Abstract:
The present research evaluated the native fungus Trichoderma asperellum with registration MT044384 in National Center Biotechnology (NCBI), USA, to know its mechanism of action as a biostimulant for growth and yield of white native corn. A concentration of 1x108 spores/ml of T. asperellum was evaluated, which was sprayed on the foliage of the plant every 21 days until spike formation, with a combination of the biostimulant fungus and compost, and control treatments without the fungus and without compost. The experiment was distributed in a completely randomized design with three repetitions, in field and greenhouse conditions. An analysis of variance and comparison of treatment means was performed with the Tukey test with significance of p<0.0001. T. asperellum stimulated native corn plant height and yield variables in greenhouse and field conditions compared to control treatments. The best corn grain yield was obtained in T. asperellum in the greenhouse with 9.40 ton/ha, followed by T. asperellum plus compost in the field with 8.92 ton/ha, both treatments were significantly equal, this represents an average of up to 60 percent. percent in relation to control treatments. The highest height was 372.5 cm in T. asperellum in the greenhouse. The native strain T. asperellum MT044384 is potentially a good alternative to increase the yields of native corn.
