2020
İbrahim Aydın | Betül Pak | Duygu Algan | Nuh Ocak
This study was carried out to investigate the floristic features (family, preference by grazers, growth form and response to grazing) and qualities of forage species collected from mountainous rangeland (Akdağ Mountain, Ladik) in the middle Black Sea region of Turkey. Forage samples were collected five times by 15-day intervals from the before-flowering stage to the after-flowering stage in 2015 and 2016. The total number of species was 105 species belonging to 73 genera and related to 26 families. Of the total species, 20 were from Poaceae (19.0%), 30 were from Poaceae (28.6%). Rests of the species belonged to other families (52.4%) dominated by families such as Asteraceae (13/55) and Lamiaceae (6/55), of which 26 species were weeds harmful to animals. While the percentages of decreaser, increaser and invader species were 16.2, 12.4 and 71.4, those of annual, biennial and perennial species were 31.9, 2.9 and 65.2, respectively. The number of species preferred by grazing was 74 (70.5%), while the number of non-preferable species was 31 (29.5%). The ME (MJ kg-1), RFQ and quality category of legumes, grass, and other botanical families were found as 8.88±0.07, 130.9±3.05 and very good, 8.00±0.07, 83.2±1.62 and good, and 8.98±0.07, 141.0±3.62 and premium, respectively. These results can be used as a management tool to improve rangeland quality and sustainability. The evidence from this study is that floristic pattern is not merely a result of invader forage species, but also might be a beneficial result that deserves further study for mountainous rangelands.

This study was conducted to identify the current problems of cereal crops like wheat and corn producers and to suggest solutions for overcoming those problems in Amik Plain (Antakya, Kirikhan, Kumlu, Reyhanli districts) in Hatay province of Turkey. In this study, the primary data was obtained by face-to-face survey from 100 cereal producers in Amik plain. All variables are given as frequency and percentage distribution, and numerical variables as mean. The survey assessed the level of education of grain producers, the number of individuals in the farm, record keeping, social security, crops (wheat and corn) growing area, yield, sowing and harvest date ranges, property and leasehold land use, cultural practices and grain production. The data were analysed using simple statistical analysis methods (frequency, averages, percentage distribution). The results indicated that about 50% of the cereal producers had higher educational degree. It was determined that producers had an average of 12.3 ha of wheat and 15 ha of corn cultivated area. Moreover, cereal production is well known as one of the cultural practices in the study area. The main problem of grain producers is that the low cereal prices. In addition, the Turkish Grain Board (TMO) does not purchase the production at the time of harvesting. Moreover, high production costs and corn irrigation are considered other problems that cereal producers are facing.

The present study was focused on the design and implementation of an experimental recognition system for dirty chicken eggshell by using an image analysis technique. Image analysis based observation and evaluation techniques can be used efficiently and effectively for agricultural product quality control. Dirt stains on eggs are the result of mainly by feces (black to light brown stains), uric acid (white stains), yolk, and blood. The experimental system was used to obtain dark level images of dirty stains of chicken eggs owing to feces. For this aim, the dirty chicken eggs which have dirty parts were put under a webcam, and dirtiness degree was evaluated by using developed image analysis software at the LabVIEW platform. For the experiment, 100 clean and 100 dirty eggs were used to accurate the determination of dark stains. The results of the research showed that the designed experimental system pointed an accuracy of 99.8% at painted grade eggs. On the other hand, the accuracy of the differentiation of the dirt stains by feces was 98.5%. The developed system can be upgraded for developing egg sorting machines by presence-absence of dirty stains in eggshell.

Orhun Soydan | Ahmet Benliay
After realizing that multi-storey buildings are contrary to human nature, the importance of natural landscape and green areas around it has been noticed. For this reason, people want to see how their environment will be in the design phase and the importance of project presentations is increasing day by day. Information technologies for spatial thinking, imagination and modelling have gradually started to be included in landscape design processes. The concept of virtual reality, augmented reality and immersive virtual reality are becoming more and more involved in our lives due to reasons such as the size of the devices getting smaller and their prices being relatively accessible to everyone. As an alternative to traditional presentation techniques and two-dimensional presentation techniques on the computer, making presentations in a virtual reality environment can be a stronger factor in people’s perception of the environment. In the study visual sets in basic, intermediate and advanced level of detail for the same landscape design and project site have been created. Each set consists of hand-drawn perspective image, computer aided perspective image, stereoscopic 360-degree VR image and an augmented reality model. In order to evaluate these visual sets, interviews were made with 10 landscape architects who are experts in the subject. As a result of the study, criteria’s for landscape presentations has been discussed and the advantages and disadvantages of landscape design presentations that will be created using virtual and augmented reality have been evaluated.

In this study, the effect of postharvest salicylic acid (2 mM), oxalic acid (5 mM), putrescine (2 mM) and calcium (4% CaCl2) applications on storage performance of Autumn Giant plum fruit were investigated. After applications, plum fruits were placed in modified atmosphere packaging (MAP) and stored for 40 days at 85-90% relative humidity conditions at 0.5±0.5°C. In order to determine the fruit quality characteristics after treatments, weight loss, soluble solids content, titratable acidity, fruit firmness, ascorbic acid, total flavonoids, total phenolics and total antioxidant content analysis were performed at 10 days’ intervals. According to the results, the effect of applications on weight loss was not significant. The maximum decrease in flesh firmness, titratable acid and ascorbic acid content during storage was determined in control fruits. Although fluctuations in the form of increase or decrease in biochemical compounds were generally observed, decreases occurred according to harvest value at the end of storage period. Considering all measurements and evaluations, it was determined that application of salicylic acid and putrescine had a more positive effect on preservation of fruit quality properties and biochemical content of Autumn Giant plum cultivar during storage than other applications.
