The present study aims to provide empirical evidence for assessing the economic and environmental feasibility of sustainable agronomic solutions, thereby seeking to contribute to the existing debate on the adaptation of Bulgarian agriculture to the goals of the Green Deal. It includes empirical evidence that sustainable practices not only increase yields and profitability, but also improve the resilience of production systems to climate and market fluctuations - a conclusion consistent with the results of international research ( Tilman and al.,2002; Costanza and al ., 1997). The development aims to analyze the effects of the implementation of three sustainable practices – drip irrigation, inter-row grassing and IPM – in a large agricultural farm with cherry and apple orchards in the village of Topolchane, Southeastern region of Bulgaria. The analysis covers the period 2022–2024, and is structured on an experimental design based on three regimes: control, single practice and integrated practices. The indicators used include yield, WUE, commercial calibration, costs, net value of production and sustainability index (CI). The data are supplemented by laboratory analyses of soil samples according to ISO 11272 and ISO 10390, as well as cost reports reflecting costs for labor, plant protection and water.
