Tóm tắt

Zinc (Zn) is a micronutrient, which is involved in activating many physiological and biochemical processes. The Zinc deficiency is a worldwide nutritional constraint for crop production in many types of soil, particularly in maize growing. This study was carried out in 2019 summer - autumn to evaluate the effect of ZnO nano fertilizer on growth, yield and quality of Maize (Zea mays L) in Phu Binh, Thai
Nguyen. In one crop maize were sprayed with ZnO nano fertilizer with 5 fertilizer formulas: 10ppm ZnO/m2, 30ppm ZnO/m2, 50ppm ZnO/m2, 70ppm ZnO/m2 and one control formula in which no ZnO nano was used. The results showed that dose 50ppm ZnO/m2/crop resulted was the best formula, highest yield, increased more 23,7% compared with the control formula. These results have important
implications for guiding the rational application of ZnO nano fertilizer and improving the grain yield of maize in Thai Nguyen province
