Field experiments were conducted on Shajiang (with concretions) black soils with low or medium fertility in southern Henan in 1984-86 to evaluate the influence of N, P and organic manure on quality of winter wheat. Protein, protein N, lysine and gluten contents and precipitation value of the wheat seeds were positively correlated with the amount of N applied in addition to basal P and organic manures.
