Today, about 21% of the Turkey’s population lives engage plant production and animal husbandry; the most crucial aspect of livestock breeding is producing forage crops. Since 2000, growers in Turkey have been subsidized and encouraged to increase both their production and quality of forage crops. However, despite all this support and assistance, desired production levels have not yet been achieved. Therefore, it is equally crucial analyze the effects of factors other than the subsidies provided on forage crops production. This study aims to determine the socio-economic factors that affect sustainable forage crops production. The study was carried out in the province of Kayseri, specifically in 11 villages where both plant production and animal husbandry systems are common. The subjects of the study were selected through the Random Sampling Method and data was collected by surveying 310 forage crops growers. To identify dependency relationships between qualitative variables used mainly based on a statistical chi-square statistic. According to the analysis results, 35.5% of growers found forage crops production sustainable, whereas 64.5% of them thought that it was unsustainable. When both socio-economic variables and the answers to survey questions were taken into account, variables such as grower’s age, education level, income level, land for fodder crops, livestock count, recent increase in livestock count, subsidies, and the conditions under which sustainability may be maintained were found to be related to forage crops production sustainability.

Turkey’s poultry industry has experienced significant growth in recent years, resulting in the construction of many new production facilities. It is important to maintain optimum environmental conditions for a profitable production. In this study, temperature, relative humidity and air velocity distribution inside a broiler house were analysed. Computational Fluid Dynamics (CFD) simulations (numerical method) and direct measurements (experimental method) were used to determine the appropriate indoor environmental conditions. Simulated values were validated by comparison with the measured values using the normalised mean square error (NMSE). The measured and predicted parameters of temperature, relative humidity and air velocity at birds’ height, human height, and roof height upon comparison gave average NMSE values of 0.139, 0.181 and 0.090, respectively. The results showed a good agreement between simulated and measured values as obtained NMSE values were less than 0.25. In conclusion, CFD simulation can be used as an alternative method for the analysis of poultry house indoor environment. A better understanding of indoor environment conditions in poultry house provides useful information for manufacturers and end users for better management decisions.

The aim of this research was to determine the influence of drip fertigation on soil chemical properties and vertical distribution of nutrient in the root zone of three apple orchards planted on soils with different textures (loam, clay loam and sandy loam). The fertigation led to a significant decrease in soil pH, concentration of calcium carbonate (CaCO3) and organic carbon (C). Changes of these parameters were more pronounced in sandy loam soil than in loam and clay loam. Fine textured soils (loam and clay loam) had higher accumulation of available forms of P, K, Fe, Zn, Mn and Cu in the surface layer at 0-10 cm depth, compared to sandy loam soil. The results showed that, despite numerous advantages, drip system of fertigation can lead to negative changes of soil properties and that the sandy loam soils are more exposed, but in the same time more suitable for fertigation due to better vertical distribution of nutrients in a soil profile compared to loam and clay loam.

Cappadocia region of Anatolia hosts the third largest wild apricot population in Turkey. The objective of the study was to characterize 44 wild apricot genotypes selected from Cappadocia Region (Nevsehir-Turkey) as prominent with their late flowering, resistance to spring late frosts, large fruit sizes and/or late fruit ripening characteristics and 5 reference apricot cultivars (‘Hacihaliloglu’, ‘Kabaasi’, ‘Hasanbey’, ‘Aprikoz’ and ‘Levent’) with SSR (simple sequence repeats) markers. A total of 16 SSR primers were used and 13 of them were successfully amplified. Total number of alleles was 107, average number of alleles was 8.23; average He and Ho values were 0.722 and 0.669, respectively. Polymorphism information content (PIC) values varied between 0.471 and 0.845. There was a quite high genetic diversity among wild apricot genotypes that genetic similarity values varied between 12 and 96%. Homonymous and synonymous genotypes were not encountered.

House dust mites inhabit human houses, causing allergies and respiratory disease. Of them pyroglyphid mites produce at least 23 allergen groups, affecting millions of people worldwide. We determined the house dust mite fauna in the city of Ordu situated on the Black Sea coast of Turkey. Dust samples were taken from a total of 53 houses in 2013- 2015. The mite family Pyroglyphidae had the highest abundance in our samples, followed by family Chortoglyphidae. The most common species were Dermatophagoides pteronyssinus (Trouessart) and Dermatophagoides farinae Hughes (Astigmata: Pyroglyphidae). These two mite species are main allergen-producing species throughout the world, occurring in all sampled houses in the city of Ordu.

Barley scald is caused by the fungal pathogen Rhynchosporium commune. This disease causes substantial losses in barley production areas of the world. In this study, seedling resistance of 198 barley landraces, 104 wild barley (Hordeum spontaneum) genotypes and two susceptible Turkish cultivars (Bülbül 89 and Efes 3) to 6 R. commune isolates was assessed in greenhouse experiments. Virulence differences among the R. commune isolates were observed. One sixrowed barley landrace (Yeşilköy 9052) was resistant to all six isolates. Another six-rowed barley landrace (genotype no 17) showed resistant reaction to 5 isolates. Fourteen barley landraces were resistant and susceptible to 4 and 2 isolates, respectively. Twenty seven genotypes of H. spontaneum numbered as 5, 6, 7, 8, 9, 11, 16, 20, 30, 31, 36, 37, 48, 50, 51, 56, 58, 59, 60, 62, 67, 79, 80, 83, 90, 94 and 101 were found resistant to all six isolates of R. commune. Apart from these genotypes, 19 genotypes numbered as 1, 2, 32, 33, 34, 42, 43, 49, 52, 64, 66, 76, 77, 78, 96, 97, 102, 104 and 107 showed resistance to 5 isolates and susceptibility to only 1 isolate. Two susceptible Turkish cultivars Bülbül 89 and Efes 3 were found susceptible to 96% of the scald isolates. Resistant barley landraces and Hordeum spontaneum genotypes can be used as sources of resistance against R. commune.

Segmentation is an important part of each machine vision system that has a direct relationship with the final system accuracy and performance. Outdoors segmentation is often complex and difficult due to both changes in sunlight intensity and the different nature of background objects. However, in fruit-tree orchards, an automatic segmentation algorithm with high accuracy and speed is very desirable. For this reason, a multi-stage segmentation algorithm is applied for the segmentation of apple fruits with Red Delicious cultivar in orchard under natural light and background conditions. This algorithm comprises a combination of five segmentation stages, based on: 1- L*u*v* color space, 2- local range texture feature, 3- intensity transformation, 4- morphological operations, and 5- RGB color space. To properly train a segmentation algorithm, several videos were recorded under nine different light intensities in Iran- Kermanshah (longitude: 7.03E; latitude: 4.22N) with natural (real) conditions in terms of both light and background. The order of segmentation stage methods in multi-stage algorithm is very important since has a direct relationship with final segmentation accuracy. The best order of segmentation methods resulted to be: 1- color, 2- texture and 3- intensity transformation methods. Results show that the values of sensitivity, accuracy and specificity, in both classes, were higher than 97.5%, over the test set. We believe that those promising numbers imply that the proposed algorithm has a remarkable performance and could potentially be applied in real-world industrial case.
