Effects of nitrogen and sulphur fertilisers on the yield, N and S content, and amino acid composition of the grain of spring wheat

Solubility characteristics and amino acid composition of the endosperm proteins of one line of Triticale, its durum wheat and rye parent cultivars, and one cultivar of hard red spring wheat were compared. Quantitative distribution of the soluble protein fractions and amino acid compositions showed that the proteins of Triticale are intermediate in these properties between analogous properties of the proteins of its durum wheat and rye parents. The major differences between the hard red spring wheat and the other three species were its lower content of water-soluble proteins and higher content of insoluble or gluten proteins. This appears lo be the main reason for the superior breadmaking quality of the hard red spring wheat cultivar compared with the other species used in this study.

Nitrogen Fractions

Grain from hard red spring wheat (Triticum aestivum ’Neepawa’) grown with nine rates of N fertilizer (0–400 kg/ha) was analyzed for total N, non-protein N (NPN), and amino acids. In addition, the amino acid compositions of the various soluble protein fractions were determined. The percentages of total N, NPN, and protein N of the grain increased with each 50-kg increment of N up to the 150-kg rate. The proportions of glutamate, proline, and phenylalanine in the seed increased whereas threonine, serine, glycine, alanine, and valine decreased with the first three or four increments of N fertilizer. With increasing N content in the seed, the proportions of albumin, globulin, and glutenin 2 decreased while the proportions of gliadin and glutenin 1 increased. The various protein fractions differed from each other in amino acid composition but the amino acid composition of each fraction was not influenced significantly by N application.

Wheat Protein

Sprinkler irrigation on clay soils in southern Finland decreased the protein content of spring wheat flour in five field experiments in the years 1967—70, by 16 ± 4 per cent on an average. The amino acid composition, however, was improved, because the proportion of lysine was increased by 6 ± 4 %. Accordingly, the content of lysine in flour was decreased by irrigation only by 10 ± 5 %. An increase of fertilizer nitrogen from 68 to 144 kg/ha increased the protein content of wheat flour by 19 ± 5 %, but the proportion of lysine in the amino acid composition decreased by 9 ± 4 %. Therefore, the lysine content in flour was increased by nitrogen fertilization only by 8 ± 5 %. It seemed as if urea and ammonium nitrate limestone would have had about the same effect on the quantity and quality of wheat protein. As a consequence of the reversed influences of irrigation and nitrogen fertilization on the wheat protein it was possible, by means of irrigation and an additional nitrogen fertilization, to produce 65 per cent higher grain yields without any noteworthy changes in the contents of protein or amino acids.

Control Variant

The paper presents the results of applying nitrogen fertilizers for spring wheat of the Novosibirsk 31 variety. The use of the fertilizers produced additional 1,62 t/ha of grain relative to the control variant. The maximum yield was 5,4 t/ha. The increased doses of the mineral fertilizers resulted in the increased ammonium ion in the grain, the rate reached 0,76 %. The excess of ammonium ion in spring wheat is neutralized by glutamine in the composition; the glutamine content reached 5,4 %. At the same time, the synthesis of arginine was reduced from 5,1 to 1,0 %.
