    Assessment of the Crop Water Stress Index for Green Pepper Cultivation Under Different Irrigation Levels
    (Mdpi, 2025) Boyaci, Sedat; Kociecka, Joanna; Kesicka, Barbara; Atilgan, Atilgan; Liberacki, Daniel
    The objective of this study was to evaluate the effects of different water levels on yield, morphological, and quality parameters, as well as the crop water stress index (CWSI), for pepper plants under a high tunnel greenhouse in a semi-arid region. For this purpose, the irrigation schedule used in this study includes 120%, 100%, 80%, and 60% (I120, I100, I80, and I60) of evaporation monitored gravimetrically. In this study, increasing irrigation levels (I100 and I120) resulted in increased stem diameter, plant height, fruit number, leaf number, and leaf area values. However, these values decreased as the water level dropped (I60 and I80). At the same time, increased irrigation resulted in improvements in fruit width, length, and weight, as well as a decrease in TSS values. While total yield and marketable yield values increased at the I120 water level, TWUE and MWUE were the highest at the I100 water level. I80 and I120 water levels were statistically in the same group. It was found that the application of I100 water level in the high tunnel greenhouse is the appropriate irrigation level in terms of morphology and quality parameters. However, in places with water scarcity, a moderate water deficit (I80) can be adopted instead of full (I100) or excessive irrigation (I120) in pepper cultivation in terms of water conservation. The experimental results reveal significant correlations between the parameters of green pepper yield and the CWSI. Therefore, a mean CWSI of 0.16 is recommended for irrigation level I100 for higher-quality yields. A mean CWSI of 0.22 is recommended for irrigation level I80 in areas where water is scarce. While increasing the CWSI values decreased the values of crop water consumption, leaf area index, total yield, marketable yield, total water use efficiency, and marketable water use efficiency, decreasing the CWSI increased these values. This study concluded that the CWSI can be effectively utilised in irrigation time planning under semi-arid climate conditions. With the advancement of technology, determining the CWSI using remote sensing-based methods and integrating it into greenhouse automation systems will become increasingly important in determining irrigation times.

    Calculation of the Potential Biogas and Electricity Values of Animal Wastes: Turkey and Poland Case
    (Mdpi, 2023) Ertop, Hasan; Atilgan, Atilgan; Kociecka, Joanna; Krakowiak-Bal, Anna; Liberacki, Daniel; Saltuk, Burak; Rolbiecki, Roman
    This research aimed to analyze the potential amount of electrical energy from biogas energy obtained from animal wastes in Turkey and Poland. Animal waste values were calculated by taking into account the recommended literature values. In determining the biomass energy potential of livestock enterprises in Turkey and Poland, FAO's 2012-2021 data were taken into account. The animal breeds selected as material in this study were cattle, goat, sheep, chicken, duck, goose, turkey, horse, pig, mule and donkey. Considering 10-year calculations, the potential amount of biogas energy that can be obtained from animal wastes for Turkey is 28,845,975 GJ, which is equivalent to 8,105,058 MWh of electrical energy. In Poland, the potential amount of biogas energy that can be generated from animal waste is 13,999,612 GJ, which is equivalent to 3,902,020 MWh of electricity. Moreover, it is estimated that the percentage of the potential amount of electricity to be obtained in 2021 to cover the amount of electricity consumed is 0.303% for Turkey and 0.392% for Poland. For 2021, the amount of economic gains that can be from electricity obtained was also calculated, and it was determined that this value can be 78,650,302 Euro for Turkey and 62,182,435 Euro for Poland. At the same time, it was calculated that the electricity needs of 406,170 houses in Turkey and 171,958 houses in Poland can be met in 2021. As a result, it is thought that the potential electricity to be obtained will contribute to determining energy gains and investment plans for biogas plants.

