The Design of a Mini Plant Factory with Artificial Lighting and Application of Environmental Conditions Control System 全文
2019
Ali Çaylı | Emir Hüseyin Kaya
Due to rapidly increasing population and urbanization, agricultural lands are shrinking. However, environmental problems and pollution are constantly increasing. This poses a threat to agricultural production and food access. In order to overcome these threats, the use of fully controlled indoor production systems called plant factory is becoming widespread. The management of plant nutrition and monitor of environmental conditions is very important for production in the plant factory. Plant production is sensitive to environmental conditions. For this reason, it is necessary to make accurate measurements in order to ensure the correct climatic conditions. The high cost of control systems designed for this purpose is a problem for producers. In this study, a mini plant factory prototype and control system are presented which is developed by using open source hardware and software. In addition, the temperature, relative humidity and light measured by the low-cost sensors were compared with the reference devices and the system performance and stability were investigated.

The aim of this study was to determine students' consumption behavior based on their awareness of food safety. Data were collected using survey method. Study sample consisted of 400 students of Ünye Faculty of Economics and Administrative Sciences, Ordu University, Turkey. Chi-square test was used to determine whether participants’ levels of awareness of food safety differed by socio-economic characteristics. One-way analysis of variance (ANOVA) was used to determine differences in mean scores among awareness groups (low, medium and high) in terms of reading the nutrition information on food labels, food purchasing venues to be reliable and factors affecting food purchase decisions. Results showed that expiry date was the most important factor in food purchase decisions, followed by dates of production and packaging. Participants’ levels of awareness of food safety significantly differed by the proportion of monthly income allocated to food and their preference for cheap foods containing GMO. Supermarkets were ranked the most reliable venues for safe food purchasing, followed by groceries and greengrocers. Results also showed that food purchase decisions of the low and medium awareness groups were mostly affected by their families while those of the high awareness group were mostly affected by their doctors. Results indicate that firstly parents' awareness should be raised about food safety and safe food consumption so that future generations can be more conscious of these issues. In addition, courses on these matters should be included in curricula, and seminars or workshops should be held to raise students' awareness of food safety.

Duran Kılıç | Rüstem Cangi
This study was carried out in order to determine the effects of Mychorrizal Preparation (MP) applications on final take and root quality in grafted and potted grapevine sapling production. In this research, cuttings of five different Vine rootstocks (140 Ru, 110 R, 41 B, 1103 P and 5 BB) and scions of Narince grape cultivar were used. In addition, 5 commercials symbiotic mychorriza preparations (MP); Roots Deep Gel (RD), Endo Roots Soluble (ER), Myco Apply (MA), Bio-one (BO) and Biovam were applied. Scions were grafted on rootstocks by omega table grafting machine and then grafted cuttings were stored for three weeks at stratification room. The grafted cuttings were planted into polyethylene bags (12 × 20 cm size) containing 1:1 sterile perlite-peat mixture. Grafted cuttings were kept in greenhouse during 2 months for growing. After grapevine final take rates were determined, grapevine saplings were transferred to acclimatization environment. Root fresh and dry weights of grapevine saplings were detected in the first week of September. Research was designed according to completely randomized plot as three replications and as 50 grafted cuttings each plot. At the end of study, it was determined that both MP applications and rootstocks have a significant effect on final take and sapling quality. The ratios of first grade sapling varied from 21.5% to 93.3% in first year and from 10.3% to 79.3% in second year. Effects of MP applications on the total final take ratios differed depending on the rootstocks in both years. MP applications showed significant effect on total final take ratios of 110 R and 41 B in the first year, and total final take ratios of 5 BB, 41 B and 140 Ru in the second year. While the best results were obtained from MA, EN, RD applications in the first year, the highest final take ratios were in EN, RD and BO applications in the second year. The highest value on final take was obtained from 5BB rootstock, while the lowest value was recorded in 140 Ru rootstock. Effect of MP applications on the fresh and dry weight of root changed according to rootstocks.

Oktay Tomar | Gamze Yıldırım
Red beet (Beta vulgaris var. Cruenta Alef.) it is a flowering plant belonging to the family of Amaranthaceae and is cultivated in the regions extending from the west of Europe to all the Mediterranean coasts In Turkey; especially in the Aegean and Marmara regions. In the World, it is used in the production of milk and milk products, fruit juices, sauces, soups, confectionery, jelly, tomato paste, breakfast products, sausages and sausage products. In Turkey, in addition to these, it is widely used, in producing the turnip juice and pickles. There beet is particularly rich in minerals such as sodium, potassium, magnesium, calcium and phosphorus and also contains iron and selenium. Further; rich in antioxidant phenolic substances, betalain and flavonoid. In this study; antibacterial effect of extracts obtained from red beet outer shell and flesh inner part by using different solvents (ethanol, methanol and distilled water) on some food pathogens were determined by dise diffusion method. As a result of the research; the most antimicrobial effect was observed in the water extract obtained from the shell portion of red beet against Listeria monocytogenes with a 17 mm dilution diameter. This value was determined to be followed by methanol extract obtained from the interior of the red beet against Pseudomonas aeroginosa with a 16 mm dilution diameter. The lowest MIC and MBC values were on the Enterobacter aerogenes of beet peel methanol extract with values of 23.44and 31.25 μg / mL, respectively.

2019
Bulti Merga | Abdulatif Ahmed
Ethiopia’s agricultural production has been challenged by waterlogging, salinity, acidity, parasitic weed, and irrigation scheduling problems which has resulted in lower yields than the potential. Waterlogging is the main drainage problem in the small scale irrigation schemes in the Vertisols dominated highland areas while salinity and salinization is a common phenomenon in the large and medium scale irrigation schemes located in the lowlands of the country’s major river basins with predominantly salt affected soils. Soil acidity and associated low nutrient availability is one of the constraints to crop production on acid soils. Lime requirement for crops grown on acid soils is determined by the quality of liming material, status of soil fertility, crop species and varieties, crop management practices, and economic considerations. A considerable loss in growth and yield of many food and fodder crops is caused by root-parasitic flowering plants. Globally, Striga and Orobanche have a greater impact on human welfare than any other parasitic angiosperms because their hosts are subsistence crops in areas marginal for agriculture. In irrigated agriculture, efficient water management is an important element. Such practices can help bust sustainable production and maintain farm profitability in which there is limited water resource.
