In this paper the researches performed in the period 1972-1995 are presented. The trials were performed on the chernozem soil type (Rimski Sancevi locality, Yugoslavia), well supplied with P and K. Kernel protein was correlated with various climate factors in order to establish critical moments during vegetative period for the kernel protein content level. It was proved that it was the wheat spiking period till the beginning of kernel ripening. The increase of the temperature sum in that period led to the decrease of the protein content no matter the level of nitrogen nutrition. Nitrogen taken from feeding provided higher protein content level, so in the case of extremely unfavourable temperatures, the quality of wheat remained at acceptable levels. However, there remained one practical problem - how to optimise nitrogen nutrition from the aspect of protein content, and yet to preserve kernel yield level.
