Soil-Specific Effects of the Bio-Growth Regulator Supporter on Seed Potato Yield and Quality Across Varieties: Unlocking Sustainable Potential in Diverse Environments

The growing demand for sustainable agricultural practices requires the search for innovative solutions to improve crop yield and quality. This study investigated the soil-specific effects of the bio-growth regulator Supporter on seed potato yield and quality in different potato varieties, with the aim of unlocking its sustainable potential under different environmental conditions. Field trials were conducted on several soil types using the bio-growth stimulator Supporter at a rate of 300 mL per hectare. Standardized agronomic practices, including continuous fertilization, weed control, and pest control, were applied at all test sites to ensure comparability. The results showed that the use of the bio-growth stimulator Supporter significantly increased tuber yield and quality, especially in soils with moderate fertility levels. In the treatments, with the Supporter biostimulator, there was better tuber size uniformity and a higher fraction and number of seed potato. A higher average seed potato mass and higher multiplication coefficient were observed. The effectiveness of the Supporter varied across study locations and soil types, with sandy and sandy loam soils showing the most pronounced benefits, while clay soils showed more limited responses. The results underscore the potential of the Supporter as a sustainable tool for increasing potato seed production, while also emphasizing the need for soil-specific recommendations. This study highlights the importance of integrating growth regulators into precision agriculture to optimize crop performance and support global food security goals. Therefore, further research is needed on the use of biostimulants, which will allow us to understand the purpose of their action, which is important in agricultural practice.
