Plant Growth Promoting Bacteria in Hydroponics Production of Lettuce

To complement the hydroponics production technology with organic components and to find lower cost of producing quality lettuce, plant growth promoting rhizobacteria (PGPR) were tested in SNAP-based static hydroponics lettuce production. The study was laid out in RCBD with 3 replications testing the following treatments under semi-controlled greenhouse environment in Mindanao, Philippines (453m ASL): T1 - Tap Water; T2 - Recommended Rate (RR) SNAP; RR SNAP + Azospirillium spp; T3 - RR SNAP + MykoVAM; Recommended Rate SNAP + MykoPLUS; ¿ Recommended Rate SNAP; ¿ Recommended Rate SNAP + Bio-N; ¿ Recommended Rate SNAP + MykoVAM; ¿ Recommended Rate SNAP + MykoPLUS; Tap Water + Bio-N; Tap Water + MykoVAM and Tap Water+ MykoPLUS. Growth, production and economics of lettuce grown in SNAP-based static hydroponic system with SNAP are positively affected by the inoculation of PGPR present in Bio-N and MykoPLUS products.
