Use of Bioinoculants Affects Variation in Snap Bean Yield Grown under Deficit Irrigation

The use of beneficial microorganisms, such as plant growth promoting rhizobacteria (PGPR) and mycorrhizal fungi, for organic farming could improve the productivity resilience vegetable crops. Both PGPR PGPF are allowed farming, they represent new important tools regenerating poor marginal soils in transition to environmentally friendly farming. In experiment, effects PGPM-based products were evaluated on snap bean combination with two irrigation regimes. experimental design adopted was split-plot, main plot represented by regime (reintegration 100 60% ETc), sub-plot microbial consortia, finally sub-sub-plot genotype (‘Domino’ ‘Maxi’). Seeds sown a cold greenhouse growing cycle finished after 86 days from sowing. results showed significant increase yield due application PGPM compared control. deficit applied (ETc 60%) affected plants genotypes their related production differently (in average 2.20 kg m−2 Domino 3.63 Maxi), showing positive effect 2.47 without 3.36 PGPM) product quality. Furthermore, an interesting negative correlation between number nodules also observed, consequence early outcome which increased relation factors.