    Determination of global warming potential of dairy cattle farms
    (Inderscience Enterprises Ltd, 2023) Atilgan, Atilgan; Rolbiecki, Roman; Ertop, Hasan; Kociecka, Joanna; Aksoy, Ercument; Saltuk, Burak
    Dairy cattle's breeding is carried out intensively in the Eastern Anatolia Region (Turkey) and is a source of methane emissions. This study calculated global warming potentials arising from enteric fermentation and manure management of existing dairy cattle farms in this region between 2016 and 2020 using the tier-1 method defined by the IPCC. As a result, it has been found that the global warming potential of this region is 20,287.68 x 103 tons of CO2 in total. The total CH4 value in the research area was 966.08 x 103 tons. Furthermore, it has been determined that 98.02% of these emissions are enteric CH4, and 1.98% is CH4 originating from fertiliser management. Therefore, it is seen that enteric CH4 constitutes a large part of the total CH4 emissions. For this reason, CH4 emissions can be controlled by choosing silage feeds in feed selection and adding minerals and vitamins to silage feeds.

    Determination of Performance of Different Pad Materials and Energy Consumption Values of Direct Evaporative Cooler
    (Mdpi, 2024) Jakubowski, Tomasz; Boyaci, Sedat; Kociecka, Joanna; Atilgan, Atilgan
    The purpose of this study is to determine the performances of luffa and greenhouse shading netting (which can be used as alternatives to commercial cellulose pads, that are popular for cooling greenhouses), the contribution of external shading to the evaporative cooling performance, and the energy consumption of the direct evaporative cooler. In this experiment, eight different applications were evaluated: natural ventilation (NV), natural ventilation combined with external shading net (NV + ESN), cellulose pad (CP), cellulose pad combined with external shading net (CP + ESN), luffa pad (LP), luffa pad combined with external shading net (LP + ESN), shading net pad (SNP), and shading net pad combined with external shading net (SNP + ESN). The cooling efficiencies of CP, CP + ESN, LP, LP + ESN, SNP, and SNP + ESN were found to be 37.6%, 45.0%, 38.9%, 41.2%, 24.4%, 29.1%, respectively. Moreover, their cooling capacities were 2.6 kW, 3.0 kW, 2.8 kW, 3.0 kW, 1.7 kW, 2.0 kW, respectively. The system water consumption values were 2.9, 3.1, 2.8, 3.2, 2.4, 2.4 l h-1, respectively. The performance coefficients of the system were determined to be 10.2, 12.1, 11.3, 11.9, 6.6, 7.8. The system's electricity consumption per unit area was 0.15 kWh m-2. As a result of the study, it was determined that commercially used cellulose pads have advantages over luffa and shading net materials. However, luffa pads can be a good alternative to cellulose pads, considering their local availability, initial cost, cooling efficiency, and capacity.

    Determination of the Effect of a Thermal Curtain Used in a Greenhouse on the Indoor Climate and Energy Savings
    (Mdpi, 2023) Boyaci, Sedat; Atilgan, Atilgan; Kociecka, Joanna; Liberacki, Daniel; Rolbiecki, Roman; Jagosz, Barbara
    In order to reduce the impact of outdoor extreme weather events on crop production in winter, energy saving in greenhouses that are regularly heated is of great importance in reducing production costs and carbon footprints. For this purpose, the variations in indoor temperature, relative humidity and dew point temperature in the vertical direction (2 m, 4 m, 5.7 m) of thermal curtains in greenhouses were determined. In addition, depending on the fuel used, the curtains' effects on heat energy consumption, heat transfer coefficient, carbon dioxide equivalents released to the atmosphere and fuel cost were investigated. To reach this goal, two greenhouses with the same structural features were designed with and without thermal curtains. As a result of the study, the indoor temperature and relative humidity values in the greenhouse with a thermal curtain increased by 1.3 degrees C and 10% compared to the greenhouse without a thermal curtain. Thermal curtains in the greenhouse significantly reduced fuel use (59.14-74.11 m3 center dot night-1). Considering the heat energy consumption, the average heat energy consumption was 453.7 kWh center dot night-1 in the greenhouse with a curtain, while it was 568.6 kWh center dot night-1 in the greenhouse without a curtain. The average heat transfer coefficient (U) values were calculated at 2.87 W center dot m-2 degrees C with a thermal curtain and 3.63 W center dot m-2 degrees C without a thermal curtain greenhouse. In the greenhouse, closing the thermal curtain at night resulted in heat energy savings of about 21%, related to the decrease in U values. The use of a thermal curtain in the greenhouse reduced the amount of CO2 released to the atmosphere (116.6-146.1 kg center dot night-1) and fuel cost (USD 21.3-26.7 center dot night-1). To conclude, extreme weather events in the outdoor environment adversely affect the plants grown in greenhouses where cultivation is performed out of season. A thermal curtain, used to reduce these adverse effects and the amount of energy consumed, is essential in improving indoor climate conditions, providing more economical greenhouse management and reducing the CO2 released into the atmosphere due to fuel use.

