The influence of mineral fertilization upon production and quality of spring barley on agricultural research and development station Turda

In order to clarify some aspects of the spring barley reaction on the production and accumulation of the protein in grain, at different levels of fertilization, some estimates of this chemical component were made at 16 levels of fertilization with N: P: K in the period 2016-2017 . The increase in protein content was achieved at the highest levels of nitrogen and phosphorus, even when potassium fertilizers were not used, but the highest protein content in grain accumulating at the level of N60P80K0 was 11.78%. The highest yield can be attributed to the fertilization variant N120P80K40, which confirms the negative relationship between production and protein content.
