Abstract:
Biofertilizers management for sustainable agriculture is a challenge to improve farmers ‘food security today and correct nutrient deficiencies (potassium, phosphorus and nitrogen) in plant.
As biofertilizers, mycorrhizal symbiosis plays an important role in nutrient uptake and the productivity of plants. The aim of this study was the Rhizobium and mycorrhizal inoculations effect on plant growth and mineral nutrition of snap bean variety "Contender" in greenhouse condition.
The experiment was a randomized block design with four treatments: a control non-inoculated, dual inoculation with Serendipita indica (S.indica) and Rhizobium tropici Ciat 899 strain (Ciat 899), dual inoculation with Rhizophagus irregularis (R. irregularis) and Ciat 899, and combined inoculation with R. irregularis, S.indica and Ciat 899 ; using eight replicates per treatment.
Ciat 899 associated with S.indica or R. irregularis significantly increased plant growth parameters, and shoots and root phosphorus concentrations. It shows higher biomass production, pod number, nodule number and phosphorus content than plants inoculated with triple strains and non-mycorrhizal plants. Thus, the colonization rate exceeds 80%.
The results of this study show that dual inoculation with Rhizobium and mycorrhizal fungi enhance significantly productivity in common bean.
