• Resumen

  • Liquid biofertilizers, promoted by regenerative agriculture, aspire to sustainability. In this sense, the combination of concentrations of a super-lean bioslurry (BSm) based on bovine manure ("Factor A", A1: 0 ml/l control, A2: 3.5 ml/l A3: 7 ml/l and A4: 10 ml/l) and shading levels ("Factor B" B1: full sun, B2: 35% and B3: 70%), on the growth and development of Etlingera elatior was evaluated. The BSm applications were dosed in four applications, distributed over 210 days via foliar application, carrying out: measurement of plant height to the last leaf in cm (ATA cm) and rhizome weight in grams (Rz g). A randomized block design with a 4 X 3 factorial arrangement was used, resulting in twelve treatments and three replicates (36 observation units), measured at the end of the bioassay. An analysis of variance and orthogonal contrast test were applied, using the Infostat program. The results of the orthogonal contrast tests show that for the variable ATA cm, there was a negative effect when increasing the concentrations of BSm (p-value of 0.0423 < 0.05), "Factor A"; in relation to "Factor B", no significant difference was found p-value (0.4003> 0.05); as for the weight of the Rhizome (Rz g), significance was observed at α 0.05, with a shade level of 35%, without the concentrations of BSm being a determining factor.
