Abstract: Climate changes and competition between agriculture and oth­er sectors for soil and water resources usage that water resource manage­ment obtains increasing significance. As a part of agricultural water re­source management the choice of irrigation scheduling method influences the yield, water and fertilizer use efficiency, energy consumption, cost-effec­tiveness, etc. This paper focuses on the comparative analysis between evap­otranspiration-based and tensiometer-based irrigation scheduling com­ponents and cost-effectiveness. Using data from a greenhouse experiment carried out with first-year strawberry plants (Fragaria x ananassa “Snow White”) in 2023 at the experimental field of Chelopechene at the Institute of Soil Science, Agrotechnologies and Plant Protection “Nikola Pushkarov”, Sofia, Bulgaria. The results show that evapotranspiration-based irrigation scheduling is more cost-effective than tensiometer-based one.
