Applications of metal oxide nanoparticles in the agriculture sector are being extensively included as the materials are considered superior. In the present work, zinc oxide nanoparticle (ZnO NPs), with a developing fertilizer, is applied in the fortification of rice grain yield and nutrient uptake enhancement. To evaluate the role of ZnO NP, two field experiments were conducted during the 2018 and 2019 seasons. ZnO NPs were small, nearly spherical, and their sizes equal to 31.4 nm, as proved via the dynamic light scattering technique. ZnO NPs were applied as a fertilizer in different concentrations, varying between 20 and 60 mg/L as a foliar spray. The mixture of ZnSO and ZnO NP ameliorated yield component and nutrients (N, K, and Zn) uptake was enhanced compared to traditional ZnSO treatment. Nevertheless, the uptake of the phosphorous element (P) was adversely affected by the treatment of ZnO NPs. Thus, treatment via utilizing ZnO NPs as a foliar with a very small amount (40 ppm) with of basal ZnSO led to a good improvement in agronomic and physiological features; eventually, higher yield and nutrient-enriched rice grain were obtained.
金属氧化物纳米颗粒在农业领域的应用正被广泛采用，因为这些材料被认为具有优越性。在本研究中，氧化锌纳米颗粒（ZnO NPs）与一种新型肥料一起被用于提高水稻产量和增强养分吸收。为了评估ZnO NP的作用，在2018年和2019年季节进行了两项田间试验。通过动态光散射技术证明，ZnO NPs很小，近乎球形，其尺寸等于31.4纳米。ZnO NPs作为肥料以不同浓度进行叶面喷施，浓度在20至60毫克/升之间。与传统的硫酸锌（ZnSO）处理相比，ZnSO和ZnO NP的混合物改善了产量构成要素，增强了养分（氮、钾和锌）的吸收。然而，磷元素（P）的吸收受到ZnO NPs处理的不利影响。因此，将ZnO NPs作为叶面肥以非常少量（40 ppm）与基肥ZnSO一起使用，导致农艺和生理特性有良好改善；最终，获得了更高产量和营养丰富的水稻籽粒。
