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...
Field studies were carried out to test the impact of nitrogen fertilizers, nitrogen dose and mineral nitrogen content in soil before maize sowing on the initial growth of maize, nitrogen content, nitrogen assimilation and on the efficiency of the ingredient in maize grown in juvenile phase. There was presented that in the juvenile maize (BBCH 15/16) phase, the calcium nitrate was the worst among the...
Field studies were carried out in the Didactic and Experimental Farm in Swadzim near Poznań in the years 2004-2007. The objective of the studies was the investigation of the reaction of two types of maize cultivars to zero mineral fertilization and in consequence to the energetic value of the maize raw material grown on CCM in comparison with mineral fertilization. In the experimental studies, a more...
Doświadczenia polowe przeprowadzono w latach 1999-2001 w Uniwersytecie Przyrodniczym w Poznaniu badając plonowanie kukurydzy cukrowej w warunkach zerowego nawożenia azotem. Stwierdzono, że zwiększenie dawki azotu z 30 do 60 kg N ha-1 powoduje zwiększenie plonu kolb, wzrost udziału procentowego kolb I klasy oraz wzrost długości kolb i liczby ziaren w kolbie. Najwyższy plon kolb uzyskano po zastosowaniu...
