COMPARISON OF THE HEATING ENERGY REQUIREMENTS OF THE GREENHOUSES IN THE TIGRIS BASIN WITH ANTALYA
(Univ Agricultural Sciences & Veterinary Medicine Bucharest, 2017) Saltuk, Burak; Mikail, Nazire; Atilgan, Atilgan; Aydin, Yusuf
The rapid growth of the world population also increases the amount of food needed for the human being's life. Therefore, applications that increase productivity and through which production can be made throughout the year in plant production come to the forefront in the world. In this context, one of the most important activities is greenhouse cultivation through which production can be made throughout the year by keeping climate conditions under control. Greenhouses are climate-controlled plant production structures in which indoor environment conditions can be controlled and can be kept in accordance with growing conditions. Heating must be performed during the winter period in greenhouses if it is desired to make production throughout the year. In Turkey, almost all of greenhouse production is performed in the Mediterranean region, and the production areas are situated in a relatively limited area in the Southeastern Anatolia Region. In this study, 10-year climate data (Maximum, Minimum and Average Temperature, Humidity, Sunshine Duration and Amounts) of 5 provinces (Diyarbakir, Mardin, Siirt, Batman and Sirnak) in the Tigris basin were achieved by considering the climatic conditions and production capacity of Antalya province, which has the most production areas in Turkey. According to the results obtained, the average minimum temperature for each month showed a statistically significant difference according to the provinces (p<0.01). Consequently, while the highest heating load was 1852.836 W/m(2) for a greenhouse of 576 m(2) for Antalya province in January during which heating requirement is the maximum, 3887.13 W/m(2) and 5615 W/m(2) heating load differences were obtained from Mardin and Diyarbakir provinces, respectively.
CURRENT SITUATION IN MEDITERRANEAN GREENHOUSES AND A STRUCTURAL ANALYSIS EXAMPLE (MERSIN PROVINCE)
(Fresenius Environmental Bulletin, 2018-12-12) Saltuk, Burak
Greenhouse cultivation is one of the most important income generating branches of agriculture. Nowadays, computer softwares are used for anything as it is being used for planning greenhouses, more robust construction and economical results are obtained this way. Business owners, who investing their money in greenhouses, are copying the structural features of existing greenhouses with all wrong calculated parameters and errors. Leaving their valuable cash and future of their investment in the hands of an iron-smith. As a result, the greenhouses which are built without static and strength calculations, more materials are used, or insecure constructions are being applied. When an economic loss occurs depending on structural damage it will unavoidably lead to economic losses for farmers and implicitly for the country. This study, contains emphasises on the structural analyses of a two-span gothic roofed plastic covered greenhouse, having an area of 900 m2 located in Mersin province. Structural analysis of the greenhouse was made with SAP2000 program. Mechanical properties of steel used in gothic roofs, plastic covered greenhouse's, theoretical load calculations are made depending on the TS 498 and TS EN 13031-1 Turkish standards.Variable loads on the greenhouse are calculated as distributed loads with classical methods by analyzing the gothic roofed plastic covered greenhouse according to load combinations (wind, plant, fixed) with SAP2000 program.
Defining Irrigation Scheduling Based on Crop Water Stress Index and Physiological Parameters for Hybrid Corn in Semi-Arid Climate
(Middle Pomeranian Sci Soc Env Prot, 2022) Ucak, Ali Beyhan; Saltuk, Burak; Rolbiecki, Roman; Atilgan, Atilgan
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 & DEG;C and 2.38 & DEG;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 & LE; 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.
Derinkuyu dry bean irrigation planning in semi-arid climate by utilising crop water stress index values
(Polish Academy of Sciences Publishing House, 2023) Uçak, Ali B.; Atılgan, Atılgan; Korytowski, Mariusz; Koci?cka, Joanna; Liberacki, Daniel; Stachowski, Piotr; Saltuk, Burak
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. © 2023. The Authors.

