ABSTRACT
The paper presents the results of field tests whose aim was to assess the effect of mineral (nitrogen) fertilization on the chemical composition of green fodder and milk production. The purpose of verification of the adopted assumptions was to determine the chemical composition of green fodder, the content of green fodder fraction, nutrient value of green fodder, green and dry matter of maize, the cost of maize silage production and milk production volume. Mineral fertilization has been shown to have a very large influence on the yield of the silage material. Fodder derived from maize fertilized is characterized by a higher concentration of total protein and starch in comparison to non-fertilized plants. In addition, fertilized maize plants are characterized by a higher energy and protein value in feeding cattle in relation to non-fertilized plants. From one ha of nitrogen fertilized maize cultivation it can be produced 5 309 kg of milk more than from non-fertilized cultivation.
