Abstract
BERNAL-MONTERROSA, Miguel Ángel and CABRALES-HERRERA, Eliecer Miguel. Response of Valery clone banana in high density to inoculation with mycorrhizae and phosphorus in Apartado - Colombia. rev.udcaactual.divulg.cient. [online]. 2022, vol.25, n.2, e1659.

The banana crop in Uraba Antioqueño has been presenting a decrease in the yields, which requires the search for alternatives to increase or maintain current production, among which is the increase in the proportion of inorganic fertilizers leading to cost overruns and environmental problems. In view of this situation, there has been a growing interest in the use of biofertilizers such as mycorrhiza (HFM) with which multiple benefits to the soil-plant system have been demonstrated. The objective of this research was to evaluate the effect of HFM with the reduction of phosphorus dose in the Valery banana clone under a high-density system under edaphoclimatic conditions of Apartado-Antioquia. For this purpose, 100 g of commercial HFM were inoculated with 5 doses of phosphorus at time of sowing, corresponding to: 0, 25, 50, 75 and 100 kg*ha-1. Morphological variables, performance and mycorrhizal symbiosis were measured. The experimental design was completely random with 3 repetitions, each experimental unit was made up of 10 plants contained in 5 sites. The information was processed with the statistical program SAS 9.1, variance analysis was obtained and a mean comparison test (Tukey) with a significance level of 95 %. No significant differences were found in the morphological variables, but in the productive variables, the HFM + 50 Kg P2O5*ha-1 treatment was the best and also presented the highest percentage of mycorrhizal colonization with 59.5 %.
