Opis:
With the increasing need for energy, energy studies to be obtained from waste gain importance. In this study, it has been tried to determine the amount of biogas energy that can be obtained from olive pomace (pirina), which is produced by processing oil olives. Numerical maps of pirina amounts and potential biogas energy values and location maps of the proposed pirina processing plant were created. The necessary calculations were made by comparing the obtained results with the relevant literature information. In the study, the current potential biogas energy amount was calculated, maps were created and the electricity and gasoline energy equivalent levels of this energy were tried to be calculated using the 2015-2019 data of the Mediterranean, Aegean and Marmara Regions. The total potential amount of pirina in the research area is 1853375.7 tons and the potential biogas energy amount that can be obtained is 33360762.4 MJ. Pirina, which is the production waste after pressing the olives for oil, can be used for energy production. By using pirina to obtain biogas energy, both the utilization of pirina and the development of the regions will be provided.

Opis:
An ideal broiler house should be designed to minimize the effects of weather changes and to keep indoor conditions at the comfort temperature of the animals. In this case, this should be done with minimum cost and possible lowest operating costs. Degree-day methods are used in order to have knowledge of the energy need of any structure. With this method, the measured values or meteorological data can be used to give information about the heating and cooling energy quantities of structures. Depending on the climate change in recent years, the changes need to be examined that have taken place in order to provide optimum comfort in animal barn. Isparta province and districts were selected as the study area. The longterm average daily temperature values are used from meteorological stations of the selected region. The heating and cooling degree day values were calculated for selected balance temperatures in broiler breeding. Linear Regression Analysis and Spearman Rank Correlation Test were conducted to determine the changes of these values due to climate change. In conclusion, it was determined that there were statistically significant trends at 5% significance level in Egirdir (21°C), Isparta (31-29-25 and 23°C), Kasimlar (18°C), Senirkent (31-29-25-23 and 21°C), Sutculer (all selected balance temperature values) and Yalvac (31-29-25-23 and 21°C) in terms of heating degree-day values, and in Atabey (29-25-23-21 and 18°C), Barla (25-23 and 21°C), Isparta (23-21 and 18°C), Senirkent (29- 25-23-21 and 18°C), Sutculer (29-25-23-21 and 18°C), Sarkikaraagac (25-23-21 and 18°C), Uluborlu (25-23-21 and 18°C) and Yalvac (25-23-21 and 18°C) in terms of cooling degree-day values. As a result, it has been concluded that more energy consumption will be a concern for heating and cooling of the broiler house that will be built in the province of Isparta.

Opis:
Drought, water scarcity and climate changes are very important threats for agriculture on a global basis. Remote Sensing (RS) is accepted as a technique to collect data and determine water stress indices. Water Stress Indices (WSI) are useful tools to prevent drought and determine irrigation scheduling. The water stress indices are primarily identified as the Crop Water Stress Index (CWSI) and the Water Deficit Index (WDI). The effect of soil background is major problem to establish CWSI especially during early growth stage measurements of canopy temperature (Ts). Hence, WDI is a better index when it comprised with CWSI because of Ts. CWSI and WDI can be determined by two different techniques. These are determined by using measured by using traditional components to collect data and estimated methods by applying RS components to collect necessary data. Estimated method has many advantages when this method compared with measured method. However, estimated method needs some RS components which are infrared gun (IR), sling psychrometer, Spectro radiometer. With the help of these tools, the necessary data are obtained and WDI is determined. By using Spectro radiometer vegetation indices are defined. Among the many vegetation indices, the Normalized Difference Vegetation Index (NDVI) is mostly used one. By using NDVI determination of vegetation cover is easy and accurate technique to establish WDI. Establishing these both stress indices with less fieldwork and by saving money, time and labor conveys the necessary information for agriculturists using remotely sensed data especially for large agricultural fields.

Opis:
The goal of this study is to determine the crop water stress index (CWSI) and irrigation scheduling based on CWSI values, as well as to examine the correlations between CWSI, physiological parameters and grain yield of hybrid corn P31A34 in semi-arid climate conditions. In 2014 and 2015, the upper limit (UL) temperatures at which plants were entirely exposed to water stress were 1.178°C and 2.38°C, respectively. When the corn grain yield began to decline, the CWSI threshold value was 0.34, indicating the yield limit. Grain yield, crop water consumption, crop water stress index, chlorophyll content, water use efficiency and leaf area index were found to have negative correlations (p ≤ 0.01) with CWSI values in both years of the study. The findings revealed that in semi-arid climate conditions, a maximum of 30% water deficit could be used during the growing period of the corn compared to full irrigation (I100) for water savings and that a water deficit greater than 30% results in considerable grain yield losses. In areas with limited water resources, the moderate water deficit (I70) may be a viable alternative to the I100.

