Wheat is one of the traditional crops grown by Ukrainian farmers. It is important to take the nutrition of spring wheat seriously, as it is more sensitive to the lack of moisture and nutrient content in readily available form. In Ukraine lately, spring wheat is hardly grown. In general, its cultivation can be described as an amateur business, although the soil and climatic conditions of the eastern and southern regions of Ukraine allow to obtain high quality grain. Determination of the influence of abiotic factors, namely the introduction of biological preparations of Bionorm Nitrogen and Bionorm Phosphorus (manufacturer: GC BioNorma, Ukraine), on the yield indicators and grain quality of durum spring wheat was the main purpose of this work. The studies were conducted at the research field of the Institute of Agrobiology, located in Vinnytsia region. Two varieties of spring durum wheat were selected, namely Isolde and Heritage. Analyzing the results of studies of the effect of biological products on the yield and quality of durum wheat grain, we can conclude that the best indicators (yield, nature, vitreousness, protein content and gluten) were recorded as a result of the use of a combination of two drugs: Bionorm Nitrogen and Bionorm Phosphorus
