EFFECT OF AGROTECHNICAL FACTORS ON THE GROWTH, DEVELOPMENT AND PRODUCTIVITY OF BLACK CUMIN (NIGELLA SATIVA L.) (IN THE CONDITIONS OF NUKUS).

Under the salinized soil conditions of the Republic of Karakalpakstan, research was carried out in Nukus during 2022–2024 to develop an improved cultivation technology for Black Cumin (Nigella sativa L.). The study investigated the effects of major agrotechnical factors - including sowing date, planting arrangement (row and plant spacing), and seed rate - on the plant’s growth dynamics, developmental phases, and seed yield performance. Based on the results of the study, the optimal conditions for maximizing seed yield were determined to involve sowing during the second ten-day period of April (approximately April 12), adopting a planting configuration of 45 cm row spacing and 15 cm intra-row spacing, and applying a seed rate of 10 kg per hectare. This combination of agronomic parameters proved to be the most effective in ensuring the highest seed productivity. The findings generated in this study provide scientifically grounded and practically applicable recommendations that can significantly enhance the efficiency of Black Cumin (Nigella sativa L.) cultivation under the specific agro-environmental conditions of the Nukus region.