Opis:
This study was conducted to determine crop water stress index (CWSI) values and irrigation timing in the case of Derinkuyu dry bean (Phaseolus vulgaris L.). In 2017, dry beans were grown as the main crop according to the field design consisting of plots divided into randomised blocks. Irrigation treatment comprised full irrigation (I100) and irrigation issues with three different levels of water stress (I66, I33, I0). This study applied 602 mm of water under the I100 irrigation. The yield of Derinkuyu dry beans was equal to 3576.6 kg∙ha-1 in I100 irrigation. The lower limit (LL) value, which is not necessary for the determination of CWSI, was obtained as the canopy-air temperature difference (Tc - Ta) versus the air vapour pressure deficit (VPD). The upper limit (UL) value, at which the dry beans were wholly exposed to water stress, was obtained at a constant temperature. The threshold CWSI value at which the grain yield of dry beans started to decrease was determined as 0.33 from the measurements made with an infrared thermometer before irrigation in I66 irrigation treatment. As a result, it can be suggested that irrigation should be applied when the CWSI value is 0.33 in dry beans. Furthermore, the correlation analysis revealed a negative correlation between grain yield and crop water stress index and a positive correlation between yield and chlorophyll content. According to variance analysis, significant relationships were found between the analysed parameters at p ≤ 0.01 and p ≤ 0.05.

Opis:
Information on the energy needs of agricultural production activities carried out in any region can be obtained in advance. Many methods are used for this purpose. One of them is a degree-hour method. Kumluca district of Antalya province where pepper cultivation is done intensively was chosen as a study area. The growers prefer autumn production of pepper plants inside the greenhouses in this region. Production starts in early October and last until June. The long-term (1960-2015) thermometer temperatures in the study area were obtained from the Turkish State Meteorological Service. In this study, by using only meteorological data, during each growing season (planting, flowering, pollination, fruit ripening and harvesting) were obtained degree-hour values for the pepper plant and evaluated with Student-t test. Regression coefficients were obtained by correlating heating and cooling degree-hour values with different temperature values which are recommended during the vegetative growing season for the pepper plant. Regression analysis was performed between obtaining heating and cooling degree-hour values (dependent variable) and annual mean heating and cooling degree hour values (independent variable) which are suggested basic temperature values. In conclusion, the regression coefficients were determined as 0.99 for out of greenhouse heating degree-hour and as 0.90-0.99 for cooling degree-hour, respectively. Heating and cooling-hour values were found between 0.96-0.88 and 0.99-0.87, respectively. It was determined that there are very high correlations in the positive direction. According to different growing seasons of pepper, knowing how much less or more of heating and cooling degree-hour values is needed, one can give information in advance in terms of energy consumption or usage. Areas or regions where less energy is to be used can be determined in terms of agricultural production to be done in any region.

Opis:
As a result of the increase in the world population and the decrease in agricultural land, the need for food increases every day. Nowadays, breeding studies are carried out to increase the yield of plants to get more products from the same area. Furthermore, controlled production areas are created by optimizing climatic conditions and the continuity of production is ensured. It is called greenhouse, where production can be carried out throughout the year and the indoor temperature and humidity conditions can be controlled. Nowadays, greenhouses are now functioning as an industrial enterprise. However, greenhouses need to comply with the principles of quality production, efficient income growth and physical environmental protection. Almost all of the plant production in greenhouses in Turkey is done in the Mediterranean region, but in the Southeastern Anatolia Region, it is done in a very limited greenhouse area. The increase of protected agricultural areas in the Mediterranean region and the fact that the production volume cannot reach a certain limit makes it necessary to investigate alternative protected production areas. In this study, climate conditions of Antalya province and climate data of four provinces of the Lower Euphrates basin are compared with each other and statistically compared. As a result of, differences have been found between Antalya province and the provinces in the Lower Euphrates basin in terms of minimum, maximum, and average temperatures. However, there is no difference between the provinces in the basin except for Gaziantep in terms of climatic conditions. Therefore, it has been determined that Gaziantep province is not suitable for greenhouse cultivation. However, it has been concluded that if greenhouse cultivation is performed in this province, it is appropriate to perform cultivation in the areas where alternative energy sources can be used. It has been concluded that in the case that heating costs are reduced using alternative energy sources, Şanlıurfa and Kilis provinces are climatologically suitable for greenhouse cultivation and Adıyaman province is partially suitable for it.

