- Incidence and coat protein characterization of apple stem pitting virus
isolates from Isparta province of Turkey
Authors: Ali ÇELİK
Abstract: Turkey is one of the major countries in the world in terms of fruit growing due to its climate diversity and geographical features. Apple, which is one of these fruits, is grown intensively in Turkey, and especially the Mediterranean Region is important for apple agriculture. Today, viral diseases are considered as an important yield loss factor in apple farming. This study investigated the incidence and molecular characterization of apple stem pitting virus (ASPV) in Isparta province, a significant apple-producing region in Turkey. By using the DAS-ELISA and RT-PCR methods, ASPV infection was found in 7 out of 70 collected apple leaf samples. The partial nucleotid sequences of ASPV were obtained and registered in GenBank for accession numbers. The generated similarity matrix by using the representative isolates revealed that the new ASPV isolates shared 79–93% of their nucleotide sequences with GenBank reference acessions. The isolates collected in this research were clustered in group 1 of the phylogenetic tree that was created by selecting a specific number of isolates from GenBank and thought to be reliable in the phylogenetic differentiation of ASPV. This is the first study to examine the prevalence of ASPV in the Isparta region and its phylogeny. It is possible that the results of the research will contribute to a better understanding of the situation of ASPV in Turkey.

- The Effect of Different Nitrogen and Phosphorus Fertilizer Doses on the
Herbage Yield and Quality Properties of Atriplex nitens Schkuhr
Authors: Süleyman TEMEL; Cihan ŞAHİN
Abstract: There has been no previous study on fertilization on hay yield and quality values of Atriplex nitens Schkuhr. considered as an alternative feed source. With the present study, phosphorus (0, 5, 10, 15 kg da-1) and nitrogen (0, 5, 10, 15 kg da-1) fertilizer doses were applied in combination, and the effect of fertilizer doses on plant height, main stem thickness, number of branches, crude protein ratio, fresh herbage and dry herbage yield, acid detergent fibre (ADF), neutral detergent fibre (NDF), relative feed value (RFV) and crude protein yield was tried to be determined. For that purpose, a three-replication study was designed in randomized blocks according to factorial experiment design in the irrigated experimental field of Igdir University Agricultural Practice and Research Center in 2020. The analysis results showed that only phosphorus fertilizer doses and binary interaction (ADF and RFV) had a significant effect on the examined characteristics. In the results of studying, it was observed that as the dose of phosphorus fertilizer increased, the yield elements increased, whereas the quality values decreased. In the study, it was determined that the highest fresh hay (17379.6 kg da-1), dry hay (4899.3 kg da-1) and crude protein yields (427.15 kg da-1) were obtained from 15 kg P2O5 da-1 application. In terms of binary interaction, the lowest ADF content (38.87%) and the highest RFV (94.22) were obtained from N10P5 and N15P0 applications, respectively. As a consequence, it was determined that Atriplex nitens had no reaction to nitrogen fertilization, but its reaction to phosphorus fertilization was high.

- Determination and Evaluation of Noise Pollution in Layer Hen House: A
Bursa Case Study
Authors: Büşra YAYLI; İlker KILIÇ
Abstract: Both animals and employees need to improve the indoor conditions in livestock barns and keep them at an optimum level. With the development of automation systems for increased productivity and mechanisation, more systematic production occurs within the poultry houses and the need for a workforce is reduced. However, the increase in industrialisation and herd size can cause noise pollution problems in the poultry house. In this study, noise levels were measured and statistically evaluated in a laying hen farm operating in a battery-type cage in the Bursa region. It is aimed to be assessed according to environmental pollution and animal welfare. It was measured in the corridors between the rows of cages and on the cage floors with the studied facility's noise meter (EXTECH SDL600). The obtained noise data were determined by the SPSS statistical program, the variance analysis of the differences between the corridors and the relationship between the layer hen house environmental factors (temperature, humidity and wind speed) and the regression analysis. According to the results measured throughout the year in the investigated enterprise, the maximum noise intensity was measured as 80.6 dB, and the minimum noise intensity was measured as 76.3 dB. The differences between the noise values measured in the aisles and floors of the cage rows are statistically significant.

Abstract: The current study aimed to detect parasites in Hatay Mountain Gazelles (Gazella gazella), which are categorized as endangered according to the International Union for Conservation of Nature. The present study was conducted in Hatay Mountain Gazelle Wildlife Development Area, where 40 gazelles inhabited (30 ♀, 10 ♂), 15 of which were over three years old as well-considered adults. Fecal samples were taken from 60 fecal foci immediately after the defecation of the gazelles. Each of the fecal samples was analysed with Benedek sedimentation, Fülleborn flotation and Bearman-Wetzel methods and examined under a light microscope. In addition, Ixodid ticks were collected from an injured gazelle which was brought to Hatay Mustafa Kemal University, Wildlife Rescue and Rehabilitation Center, then were identified under the stereomicroscope. Nematodirus spp. (5/60, 8%), Marshallagia spp. (4/60, 7%), Trichostrongylus spp. (3/60, 5%) eggs, Dictiyocaulus filaria larvae (3/60, 5%) and Eimeria spp. oocysts (9/60, 15%) were determined based on the microscopic examination. Ixodid tick samples were identified as Rhipicephalus turanicus (2 ♀, 3 ♂). Thus this is the first report of the existence of parasites in Hatay Mountain Gazelles in Turkey. It is thought that skin and fecal examinations should be performed to prevent parasitic diseases in gazelles.

