Abstract

The Kerecaya community (3700-4000 msnm) of the municipality of Salinas of Garci Mendoza of the south altiplano of Bolivia, in spite of your climatics risks. The plots of quinoa present lower organic matter to 0.93%, humidity of the smaller earth to 12.9%, temperature of the earth for under 8.5 oC and pH lower to 8.0. The population of funguses in three types it has studied of earths that went: without farm (without entropic intervention), traditional and mechanized. The humid samples of the earth were gathered to a depth of 6 to 25 cm at random in zig-zag, these to be prosecuted by means of the method of seriate dilution and inoculated in plates with 0.5 mL and it is evaluated the colonies for UFC´s/g of earth, the genre of Penicilli-um spp., with major population of 65.1%, followed for Aspergillus spp., with 24,1% and Trichoderma spp., with minor great quality of 13,8% and the population average in UFC´s/g of earth it went of 1035.4 in with-out farm (without entropic intervention), 959.7 in traditional and 868.2 in the mechanized and the major population was presented in the month of February 1572.8 UFC/g of earth.