DETERMINATION OF HEATING AND COOLING DEGREE-DAY VALUES AND HEATING AND COOLING-DAYS IN BROILER HUSBANDRY: CENTRAL ANATOLIAN CASE
(Latvia Univ Agriculture, Faculty Engineering, Inst Mechanics, 2018) Atilgan, Atilgan; Yucel, Ali; Saltuk, Burak
The general aim of barns is to create suitable environments for animals against adverse weather conditions. Barns should be designed in such a way as to minimize the effect of weather changes and keep indoor conditions at the values of animals' desire. It is observed that the energy costs of unsuitable barns are high and the efficiency is not at the expected levels. Degree-day methods can be used to obtain information about the energy needs of any building. With this method, measurement values or meteorological data can be informed about the heating and cooling energy quantities of buildings. However, depending on the climate change in recent years, the climate changes that have taken place in order to provide optimum comfort in the barns should be examined. For this purpose, the Central Anatolia Region covering 13 provinces of Turkey was chosen as a studying area. The annual average daily temperature values of 13 meteorological stations in the region were used. For a broiler house, heating and cooling degree-day values and day numbers were calculated according to the based temperature values. Relationships between heating degree-day values, cooling degree-day values and degree-day numbers calculated according to the based temperature values were investigated by the linear regression analysis. As a result, it was determined upon an evaluation of the calculated heating degree-day, heating degree-day number, cooling degree-day and cooling degree-day number values that the cities of Aksaray, Ankara, Karaman, Kirikkale and Konya are most suited for broiler breeding.
Determination of some environmental energy requirements in broiler poultry housing
(Parlar Scientific Publications, 2020) Saltuk, Burak; Yucel, Ali; Atilgan, Atilgan
In the study, the long-term temperature data of the meteorological stations belonging to eight provinces in the Mediterranean Region were used as material. These values of Meteorological Stations cover the years 1950 and 2018. By using the long-term maximum and minimum daily temperature values used in the study, heating and cooling Degree-Day (HDD and CDD) and heating and cooling Degree-Day Numbers (HDDNs and CDDNs) of each province were calculated. These values were determined by considering the recommended base temperature values for broilers. In addition, energy requirements, amount of fuel and cost values were calculated by using HDD and CDD values. The most suitable broiler breeding areas were determined by considering the calculated energy requirement, fuel and cost amounts as well as HDD and CDD values. Therefore, it has been concluded that the most suitable cultivation areas are Mersin and Adana regions. In addition, natural gas, which is an environmentally friendly and clean fuel, was found to be most suitable in terms of heating costs. Also, general equation has been developed to be used in the estimation of HDD, CDD, HDDN and CDDN values for broiler breeding to be established in the research area. © 2020 Parlar Scientific Publications.

One of the agricultural activities in our country is animal breeding. The animal manure from cattle breeding enterprises can be used as an organic material in producing biogas. The energy needs of agricultural enterprises can be met by establishing biogas production facilities. At the same time, environmental pollution can also be prevented. With today's information and technology, it is possible to investigate the areas suitable for biogas energy stations. The aim of this study is to determine the potential areas in the Euphrates Basin which are suitable for biogas plants. The Euphrates Basin covers Adiyaman, Sanliurfa, Gaziantep and Kilis provinces. In this context, the borders of the provinces subjected to the study and the topographic properties of the region were drawn using ARCMAP 10.0 software. Furthermore, cattle numbers were entered into the Geographic Information Systems (GIS) database. The potential biogas areas in each province were determined and these areas were tried to be interpreted in different colours. In the study area, it was determined that the potential biogas energy of 862863.7 MJ or electricity energy of 239684.4 kWh would be obtained from approximately 2061883.4 tonnes of animal waste per year. It was determined that these values were equal to an amount of the annual energy capacity needs of 103 houses. Biogas energy production facilities can be established in the places which have an intensive agricultural activity and this can eliminate environmental pollution problems.

