This trial was realized in the greenhouses of Uludağ University Yenişehir Vocational School between 2009 and 2010 to investigate effects of water deficit on yield and quality parameters of onion during four crop growth stages. In this trial, fourteen irrigation treatments in four growth periods (establishment, vegetative, yield formation and ripening) of onion (Allium cepa L E.T Grano.502) were constituted and the yield and quality parameters found from these treatments were evaluated. The layout of the experiment was a completely randomized block design with three replications for each of the fourteen irrigation treatments tested. According to the content of the treatments, the irrigation amount water applied to the plants varied between 0 and 436 mm in the first year, and between 0 and 448 mm in the second year. Water consumption of onion in the first year ranged between 205 and 496 mm and in the second year ranged between 210 and 502 mm. Yield, bulb weight, diameter, height and dry matter ratio were determined statistically significant. In 2009 and 2010 years, the maximum yield were found as 52.2 t ha-1 and 52.4 t ha-1 in E100V100Y100R100 treatments, while the minimum yield were found as 0.8 t ha-1 and 0.5 t ha-1 in the E0V0Y0R0 treatments, respectively. Water- yield relationship factors (ky) in 2009 and 2010 years were found as 1.03 and 1.04, respectively. The maximum WUE and IWUE values were obtained from establishment and ripening periods. Establishment and ripening periods may be suggested as the maximum efficient irrigation periods for the onion applied with drip irrigation under unheated greenhouse conditions.

In recent years, environmental pollution, climate change and excessive use of natural resources have caused problems in the ecosystem. Honey bees are among the most affected by this environmental pollution. Climate change and environmental pollutants cause irregularities in colony development, the formation of weak colonies, the spread of diseases, the inability to return to the hive of field bees, and their mortality and low productivity. Turkey ranks second after China in the production of honey in the world. Honey is a strategic product for Turkey. This study investigated the effect of some environmental pollutants on honey yield in Turkey. This study used the time series analysis covers the years 1990-2017. In the research, honey yield as dependent variable, as independent variables; methane (CH4), carbon dioxide (CO2), diazot oxide (N2O) release, pesticide, insecticide, fungicide, herbicide use and industrial production index were used. After the stationary of the series was tested with ADF Unit Root test, the relationship between the variables was examined by Johansen Co-integration analysis. The effect of environmental pollutants on honey yield was tested by the FMOLS analysis method. According to the FMOLS results, the increase of 1% pesticide use, CH4, CO2, and N2O resulted in a decrease in honey yield of 0.36%, 0.70%, 0.74%, and 0.37% respectively. On the other hand, the increase of 1% insecticide, fungicide, herbicide use and industrial production index caused 0.15%, 0.14%, 0.09% and 0.84% increase in honey yield, respectively.

The aim of this study was to determine the effect of different doses and combinations of benzylaminopurine (BAP) and Putrescine elicitor on some plant characteristics of summer snowflake (Leucojum aestivum L.). The experiment was conducted for two years between 2017-2019 in the greenhouse of Uşak University, Faculty of Agriculture and Natural Sciences. Bulbs with ~7 cm circumference and ~9 g weight were used as a material of this study, and was constructed with randomized blocks design with 3 replications. The bulbs were treated for 24 hours before planting with 5, 10 and 15 mg/l BAP; 5, 10 and 15 mg/l Putrescine elicitor in different combinations (16 different combinations). Thereafter, all bulbs were planted in crates. In the first year, only plant height, number of leaves per bulb were recorded and at the end of the second year, the plant height, number of leaves per bulb, number of leaves per daughter bulb, number of bulbs, leaf weight, root length and weight, bulb weight, unit bulb weight, alkaloid contents were measured after removal of bulbs from the soil. According to the results, plant height ranged 19,3-30,0 cm; the number of leaves ranged 6.5 to 12.6, and the number of bulbs ranged 0.9 to 4.6. Root weight was determined between 13.4-47.1 g/parcel, fresh leaf weight ranged 12.4-49.2 g/parcel, and one bulb weight was between 3.5-14.6 g. It was determined that the bulb plant was influenced by different treatments. The maximum growth was noted with 5 mg/l Putrescine elicitor treatment that increased plant height, number of leaves per bulb each year and number of bulbs.

In this study, the effects of carvacrol addition which is a natural preservative to apple juice samples contaminated with Z. bailii which is an osmotolerant yeast and shows resistance against high sugar concentration, low acidity, ethanol content and pasteurization process, were investigated on some physicochemical and bioactive properties and also changes in yeast numbers during storage period. For this purpose, the response surface methodology was applied and storage time (1-41 days), storage temperature (4-20°C), sodium benzoate amount (0-0.1%) and carvacrol amount (0-750 ppm) were selected as processing variables. Significant changes in physicochemical properties were observed due to yeast viability occurred during the storage of apple juice samples. The increase in the amount of carvacrol caused a decrease in the number of yeasts about 7 log level and prevented the spoilage of fruit juices. However, the brix value of the samples without carvacrol showed a decrease of 50% as a result of yeast activity and the fruit juice could not be consumed. Total phenolic content of the sample was in the range of 136.7-645.7 mg GAE/L and the lowest total phenolic content was determined for the run 11 having no carvacrol while the highest total phenolic content was for the sample added with the highest carvacrol level. As a result of the optimization process, it was observed that the deterioration activities of Z. bailii could be prevented to a great extent by the addition of maximum amount of carvacrol.

Valuation of postharvest loss and identification of its causes enables to develop proper measures required to reduce losses. The study was conducted at “Fogera” District, South Gondar, Ethiopia between 2017 and 2018 years to assess the extent of postharvest loss of tomato (Solanum lycopersicum L.) and to identify major causes with respective handling system. In this study, a total of 125 farmers and 40 traders (10 wholesalers and 30 retailers) were involved as main respondents. Data collection was done using semi structured interview schedule, key informant interview, focus group discussion and observation. Besides respondents estimation, a sample analysis was conducted to estimate the extent of postharvest loss as per the FAO minimum quality standards. Descriptive statistics such as average, percentage, frequency and standard deviation were used to analyse data and tables, graphs and charts were used to present result. Result revealed that almost half of tomato produced is damaged and puts out of normal use with highest loss at producer level due to different causes which are complex and interrelated across tomato market chain. Marketing situation, insect pest and disease, lack of awareness, low economic status of producers, late harvesting, mechanical damage during harvesting and transportation, poor quality of produce and price fall were some of the reasons identified as major cause of post-harvest loss of tomato. For solving the postharvest loss problems, actors in supply chain has to develop cooperation and effective communication among all the research, extension, and industry personnel involved.
