MINERAL NUTRITION AND POTENTIAL PRODUCTIVITY OF MISCANTHUS SACCHARIFLORUS

The application of mineral fertilizers did not significantly affect the yield of Miscanthus. There is a trend towards its increase. The absence of significant differences in the nitrogen content in biomass between the options (NSR05 = 0.09) - 0.2-0.4 % at the end of the growing season was noted. The K content varied from 3.1 -3.7 % at the beginning of the growing season to 0.3% by the end of the growing season for all experimental variants. The variation in P during the growing season of the crop was weak - from 0.3-0.4 % in June to 0.1% in September. The optimal option with good productivity (11.2-14.0 t/ha) and minimum costs for feeding the grass stand is option N30.