(Parlar Scientific Publications (P S P), 2019) Ucak, Ali Beyhan; Saltuk, Burak
The present research was carried out to determine water-stress tolerance of malting barley genotypes (Durusu, Firat, Atilir) grown under (winter planting), different water conditions [no water stress (I-100); strong water-stress (I-0)] in the years 2016 and 2017. Variance analyses revealed significant differences between the genotypes (P<0.01). As the average of two years, the greatest yield was obtained from no water-stress x genotype interaction (I(100)x Durusu) with 5613.50 kg ha(-1), the lowest yield was obtained from strong water stress x genotype interaction (I(0)x Atilir) with 3848.82 kg ha(-1). Again as the average of two years, the greatest chlorophyll content was obtained from no water stress x genotype interaction (I(100)x Durusu) with 45.23 spad, the lowest value was obtained from strong water-stress x genotype interaction (Iox Atilir) with 35.80 spad. The greatest crop water stress index was obtained from strong water stress x genotype interaction (I(0)x Atilir) with 0.47, the lowest value was obtained from no water-stress x genotype interaction (I(100)x Durusu) with 0.24. The lowest protein content was obtained from no water-stress x genotype interaction (I(00)x Durusu) with 9.36 %, the greatest value was obtained from strong water stress x genotype interaction (I(0)x Atilir) with 12.98 %. The Durusu genotype with optimum water use efficiency and prominent with crop water stress index, chlorophyll, chlorophyll content and low protein content both in no water-stress and strong water stress treatments was identified as water stress-resistant and the genotype was considered to have reliable characteristics potentially to be used in further water stress-resistance studies. On teh other hand Atilir (malting barley) genotype was identified as water stress-sensitive. As a result decreased protein content and total protein content in plants under no water-stress treatments.

(Agriculture for Life, Life for Agriculture, 2016) Aydın, Yusuf; Saltuk, Burak; Atılgan, Atılgan; Yücel, Ali; Özrenk, Koray
Growing of Siirt type of pistachio has a significant potential in the agriculture of Siirt province. As a result of the studies on this issue performed by public and legal institutions in recent years, while about 2000 tons of products were taken from the area in 4545.3 ha in 2002, these values reached about 11.000 tons of products in 25.000 ha by the end of 2014. Considering the climatic conditions of the region, the fact that summer is very hot and irregularity in the precipitation regime further increase the importance of irrigation and make it necessary for cultural practices in farming. However, pistachio orchards are not irrigated or tried to be contented with a little water due to the reasons such as the topographical structure of the area where farming is performed, irrigation water constraints, and any other reasons. The questionnaire study was carried out to determine the local farmers' tendencies on Siirt pistachio irrigation, problems faced, and the solution offers. For this purpose, the questionnaire form consisting of 40 questions was prepared, and data were collected using the Simple Random Sampling method. By this method, questionnaires were filled in by making face to face interviews with 177 farmers in 73 villages of 7 districts where farming is intensively performed. The obtained data were analyzed using MINITAB 16 statistical program. As a result of the statistical analyses, an attempt to contribute to the solution of the problems was made by developing solutions to identified problems.

(Latvia Univ Agriculture, 2016) Atilgan, Atilgan; Saltuk, Burak; Oz, Hasan; Artun, Ozan
The study was carried out in the Tigris basin and covered four cities (Diyarbakir, Mardin, Batman, Siirt and Sirnak). The potential pollution impacts of the cattle breeding enterprises in the research area on the Batman, Botan, Garzan and Tigris Rivers were examined. In this context, the borders of the research provinces and current water resources were drawn with ARCMAP 10.0 software by making geographical adjustments. In order to enable each province's questioning to be done independently from other provinces and water resources, all borders were divided into separate layers on the basis of provinces, districts, and villages. Furthermore, in accordance with the purpose of this study in the database the number of cattle at the cattle breeding enterprises close to water resources (minimum 150 meters-maximum 5 kilometers) was entered into the Geographical Information System (CIS) database and interpreted taking into account the average waste to be created by the cattle. In this study, the potential risk areas to be created for the environment and water resources were tried to be determined when the manure generated in the cattle breeding enterprises operating in the research area is not stored and utilized appropriately. It was found that the water resources, particularly in the villages of Batman and Diyarbakir provinces, faced a higher risk of contamination. A high level of contamination risk was determined in the section of the Tigris River passing through Ergani, Hani, and Bismil districts of Diyarbakir Province and in the upper section of the Botan River passing through Kozluk district of Batman Province and its villages. Furthermore, attention was drawn to the issue of environmental pollution caused by animal manure, and the measures to be taken not to experience these and similar situations were mentioned.

