THE INFLUENCE OF SOIL AGRO-PHYSICAL PROPERTIES AND IRRIGATION REGIMES ON THE PRODUCTIVITY OF SUNFLOWER VARIETIES AND HYBRIDS GROWN AS A REPEATED CROP

Abstract

This scientific article examines the effect of soil agro-physical properties and irrigation regimes on the productivity of sunflower varieties and hybrids grown as a repeated crop. The research identified how different irrigation rates and timings influence plant growth stages, the efficiency of light and moisture utilization, and seed yield. It was also proven that the soil’s mechanical composition, density, and moisture capacity directly affect the biological characteristics of sunflower plants. The results of the study contribute to determining the optimal irrigation schedule and maintaining soil fertility when cultivating sunflower as a repeated crop.