    Determination of the Effects of Different Irrigation Levels and Vermicompost Doses on Water Consumption and Yield of Greenhouse-Grown Tomato
    (Mdpi, 2024) Boyaci, Sedat; Kociecka, Joanna; Atilgan, Atilgan; Niemiec, Marcin; Liberacki, Daniel; Rolbiecki, Roman
    This study was conducted in pots under a polycarbonate greenhouse to determine the effects of different irrigation levels and vermicompost doses on the morphological and phenological characteristics, water consumption, water use efficiency, and yield parameters of tomato plants. For this purpose, different irrigation levels of 100%, 75%, 50% (I100: full irrigation, I75, I50) and vermicompost (VC) doses of 0, 10% and 20% (VC0, VC10 and VC20, w/w) were applied as the treatments. The study's results determined the irrigation levels and vermicompost doses affected the tomato plants' morphological and fruit quality parameters. The highest and lowest plant water consumption (ET) values for the treatments were determined as 47.8 L (I100VC10) and 21.2 L (I50VC0), respectively. Moreover, irrigation water levels and vermicompost doses significantly influenced the total yield of tomatoes. The highest and lowest total and marketable yields were obtained from the I100VC20 and I50VC0 irrigation levels and vermicompost doses. Similarly, the highest and lowest total water use efficiencies were achieved from the I100VC20 (21.9 g L-1) and I50VC0 (11.0 g L-1) treatments. Furthermore, the highest and lowest marketable water use efficiencies were obtained from the I100VC20 (21.9 g L-1) and I50VC0 (7.8 g L-1) treatments. The yield response factor (ky) was found to be 1.42. Although the highest efficiency was achieved from 100% full irrigation and a 20% vermicompost dose in the study, it is suggested that 75% irrigation level and 10% fertilizer doses can also be applied in places where water is limited and fertilizer is expensive. The results revealed that the appropriate irrigation level and vermicompost doses could reliably be used to enhance tomato yield.

