The use of maize, both as main and by-product, is extremely versatile and diverse. The
highest amount of carbohydrate within maize is found in the form of starch (C6H10O5)x. In terms
of industrial starch, maize is the most important raw material. Fodder maize is primarily an energy
source due to its high starch content, and its protein and oil content are less important. It was
found that starch and protein content, which are negatively correlated with each other, are
significantly affected by fertilizer doses. The experiment is located in the Hajdúság Loess Plateau,
its soil is loess-based deep humus layered calcareous chernozem. The following treatments were
applied in the scope of the polyfactorial experiment: Tillage: T1 = winter ploughing, T2 = strip
tillage, T3 = ripping. Crop years: 2017, 2018 and 2019. Fertilization treatments: N 0 kg ha-1 P2O5
0 kg ha-1 K2O 0 kg ha-1 (control); N 80kg ha-1 P2O5 60 kg ha-1 K2O 90 kg ha-1 and N 160 kg ha-1
P2O5 60 kg ha-1 K2O 90 kg ha-1. Analysis of the nutritional component was carried out by means
of a Foss Infratec TM 1241 Grain Analyser.
In terms of fertilization treatments, the highest (64.42%) maize starch content was measured for the
control treatment, while the lowest starch content was recorded in the case of the 160 kg N ha-1
treatment (62.62%). The analysis of the crop year effect showed that 2018 was the most
favourable year for the maize starch content of the examined samples (65.76%). Of the studied
years, the lowest starch content was measured in 2017 (61.78%).
