Abstract

The article investigates the effect of nitrogen (N), phosphorus (P), and potassium (K) application rates on physiological processes and water regime parameters in rice (Oryza sativa L.) varieties. The experiments determined the content of chlorophyll “a” and “b” in leaves, photosynthetic intensity, leaf water potential, transpiration rate, and relative water retention. The results showed that increasing macronutrient rates enhanced photosynthetic activity and leaf water content, while certain changes in transpiration processes were observed. Balanced NPK application was found to improve water use efficiency and ensure physiological stability of rice plants.
