Abstract
In investigations on amino acids of silo-maize, different nitrogen fertilizers were studied to determine their effect on amino acid composition and variation during the growth period. The experiment was carried out with silo-maize, hybrid W 464A, grown on sandy soil, which had not been treated for six years with either fertilizers or manure. Before cultivation phosphorus and potassium fertilizers were applied, and the nitrogen fertilizers, ammonium sulphate, ammonium nitrate, calcium cyanamide and urea, were applied at the most appropriate time of application. The first samples were taken at the time of flowering, the second after flowering, and the third, fourth and fifth in the lactic, wax, and full maturity phases, respectively. The percentages of crude protein of the maize gradually decreased while the nitrogen-free extraction matter increased during this period. The protein content of the maize was highest with sodium nitrate and urea fertilization and lowest when calcium cyanamide was used. Investigations to determine whether or not an increase in crude protein content was correlated with an increased content of lysine have shown that there is a correlation when plants are fertilized with calcium cyanamide. The content of essential amino acids was more satisfactory in plants fertilized with urea than
