Urban agriculture refers to the practice of cultivating plants within city environments. It faces challenges such as accessing resources, soil, water, and air quality in urban environment. Field experiments were carried out in 2023 on alluvial-meadow soil located in Sofia city, focusing on growing cabbage and kohlrabi. Biometric analysis, absolute dry matter, and crop yields were conducted for both crops. Soil analyses were performed at the beginning of the experiment. The soil showed weak humus content, ranging 1.5% to 1.82%. The data obtained for kohlrabi yields and total available water, along with the correlation coefficient R2-0.77, indicate that an increase in irrigation rate results in decreased yield. Yields obtained in urban conditions ranged between 14-15 t/ha for kohlrabi and 34-47 t/ha for cabbage.
