Agricultural growers worldwide face significant challenges in promoting plant growth. This research introduces a green strategy utilizing nanomaterials to enhance crop production. While high concentrations of nanomaterials are known to be hazardous to plants, this study demonstrates that low doses of biologically synthesized zinc oxide nanoparticles (ZnO NPs) can serve as an effective regulatory tool to boost plant growth. These nanoparticles were produced using seed extract and characterized through UV-Vis spectroscopy, FT-IR, X-ray diffraction, and scanning electron microscopy (SEM). The antifungal properties of ZnO NPs were evaluated against , the causative agent of Cercospora leaf spot in mung bean. Application of ZnO NPs significantly improved plant metrics, including shoot, root, pod, leaf, and root nodule counts, as well as plant length, fresh weight, and dry weight-all indicators of healthy growth. Moreover, low-dose ZnO NPs positively influenced enzymatic activity, physicochemical properties, and photosynthetic parameters. These findings suggest that biologically synthesized ZnO NPs offer a promising approach for enhancing crop yield and accelerating plant growth.
全球的农业种植者在促进植物生长方面面临重大挑战。本研究引入了一种利用纳米材料提高作物产量的绿色策略。虽然已知高浓度的纳米材料对植物有害，但本研究表明，低剂量的生物合成氧化锌纳米颗粒（ZnO NPs）可以作为促进植物生长的有效调控工具。这些纳米颗粒是用种子提取物制备的，并通过紫外可见光谱、傅里叶变换红外光谱、X射线衍射和扫描电子显微镜（SEM）进行了表征。评估了ZnO NPs对绿豆尾孢叶斑病病原菌的抗真菌特性。ZnO NPs的应用显著改善了植物指标，包括茎、根、豆荚、叶和根瘤数量，以及株高、鲜重和干重——所有这些都是健康生长的指标。此外，低剂量的ZnO NPs对酶活性、理化性质和光合参数产生了积极影响。这些发现表明，生物合成的ZnO NPs为提高作物产量和加速植物生长提供了一种有前景的方法。
