Abstract

The effect of different N, P and K levels and their combinations on the aboveground yield, mineral composition and powdery mildew resistance of wheat and on the amino acid content of the grain yield was studied in a fertilisation experiment set up in autumn 1973 on a calcarcous loamy chernozem soil. After harvesting the following data were recorded: the available nutrient content of the soil, the ion concentration in a 1:5 aqueous extract, and changes in the "total salt" reserves in the ploughed layer and in soil profiles taken from the treatments studied. The agrochemical parameters of the ploughed layer were as follows: CaCO3 5%, humus 3%, pH(KCl) 7.3, AL-P2O5 60-80 ppm, AL-K2O 140-160 ppm, KCl-soluble Mg 150-180 ppm, KCl + EDTA Mn 80-150 ppm, Cu 2-3 ppm, Zn 1-2 ppm. The experiment consisted of 4N×4P×4K=64 treatments each in two replications, making a total of 128 plots. The fertilisers were applied in the form of 25 % calcium ammonium nitrate, 18% superphosphate and 50% potassium chloride. The results achieved for grain yield, plant composition and specific nutrient requirements can be summarised as follows: 1. After 4 years of alfalfa a substantial increase in wheat grain yield was achieved through P fertilisation, due to the poor P supplies of the soil. The moderate yield-increasing effect of K fertilisation (0.5-0.6 t/ha) was attributed to the improved powdery mildew resistance of the wheat. 2. The mineral composition of the wheat reflected the soil supply levels. The greatest differences were observed in young shoots and in the straw yield, which exhibited luxury uptake. N fertilisation only increased the plant N% on soils satisfactorily supplied with P; there was a pronounced N×P interaction. A N×K interaction was observed in the uptake of K. There was significant K/Mg, P/Zn and, to a lesser extent, P/Fc antagonism, and P/Mn synergism. 3. The specific nutrient requirements of 1 t grain plus the by-products at harvesting were 25-30 kg N, 16 kg K2O and 12 kg P22O5. Ca, Fc and Mn accumulated chiefly in the straw and Mg, Zn and Cu in the grain. The specific requirements were 4-5 kg Ca, 3 kg Mg, 220 g Fc, 120 g Mn, 31 g Zn and 14 g Cu. These data could serve as the basis for extension service recommendations.