    Energy Efficiency in Greenhouses and Comparison of Energy Sources Used for Heating
    (Mdpi, 2025) Boyaci, Sedat; Kociecka, Joanna; Jagosz, Barbara; Atilgan, Atilgan
    Sustainability in greenhouse farming, one of the areas where the most energy is needed in the agricultural sector, can be achieved by increasing energy efficiency. Due to increasing energy costs in T & uuml;rkiye and worldwide, increasing energy efficiency in greenhouses is seen as possible using renewable energy sources that do not produce waste instead of fossil energy sources. This study determined the heat-energy demand in the provinces of T & uuml;rkiye with continental (K & imath;r & scedil;ehir and K & uuml;tahya) and Mediterranean (Antalya and Mersin) climates. For this purpose, the heat-energy requirement was calculated for greenhouse types with three different insulation properties (S-1: roof and side walls polyethylene, S-2: roof polyethylene, side walls polycarbonate, and S-3: roof polyethylene, side walls polycarbonate, and thermal curtain). Then, the amount and cost of fossil (coal, fuel oil, and natural gas) and renewable energy sources (geothermal and biogas) to be used in obtaining this energy, the heating cost for unit tomato yield, and the amount of carbon dioxide (CO2) released into the atmosphere were compared. According to the results obtained, the highest heat-energy requirement was 356.5 kWh m(-2) year(-1) in the S-1 greenhouse in the K & uuml;tahya province, and the lowest was 46.3 kWh m(-2) year(-1) in the S-3 greenhouse in the Mersin province. Depending on energy conservation, 6% of energy savings can be achieved in S-2 and 29% in S-3 compared to S-1. The highest heating cost for producing one kilogram of tomatoes was 0.70 USD kg(-1) in fuel oil and K & uuml;tahya province (S-1). The lowest was calculated as 0.06 USD kg(-1) in geothermally heated greenhouses in K & imath;r & scedil;ehir and K & uuml;tahya provinces (S-3). The highest CO2 to be released into the atmosphere with fuels was equal to 253.1 kg m(-2) year(-1) in coal fuel in K & uuml;tahya province (S-1). The lowest was calculated as 1.1 kg m(-2) year(-1) in geothermally heated greenhouses in K & imath;r & scedil;ehir and K & uuml;tahya provinces (S-3). The results of this research can be used to develop feasibility studies for greenhouse companies, greenhouse sector policies, policymakers, environmental protection, and taking precautions against the climate crisis.

    (Mdpi, 2025) Atilgan, Atilgan; Boyaci, Sedat; Famielec, Stanislaw; Krakowiak-Bal, Anna; Ziemianczyk, Urszula; Kociecka, Joanna; Kurpaska, Slawomir
    The search for waste management opportunities is crucial for achieving environmentally friendly waste practices and ensuring the country's energy security. This research aimed to valorize biomass and waste generated in greenhouses and to analyze the potential for electricity production from this waste. The analyses compared the situations in Turkey and Poland, where greenhouse production of vegetables is developing and constitutes an important link in agricultural activities, despite differences in climatic conditions. The cultivation of vegetables and flowers under cover is rapidly expanding in both countries and, with changing climatic conditions, is expected to shape the future of agriculture. In addition to estimating the energy that can be obtained, the study also evaluated the economic benefits of such a solution and the volume of avoided CO2 emissions from fossil fuels. The issue of utilizing these wastes is significant because current methods of their management do not lead to energy production, so their considerable energy potential is wasted, as highlighted in this study. Moreover, there is a lack of similar studies in the literature. The plant species chosen as materials in this study were tomatoes, peppers, eggplant, watermelon, and melon in the case of Turkey. For Poland, the analysis was conducted for tomatoes and greenhouse cucumbers. These crops represent the largest cultivated areas under cover in the respective countries. Results indicated that the average yearly amount of vegetable residue is approximately 463 thousand Mg in Turkey, and 77 thousand Mg in Poland. The estimated annual electricity potential is 430 GWh in Turkey and 80 GWh in Poland. Considering the efficiency of power generation in a typical power plant, the real amount of electricity to be obtained is 0.46 MWh per Mg of waste in Turkey and 0.52 MWh in Poland.

