- PublicaciónAcceso abiertoEfecto de consorcios PGPR sobre el desarrollo de plantas de Plukenetia volubilis Y Moringa oleífera hasta fase vegetativa en comparación a fertilización convencional y orgánica en campo(Bucaramanga : Universidad de Santander, 2019, 2019-06-22) Ramírez Zuleta, Edgar Alexander; Acevedo Isidro, Carlos-Augusto; Agualimpia Valderrama, Bayron-Enrique; Pérez Pulido, Miguel-OswaldoThe use of PGPR bacteria increases crop yields, improving resistance mechanisms, reducing diseases and favoring growth and development. Therefore, the objective of this work was to evaluate the PGPR activity of the microbial consortia until the vegetative phase in plants of Plukenetia volubilis and Moringa oleifera, under different fertilization systems. To fulfill this objective, 700 seeds were used for each species, which were distributed equally in 9 treatments and one control. Initially, the seeds were inoculated with the consortia according to the treatment to determine the percentage and speed of germination. Subsequently, the germinated seedlings were taken to the final site where, every 8 days, the non-destructive data collection was made and 15 days after the destructive analysis; measuring growth variables stem length and diameter, number of leaves, leaf area, root length, dry weight of leaves, stem and root; as well as the presence of microorganisms that make up the consortiums to later evaluate the PGPR activity. The results obtained allowed to observe that treatments 4 and 5, are those that obtain the best percentage and speed of germination for sacha inchi; while moringa with treatment 3. In the evaluation of the growth variables for sacha inchi, treatments 1, 2 and 3 increase the average number of leaves, length and stem diameter with respect to the control. However, in the accumulation of total biomass, treatment 4, obtained the best yield for dry weight of leaves, stem and root. Similarly, treatment 6, obtain an average root length higher than the other treatments. For the variables stem length and diameter evaluated in moringa, treatment 9 showed values above the other treatments.
