    Alternative Evaluation of Olive Pomace (Pirina) as Production Waste
    (Middle Pomeranian Sci Soc Env Prot, 2021) Atilgan, Atilgan; Rolbiecki, Roman; Saltuk, Burak; Ertop, Hasan; Markovic, Monika
    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.

    Environment- and Genotype-Dependent Irrigation Effect on Soybean Grain Yield and Grain Quality
    (Mdpi, 2023) Kocar, Maja Matosa; Josipovic, Marko; Sudaric, Aleksandra; Plavsic, Hrvoje; Berakovic, Ivica; Atilgan, Atilgan; Markovic, Monika
    This four-year study with four elite soybean lines with different maturities was conducted to investigate the impact of deficit (a field water capacity, or FWC, of 60%) and full irrigation (an FWC of 80-100%) on soybean grain yield and grain quality (grain protein and oil contents and crude protein and oil yields), depending on the environmental conditions and genotype. Overall, the irrigation effect was positive for the grain yield and grain protein content but negative for the grain oil content. The differences between the full and deficit irrigation were only 2.9% for the grain yield, 2.8% for the crude protein yield and 1.7% for the crude oil yield. The results indicate that deficit irrigation could be the best option for optimizing soybean production in environments similar to the tested one. In such conditions, further rationalization of soybean production could be achieved by choosing the C2 genotype (0 maturity group), which, combined with deficit irrigation, had the highest grain, crude protein and crude oil yields.

    Field Performance Evaluation of Low-Cost Soil Moisture Sensors in Irrigated Orchard
    (Mdpi, 2024) Markovic, Monika; Matosa Kocar, Maja; Barac, Zeljko; Turalija, Alka; Atilgan, Atilgan; Jug, Danijel; Ravlic, Marija
    Measuring the soil water content (SWC) is a fundamental component of the sustainable management of water resources, soil preservation, and high irrigation efficiency. Non-destructive SWC measurements using soil moisture sensors (SMSs) enables timely irrigation and reduces overirrigation and water stress. Within this context, the performance of four commercial single-point soil moisture sensors (Watermark and tensiometer (Irrometer Company, Inc., Riverside, CA, USA), SM150 (Delta-T Devices, Cambridge, UK)), FieldScout TDR300 (Spectrum Technologies, Aurora, IL, USA) and one soil profile PR2 probe (Delta-T Devices, Cambridge, UK) were tested under anthropogenic eutric cambisol with a silty clay loamy texture (20, 30, and 40 cm) to evaluate accuracy and sensitivity to changes in the SWC in an irrigated apple orchard. The Watermark and tensiometer were additionally tested in the laboratory to convert soil water tension (kPa) to the volumetric soil water content (%vol.). In general, all tested SMSs responded to changes in the SWC, with sensor-to-sensor differences. The Watermark and tensiometer underestimated the SWC, while the TDR overestimated the SWC. The SM150 and PR2 showed high accuracy, i.e., SM150-RMSE-2.24 (20 cm), 2.18 (30 cm) and 2.34 (40 cm), MSE-5.02 (20 cm), 2.93 (30 cm) and 1.89 (40 cm), and PR2-RMSE-1.8 (20 cm), 1.3 (30 cm) and 1.55 (40 cm), MSE-3.23 (20 cm), 1.7 (30 cm) and 2.39 (40 cm) at all observed soil depths.

    Investigation of Annual Lake Water Levels and Water Volumes with Sen Innovation and Mann-Kendall Rank Correlation Trend Tests: Example of Lake Egirdir, Turkey
    (Mdpi, 2022) Yucel, Ali; Markovic, Monika; Atilgan, Atilgan; Rolbiecki, Roman; Ertop, Hasan; Jagosz, Barbara; Ptach, Wieslaw
    Lakes are the most important freshwater resources for humans. It is stated that together with population growth, unplanned urbanization, excessive water consumption, industrialization, and unconscious irrigation, global climate change causes changes in the water levels and volumes of lakes. Lake Egirdir in Turkey, which is important in terms of drinking and irrigation water use, was chosen as the study area. Lake Egirdir water level (LWL) and water volume (LWV) values measured between 1988-2019 were used. Dependencies in the annual LWL and LWV were examined by autocorrelation analysis, and trend changes were examined by regression analysis, the Mann-Kendall rank correlation test, and the Sen innovation trend test. The research has shown a significant decrease since 2000 in LWL and since 1990 in LWV. The LWL has decreased by -1.272 to -3.514 m and the LWV has decreased by -72.980 to -1082.134 hm(3) in approximately 32 years. The actions to be taken based on the values determined in this study will help protect the water resources of lakes. As a result of the tests used in our study, it was determined that there were decreases in both the water level and the volume of the lake. The climatic changes in the lake basin and the decrease in the water resources feeding the lake are shown as the biggest factor in these reductions.

