Investigations about the effect of ammonium‐ and nitrate nutrition on the formation of yield and protein of oats genotypes The formation of yield and proteins of three different oats genotypes (cv. Gambo, Flämingskrone, Caesar ) in dependence on ammonium or nitrate nutrition was investigated in pot trials over 2 years (from 1982 to 1983). On oats the NH 4 ‐nutrition showed in comparison to NO 3 nutrition increases in grain yield up to 20 % due to a favourable influence on the number of panicles per pot (s. Fig. 1). Protein content and protein yield increased particularly by high fertilizing with NH 4 ‐N (N 3 ‐ and Invariant); the best effect was ascertained by the N 4 ‐variant increase of 4 % (D.M.). Among the protein fractions (albumins, globulins, prolamins, glutelins) the albumin‐ and prolamin‐proteins increased after NH 4 ‐fertilizing by 1–2 %, whereas at the same time the glutelins decreased by 1–4 %; the globulins showed no differences.
