Organic Hazelnut Farming Techniques: A Review النص الكامل
2023
Ali Turan
Growing environmental and human health awareness due to increased concerns caused by intensive agriculture, has resulted a trend toward organic farming. Organic farming first started in the mid-1980s worldwide, introduced in Türkiye during 1989–1999 with raisin, fig and apricot, and then hazelnut was included in these products. In our country, total of 21.418,57 tons of organic hazelnut production occurs on 12.129,24 ha in 18 provinces. Considering the entire hazelnut production area, organic production is quite low. Organic hazelnut production requires daily monitoring of mechanical control and cultivation measures in the orchard. In addition to this intensive labor, the extraordinary increase in agricultural inputs in the recent period may explain such a low production amount. However, given the recent environmental disasters in the world, human and environmental friendly production systems such as organic agriculture should be encouraged in order to restore the natural balance that has been significantly damaged.

The objective of this study is to diagnose the potato sector in the El Oued region by highlighting the technical and environmental situation of this sector. For this purpose, a field survey was carried out at the level of 75 farms in the El Oued region. The Oued Souf region’s Farm Sustainability Indicator (IDEA) is important. The assessment of agro-ecological, socio-territorial and economic indicators indicates that the agro-ecological indicator is the most represented by (the indicator of fertilizer and agricultural practices) by 98 out of 100. The results of this study show that this crop presents a good adaptation to the conditions of the region. This sector is undergoing significant development and is of great importance because this agricultural activity represents an economic potential at the local, regional and national levels. However, this sector remains fragile in relation to various constraints of a technical nature (unreasonable irrigation and fertilization and high seed prices), economic (price fluctuations and disorganized markets) and environmental (diseases, weeds) which directly influence the functioning of farms and therefore their profitability. This is why it is necessary to face the problems encountered and fight against the factors that can hinder the sustainability of this sector and give a competitive value.

Nalan Yazıcıoğlu
The objective of this research was to examine the impact of fenugreek gum and eggplant peel extract on multiple characteristics of rice pudding, encompassing parameters such as total soluble solids content, pH, color, syneresis index, storage stability, total phenolic content, antioxidant activity, flavonoid, and anthocyanin content, along with a sensory evaluation using a 5-point hedonic scale. Different concentrations of fenugreek gum (0%, 0.2%, 0.4%) and eggplant peel extract (0%, 0.25%, 0.5%) were prepared and incorporated into the rice pudding formulation at varying levels. Higher concentrations of fenugreek gum and eggplant peel extract in the pudding resulted in improved syneresis percentage (68.25±0.42%). This result shows reduced water release and improved storage stability. The addition of fenugreek gum also positively associated with increased storage stability, while eggplant peel extract had no significant effect. Furthermore, while the content of monomeric anthocyanins, total phenolics, total flavonoids, and antioxidant activity in the rice pudding samples increased with higher concentrations of eggplant peel extract, consumer acceptance scores were reported to be very low.

This study aimed to determine the structural relationship between internal and external egg quality (IEEQ) traits. In this study, 114 eggs produced from 24 weeks-old laying hens reared at the Ondokuz Mayis University Research Farm were used. Egg weight (EW), egg width (EWi), egg length (EL) and shell weight (SW) measurements were examined as external quality traits. Also, albumen height (AH), albumen width (AW), yolk height (YH), yolk weight (YW) and yolk diameter (YD) parameters were used as internal quality traits. Structural Equation Model (SEM) was used to determine the relationships between IEEQ traits. Data analysis was performed with the LISREL package. It has been determined that the variables that are important in determining the external egg quality are SW, EWi and EL. When the variables explaining the internal traits were examined, it was determined that the YW, YD, AW, AH and YH were significant. It was determined that the relationship between external egg quality and internal quality was 0.96 and external quality explained the internal quality by 91%. It has been determined that the SEM used in this study is sufficient to explain the relationship between internal and external quality.

Orhun Soydan
Our cities, most of which do not show planned development, are turning into ecosystems that threaten the living life of the natural and cultural environment as a result of many environmental problems such as increasing human and building density and incorrect land use. This negative situation has the opportunity to be resolved with urban planning in which the physical structure of the city is balanced and with landscape plans that will create open and green areas in the city that contribute positively to human and environmental health. The urban heat island effect, which has emerged as a result of intense urbanization in recent years, creates problems for city residents. Unfortunately, most cities in the world face this negative climate phenomenon. It becomes difficult to combat the heat island effect, especially in cities where construction density increases unconsciously. Ecological planning appears as a factor that will prevent these problems from turning into important environmental problems in the future. The most important component to be considered in ecological planning is climate. In this study, thermal comfort areas were tried to be determined along Dr Sami Yağız Street, which is one of the most frequently used areas of Niğde. Temperature and humidity measurements were taken at 25 points at equal intervals on both sides of the street. Measurements were made on different days of the week and at 4 different times during the day. The obtained values were transferred to ArcGIS 10.3 software and maps were produced. A universal linear extension system was used in the evaluation of climate data, and climate factors and bioclimatically suitable areas on the street were determined and evaluated in terms of comfort level. It has been determined that the humidity rate in the study area varies according to measurement hours, and there is no significant change in temperature.

