The research defined the effectiveness of corn fertilisation with nitrogen depending on its content in soil and covered N uptake, agronomical and physiological fertilisation efficiency as well as coefficients of nitrogen-fertliser utilisation. Spring and autumn doses were defined which were applied to balance N fertilisation and uptake by plants as well as the degree of N utilisation from the same doses applied in autumn and spring. As for the plant dry matter yield, the agronomical and physiological efficiency of all the spring N doses at 160 and 240 kg×ha-1 introduced into the soil in autumn were negative, and the coefficient of nitrogen utilisation against other fertilisers did not exceed 7.4%.
