Megjegyzések:	Winter wheat is one of the most important cereals in the world, an in Hungary. The reason of that could be some important features, like high level of ecological adaptability, and the high value of flour which is made of that, due to the carbohydrate and protein content in proper ratio for human consumption. Intensive plant nutrition is one of most important factors for increasing yields as well as it is a costly and energy demanding process. That is respectable while using chemical nutrients in right amount and form to be economical and ecological. In this work chlorophyll activity of winter wheat was measured by SPAD-502 PLUS instrument on different nitrogen doses. After analysis of soil samples, nitrogen content was evaluated as well, that determinate quantity and quality of yield. Experiments were set up in Hatvan-Nagygombos in the cropyear 2011-2014, whith the use of two different winter wheat variety (Mv Magdaléna and Mv Toborzó ). Different nitrogen doses were used in varied method of splitting of topdressing. On the basis of the results of experiments it can be stated that the doses of nitrogen applied have significant impact on the physiological state (SPAD value) and the quality (measured by NIR analyser) parameters of winter wheat Even low but positive correlation was found but it can be stated if SPAD value in early period in case of Magdaléna does not reach 50 or 45 in case of Toborzó than yield will be under 4 t/ha for Magdaléna and 5.5 t/ha for Toborzó.