- Identification of Genetic Resistance to the Crown and Root Rot Caused by
Fusarium culmorum and Cereal Cyst Nematode (Heterodera filipjevi) in the
Turkish Cereal Varieties
Authors: Gül ERGİNBAŞ; Abdullah Taner KILINÇ, Salah LAASLİ EDDİNE, Fouad MOKRİNİ, Abdelfattah DABABAT
Abstract: Soilborne pathogens associated with cereals cause significant yield losses throughout the world. Among soilborne pathogens Heterodera filipjevi and Fusarium culmorum are two main destructive causal agents that attack the roots and crowns of cereals and have been reported as the most prevalent species in Türkiye. A total of 245 Turkish cereal varieties consisting of wheat, oat, triticale and rye which were registered between 1931 to 2013; were tested for their resistance to Fusarium culmorum and Heterodera filipjevi. The varieties were screened under controlled and/or field conditions for two successive growing seasons. The bread wheat ‘Murat-1’ was the most resistant variety for both pathogens. The durum wheats ‘Yelken 2000’ and ‘Yılmaz 98’ were found the most promising varieties for resistance to F. culmorum and H. filipjevi, respectively. The triticale ‘Umranhanim’ ranked moderately resistant at adult plant stage while ‘Presto’ and ‘Melez 2001’ were ranked moderately resistant at seedling stage for Fusarium culmorum. The findings of this study are important for the global wheat breeding programs as those genotypes are still being used in crosses for new genotype development.

- The Effects of Different Irrigation Managements on Some Soil Physical and
Chemical Properties in Hazelnut (Corylus avellana L.) Orchard
Authors: Edip Erhan KÜÇÜK; Mustafa SAĞLAM, Serkan İÇ
Abstract: This study was carried out in the Tekkeköy district of Samsun province to investigate the effects of different irrigation managements (control, 70% irrigation, 100% irrigation, 130% irrigation) on hazelnut orchard. After two years of irrigation management, disturbed and undisturbed soil samples were taken from two different soil depths (0-15 cm and 15-30 cm). Texture components (clay, silt, and sand content), field capacity (FC), permanent wilting point (PWP), pH, electrical conductivity (EC), and total nitrogen (NT) in disturbed soil samples and bulk density (BD) in undisturbed soil samples were determined. The values of available water content (AWC), macroporosity (MacP), and aeration capacity (HC) were calculated using the results of the analysis carried out concerning soil water retention in disturbed and undisturbed soil samples. As a result of the study, the effects of soil depths on permanent wilting point, available water content, bulk density, pH, electrical conductivity, and total nitrogen and of irrigation managements on silt content, sand content, field capacity, permanent wilting point, available water content, bulk density, aeration capacity, and pH were found to be statistically significant. While the effects of soil depth x irrigation management (D x SY) interaction on bulk density and pH were significant, the effect of any treatment on clay content and macroporosity was not significant. It has been determined that the bulk density of the hazelnut orchard soils, depending on the effects of soil depth and irrigation management, has increased at a level that the plant root development can be affected. Also, it was determined that 100% irrigation management had similar effects to the control treatment. While 100% irrigation management provided a higher aeration capacity in the plant root zone by creating less mechanical resistance to plant root growth, 130% irrigation management was the treatment in which the aeration capacity decreased the most.

- Isolation of Cold Tolerant Bacteria from Antalya Region and Analysis of
Their Growth Rates
Authors: Münevver AKSOY; İlker UZ, Raziye YILDIZ, Faik KANTAR
Abstract: Only a portion of chemical fertilizers applied to soil can be used by plants, because nutrients can become insoluble in soil. Application of biofertilizers can make the nutrients bio-available for plants. This practice would be beneficial for both plant productivity and the environment. Aim of this study was to isolate and compare growth rates of bacterial strains isolated from low altitude and high altitude regions of Antalya. Our results showed that, bacterial strains isolated from high alitudes have higher growth rates at room temperature (15-25 C) and temperatures as low as 2 C, compared to strains isolated from low altitudes. This suggests that strains that can grow at 2 C also would have higher enzymatic activities at low temperatures which makes them better candidates for development of biofertilizers. Using cold adapted biofertilizer would have a positive effect on plant productivity in agricultural areas located in cold regions of Türkiye. Therefore, isolation of these organisms and testing of their biofertilizer potential is important for our agricultural applications.
