The limiting factor of yield is often the insufficient supply of plants with nutrients during the growing season. In this regard, it is necessary to find new techniques that provide a solution to this problem. The article presents the results of studies of micro-fertilizers on the yield and quality of white lupine grain. The use of Aquamix ST fertilizers and potassium Metaborate contributed to an increase in the yield of white lupine grain by an average of 37.5 and 35.4%. In all variants of applying Aquamix ST, an increase in the protein content in the white lupine grain of the Pilgrim variety was found. The excess over the control varied from 5.0 to 5.8 %. The use of Aquamix ST and potassium Metaborate on vegetative plants reduced the alkaloid content of lupin grain by 24.7 … 34.6%. Treatment of white lupine crops in the budding phase with Aquamix ST and potassium Metaborate increased the carotene content in the grain by 34.3 - 25.0%, respectively. The analysis of the data showed that the maximum amount of lysine and carotene was characterized by a variant that includes pre-sowing treatment of seeds with Aquamix ST and subsequent treatment of vegetating plants in the budding phase. On average, over the years of research, the use of micro and macro fertilizers led to an increase in feed units and digestible protein with the yield of lupine grain. More valuable in terms of feed were the options that combine high yield with high grain quality. The greatest collection of digestible protein of 1.26 t/ha, feed units of 6.0 t/ha and exchange energy of 54.8 GJ/ha was provided by Aquamix ST in the variant with pre-sowing seed treatment and two treatments for vegetation. Potassium metaborate, used for the treatment of vegetative plants in the budding phase, showed almost the same results.
