Tomato ringspot virus (ToRSV) belongs to the Nepovirus genus in the family Secoviridae. It has a wide host range and is listed as a quarantine virus in Turkey. In this study, 80 leaf samples were collected tomato, pepper, cucumber and grapevine cultivation sites located in three different parts of Hakkari province: Şemdinli and Cukurca districts and city center. Real-time TaqMan RT-PCR (Reverse Transcription-Polymerase Chain Reaction) method was used for the detection of the virus. Amplification was carried out in reaction mix including TaqMan probe, QuantiNova Probe RT-PCR kit (Qiagen, Germany) using primers based on 3’-UTR (untranslated region) of virus, which amplified a 182-bp product. ToRSV was detected in 13 of 80 samples and treshold cycle (CT) values ranged between 23.9–37.4. 16.25% of the samples collected from the districts were found to be infected with ToRSV whereas no ToRSV was detected in the samples collected from the city center. In Cukurca district, the virus was detected on pepper and cucumber samples and it was present on tomato, pepper, cucumber and grapevine samples in Şemdinli district. This study provides, to our knowledge, the first report of molecular detection of ToRSV by real-time TaqMan RT-PCR in Turkey.

Image analysis techniques are developing as applicable to the approaches of quantitative analysis, which is aimed to determine cultivar grains. Additionally, corn (Zea mays) grain processing companies evaluate the quality of kernels to determine the price of these cultivars. Because of this reason, in the study, a computer image analysis technique was applied on three corn cultivars. These were Zea mays L. indentata, Zea mays L. saccharata and a hybrid corn (Yellow sweet corn). These cultivars are commercially important as dry grains in Turkey. In the study, the grain color values were tested in the cultivars from Turkey’s collection. One hundred samples were used for each corn cultivar, and 300 corn grains in total were used for evaluations. Each of nine color parameters (Rmin, Rmean, Rmax, Gmin, Gmean, Gmax, Bmin, Bmean, Bmax) which were obtained from original RGB color channels with maximum and minimum values was evaluated from the digital images of three different corn cultivar grains. The values were analyzed with the help of the Multilayer Perceptron (MLP), Decision Tree (DT), Gradient Boost Decision Tree (GBDT) and Random Forest (RF) algorithms by using the Knime Analytics Platform. The majority voting method was applied to MLP and DT for prediction fusion. All algorithms were run with a 10-fold cross-validation method. The success of prediction accuracy was found as 99% for RF and GBDT, 97.66% for MLP, 96.66% DT and 97.40% for Majority Voting (MAVL). The MAVL method increased the accuracy of DT while decreasing the accuracy of MLP partly for the fusion of MLP and DT.

In this study, the development of imidacloprid and acetamiprid resistance in Myzus persicae populations and the relationship between neonicotinoid resistance and esterase enzyme were investigated in seven Myzus persicae populations which is collected from greenhouse pepper production areas in 2018. In order to determine the resistance ratios of aphid populations against the insecticides, 1 control and 6 doses were used. Each insecticide dose was used in 3 replicates and 25 adult female individuals were used in each replication. For imidacloprid, the highest and the lowest resistance ratios were found to be 6.88 and 3.19-fold, in K-4 and D populations, respectively. For acetamiprid, the highest and the lowest resistance ratios were found to be 7.35 and 2.72-fold, in K-1 and E-2 populations, respectively. Also, highest and lowest esterase activities were found to be 2.60 and 1.75 mOD min-1 mg-1 in K-4 and E-2 populations, respectively. According to the results of this study, imidacloprid and acetamiprid resistance determined in some Myzus persicae populations may be related to esterase enzyme. However, detailed studies are required to establish a clear relationship between resistance and enzyme.

Male and female mixed 200 pheasants were reared in intensive and outdoor conditions to assess the meat quality and some digestive tract traits. Color, pH, cooking loss, water holding capacity and drip loss were determined as meat quality traits. Production system did not have significant effect on most of meat quality traits. Conversely, most of these traits were affected by slaughter age. Water holding capacity significantly decreased but cooking loss increased by slaughter age. Total digestive system weight rate to body weight was decreased by slaughter age but did not differ between production systems. Small and large intestine lengths were significantly longer in indoor system and significantly decreased by slaughter age.

