Microbe-mediated enrichment of crops has emerged as an environment-friendly intervention to tackle the problems of eroding soil fertility and malnutrition globally. The responses of a set of ten biofortified maize genotypes to three cyanobacterial inoculants (cyanobacterial consortium BF1-4, Anabaena sp.–Trichoderma sp. biofilm-An-Tr and Anabaena sp.+ Providencia sp. -CR1 + PR3) were evaluated over a period of two years. Significant genetic variation existed among the maize inbreds for all soil microbial parameters, soil macronutrients (N and P) and micronutrients (Mn and Zn), besides physiological and nutritional quality traits. Genotype x Inoculants interaction was more significant for soil glomalin (32 %), organic carbon (26 %), soil polysaccharides (20 %) and soil available N (18 %). Genotype x inoculants x environment (years) interactions significantly influenced available Zn (36 %), organic carbon (31 %), glomalin (30 %), available N (20 %) and polysaccharides (20 %). Promising genotype-inoculant combinations of PMI-Q2+ BF1-4 or An-Tr, PMI-PV2+BF1-4 or CR1 + PR3, HP-467-13 + BF 1-4 or An-Tr were identified, which can be evaluated across agro-ecologies. It was concluded that cyanobacterial inoculation can lead to N savings, improved soil fertility and enhanced crop vigor in maize.

微生物介导的作物富集已成为解决全球土壤肥力下降和营养不良问题的环保干预措施。一组 10 种生物强化玉米基因型对三种蓝藻接种剂（蓝藻菌群 BF1-4、鱼腥藻-木霉属生物膜-An -Tr 和鱼腥藻 +普罗维登西亚）的反应sp. -CR1 + PR3) 进行了为期两年的评估。除了生理和营养品质特征外，玉米自交系的所有土壤微生物参数、土壤常量营养素（N 和 P）和微量营养素（Mn 和 Zn）都存在显着的遗传变异。基因型 x 接种剂的相互作用对于土壤球藻蛋白 (32 %)、有机碳 (26 %)、土壤多糖 (20 %) 和土壤有效氮 (18 %) 更为显着。基因型 x 接种剂 x 环境（年）相互作用显着影响可用锌 (36 %)、有机碳 (31 %)、球藻蛋白 (30 %)、可用氮 (20 %) 和多糖 (20 %)。确定了 PMI-Q2+ BF1-4 或 An-Tr、PMI-PV2+BF1-4 或 CR1 + PR3、HP-467-13 + BF 1-4 或 An-Tr 的有前途的基因型接种组合，可以对其进行评估跨越农业生态。
