The efficacy of seed priming and foliar application of zinc-amino acid chelates including zinc-histidine [Zn(His)₂] and zinc-methionine [Zn(Met)₂] in comparison with zinc sulfate (ZnSO₄) on yield and grain nutritional quality of two common bean cultivars (Phaseolus vulgaris L., cvs Talash and Sadri) was investigated in a severely Zn-deficient calcareous soil (DTPA-Zn: 0.38 mg kg⁻¹ soil) in a pot experiment. Bean response to Zn application varied depending on the Zn fertilizer, application method and cultivar. In ‘Talash’, seed priming with [Zn(His)₂] and [Zn(Met)₂] led to 24.1 and 11.6% increase in the grain yield of bean in comparison with ZnSO₄ treatment, respectively. In both cultivars, foliar application of [Zn(His)₂] led to significant increase in the grain yield in comparison with ZnSO₄. The highest grain Zn concentration was obtained by seed priming with [Zn(Met)₂] in ‘Sadri’ and [Zn(His)₂] in ‘Talash’, respectively. For Zn-amino acid chelates, seed priming was more effective than foliar application in increasing grain yield and Zn concentration. Foliar application of [Zn(His)₂] and [Zn(Met)₂] in ‘Sadri’ and [Zn(Met)₂] in ‘Talash’ resulted in higher protein content in bean grain as compared with ZnSO₄. In both cultivars, foliar application of [Zn(Met)₂] was the more effective than seed priming to increase grain protein content. The highest water-soluble carbohydrates concentration of grain was obtained by seed priming with [Zn(Met)₂] and [Zn(His)₂] in ‘Sadri’ and ‘Talash’ cultivars, respectively. Therefore, seed priming with [Zn(His)₂] and ZnSO₄ in ‘Sadri’ and [Zn(Met)₂] in ‘Talash’ can effectively be used for improving yield of common bean in Zn-deficient calcareous soils.

与硫酸锌（ZnSO ₄）相比，包括锌组氨酸[Zn（His）₂ ]和蛋氨酸锌[Zn（Met）₂ ]的锌氨基酸螯合物的种子引发和叶面施用对产量和谷物营养的功效在盆栽试验中，在锌缺乏严重的钙质土壤（DTPA-Zn：0.38 mg kg ^-1的土壤）中研究了两个常见豆品种（菜豆，vul Talash和Sadri）的品质。豆类对锌的施用响应因锌肥，施用方法和品种而异。在'Talash'中，与ZnSO相比，用[Zn（His）₂ ]和[Zn（Met）₂ ]引发种子使豆的谷物产量增加了24.1和11.6％。分别治疗_4次。在两个品种中，与ZnSO ₄相比，叶面施用[Zn（His）₂ ]导致谷物产量显着增加。通过分别用'Sadri'中的[Zn（Met）₂ ]和'Talash'中的[Zn（His）₂ ]进行底漆处理可获得最高的籽粒Zn浓度。对于锌氨基酸螯合剂，在增加谷物产量和锌浓度方面，种子引发比叶面施用更有效。叶面施用'Sadri'中的[Zn（His）₂ ]和[Zn（Met）₂ ]和'Talash'中的[Zn（Met）₂ ]导致豆粒中的蛋白质含量高于ZnSO ₄。在两个品种中，[Zn（Met）的叶面施用₂ ]比起种子更有效地增加谷物蛋白含量。通过分别在'Sadri'和'Talash'品种中用[Zn（Met）₂ ]和[Zn（His）₂ ]进行底漆处理，获得了谷物中最高的水溶性碳水化合物浓度。因此，用'Sadri'中的[Zn（His）₂ ]和ZnSO ₄和'Talash'中的[Zn（Met）₂ ]进行种子引发可以有效地提高缺锌石灰性土壤中普通豆的产量。