    (Mdpi, 2024) Boyaci, Sedat; Kociecka, Joanna; Atilgan, Atilgan; Liberacki, Daniel; Rolbiecki, Roman; Saltuk, Burak; Stachowski, Piotr
    An experiment was conducted to determine the effect of water stress on yield and various physiological parameters, including the crop water stress index for tomatoes in the Central Anatolian region of Turkey. For this purpose, the irrigation schedule used in this study includes 120%, 100%, 80%, and 60% (I120, I100, I80, I60) of evaporation from the gravimetrically. Water deficit was found to cause a stress effect in tomato plants, which was reflected in changes in plants' morphological and pomological function (such as stem diameter, fruit weight, pH, titratable acidity, and total soluble solids). Irrigation levels had a significant effect on the total yield of tomatoes. The lowest water use efficiency (WUE) was obtained from the I60, while the highest WUE was found in the I100 irrigation level. The CWSI was calculated using an empirical approach from measurements of infrared canopy temperatures, ambient air temperatures, and vapor pressure deficit values for four irrigation levels. The crop water stress index (CWSI) values ranged from -0.63 to a maximum value of 0.53 in I120, from -0.27 to 0.63 in I100, from 0.06 to 0.80 in I80, and from 0.37 to 0.97 in I60. There was a significant relation between yield and CWSI. The yield was correlated with mean CWSI values, and the linear equation Total yield = -2398.9CWSI + 1240.4 can be used for yield prediction. The results revealed that the CWSI value was useful for evaluating crop water stress in tomatoes and predicting yield.

    The Benefits of Green Roofs and Possibilities for Their Application in Antalya, Turkey
    (Mdpi, 2025) Ertop, Hasan; Atilgan, Atilgan; Jakubowski, Tomasz; Kociecka, Joanna
    Rapid population growth, urbanization, and industrialization have many negative environmental effects. These adverse effects are felt more in urban areas than in rural areas. Considering the high rate of urban development, the idea that green roof structures can be used on rooftops is important in reducing the current negative effects. In addition, water retention on these roof areas can be helpful in the face of drought periods. In this study, the amount of water that can be retained on a 100 m2 roof area in Antalya Province, Turkey was calculated. As a result, it was determined that August is the month when the least water can be retained due to rainfall. It was calculated that between 0.168 m3 and 0.363 m3 of water can be retained in August. Furthermore, the month in which the most water can be retained due to rainfall is December, and the amounts of water that can be retained are between 5.762 m3 and 21.640 m3. These calculated values are anticipated to be important in understanding how much water can be retained in the planned green roofs. In addition, it has been determined that the energy savings that can be made for heating purposes in a 100 m2 green roof area can be between 3900 kWh and 11,250 kWh.

    The Effect of Drip Irrigation and Nitrogen Levels on the Oil and Fatty Acid Composition of Sesame and Its Economic Analysis
    (Mdpi, 2024) Tas, Ismail; Akcura, Sevim; Kaplan, Mahmut; Jagosz, Barbara; Atilgan, Atilgan; Kociecka, Joanna; Rolbiecki, Roman
    One of the oldest oilseed crops is sesame, which is mainly cultivated due to its valuable oleic/linolenic fatty acid ratio. The application of precise irrigation and fertilisation is crucial to ensure the continuity and productivity of sesame production, especially in arid and semi-arid regions. This study aimed to determine the effect of drip irrigation and nitrogen levels on sesame's oil and fatty acid composition. For this purpose, four nitrogen doses (N0: 0 kg ha-1, N30: 30 kg ha-1, N60: 60 kg ha-1 and N90: 90 kg ha-1) and three different irrigation water levels (I50, I75 and I100, which correspond to 50, 75 and 100% evaporation levels from the evaporation of the Class A pan) were applied. The highest oleic acid content (43.06%) was obtained for the I75N90 treatment. In the case of linoleic fatty acid, the greatest value (43.66%) was for I50N0 treatment. The effects of irrigation and nitrogen doses on oleic acid and linoleic acid content were inverse of each other. An increase in applied irrigation water increased the linoleic acid content. However, it caused a decrease in oleic acid content. Increasing the nitrogen dose increased the oleic acid content and caused a decrease in linoleic acid content. Furthermore, this study showed that the I50N60 treatment (50% Epan and a rate of 60 kg N ha-1) is the most effective for achieving high grain and oil yields in sesame cultivation. The results obtained provide practical guidance for farmers in sesame cultivation.

