The article presents the results of a comprehensive study on the impact of various fertilization systems on the growth, development, and biomass accumulation of grain sorghum (Sorghum bicolor L.). The author examines the interaction between mineral fertilizers (NPK) and modern biological preparations (inoculants and growth biostimulants) across different maturity groups, ranging from early-maturing to late-maturing varieties. The research evaluates how the synergy of biological and mineral nutrition influences key parameters of biological productivity, including plant height, leaf area index, and dry matter distribution. It was established that early-maturing varieties show a higher responsiveness to biological starters, while late-maturing genotypes utilize mineral fertilizers more efficiently due to their longer vegetation period. The findings substantiate that an integrated fertilization approach significantly enhances the grain yield and energy value of sorghum, providing a sustainable solution for grain production in arid and semi-arid conditions.
