Özet
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.
