Abstract. The purpose. To study the effectiveness of a complex multicomponent organomineral fertilizer of prolonged action based on local man-made waste from the metallurgical industry and poultry farming and extracted sources of mineral nutrition for plants. Methods. The article presents data on the study of the effect of a new organomineral fertilizer on the growth, development and yield of spring barley. Phenological and biometric observations were carried out, yields were taken into account, and quality indicators of grain were determined: weight of 1000 seeds, nature and protein content. Results. It has been established that the use of an innovative mixed multicomponent organomineral fertilizer improves the growth and development of barley plants. So at doses of 60 and 90 kg of AD per 1 ha of nitrogen and phosphorus, the length of the plant stem increased to 6.78–6.84 cm, the number of grains per ear increased from 0.39 to 1.08 pcs. and their weight increased by 0.13–0.15 ha. The highest yield was obtained with NP (60) – 4.91 t/ha, which is significantly higher than the control variant. When applying the fertilizer, the grain quality indicators improved: the weight of 1000 seeds, the nature of the grain and the protein content in the grain. It is noted that the use of a new organomineral fertilizer at a dose of NP (60) increases the productivity and quality of products and is optimal for the cultivation of barley in the Middle Urals. Scientific novelty. For the first time in the Middle Urals, a new innovative product was created and tested – a combined, mixed multicomponent fertilizer for growing crops, application for a patent of the Russian Federation No. of the task number 122032200206-4.
