Abstract: Due to ongoing climate change, the need for the application of adaptive strategies in agriculture is increasing, particularly in areas with insufficient rainfall, high temperatures and weather fluctuations during the vegetation period. Therefore, an experiment was conducted in 2020 and 2021 to determine the influence of superabsorbent polymers (SAPs) on morphological, physiological and production traits of maize. SAPs were applied using a method of seed coating, which is considered cost-effective and environmentally friendly. Due to the impact of SAPs, significantly larger weights of leaves and roots, as well as the length of roots in the initial growth stage, were found. Furthermore, the SAP treatment condition found significantly larger values of leaf relative water content and spectral indexes PRI (photochemical reflectance index) and NDVI (normalised difference vegetation index). Applying SAPs also led to a significant increase in spikes per plot and grain yield of maize. Moreover, the results significantly impact the interaction between year and treatment. The correlation analysis indicates a higher correlation between the observed traits in the SAPs treatment condition, which subsequently impacted the final maize production. These results confirm that applying SAPs can be considered a suitable strategy for mitigating the impacts of adverse weather conditions, especially in terms of sustainability and maintaining maize production.