    The Effect of Irrigation and Vermicompost Applications on the Growth and Yield of Greenhouse Pepper Plants
    (Mdpi, 2025) Boyaci, Sedat; Atilgan, Atilgan; Rolbiecki, Roman; Kociecka, Joanna
    In agricultural practice, improper irrigation levels and excessive fertiliser use negatively impact water resources and soil properties, respectively. This experiment aims to determine the effects of varying irrigation levels and vermicompost doses on the growth, quality, and productivity of pepper plants grown under polycarbonate greenhouse conditions. To achieve this objective, different irrigation levels (IL) of IL100 (100% full irrigation), IL75 (75%), IL50 (50%), and vermicompost doses (VD) of VD0 (0%), VD10 (10%), and VD20 (20%) were tested. The highest irrigation level was in the IL100-VD10 treatment, which also had the highest water consumption (ET) in the 27.8 L pot-1. By comparison, the IL50-VD0 treatment had the lowest irrigation level in the 15.4 L pot-1, representing nearly 55.4% of the maximum irrigation water amount. The findings showed that the irrigation levels and vermicompost doses had a significant impact on plant growth, quality, and fruit yield parameters. Accordingly, the irrigation levels and vermicompost doses had significant effects on the studied plant growth parameters (stem diameter, plant height, number of leaves, stem fresh weight, stem dry weight, root fresh weight, and root dry weight). Similar effects were also observed on the fruit quality parameters (fruit width, fruit length, fruit weight, fruit flesh thickness, pH, titratable acidity (TA), total soluble solids (TSS), chrome, and hue). This study found that the highest total yield (164.5 g pot-1), marketable yield (149.8 g pot-1), total water use efficiency (6.1 g L-1), and marketable water use efficiency (5.6 g L-1) were obtained at the 100% irrigation level. However, similar results were observed at the 75% irrigation level and a 20% vermicompost dose, where the total water use efficiency was 5.9 g L-1 and the marketable water use efficiency was 5.3 g L-1. This suggests that 75% irrigation can be a viable alternative to full irrigation (100%) and offers water-saving potential, particularly in areas with limited water resources.

    THE EFFECTS OF HIGH TEMPERATURE AND LOW HUMIDITY ON CROP WATER STRESS INDEX OF SEED PUMPKIN PLANTS (Cucurbita pepo L.) IN SEMI-ARID CLIMATE CONDITIONS
    (Univ Life Sciences Lublin, 2024) Ucak, Ali Beyhan; Kociecka, Joanna; Liberacki, Daniel; Saltuk, Burak; Atilgan, Atilgan; Stachowski, Piotr; Rolbiecki, Roman
    This study aimed to evaluate the effects of high temperature and low humidity on the crop water stress index (CWSI) of seed pumpkin plants grown under semi -arid climate conditions to determine the optimum irrigation time. This research unveils the critical impact of high temperature and low humidity on seed pumpkin growth, emphasizing the vital role of the CWSI in optimizing irrigation strategies and seed yield. Moreover, the relationship between CWSI, physiological parameters, and seed yield of the pumpkin was investigated. The mean CWSI values in the I70 (0.40) and I35 (0.56) treatments were 42% and 100% higher, respectively than those in the full irrigation (I100) treatment (0.28). While the I70 treatment showed manageable water stress with minimal impact, the I35 treatment experienced severe stress, significantly reducing crop growth and yield. The mean seed yield (SY) in the I70 treatment increased to 1245.2 kg ha(-1) compared to I35 (903.3 kg ha(-1)) but remained lower than I100 (1339.3 kg ha(-1)). The CWSI had negative correlations (p <= 0.01) with seed yield, chlorophyll content, and leaf area index, while it had positive correlations with water use efficiency and irrigation water use efficiency (p <= 0.01). This study showed that pumpkins could be grown successfully at 30% water deficit conditions, and a water deficit higher than 30% may cause a significant seed yield loss in semi -arid climate conditions. In addition, the results highlight the importance of optimal irrigation and CWSI monitoring for informed irrigation decisions and sustainable agricultural practices. Therefore, moderate water deficit (I70) can be adopted in pumpkin cultivation as an alternative to full irrigation.

