Quantitative indicators of the medicinal herbs growth and yield on an experimental plantation in northern kazakhstan

Climate change, man-made and anthropogenic factors have negatively affected the flora, therefore, the reserves of wild-growing grasses in nature are sharply reduced. For this reason, the mass cultivation of medicinal herbs on plantations is becoming an important task. Aim of research – development of an environmentally friendly and rational technology for growing medicinal herbs on plantations in the northern region of Kazakhstan. Materials and methods. The research was carried out in the Akmola region, the following species of medicinal herbs were selected as the objects of research: Echinacea purpurea Moench, Salvia officinalis, Origani vulgaris, Népeta catária, Adónis aestivális, Ínula helénium, Thymus serpyllum. Nitrogen fertilizers were used for the growth of the medicinal herbs, while the soils on the control plots did not contain any fertilizers. Results. It was found that the use of fertilizers increased the number of seedlings in all studied plants by 6.3 – 62.8% compared to the control. The increase in plant’s growth, development and height was observed in Breckland thyme, catnip, and summer Adonis. The rest of the medicinal herbs growth and height were smaller than that of the control. The crop yield of catnip, oregano, sage, Breckland thyme and summer Adonis in the experimental plot was higher by 1.7-35.8 than that of the control. It has been determined that purple coneflower and elfdock are best grown without addition of plant growth substances. Conclusion. The application of fertilizers to the soil has a positive effect on the growth of the studied species of medicinal plants, except for purple coneflower and elfdock.
