Field experiments were carried out to study the effect of dual inoculation of Arbuscular Mycorrhizal (AM) fungi and its associated bacteria (Pseudomonas putida strain PAN4 - NCBI accession no. HM590707.1) to enhance the yield of sapota (var. DHS-2, Ten-year old sapota plants were supplied with the mixed culture of AM fungi (Funneliformis mosseae, Rhizophagus fasciculatus and Rhizophagus intraradices) with or without P. putida along with two levels of fertigation i.e. 100% recommended dose of fertilizers (RDF) and 75% RDF. AM fungal root colonization and spore proliferation, leaf nutrient concentration and yield were significantly higher with 75% RDF along with AM fungi and P. putida treated plants as compared to other treatments. Plants inoculated with 75% RDF along with AM fungi and P. putida recorded higher AM fungal colonization (45.7%) and AM fungal spore population (61.7%) as compared to 100% RDF. The leaf nutrient concentrations i.e. nitrogen, phosphorus, potash, calcium, magnesium, iron, manganese, zinc and copper increased by 17.4, 38.8, 20.5, 7.1, 10.3, 15.1, 16.6, 25.6 and 4.37% respectively compared to 100% RDF. The pooled data of yield indicated that application of 75% RDF along with AM fungi and P. putida significantly increased the yield as compared to 100% RDF. It was evident that regular application of AM fungi and its associated bacterium i.e. P. putida with 75% RDF significantly improved the plant nutrient uptake, AM fungal root colonization, spore proliferation and yield in sapota under field conditions. © 2021 World Research Association.