MANURE FROM LIVESTOCK FARMING IN THE EUPHRATES BASIN AND ITS POTENTIAL ENVIRONMENTAL IMPACT ON WATER RESOURCES
(Univ Agricultural Sciences & Veterinary Medicine Bucharest, 2016) Saltuk, Burak; Atilgan, Atilgan; Aydin, Yusuf; Koca, Y. Kenan; Kose, Nihat
Food of animal origin derived from livestock farming establishments is necessary to meet the needs of human beings. The wastes generated during the production stages of cattle breeding (manure, ground covers, etc.) create a danger to the environment and water resources when they are released to the environment randomly. Therefore, the waste generated by livestock farming establishments should be stored in a controlled manner and should not cause environmental pollution. The research was carried out in the Euphrates basin and covered four provinces (Adiyaman, Sanliurfa, Gaziantep, and Kilis) and 35 districts. In the context of this study, the number of the cattle bred in the establishments in 328 villages which are at least 150 m and at the most 5 km distance to the flow path of the Euphrates was taken into consideration. In the study, Erdas Imagine 9.3 and ArcMAP 10.0 software were used; the number of the cattle and the distance to the rivers were evaluated as a layer. The subject of the study was the investigation of the potential pollution effects of the cattle breeding on the Euphrates River and its tributaries, and it was carried out to determine risky, non-risky and partially risky areas and attract attention to this issue. As a result, it was concluded that 4 districts and villages of Sanliurfa Region would be classified as risky areas, 3 districts and villages of Gaziantep Region would be classified as partially-risky areas, and 3 districts and villages of Adiyaman Region and all districts and villages of Kilis Region would be classified as non-risky areas.

Multi-criteria decision system for greenhouse site selection ın Lower Euphrates Basin using geographic ınformation systems (GIS)
(African Journal of Agricultural Research, 2018-11-22) Saltuk, Burak; Artun, Ozan
Greenhouses have become quite a sought-after agricultural sector due to government support and private company preferences in recent years in Turkey. Greenhouse activities are only limited with Mediterranean and Aegean regions of Turkey and it is not much preferred in the inner regions. Due to these regions being preferred by people, mainly as tourism and settlement areas, it has become very important to find new areas for greenhouse operations. The climatic and topographical conditions in the Southeastern Anatolia Region, are appropriate in terms of greenhouses. In this context, the Lower Euphrates Basin is selected as the study area. It covers 4 provinces (Adiyaman, Gaziantep, Kilis ve Sanliurfa) and is one of the preferred regions for greenhouse operations in recent years. In this study, the climatic conditions and the production capacity of the Antalya province, which has the most greenhouse production areas of the Mediterranean Region and Turkey, are taken into consideration and the four provinces of the Lower Euphrates basin were investigated for their compatibility with the desired conditions in terms of green housing. Climate, soil, wind, altitude, slope, aspect, distance to rivers and lakes data are important in choosing the greenhouse location. A Geographic Information System (GIS) -based Multi-criteria evaluation for greenhouse site selection were applied in the study area by using these data. The validity of the results has been checked over with the field studies and also compared with the climatic conditions and production capacity of Antalya Province. The suitable, non-suitable or partially suitable areas for greenhouse siting in the basin were determined in terms of GIS, for guidance to producers and researchers in the future.
