Malnutrition is a problem in many developing economies where cereal crops are the main source of nutrition. Zinc and iron, important micronutrients, play an important role in the physiological and metabolic mechanisms of plants and humans. In this study a field experiment was conducted at the Agronomic Research Area, University of Agriculture, Faisalabad during zaid rabi season in February 2023 to check the impact of different application methods (seed priming, seed coating, soil application, and foliar application) of Zn and Fe on grain zinc and iron content and productivity in mungbean.. Results show that the plant growth parameters are significantly influenced by the concentration and application method of Zn and Fe. The highest plant height (cm), maximum number of branches and pods on plants were observed in foliar application of Zn and Fe combination treatment.. Post-harvest parameters, including biological yield, grain yield and 1000 seed weight were also positively influenced with highest biological yield (4536.27 kg ha) and grain yield (1927 kg ha) recorded under Zn foliar application. Physiological parameters such as chlorophyll content (SPAD value) and photosystem II Yield (Y(II)) were significantly improved with Zn and Fe treatment, particularly under foliar application. Biochemical analyses revealed that Zn and Fe significantly increase Zn and Fe content in grains with the highest value (36.77 and 63.44 ppm, respectively) observed under Zn foliar treatment. Overall, the foliar application was found most effective, in improving the yield and quality of mungbean. These findings highlight the efficacy of foliar application of Zn and Fe in enhancing mungbean growth, yield, and nutrient content, providing valuable insights for optimizing micronutrient management in mungbean cultivation.
营养不良是许多发展中经济体面临的一个问题，在这些经济体中，谷类作物是主要的营养来源。锌和铁是重要的微量营养素，在植物和人类的生理及代谢机制中发挥着重要作用。本研究于2023年2月在费萨拉巴德农业大学农艺研究区进行了一项田间试验，试验在斋德-拉比季节进行，以检验锌和铁的不同施用方法（种子引发、种子包衣、土壤施用和叶面喷施）对绿豆籽粒锌和铁含量及产量的影响。结果表明，锌和铁的浓度及施用方法对植株生长参数有显著影响。在锌和铁组合处理的叶面喷施中观察到最高的株高（厘米）、最多的分枝数和荚数。收获后的参数，包括生物产量、籽粒产量和千粒重也受到了积极影响，在锌叶面喷施处理下记录到最高生物产量（4536.27千克/公顷）和籽粒产量（1927千克/公顷）。锌和铁处理显著改善了叶绿素含量（SPAD值）和光系统II产量（Y(II)）等生理参数，特别是在叶面喷施处理下。生化分析表明，锌和铁显著提高了籽粒中的锌和铁含量，在锌叶面处理下观察到最高值（分别为36.77和63.44 ppm）。总体而言，叶面喷施被发现最有效地提高了绿豆的产量和品质。这些发现突出了锌和铁叶面喷施在促进绿豆生长、产量和养分含量方面的功效，为优化绿豆种植中的微量营养素管理提供了有价值的见解。
