Dynamics of SPAD Index, Leaf Pigment, and Macronutrient Relationships in Sugar Beet Leaves Under Spring Nitrogen Fertilization

Nitrogen, Journal Year: 2025, Volume and Issue: 6(1), P. 10 - 10

Published: Feb. 18, 2025

Nitrogen fertilization greatly affects the development of sugar beet leaf and photosynthetic activity. This study aimed to evaluate dynamics SPAD index, chlorophyll a (Chl a), b b), carotenoids (Caro), macronutrient status (N, P, K, Na, Mg) in different N rates production. set up two-year field experiment Eastern Croatia. The rate was applied as: N0—control, N1—only presowing (45 kg/ha), N2—presowing with topdressing (99 kg/ha 2014 85.5 2015). In general, has significant (p ≤ 0.05) influence on pigments, except for Chl b. With highest dose (N2), content leaves increased by 12% compared control treatment (0.75 mg/g FW). Caro vegetative growth were significantly 0.05); younger stage at end May had (0.011 index 0.05), among fertilization, whereas lowest found (38.7) N2 (40.8). regarding nitrogen readings (38.7), determined A strong positive relationship 0.01) a, b, + b/Caro an inverse a/b. results demonstrate that application, particularly higher rates, positively influences carotenoid content, as well overall plant health, which can inform agricultural practices more sustainable efficient cultivation.
