The Cowpea (Vigna unguiculata (L.) Walp.) is known as macassar bean and colony bean. In addition to its economic importance, it has high nutritional contents, being a substitute for animal protein. Fungi of the genus Trichoderma are known to be biological controllers and for their versatility. This work aimed to evaluate the effect of Trichoderma spp. on the growth of cowpea plants. Fifteen Trichoderma isolates and one cowpea genotype were used. The bioassay was completely randomized, repeating once. The isolates were multiplied in parboiled rice. From each isolate, a suspension of conidia adjusted to 106 conidia mL-1 was prepared, each plant receiving 25 mL of the suspension, evaluating 30 days after inoculation, plant height, weight of green mass and dry mass. Ten isolates provided gains in height of the treated plants, differing on average from the control in the two bioassays performed. Plants treated with T 12.11 and T 5.16 had increases in green and dry mass weight in all bioassays and in all analyzed variables. The use of Trichoderma species to promote growth in cowpea represents a viable alternative for farmers. The most promising isolates T 2.24 and T 2.54 from the species T. asperelloides, and T 5.16 and T 12.11 from Trichoderma spp. can be used to increase dry matter in cowpea, requiring studies in order to visualize greater commercial production and to develop more practical forms of inoculation.
