Abstract

Based on scientific research conducted during 2023–2025, this article analyzes the influence of planting dates and mineral fertilizer application rates on the daily stem growth dynamics (cm/day) of spring soft wheat varieties “Janub Gavhari” and “Parvoz”. The findings demonstrate that the period of most intensive plant growth occurs during the “tillering-to-booting” and “booting-to-heading” phenological stages. Furthermore, optimal mineral fertilizer rates, specifically N210P90K60, and an optimal sowing date (the third decade of March) significantly enhance stem growth rates.
