Öğe Arıtma Çamuru Uygulamalarının Topraktaki Bazı Mikro Besin Elementleri Üzerine Etkisi(2024) Gezer, Erhan; Konukcu, Fatih; Adiloğlu, Aydın; Dinçer, Ali RızaBu çalışma, Trakya Bölgesi toprakları üzerine değişen miktarlarda (2, 4, 8 ton da-1) arıtma çamuru uygulanması neticesinde, bazı mikro elementler (Cu, Fe, Mn ve Zn) üzerine etkilerinin belirlenmesi maksadıyla bölgenin Tekirdağ ilinde gerçekleştirilmiştir. Mikro elementler, toprak bünyesinde eser miktarda bulunmasına rağmen eksiklik koşullarında büyük verim kayıplarına neden olmaktadır. Çalışma, tesadüf blokları bölünmüş parseller deneme desenine göre 3 tekerrürlü olarak gerçekleşmiştir. Topraklara arıtma çamuru uygulaması sonucunda yarayışlı bakır, demir ve çinko kapsamlarında artışlar gerçekleşmiş ve bu durum istatistiksel açıdan önemli bulunmuştur (p<0.01). Arıtma çamuru uygulanan toprakların yarayışlı Fe kapsamı “orta” düzeyden “fazla” düzeye, yarayışlı Zn kapsamı “yetersiz” düzeyden “yeterli” düzeye yükselmiştir. Toprakların yarayışlı Mn kapsamında ise istatiksel açıdan önemli (p<0.01) kabul edilen bir azalma gözlenmiş ve topraktaki içeriği “yeterli” düzeyden “az” düzeyine gerilemiştir. Trakya Bölgesi toprakları üzerine arıtma çamuru uygulanmasının toprak mikro bitki besin element içeriklerini büyük ölçüde olumlu etkilediği gözlemlenmiştir. Bölgede yoğun tarım uygulamalarının devam ettiği göz önünde bulundurulduğunda, arıtma çamuru uygulamalarının tarımsal faaliyetlerin sürdürülebilir olması açısından oldukça önemli bir yöntem olduğu ortaya çıkmıştır.Öğe Evaluation of Agricultural Parcels in terms of Land Consolidation with Shape Analysis in Tekirdağ Province(2023) Kurşun, Erdem; Konukcu, Fatih; Altürk, BahadırShape irregularity is one of the most important factors that reduce agricultural efficiency and the sustainability of rural development. In the study, the shape of 346.740 agricultural parcels in Tekirdağ province was measured by the Parcel Shape Index (PSI) method, which integrates six different criteria (length of sides, acute angles, reflex angles, boundary points, compactness and regularity). The PSI method analyzes geometry more comprehensively than other classical shape methods. Determining the shape suitability of the parcels with this method and then the corrections to be made in the deformed parcels ensure that the negative effects of agricultural mechanization are minimized. In the research, shape suitability degrees were categorized into four groups; namely, highly irregular shapes, irregular shapes, regular shapes and near optimum shapes. It was determined that 17.27% of the parcels in the province have a highly irregular shape, 35.21% have an irregular shape, 35.54% have a regular shape and 11.98% have near optimum shape geometry. Land consolidation studies should be carried out urgently due to the shape irregularity affecting production throughout the province. PSI method can provide great benefits in the site selection before the land consolidation projects planned in Türkiye, at the scale of basin, village or rural county.Öğe Evaluation of Hayrabolu Irrigation Scheme in Turkey using comparetive performance indicators(Namık Kemal Üniversitesi, Ziraat Fakültesi, 2007) Şener, Mehmet; Yüksel, A.N.; Konukcu, FatihPerformance of Hayrabolu Irrigation Scheme of the Thrace district in Turkey was evaluated using some selected comparative indicators, classified into five groups, namely, agricultural, economic, water-use, physical and environmental performance by International Water Management Institute (IWMI). Agricultural performance, evaluated in different type of Gross Value of Production, was determined lower than that of the other respective national average. Analyses of water-use performance showed that relative water and relative irrigation supply were calculated 1.91 and 1.55 respectively, indicating that water distribution is not tightly related to crop water demand. Economic performance indicators showed that the scheme had a serious problem about the collection of water fees. Physical performance, evaluated in terms of irrigation ratio and sustainability of irrigated land, were poor. Under environmental performance studies, no damages such as waterlogging and salinity were detected in the irrigated area through excessive water use.