Influence of Mineral Fertilizers on the Quality of Raw Materials of <i>Nigella sativa</i> L. in Uzbekistan

The article is devoted to the study of N. sativa cultivation using mineral fertilizers to increase the yield of medicinal plants and improve their chemical composition. Research shows that with the correct use of essential nutrients such as nitrogen, phosphorus and potassium, plant growth processes are accelerated, and the amount of biologically active substances such as thymoquinone and alkaloids increases significantly. As a result, the medicinal properties of N. sativa are enhanced. The correct choice of mineral fertilizer balance and the use of optimal agrotechnical methods increase the possibility of obtaining high-quality and environmentally friendly medicinal raw materials in agriculture.
