The effectiveness of a new organomineral fertilizer in potato cultivation in the Middle Urals

Purpose of research. To study the effectiveness of a complex multicomponent organomineral fertilizer of prolonged action on potato productivity. Method. The object of research is potato. The subject of research is to study the effect of a new combined organomineral fertilizer on the growth, development, and yield of potato. The studies were conducted in the field experiment in accordance with the basic requirements for their conduct according to B.A. Dospekhov. The experimental work is based on the following methodological recommendations: Methods of state variety testing of agricultural crops; Methods of field and vegetation experiments with fertilizers and herbicides. Results: An innovative product has been developed – a mixed combined organomineral fertilizer based on natural extracted mineral raw materials, bird droppings, and waste from the coke industry. The chemical composition of the fertilizer contains 6 macronutrients of plant nutrition: nitrogen (N) 12%, phosphorus (P2O5) – 12%, potassium (K2O) – 2%, sulfur (S) – 10%, calcium (Ca) - 36%, and silicon (Si) – 25%. The positive effect of fertilizers on the growth, development, yield, and quality of potato has been established. Potato yield at a dose of NP(90) and NP(120) is 5.5; 5.9 t/ha or 30; 32.2% higher compared to the control. It has been established that it is economically feasible to use NP(90) for potato, which ensures low cost and increases the profitability of the production of this crop with high product quality. 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 potatoes, application for RF patent No. 2023100288 (incoming number 0005490) dated 09.01.2023.