The aim of this study is to determine the effects of insect net placed on ventilation openings in greenhouses on temperature, humidity and radiation energy from indoor conditions. In addition, the effects of insect net on the agents used in biological control have been tried to be determined. The study was carried out between November 2017 and May 2018 in Kumluca district of Antalya in 2 glass and 2 plastic greenhouses. Greenhouses; the glass greenhouse without insect net (GCG), the glass greenhouse with insect net (GNG), the plastic greenhouse without insect net (PCG), the plastic greenhouse with insect net (PNG) is named as. Temperature, humidity and solar radiation values were measured in greenhouses. According to the results of the research; It was determined that the recommended temperature values for pepper development are only suitable in January and well below the recommended values in February. In other production months, the average temperature values of with insect net greenhouses (PNG-GNG) used in ventilation openings were found to be higher than without insect net greenhouses (PCG-GCG). When the results of relative humidity values were examined, it was observed that the use of insect tulle in the greenhouses was lower than the control greenhouses. It was determined that the solar radiation values were lower than the control greenhouses (PCG-GCG) of the insect tulle greenhouses (PNGGNG) in other months except January and May. Therefore, we can say that the use of insect net reduces the amount of solar radiation. Accord ing to the results of temperature values; the growth of Orius Leavigatus and Amblyseius swirski, one of the biological agents and resistant to high temperatures, was observed to slow down in all other months except February. For Phytoseiulus persimilis (30°C and above), we can say that this is a suitable environment and that the eggs have emerged in a shorter time. The most suitable average temperature for the development of Aphidius colemani was reached only in January. In other months, the development of this agent slows down, parasitic insecticides can be said to decrease the rate of parasitoids. As a result; It was determined that the temperature values were higher in the greenhouses where insect net was used and the solar radiation values were lower than the control greenhouses. However, since the use of insect net causes the temperature in the greenhouse to increase, it may create a positive development for some bio agents. It is thought that producers using insect net should make production considering these negativities in temperature and solar radiation.

Opis:
The increasing world population renders the developed energy sources of the industry insufficient, and existing energy sources become expensive. It is anticipated that the energy deficit will further increase in the future. Scientists are in search of new energy sources in the face of this fact. It is considered that the cattle breeding potential of the Southeastern Anatolia Region may increase both as a result of state supports and arable lands. Determining the potential biogas energy production areas of the Southeastern Anatolia Region in terms of cattle breeding is possible with the use of today's knowledge and technology. With this study, it was aimed to determine the obtainable biogas energy fields and the current situation for the provinces in the Tigris Basin (Diyarbakir, Mardin, Siirt, Batman, Sirnak). The number of cattle in the basin for 2015 was benefited from in this framework. The boundaries of the research provinces were drawn using ARCMAP 10.0 software by making geographical corrections. In order for the inquiries of each province to be made independently from other provinces, all boundaries were divided on the basis of provinces, districts and villages as separate layers. These data constitute the main material of the study. The number of cattle was entered into the database of Geographical Information System (GIS), and the obtainable potential biogas energy production areas were determined considering the amount of waste that will be left in the environment by cattle. The finding that a total of 2809939 tons of annual wet manure can be obtained in the study area was obtained. It was determined that a total of 1175913 MJ biogas energy amount can be obtained per year from this wet manure. Further- more, the project created with a cartographic base, the geographical correction of which was made, was assessed in accordance with the purpose of this study in the database, and the areas that are suitable, non-suitable or partially suitable for biogas energy production areas were determined.

Opis:
In order to enhance the contribution of fig to the national economy and to raise farmers’ income level, it is necessary to encourage further cultivation of fig and direct farmers to fig production instead of alternative products. Most of the areas suitable for chestnut production are forestlands. There are orchards arranged with oak and chestnut trees with oak being predominant. Chestnut population in these areas should be increased. Cultivation area of this product that has many fields of use needs to be extended. Directing farmers to products that are storable in medium term with a broad market and high income is important both for the national economy and the farmers. The purpose of the present study is to remind producers the significance of two important products: fig and chestnut in the Kosk district of the Aydin province, Turkey, and to determine the areas suitable for growing these products within the study area. For this purpose the questioning and analysis features of GIS was employed. In this study, rainfall, temperature, soil texture, slope, elevation, wind direction, were taken into account to identify appropriate fields. As a result, approximately area of 13886 hectare of fig production and 3430.7 hectare of chestnut production were found as suitable area.

Ensuring the homogeneity of the indoor climate throughout the greenhouse is very important for uniform plant cultivation. In the study carried out to determine the indoor climate distribution in the heated greenhouse in the terrestrial climate, indoor temperature, relative humidity, dew point and vapour pressure deficit values were measured from 8 different measurement points. The distribution pattern of the measurement points was made horizontally and vertically at 2, 4 and 6 meters. Sensor placements are grouped vertically at 2 meters (G1: S1, S2 S3), at 4 meters (G2: S4, S5, S6) and at 6 meters (G3: S7, S8). Measurements taken during the day are divided into three parts. The climatic changes in the greenhouse were monitored as daily (00:00-23:30), daytime (08:30-17:30) and night (18:00-08:00) hours. According to the results obtained from the research, it was determined that the indoor climate parameters in the greenhouse change during the average daily, daytime and night hours at different times of the day and at different locations. According to this, it has been determined that it is important for better regulation of the greenhouse climate by monitoring the changes in the plant level as it rises from the greenhouse floor to the ridge with multiple sensors instead of a single sensor.

