THE RELATIONSHIP BETWEEN THE CROP, NUTRITION PARAMETERS OF WINTER WHEAT AND THE VARIOUS DOSES OF FERTILASER TREATMENTS ANALISED BY ONE-WAY ANOVA

The winter wheat varieties in public cultivation differ in their response to the agrotechnical factors. It is especially true of their fertilizer reaction. Therefore, it is important to determine the natural nutrient-utilising ability and the fertilizer reaction of wheat varieties with different genetics. Being aware of these properties, we can increase fertilizer efficiency, reduce the load on the environment, and optimize sales revenue. Our experiment was carried out in Hungary, in a settlement called Hódmezovásárhely, on the territory of the University of Szeged Pilot Farm Ltd. The soil of the chosen area is meadow soil, with an adequate nitrogen supply, being poor in phosphorus, and good in potassium. During the experiment, besides the control (N0PK0), the following different dosage treatments were applied: Nitrosol, N80PK30, N100PK30, N120PK0, N120PK50, N130PK30 kg/ha. The variety in the experiment was Lucullus. Prior to the harvest, the plant height was measured, and we took plant samples from each parcel and determined some yield components and quality parameters. The results were evaluated by single-factor analysis of variance (one-way ANOVA). Our aim was to determine for yielding elements and quality parameters, whether there is significant difference between the means of each treatment-group, i.e. whether the treatment had a significant influence on the mean value of the given parameter. This way, we can get an answer if it is worth dealing with certain treatments for the given yield components and quality parameters.
