Correlation between Leaf Area Formation and Net Photosynthetic Productivity in Soybean Varieties Under the Agroecological Conditions of Uzbekistan

Kizi, Khodiyeva Sitora Shokhabbos
ISSN 2997-7185 Vol. 3 · No. 10 DOI
Abstract. Net photosynthetic productivity (NPP) is an important physiological indicator that characterizes the efficiency of plant photosynthesis and reflects the amount of dry matter accumulated by a plant per unit of leaf area during a specific period. It is closely associated with the intensity …
