| Abstract | Goal. To determine the influence of different methods of mineral fertilizer application (broadcast and localized) in various doses on the yield and oil content of spring camelina under the conditions of the Right-Bank Forest-Steppe of Ukraine. Methods. Field experiments, laboratory measurements, comparative analysis, statistical processing. The results. The study revealed that the localized application of mineral fertilizers significantly increases the yield of spring camelina compared to broadcast application. In 2023, under less favorable weather conditions, the highest yield (1.89 t/ha) was achieved with localized application of N60P60K60, which exceeded the control by 0.79 t/ha. In 2024, with more favorable conditions, the yield reached 2.12 t/ha. Lowering the dose to N30P30K30 reduced the yield slightly (1.85 t/ha), indicating efficient use of nutrients. Broadcast application resulted in 10–15% lower yields in both years. The oil content of camelina seeds was relatively stable and ranged from 37.8 to 40.1%, with minor differences between treatments. The highest oil content was observed with localized N60P60K60 application. Conclusions. Localized fertilizer application ensures the highest yield of spring camelina while maintaining stable oil content. Reducing fertilizer doses is economically and environmentally viable when localized application is used. Spring camelina is a promising crop for sustainable and efficient fertilization systems. Reducing the nitrogen dose under localized application helps maintain a high oil content (41.5%), which is an important indicator of seed quality. The environmental effectiveness of localized fertilizer application lies in reducing the risk of nutrient loss, improving fertilizer use efficiency, and minimizing negative environmental impacts. The obtained results are consistent with the findings of domestic researchers and confirm the feasibility of using localized fertilizer application in spring camelina cultivation under the conditions of the Right-Bank Forest-Steppe of Ukraine. | ||
