The experiment was made in the area of Szarvas (Hungary) in 2022-2023. The type of the soil was chernozem, slightly acidic and with a medium content of humus. The crop culture was early maturing maize (FAO 350). The weather throughout the year was very dry with low amount of rain so this reduced the yield. We separated irrigated, 2x and 4x irrigated parcels and used minimum and conventional tillage. The irrigated treatments were watered four times. During the Leaf Area Index measurement, we did not find any significant difference between tillage types, but between irrigations the research showed significant changes. Non-irrigated LAI data was around 1,05 m2/m2, in the irrigated parcel it was ~2,54 m2/m2. The same result could be obtained from the Soil Plant Analysis Development (SPAD). The lowest value was in the minimum tillage (unirrigated) parcel, 46,89. Anyway the highest value was in the minimum tillage (irrigated) parcel, 58,83. In the case of yield the maize reached maximum of 6,88 tonnes/hectare in irrigated treatments. Yields ranged from 3 to 4 t/ha in the parcels where we did not irrigate. Last but not least the soil resistance represented us that in the minimum-tillage parcels, the resistance was much higher in than the conventional tillage at the same depth. So, summarizing my measurements, I can conclude that irrigation has a positive effect on maize in many respects. From the comparison of the tillages, I concluded that there was no significant difference between minimum and conventional tillage in most cases. However, min-till is economically much reasonable than conventional tillage. Therefore, the use of minimum-tillage in maize cultivation is recommended.