    The Importance of Rainwater Harvesting and Its Usage Possibilities: Antalya Example (Turkey)
    (Mdpi, 2023) Ertop, Hasan; Kociecka, Joanna; Atilgan, Atilgan; Liberacki, Daniel; Niemiec, Marcin; Rolbiecki, Roman
    The significance and effective use of water, one of the most basic requirements for sustaining vital activities, is gaining importance every day. Population growth and unprogrammed industrialization accelerate the consumption of available water resources. However, drought, as a result of climate change, poses a threat to water resources. Factors such as the exhaustibility of water resources, rapid population growth, unscheduled industrialization and drought increase the tendency towards alternative water resources. Rainwater harvesting is based on the principle of using the rainwater falling into the regions after it is stored. Water collected through rain harvesting can be utilized in many different areas, such as agricultural irrigation, landscape irrigation and domestic use. Among agricultural activities, the idea of water harvesting in greenhouse areas comes to the fore. Due to the gutters on the greenhouse roofs, water can be stored. In Antalya, which has about half of the greenhouses in Turkey, the amount of water in the rain harvest that can be obtained in greenhouses is 224,992,795.8 m(3) per year. Monthly calculations throughout the year showed that the minimum water can be harvested in August (938,447.53 m(3)) and the maximum (54,771,210 m(3)) in December. Therefore, it is thought that some plant water consumption can be met by building sufficient storage in areas close to the greenhouse.

    Use of Rainwater Harvesting from Roofs for Irrigation Purposes in Hydroponic Greenhouse Enterprises
    (Mdpi, 2024) Boyaci, Sedat; Atilgan, Atilgan; Kociecka, Joanna; Liberacki, Daniel; Rolbiecki, Roman
    This study was conducted to determine the irrigation water demand due to solar radiation in high-tech greenhouses using hydroponic systems in Turkey's Mediterranean and continental climates, and to determine the annual water consumption and storage capacity with harvested rainwater. Intensive greenhouse cultivation and the recent increase in modern greenhouse cultivation were important factors in selecting the provinces for the study. The chosen provinces were Antalya and Adana, with a Mediterranean climate, and Afyonkarahisar and K & imath;r & scedil;ehir, with a continental climate. In this research, depending on the production period, the amount of water consumed per unit of area in greenhouses in Antalya, which has a Mediterranean climate, was determined to be 1173.52 L m-2 per yr-1, and in Adana, it was 1109.18 L m-2 per yr-1. In the provinces of Afyonkarahisar and K & imath;r & scedil;ehir, where a continental climate prevails, water consumption was calculated to be 1479.11 L m-2 per yr-1 and 1370.77 L m-2 per yr-1, respectively. Storage volumes for the provinces of Antalya, Adana, Afyonkarahisar and K & imath;r & scedil;ehir were found to be 438.39 L m-2, 122.71 L m-2, 42.12 L m-2 and 43.65 L m-2, respectively. For the provinces of Antalya, Adana, Afyonkarahisar and K & imath;r & scedil;ehir, the rates of rainwater harvesting and meeting plants' water consumption were calculated to be 80.79%, 54.27%, 27.47% and 25.16%, respectively. In addition, the amount of water fee savings that could be achieved by rainwater harvesting was calculated to be USD 901.3 per yr-1 for Antalya, USD 835.3 per yr-1 for Adana, USD 247.6 per yr-1 for Afyonkarahisar and USD 210.2 per yr-1 for K & imath;r & scedil;ehir. As a result, rainwater harvesting will not only provide economic gain to enterprises but will also be important in reducing the negative effects of irregular rainfall regimes caused by climate change on underground and surface water resources. It was also concluded that enterprises should focus on popularizing rainwater harvesting.
