important for the sustainability of tomato exports. In this context, market researches should be conducted specially to find and entrance into new markets. Besides the fresh tomato, the activities for the export of tomato paste and canned tomato should be implemented.

Artan nüfus, tükenen doğal kaynaklar, küresel iklim değişikliği gibi nedenler, dünyanın mevcut tüketim düzeyinin artık sürdürülebilir olmadığını göstermektedir. Biyoekonomi; biyolojik kaynakları (tarım, gıda, ormancılık, balıkçılık, diğer biyo-temelli endüstriler) üreten, yöneten ve yayan her türlü endüstri ve ekonomik sektörü kapsamaktadır. Günümüz dünyasının tarım eksenli biyoekonomisi, sürdürülebilir kalkınma için yeni bir paradigma olarak değerlendirilebilir. Bu çalışma ile biyoekonomi kavramının ortaya çıkışı, dünyada öne çıkan biyoekonomi politikaları ve Türkiye’de bu alandaki gelişmelerin tarımsal açıdan değerlendirilmesi amaçlanmıştır. Birleşmiş Milletler Gıda ve Tarım Örgütü’nün raporuna göre, 2050 yılında insanların besin ihtiyacının yeteri kadar karşılanması için gıda gereksiniminin %70 artacağı, küresel su gereksiniminin %55 artacağı, dünya nüfusunun %40’ının su sorunu yaşayacağı vurgulanmaktadır. Tüm gelişmiş ülkeler bu tehlikenin farkında oldukları için biyoekonomi temelli politikalar ve kalkınma stratejileri üretmektedirler. Dünyada kırktan fazla ülke biyoekonomi stratejisini belirlemiştir. Türkiye’de de bu konuda atılan bazı adımlar vardır. Örneğin Tarımsal Araştırmalar ve Politikalar Genel Müdürlüğü bünyesinde bir yol haritası belirlenmiştir. Ancak henüz bir biyoekonomi stratejisi yoktur. Türkiye’nin de en kısa zamanda biyoekonomi stratejisini belirlemesi ve dünyadaki bu paradigma değişimine ayak uydurması gerekmektedir.

Prices of agricultural products fluctuate depending upon several factors. In Turkey, potatoes are one of the main products for which price fluctuations are observed. This study was undertaken to determine the effect of the fluctuation in potato prices on producer incomes in Turkey. The Neyman Method was used to determine the sample size. The number of enterprises required to achieve a representative sample size was determined to be 56, with a 5% error margin and a 95% reliability limit. The way in which the potato cultivation area is affected by price was examined. The Koyck model was utilized for this purpose. By using Koyck analysis, average lag time was calculated to be approximately 1 year. This result indicates that the fluctuation in potato prices has quite a rapid effect on production. It was determined that producer income varies greatly depending on annual potato prices. The difference between estimated potato price and the actual price for the year 2012 resulted in an income loss of 11,198.6 $/ha. Some sustainable efforts such as production planning can be recommended to prevent these price fluctuations.

In this study, development and alteration trends of ornamental plants sector in Turkey and the rest of the world were analysed. The competitive and structural analysis of outdoor ornamental plants sector in Konya province, Turkey, was carried out in accordance with the Strengths, Weakness, Opportunities, Threats (SWOT) analytical technique and Diamond Model of Porter. Main data of the study have been obtained by a survey method from 16 managers of enterprises. According to the results, the ornamental plants sector in Turkey developed vigorously, especially after 1980s, in parallel with other parts of the world. The cultivated area of ornamental plants in Turkey, which was 1513.2 ha in 2000, tripled to 4786.0 ha in 2011. Outdoor ornamental plants sector in Konya province has developed in parallel with that in the whole country and the number of enterprises producing has increased by 50% in the last decade. Competition level of outdoor ornamental plants sector is low in Konya. As a strategy to increase it, the aggregation of production in larger companies and diversification of the spectrum of plants more adapted to the natural conditions are discussed.
