Efecto de asociación de Micorrizas y Trichodermas spp sobre el crecimiento de plantas de plátano (Musa ABB) en la etapa de vivero.

Abstract

The effect of Mycorrhizae in association with Trichodermas spp. in 216 plantain scallions (Musa ABB) and measure the vegetative growth in the nursery stage, for which 6 treatments and a control were available, where greater vegetative activity was observed both in the leaf area and in the root area were the treatments 1 (100g of Mycorrhizae and 50ml of Trichodermas spp) reaching an average plant height of 20.98 cm and treatment 5 (150g of Mycorrhizae and 75ml of Trichodermas spp.) with an average height of 21 cm, compared to treatments 3 (100gr of Mycorrhizae and 100ml of Trichodermas spp.) with a plant height of 20.22 and treatment 6 (150g of Mycorrhizae and 100ml of Trichodermas spp.) with an average plant height of 19.13 cm which gave lower yield , this gives us to understand that the antagonistic response occurs at high doses of Trichodermas spp. compared to Mycorrhizae, that is, the greater the amount of Trichodermas spp., the greater the antagonism, but this stabilizes when the Mycorrhizae doses are higher. and this can be verified in the microbiological examination. Regarding the cost/benefit analysis, the cost does not differ much from one another, but this is differentiated in productivity at a higher rate, which ends up being profitable with treatments such as 1 (100g of Mycorrhizae and 50ml of Trichodermas spp.) that had a higher rate of gain in all the factors studied.
