Maize and soybean crop under rhizobacteria and foliar bio-fertilizer treatment

The experiment used a randomized block design with four treatments (T0-T3) and four replicates for each maize (DMRESR-Y and EV99-MRP, improved seed of maize varieties are available at the National Agricultural Research Centre; CNRA of Côte d'Ivoire) and soybean variety. Of note, the soybean seeds were purchased from the local market under the common name of yellow soybeans and green soybeans. Each 4 × 4 m plot contained four 4 m long rows, with 75 cm between rows and 40 cm between plants (two per hill after thinning). Treatments were T0, control (no P. fluorescence or foliar fertilizer); T1, seeds inoculated with P. fluorescence; T2, seeds inoculated with P. fluorescence plus foliar biofertilizer; and T3, foliar fertilizer only. The plots were maintained with monthly weeding and relied solely on rainfall. Twenty samples per treatment and replicate were collected to evaluate the growth, yield, and dry biomass for statistical analysis.