Öğe Modeling the Effect of Climate Change on Evapotranspiration in the Thrace Region(Mdpi, 2024) Deveci, Huzur; Konukcu, FatihThe aim of this study is to determine the effect of climate change on reference evapotranspiration (ETo) and sunflower and wheat evapotranspiration (ETs and ETw, respectively) in the Trakya Region of T & uuml;rkiye. ETo Calculator (version 3.2) and CROPWAT 8.0 were used to compute ETo and ET in the reference period (1970-1990), short- (2016-2025), mid- (2046-2055), and long- (2076-2085) terms. Additionally, ETo was tested in 2012 and ETo was simulated for every 1 degrees C temperature increase up to 5 degrees C in the reference period. Calculated ETo and ET values for the future were compared with the reference period. For the future, climate data estimated by RegCM3 Regional Climate Model, A2 scenario were used. While the average ETo value of the reference period was 3.3 mm day-1, it was 3.0 mm day-1 in 2012. Compared to the reference period, ETo values change by -3% (3.2 mm day-1), 9% (3.6 mm day-1), and 21% (4.0 mm day-1) in the short-, mid-, and long-term, respectively. The 575 mm ET deficit calculated during the vegetation period of sunflower in the model reference period was forecasted to change by -11% (514 mm), +15% (660 mm), and +25% (721 mm) in the short-, mid-, and long-term, respectively. For wheat, while 59 mm of excess water was calculated in the reference period, it became 193 mm (+227%) in the short-term and a water deficit of 8 mm (-113%) and 6 mm (-110%) in the mid- and long-term, respectively. In addition, it is estimated that there will be an increase of 0.1 mm day-1 (4%) in ETo values for each 1 degrees C temperature increase compared to the reference period (1970-1990). It was concluded that climate change in the Trakya Region will not significantly affect wheat farming; however, it will cause a serious water deficit in sunflower production.Öğe Modelling the Adaptation of Some Cultural Plants Produced in Thrace Region to Climate Change(Univ Namik Kemal, 2024) Sen, Anil Saygin; Deveci, Huzur; Konukcu, FatihToday, the effects of climate change have started to be experienced and will continue to be experienced. It is estimated that many sectors will be affected by climate change. The agricultural sector is one of these sectors. Thrace Region is one of our important regions that contribute to wheat, canola, and sunflower production in Turkey. Therefore, when unpredictable situations arise with climate change, it is very important to accurately determine how the cultivation areas of these three plants, which have an important role in the agriculture and food sector, will change in the future against climate change. First of all, it is necessary to predict precisely how the climate will change, and then to determine what precautions should be taken by making plans. The aim of this study is to predict how climate change will affect the geographical distributions of wheat, canola and sunflower plants grown in the Thrace Region in the future, using a plant suitability model. For this purpose, the suitability of wheat, canola and sunflower plants for the current period (1950-2000) in the Thrace Region was determined using the Ecocrop module included in the DIVA-GIS program, and then in line with the results of the HADGEM2_ES model RCP4.5 and RCP8.5 scenarios for the next period, in the 2050s, suitability estimates were made for these three plants by using the Ecocrop module. Current and future prediction results are compared with each other. As a result, in the TR21 Thrace Region in the 2050s, in the HADGEM2_ES model RCP4.5 scenario for wheat, suitable, very suitable, and excellent areas will be replaced by not suited, very marginal, marginal areas, respectively. This will be more severe under RCP8.5 scenario. For canola, suitable and very suitable areas will be replaced by suitable and excellent areas, respectively, in the 2050s, and this positive situation will occur more in the RCP4.5 scenario. In sunflower, on the other hand, it has been predicted that the areas that are excellent current will not change in the future. It is recommended that producers, decision makers and practitioners direct the future in line with these results while planning.