Efecto de Trichoderma spp. y Clonostachys spp. en el desarrollo de dos especies forestales, ciprés (Cupressus macrocarpa) y tara (Caesalpinia spinosa) a nivel de vivero

Abstract

The objective of the research was to determine the effect of Trichoderma spp. and Clonostachys spp. on the development and growth of two forest species, Cypress (Cupressus macrocarpa) and Tara (Caesalpinia spinosa). A randomized complete block design (R.C.B.D.), bifactorial (Factor A: forest species, Factor B: Trichoderma spp. and Clonostachys spp.), with 6 treatments and 4 replicates was used. The trial involved the seed collection, substrate preparation, sheathing, inoculum preparation of Trichoderma spp. and Clonostachys spp., sowing of Cypress (Cupressus macrocarpa) and Tara (Caesalpinia spinosa), inoculation of Trichoderma spp. and Clonostachys spp., irrigation, analysis of the variables; number of leaves, diameter at the height of the neck (DAC), weight and height phases. In summary, for the variables height and fresh weight in the Cypress species (Cupressus macrocarpa) the treatment of Trichoderma harzianum is the one that better acted in the development of the species; on the other hand, for the species of Tara (Caesalpinia spinosa) none of the Treatments influenced, since in this case predominates the Control treatment, and in conclusion it was determined that none of the treatments had an effect in the evaluated variables such as; number of total leaves, total height, diameter at the height of the neck (DAC) and fresh weight in the development of the two forest species, Cypress (Cupressus macrocarpa) and Tara (Caesalpinia spinosa), when applying Trichoderma spp. and Clonostachys spp, it is recommended to carry out studies where Trichoderma harzianum and Clonostachys spp. are combined with organic fertilizers (manure, compost) to determine or analyze the growth and development of plants.
