Zinc-based agronomic bio-fortification strategies for soybean in the North Eastern Himalayas of India.

ABSTRACT: Zinc (Zn) deficiency is an emerging health issue in the North-Eastern (NE) Himalayas of India. Agronomic bio-fortification of soybean offers a promising solution as it is widely consumed throughout the NE regions. Therefore, this study aimed to assess the response of soybean varieties to different Zn sources and methods in terms of Zn bio-fortification, and bio-availability. The results revealed that, the soybean variety JS-97-52 recorded greater seed (1.67-1.87 Mg ha⁻¹ and stover yields (1.77-1.90 Mg ha⁻¹; however, the JS-335 had higher Zn content (31-31.5 mg kg⁻¹, lower phytic acid (PA) levels (569 and 585 mg 100 g⁻¹), and a lower PA: Zn ratio (18.2 and 18.9). Among Zn fertilization methods, the combined soil + foliar spray of ZnSO₄·7 H₂O (SA + FA-ZS) sig
