Mycorrhizas play an important role in the increase of the absorption rate of nutrients and the improvement of plant growth in diverse agroecosystems. With the aim to demonstrate the beneficial effects of mycorrhizas in plant growth and nutrition, and management field techniques, a research work was done, in five producer farms located in the municipality of Restrepo, Colombia. Two mixtures of mycorrhizas (native and introduced) and 3 substrates types (soil-sand (1:1), soil-sand-rice husk (2:2:1), and soil-sand-pork compost (2:2:1)) were compared in five perennial species (Citrus reshni, Eugenia stipitata, Bactris gasipaes, Persea americana and Anadenanthera peregrina). Plant growth parameters included plant height, stem diameter, root volume and biomass, as well as, nutrient absorption were taken. In mandarin Cleopatra, a greater relative increase was observed in plant height (131%), stem diameter (75%), root volume (116%) and biomass (122%) with the use of introduced mycorrhiza and soil-sand-pork compost substrate. In Araza, a significant increase in plant growth was also observed with the use of introduced mycorrhiza and soil-sand substrate. The other species showed a significant increased in some of the plant growth due to mycorrhizas and the substrate. Significant differences in plant nutrient absorption within the perennial species were noted among mycorrhizas and substrate types. |
