Abstract
The success of sweet maize cultivation is affected by a number of environmental and technological factors. In addition to choosing the appropriate genotypes to cope with stress effects, it is important to use precision farming techniques, nutrient supply and irrigation adapted to the genotype. Sweet maize is one of the most drought-sensitive crops in arable farming, therefore, the use of precision irrigation farming techniques is essential for successful management. Our experiments were carried out under controlled conditions in three different crop years (2020, 2021, 2022). In June and July, irrigation was carried out with drip irrigation. The raw grain weight per hectare of the GSS sweet maize hybrid differed significantly from year to year. In the unfavourable year 2022, the raw grain yield was 10.400 t/ha. In contrast, in 2021 and 2020, the grain yield was significantly higher, at 1.466 and 2.810 tonnes per hectare, respectively. We measured close, consistent relationships between rainfall and irrigation volume when analysing the combined water use. For 1 mm of water (from precipitation and irrigation), we measured 27.1 kg of grain weight in 2020; 25.6 kg in 2021; and 23.5 kg in the unfavourable growing year 2022.
