Zinc (Zn) and Boron (B) are micronutrients required by plants in small amounts but play an important role in plant growth. Zn and B contents are also essential nutrients for human health. There has been no research on the effects of Zn and B as biofortification on the Srikandi variety corn (non-hybrid). This study aimed to determine the effect of Zinc and Boron spraying on growth, productivity, seed quality, and Zn and B content in the Srikandi variety. This experiment consisted of four treatments of Zinc and Boron spraying on leaves, namely (1) Zinc 0% + Boron 0%; (2) Zinc 0.5% + Boron 0.5%; (3) Zinc 1% + Boron 1%; (4) Zinc 2% + Boron 1.5%. The results showed that Zn and B applications significantly affected the growth, seed quality, and nutritional content of the Srikandi variety corn. Application of Zn 1% + B 1% was the best treatment for increasing the number of leaves, stover weight, seed germination and vigour, growth homogeneity, and Zn and B content in corn.