    The Benefit of Mycorrhizal Fungi and Beneficial Soil Bacteria in Drought Exposed Lettuce (Lactuca sativa var. capitata) Is Genotype and Environment Dependent
    (Mdpi, 2023) Kojic, Antonija; Markovic, Monika; Marcek, Tihana; Velic, Natalija; Lojkova, Lea; Atilgan, Atilgan; Japundzic-Palenkic, Bozica
    Morphological and biochemical responses were assessed in an iceberg (G(IL)) and butterhead (G(BL)) lettuce (Lactuca sativa var. capitata) treated with commercially available soluble preparation of mycorrhizal fungi and beneficial soil bacteria (MT) grown in three irrigation treatments considered in greenhouse (continental Croatia, 2022): I-100-control treatment (100% volumetric water content-VWC); I-80-80% VWC, moderate drought and I-60-60% VWC, severe drought), in two growing cycles. MT was applied during lettuce drought-sensitive stages, i.e., transplanting and heading. Study results show that MT improved lettuce growth-related traits, yet the results are genotype and growing-cycle dependent. The beneficial effect of MT was also noted for root length, weight, and diameter which confirms the mycorrhizal role in improving the plant water uptake. Both lettuce genotypes responded to water deficit by overproduction of MDA and proline content, whereby the response of tested variables was growing cycle and genotype-specific. Both genotypes in severe drought treatment (MT-I-60) responded with higher MDA in the first growing cycle and lower MDA content in the second growing cycle. MT-I-60 treatment reduced proline accumulation in GBH in both growing cycles, while increased accumulation in GIL during the second growing cycle. The responses of lettuce to MT are genotype-specific and shaped by environmental conditions.

    The effect of climate change on stream basin hydrometeorological variables: The example of Dim Stream (Turkey)
    (European Regional Centre Ecohydrology Polish Acad Sciences, 2024) Atilgana, Atilgan; Yuecelb, Ali; Kocieckac, Joanna; Rolbieckid, Roman; Senyigite, Ulai; Tas, Ismail; Markovic, Monika
    Climate change is causing serious problems in various economic sectors in particular involving water management. For this reason, it is extremely important to conduct research to identify climate change trends and better understand them. This study was carried out in the Dim Stream basin in the Western Mediterranean region (Turkey), which is particularly vulnerable to climate change. The study used flow data from two flow observation stations (FOS) and meteorological records such as wind speed, average flow, precipitation, temperature, evaporation, radiation, and relative humidity for 1984-2017. These data showed the changes between flow and hydrometeorological variables using linear regression analysis, coefficient of variation, t-test and correlation analysis. It has been determined that there has been a rapid decrease in the average flow of the FOS number 09006 since 1995 and the average flow of the FOS number 09-013 since 1999. Also, it was demonstrated that the average relative humidity (RHave), ave ), average temperature (Tave), ave ), average precipitation (Pave), total precipitation (Pt) and maximum precipitation (P max ) meteorological variables were most affected by climate change in the basin. Furthermore, it was found that the most changes were Qy ave (67.60%), T m i n (48.23%), P max (36.43%), P ave (33.91%), Pt t (33.90%), and RH ave (2.63%) in FOS numbered 09-013. Moreover, it was concluded that climate change variability had developed trends towards a rapid decrease in the flow values at the flow observation stations in Dim Stream. These results show that plans and measures for the efficient and sustainable management of water resources in this region must be implemented immediately.