This study was conducted to determine the effects of the different intercropping design of maize/soybean compared with sole cropping, in combination with Vitormone (biofertilizer; Azotobacter) during 2012 and 2013. There were four different intercropping designs were used in the experiment: i) sole maize and soybean, ii) 1 maize + 1 soybean in alternate rows, iii) 1 maize + 2 soybeans in alternate rows and iv) 1 maize + 2 soybeans in intra rows under control with the Vitormone application. The experiment was laid out in a randomized complete block design with two factors and three replications. The results showed that the seed/grain yields and the Leaf area index of sole soybean and sole maize outperformed the intercropping. The highest yields for both maize (8.0 t ha-1) and soybean (3.26 t ha-1) and land equivalent ratio (1.26) were recorded at 1 maize + 2 soybeans in alternate rows among the intercropping. The effect of Vitormone was significantly positive for all cropping system except 1 maize + 1 soybean in alternate rows. This suggests that 1 maize + 2 soybeans in alternate rows can intercrop and combine with the Vitormone. The intercropping of cereal/legume has the potential to improve the utilization of resources in monocropped lands.
本试验旨在确定玉米/大豆不同间作设计与单作相比的效果，并结合使用维多酮(vitormonone)生物肥料;在2012年和2013年期间。试验采用4种不同的间作设计:1)单玉米+大豆，2)1玉米+ 1大豆，3)1玉米+ 2大豆，3)1玉米+ 2大豆，4)vitormonone控制下，1玉米+ 2大豆行内。试验采用双因素、3个重复的完全随机区组设计。结果表明，单作大豆和单作玉米的籽粒产量和叶面积指数优于间作。间作1玉米+ 2大豆交替行，玉米产量(8.0 t hm -1)和大豆产量(3.26 t hm -1)最高，土地当量比(1.26)最高。除1玉米+ 1大豆交替行外，维托莫酮对其他种植制度的影响均呈极显著正相关。说明1玉米+ 2大豆隔行间作可与vitormonone组合使用。谷物/豆类间作有可能提高单作土地的资源利用率。

Aphid species, their parasitoids and predators on vegetables (bean, cucumber, eggplant, melon, okra, pepper, pumpkin, tomato and watermelon) grown in Erzincan province, Turkey were determined. Surveys were carried out at weekly intervals from the seedling period until the end of the harvest period in Central and Uzumlu districts of Erzincan province in 2014-2016. 30-40 plants were randomly selected in the surveys and all parts of plants were investigated with a magnifier. Ten aphid, seventeen predator and seven parasitoids species were found. According to results, Lipaphis erysimi (Kaltenbach) (Hemiptera: Aphididae) was first recorded as a host of Aphelinus mali (Haldeman) (Aphelinidae: Aphelininae) in the world. In addition, parasitism rates of aphids were also established. The mean parasitism rate changed between 17.5% in 2015 and 4.39% in 2016. The relationship between parasitism rate, total parasitized aphid number and total aphid number were found. According to the analysis result, there was a very weak or a high positive correlation (r= 0.126-0.721) between total aphid number and total parasitized (mummified) aphid number, and not a correlation existed between parasitism rate and total aphid number as for years.

The principal aim of the present research was investigation of the effect of long-term sugarcane cultivation on some chemical and physical properties of soil in Karoun Agro-industry Unit in Shoushtar city, Iran. The study was conducted in a factorial arrangement based on randomized complete block design with two field factors at 8 levels and three depths in three replications. Soil samples were collected and some of their physical (e.g., bulk density) and chemical (e.g., pH, EC, soil available phosphorus, organic carbon, soluble sodium and available potassium) Features9 were measured. Results revealed that land use change and long-term sugarcane cultivation reduced electrical conductivity, the amount of soluble sodium and available potassium contents of soil in different depths, while caused increasing the percentage of organic matter and available soil phosphorous. However, at similar experimental conditions, no significant changes were observed in soil pH. The soil bulk density contents in farms under continuous cultivation of sugarcane, was more than the control field and HARZA. Moreover, soil exchangeable potassium was identified as a sensitive indicator of long-term sugarcane cultivation.

Landscapes, whose characters are the result of the action and interaction of natural and/or human factors, are dynamic. Proper understanding of today’s landscapes is only possible through the knowledge of their historical dimension, in other words, changes that have occurred in time-slices or time-depth. Historic Landscape Characterization (HLC) is an approach to the management and understanding the present historic environment as a product of past changes and as the basis for future change. HLC was applied to Kazdagi National Park which has very important ecosystems in terms of the future of Turkey especially Asia and Europe. In this research, Kazdagi National Park Historic Landscape Character Types were mapped and relevant attributes were assigned them in 127 years of time depth with ArcGIS 10.1 software. HLC which was completed on the computer has been confirmed by field study and ‘Direction of change’, ‘Rarity’, ‘Vulnerability’ analysis was carried out. Finally, the relevant assessments were made in order to contribute protection, management and planning of National Park.
