The study was conducted in the period 2022-2024 in the experimental field for organic farming of the Agroecological Center at the Agricultural University, Bulgaria. The yield of fresh and dry mass of saffron crocus (Crocus sativus L.) grown under organic farming conditions was studied. To achieve the goal, a field experiment was set up, with a two-row planting scheme in three repetitions and a rate of 32 plants/m2. Italpollina organic fertilizer was used for soil fertilization before planting. The harvesting and processing of saffron flowers was carried out manually, and the drying of the fresh mass was under controlled conditions with a temperature of 40°C for 3 hours. Meteorological conditions, including the amount of precipitation, influence the beginning of the vegetation of plants, the onset and duration of the flowering phase. The indicators of the beginning of flowering, number of flowers, yield and percentage ratio of fresh and dry mass (saffron) under organic cultivation conditions in Central Southern Bulgaria were studied.