Öğe Mısır Bitkisinin İkinci Ürün ve Silajlık Olarak Yetiştirilmesinde Kullanılan Arıtma Çamurunun Topraktaki Makro Besin Elementleri Üzerine Etkisi(2023) Gezer, Erhan; Konukcu, Fatih; Adiloğlu, Aydın; Dinçer, Ali RızaBu araştırma, artan dozlarda uygulanan arıtma çamurlarının (2, 4, 8 ton da-1) düşük organik madde içeriğine sahip ve erozyon probleminin yoğun bir şekilde yaşandığı Trakya Bölgesi topraklarının fiziksel ve kimyasal özellikleri üzerine etkilerini belirlemek amacıyla yürütülmüştür. Deneme arazisi toprakları üzerine uygulanan arıtma çamuru, toprakların organik madde, toplam azot, yarayışlı fosfor, değişebilir potasyum içeriklerinde artışlar meydana getirmiş ve bu artış istatistiksel olarak önemli bulunmuştur (p<0.01). Atıksu arıtma çamuru uygulaması toprakların değişebilir magnezyum içeriğinde azalmaya neden olmuştur. Toprakların değişebilir kalsiyum içeriğinde ise herhangi bir değişim söz konusu olmamıştır. Araştırma sonuçlarına göre organik madde içeriği yüksek, Toprak Kirliliği Kontrol Yönetmeliği’ne uygun ve tarımda kullanılmasında bir sakınca bulunmayan arıtma çamurlarının, organik madde içeriği yetersiz durumda olan Trakya Bölgesi topraklarına uygulanması tarımda sürdürülebilirliğin ve verimliliğin artırılması için büyük önem taşımaktadır.Öğe Prediction of The Effect of Climate Change on Wheat Yield in Thrace Region(2023) Coskun, Ahmet; Deveci, Huzur; Konukcu, FatihThe aim of this study is to model the effect of climate change on the yield of wheat in Thrace Region. For this purpose, the 2020-2021 period wheat yield data taken from the farmer's field was calibrated by comparing it with the one calculated with the LINTUL model using the climate data of the same year and then yield values were estimated for the 2031-2040, 2041-2050, 2051-2060, 2061-2070 and 2071-2080 periods with the climate data obtained from the RCP4.5 and RCP8.5 scenarios of HadGEM2-ES and MPI-ESM-MR global climate models. Yield estimations were made in two ways without changing the sowing and harvest dates: In the first, yield calculations were made by considering the average lowest and highest temperature, solar radiation and precipitation change. In the second, while the solar radiation values were kept constant for the period 2004-2021, average minimum and maximum temperature and precipitation changes were taken into account. In the first approach, the estimated yield changes for the RCP4.5 and RCP8.5 scenarios of the HadGEM2-ES model were calculated between 1.5%-7.5% and -7.5%-7.5%, respectively, while for the MPI-ESM- MR model they were simulated between 9.0%-13.4% and 3.0%-16.4%in the same order. It was concluded that in yield estimations, the effect of solar radiation along with temperature and precipitation must be taken into account. For food security, the agricultural lands of the Thrace Region should not be used beyond their purposes since yield is forecasted to increase generally with climate change unlike other parts of Turkiye.Öğe Trakya Bölgesi İçme ve Kullanma Suyu İhtiyacının Belirlenmesi(Namık Kemal Üniversitesi, Ziraat Fakültesi, 2007) İstanbulluoğlu, Ahmet; Konukcu, Fatih; Kocaman, İsrafil; Göçmen, ErhanBu çalışmada Trakya Bölgesinin kent ve kır insanı ile onun hayvan varlığının gelecekte ihtiyacı olan içme ve kullanma suyu miktarının, bilimsel bir perspektifle saptanması amaçlanmıştır. Bunun için bölgenin gelecekteki nüfus projeksiyonları yapılarak, gerekli su ihtiyaçları tahmin edilmiştir. Hesaplamalara göre 2020, 2030, 2040 ve 2050 yılları için toplam içme ve kullanma suyu miktarları sırasıyla 1.45, 1.94, 2.58 ve 3.44 km3 olarak bulunmuştur. Artan nüfus ve aldığı göçler nedeniyle içme ve kullanma suyuna olan talebin hızla artması yanında, tarımın ve yoğun endüstrileşmenin ihtiyaç duyduğu su miktarı da dikkate alındığında, bölgenin toplam tatlı su potansiyeli olan 4.0 km3 suyun çok yetersiz kalacağı ve şimdiden önlem alınmadığı taktirde büyük su krizlerinin yaşanacağı öngörülmektedir. Olası küresel iklim değişikliğinin su kaynaklarına olan etkileri de dikkate alındığında çok vahim bir durum ortaya çıkmaktadır. Su krizini aşmak amacıyla kamu kurum ve kuruluşları ile sivil toplum örgütlerinin birlikte stratejiler geliştirerek uygulamaya geçirmeleri önerilmiştir.
