THE EFFECTS OF AGRONOMIC FACTORS ON THE ECONOMIC EFFICIENCY OF BLACK CUMIN PRODUCTION
Background. Black cumin (Nigella sativa L.) known for its health benefits, can be grown under various production technologies associated with different production costs. Therefore, the aim of this study was to determine the economic profitability of black cumin cultivation under different agronomic conditions in north-eastern Europe.
Material and methods. The experiment had a fractional factorial and completely randomized design,with four replications. Nigella sativa L. was grown in integrated farming system during a two-year field experiment. The analysis of economic effectiveness was calculated according to agricultural accounting standards.
Results. The highest income of 627.10 USD·ha-1 was achieved in the treatment involving mechanical weed control. The highest profitability index was noted in treatments with seed dressing and no pathogen control during the growing season, and with mechanical weed control (1.46 and 1.56, respectively).
Conclusion. The agronomic efficiency of black cumin was low. The most profitable production system involved the latest seeding date, inter-row spacing of 30 cm and mechanical weed control. Total costs ranged from 1077.32 to 1177.32 USD·ha-1.
