USE OF TRICHODERMA SPP. ISOLATES AS GROWTH PROMOTERS AND MELA DISEASE RESISTANCE INDUCERS FOR COWPEA CULTIVATION

Abstract

Cowpea has great social and economic importance, but several diseases affect it, causing low production. Thus, the objective of this study was to use Trichoderma spp. Isolates as growth promoters in cowpea crops. For this, the seeds were microbiolized with Trichoderma spp. Isolates and planted in the field. The experimental design was in randomized blocks, the treatments consisted of isolates L1 and I1, each one composing a treatment with liquid application and another in powder, a commercial product based on Trichoderma harzianum and the control, thus composing the 6 treatments, which were divided into 4 blocks. Physiological parameters, growth promotion, induction of disease resistance, and productivity were evaluated.  The data obtained were submitted to ANOVA and Tukey's test at 5% probability. No statistical differences were observed between the treatments and the control for the parameters evaluated.
