Abstract: The yield, total and protein nitrogen content as well as proteins in paddy and white rice grain have been observed under influence of direct and prolonged activity of mineral fertilizers. Namely, in a stationary field trial by the "Cade" method on an alluvial soil, precrop rice, direct and prolonged activity of four quantities nitrogen and two quantities phosphorus and potassium fertilizer were investigated in rice variety Monticelli (3 years of application and 1 year of application, 2 years prolonged activity). The variants in the trials were the following: Control - untreated; I-N45P45K45, II - N90P90K90, III - N120P90K90 and IV - N150P90K90. The fertilizers (NPK 15:15:15 and Uras 27%) were applied pre-plant. Results obtained from the investigations show that there were no significant differences in the content of fractions during the paddy whitening between the variants - direct activity and the variants - prolonged activity of the mineral fertilizers, as well as in the various years of investigation. The best average white rice yield (whole grains) is achieved in the variant I-N45P45K45 (both in direct fertilizer activity and prolonged activity). The total nitrogen, protein, and paddy and white rice protein content vary in various years of investigations as well as in the investigated variants themselves. The highest total nitrogen, protein nitrogen and protein content is obtained in the trial year.
