In response to growing concerns about the environmental and economic impacts of chemical fertilizers, this study explores the potential of biofertilization using native Rhizobium strains to enhance the growth, yield, and quality of Solanum lycopersicum (tomato) under field conditions. The experiment assessed the effects of Rhizobium biofertilization on plant performance and soil microbial communities by applying R. calliandrae, R. jaguaris, R. mayense, and a bacterial consortium, in comparison to conventional chemical fertilization. Key parameters such as plant height, fruit yield, macronutrient and micronutrient content, and fruit quality (lycopene and β-carotene levels) were measured. Results showed that R. calliandrae and R. jaguaris significantly enhanced fruit yield, nitrogen, potassium, manganese, and boron levels, while also improving fruit quality compared to the control. The impact of strain inoculation on the structure of the microbial community was also examined. Metataxonomic analysis of rhizospheric soils revealed no significant changes in microbial diversity, indicating that biofertilization with Rhizobium strains promotes plant growth without disrupting the composition of the soil microbiome. These findings suggest that Rhizobium biofertilization is a viable and sustainable alternative to chemical fertilizers, providing benefits to both crop productivity and soil health while minimizing the environmental footprint associated with conventional agricultural practices. The study underscores the importance of carefully selecting bacterial species with complementary functions to maximize the effectiveness of biofertilization strategies.
鉴于对化肥环境和经济影响的担忧日益增加，本研究探讨了使用本地根瘤菌菌株进行生物施肥，以在田间条件下提高番茄生长、产量和品质的潜力。通过施用卡氏根瘤菌、美洲豹根瘤菌、马耶恩斯根瘤菌和一个细菌联合体，与传统化学施肥相比，该实验评估了根瘤菌生物施肥对植物性能和土壤微生物群落的影响。测量了诸如株高、果实产量、大量营养素和微量营养素含量以及果实品质（番茄红素和β-胡萝卜素水平）等关键参数。结果表明，与对照相比，卡氏根瘤菌和美洲豹根瘤菌显著提高了果实产量、氮、钾、锰和硼含量，同时还改善了果实品质。还研究了菌株接种对微生物群落结构的影响。对根际土壤的宏分类分析表明微生物多样性没有显著变化，这表明用根瘤菌菌株进行生物施肥可促进植物生长，而不会破坏土壤微生物组的组成。这些发现表明，根瘤菌生物施肥是一种可行且可持续的化肥替代方案，在使与传统农业实践相关的环境足迹最小化的同时，为作物生产力和土壤健康带来益处。该研究强调了仔细选择具有互补功能的细菌物种以最大化生物施肥策略有效性的重要性。
