Summary

A pot experiment has been made with oats fertilized with increasing amounts of calcium nitrate, phosphorus, and various combinations of these. The yield of dry matter and the content of phosphorus, potassium, total nitrogen, soluble nitrogen, peptide nitrogen, and nitrate nitrogen were determined on three separate occasions during the growing period.

The number of tillers was increased to a certain extent by nitrogen and then decreased again with further applications. Phosphorus alone had no influence, but a positive interaction between phosphorus and nitrogen on the number of tillers was observed. Nitrogen increased the number of seeds per spikelet and the percentage of grain.

Except at maturity the content of potassium followed the content of total nitrogen, the percentage of which increased with increasing nitrogen supply. The content of nitrate nitrogen decreased during the growing period and at maturity was decreased by increasing phosphorus supply.

As a percentage of the total nitrogen, the peptide nitrogen and soluble non-nitrate nitrogen in the straw decreased with increasing nitrogen supply. Peptide nitrogen increased at maturity. When the phosphorus was added with a heavy dressing of calcium nitrate, the percentage and the yield of protein nitrogen seemed to increase.