In this study, the insecticidal effect of the Detech® (Turkish Diatomaceous earth) DE formulation against Galleria mellonella L. was determined. The study was conducted in a laboratory environment with materials taken from beehives produced at Muş Alparslan University in 2022. Diatomaceous earth (DE) was applied in two different forms (dust and slurry DE) and as positive control GüveSavar®, which is currently used against some pests in beekeeping. DE concentrations of 0, 3, 5, and 7 g/m2 in different exposure times were tested for the control of G. mellonella larvae. As a result of all treatments, the highest mortality occurred at 7 g/m2 dust DE concentration. Larvae (3rd stage) exposed to 7 g/m2 concentration according to dust DE mortality rates reached 100% mortality after 40 hours. According to the results of the slurry DE, the larvae exposed to the slurry diatom at all concentrations achieved 100% mortality at the end of the 96 hours. When the dust and slurry DE results were examined, the direct use of dust formulations greatly accelerated the effectiveness against larvae. The study showed very promising results, suggesting that slurry DE and dust formulations could be a new alternative control method for Greater Wax Moth. In addition, for the first time, the insecticidal efficacy of DE against the honey bee pest, the greater wax moth, was determined.
اظهر المزيد [+] اقل [-]Analysis of Monthly Precipitation at the Basin Scale in Türkiye النص الكامل
2023
Hasan Hüseyin Aksu
Basin-based water management strategy is one of the necessary instruments for the protection and sustainable use of water resources against climate change. In this paper, the monthly precipitation distributions of the 25 major basins in Türkiye were produced, and amounts and volumes were computed and analyzed. Only annual modeling and assessments of precipitation may hide months with precipitation shortages. Empirical Bayesian Kriging (EBK), Ordinary Kriging (OK), and Inverse Distance Weighting (IDW) were implemented in interpolation. EBK outperformed in all months and calculations were based on the EBK. The month with the highest precipitation potential in Türkiye is December (77.9 mm, 60.77 billion m3), and the month with the lowest precipitation potential is August (13.8 mm, 10.76 billion m3). In the basins, the monthly precipitation amounts range between 2.7 mm and 185.2 mm, and the volumes range between 0.02 billion m3 and 13.24 billion m3. The basins with the highest precipitation depth were determined as the East Black Sea, Antalya, Asi, and Ceyhan, and the lowest as the Small Menderes, Konya, and Tigris-Euphrates in different months. The monthly precipitation patterns and potentials of the basins vary widely. In May, June, July, August, and September, when water, particularly agricultural irrigation, is required the most, the 20 basins, except for the 5 located in Northern Türkiye precipitation shortage was determined.
اظهر المزيد [+] اقل [-]Determination of Production and Marketing Behaviors of Producers Selling Products to the Turkish Grain Board, (Kırşehir Province Mucur District Micro Field Study) النص الكامل
2023
Hasan Gökhan Doğan | Aybüke Bulut
The aim of this study is to examine the socio-economic characteristics of producers who sell wheat to the Turkish Grain Board (TGB), which is an interventionist organization in the purchase and sale of grain in Türkiye, as well as some of their behaviors regarding production, marketing preferences, and their relations with TGB. The sample of the study consisted of 100 wheat producers in the Mucur district of Kırşehir province. The obtained data were interpreted by converting them into tables, cross-tabulations, and graphs. The data in the cross tables were statistically interpreted using Chi-square analysis. It can be said that producers are not satisfied with TGBs’ purchasing practices for some reasons. The most important reason for this is that quality-based purchasing practices have an extremely negative impact on prices. It was determined that they were not satisfied, and this resulted in high price reductions in quality-based purchasing, and as a result, there was distrust in analysis practices. Quality-based purchasing policy is a method that allows wheat quality characteristics to be determined with various devices in a short time. This method, which is decisive in quality classification and product pricing scale, must be explained correctly to producers. Otherwise, the producer ’s trust in the TGB may gradually decrease. This can be achieved through initiatives taken by the institution or through various publications and training activities. One of the most important results of this study is that TGBs and decision-makers are more sensitive to local producers. For decision-makers to maintain their influence on the producer, they must carefully examine the details of the processes with an inductive approach, starting from the bottom up. This situation is considered critical in terms of food security.