The clothing sector is one which possesses significance in global trade. The sector has been negatively affected by the pandemic due to its labor-intensive structure and possession of a relatively long and global supply chain. At this point, the Turkish clothing sector, which is the sixth biggest clothing supplier in the world, the third biggest clothing supplier in the European Union, and comprised 10% of Turkey’s general exports in 2019, should be investigated. In this context, this research aims to determine the effects of the COVID-19 pandemic on supply chain management in the Turkish clothing sector. Also, it aims to specify possible solutions against the negative effects of the COVID-19 pandemic. In accordance with the aim of the research, a survey was conducted in clothing enterprises. 391 survey questionnaires were incorporated into the research. According to the research results, it is determined that supply chain management in the Turkish clothing sector has been negatively affected by the COVID-19 pandemic. Order disruptions and cessations have ruined employment, production, procurement and investment processes resulting in financial disruptions. The most significant possible precautions that can be taken by enterprises that can be indicated as follows: benefiting from government support, heading towards online trade and an omni-channel strategy, actualising necessary alterations in product ranges, giving essential importance to innovation, efficient use of occupational health and safety systems, shortening the supply chain as far as possible, integrating digitalisation into all processes of the supply chain, and increasing the efficiency of marketing activities.

Opis:
Biological nitrogen fixation (BNF) is the process that provides organic nitrogenous compounds to the plants by using molecular nitrogen in atmosphere. Higher plants are not capable to use molecular nitrogen in atmosphere as a nitrogen source to generate essential proteins. Therefore plants either should be fertilized by adequate nitrogenous fertilizers or the microorganisms which are capable to produce nitrogenase should provide nitrogen to the plants by BNF. From among a number of factors affecting BNF, soil moisture content and ambient temperatures are considerably effective on the fixation rate. Therefore the global warming would be dramatically defective on BNF, thus effects of soil moisture as well as soil and ambient temperatures on BNF should evaluate prior rising temperature. A pot experiment was carried out to determine the effects of soil water contents on BNF. Four different soil water contents (%25, %50, %75 and %100 of water holding capacity) were adjusted either every 3 days or just after plants indicate wilting point. Non-inoculated pots were added to experiment as a control. The results revealed that BNF is affected by different level of soil water content. The mechanism of this effect would not be the direct effect of water, but the side effect of water on soil oxygen content; therefore, an aeration capability.

Opis:
This thesis was carried out in four greenhouses with arc roofs with a base area of 6 m2 and a side height of 2 m in the experimental area of Isparta University of Applied Sciences, Agricultural Research and Application Center. For this purpose, greenhouse with LED lighting (LED), Red-colored (RG) greenhouse, Blue-colored greenhouse (BG) and greenhouses with transparent covering material (TrG) were used as materials. The study was conducted between February and May 2019. In this study, the effects of different color cover material on the development parameters of radish were determined by measuring the temperature, humidity and solar energy values of the greenhouse. In order to do these measurements, sensors are placed in the greenhouses. Solar energy measurements were taken between 10:00-16:00 hours considering sunshine time. Temperature and humidity measurements were recorded for 24 hours. When the values obtained from TrG, BG, RG and LED greenhouses were examined, it was determined that the highest temperature value of the radish plant in the LED greenhouse during the growing period. Average greenhouse indoor temperature values were found to be between 13°C and 16°C in LED greenhouse, between 6.5°C and 15o C in COG, between 6o C and 14o C in BG and between 6.5°C and 12.2°C in RG. Solar energy values are between 26 and 1053 Wm-2 in LED greenhouse, 21.1 and 856.6 Wm-2 in TrG, 17.9-680.3 Wm-2 in BG and 14.3-633.1 Wm-2 in RG has been determined. In order to examine the growth parameters of radish plant, root weight, height, stem length, length of green parts and root diameter were examined. Root weight was higher in LED greenhouse, plant root length and length of green parts were higher in RG, plant root diameter and weight of green parts were higher in TrG. As a result, it was concluded that the development of radish plant is the worst in the BG in terms of both temperature and radiation energy values. In particular, it was determined that the radish plant in BG appears to be different from the other greenhouse plants. When the development of radish is taken into consideration in four greenhouses, it is concluded that TrG can be recommended for plant root weight, root diameter and green component weight and RG can be recommended for height and stem length. When the developments in the BG were considered, it was concluded that the application of blue color is not suitable for the cultivation of radish.
