Abstract
The effect of nutrient supplies on the crude protein content and amino acid composition of naked oats was examined on chernozem meadow soil at 4×4×4 N, P and K levels. The crude protein content of naked oats increased over an NO3-N range of 124–179 kg ha”1 in the 0–60 cm soil layer. Over-fertilisation with N led to a reduction in the crude protein yield. Better N supplies caused an increase in the quantity of certain amino acids, to an extent differing in each experimental year. The amino acid composition of the protein was not influenced to any great extent by the N supplies. The crude protein content and crude protein yield exhibited little change over a soil P supply range of 120–360 mg kg””1 AL-P2O5, but considerable changes were observed in the quantity of amino acids and in the amino acid composition of the protein. The water supplies in the various years influenced both the protein content and the amino acid composition.
