ABSTRACT - Inoculation of microorganisms in plants performs important functions related to plant growth and nutrition.
The responses are based on hormonal stimulation and improved absorption and effi ciency in the use of nutrients. Thus, the
objective of this study was to evaluate the ability of Trichoderma strains (T. longibrachiatum and T. asperellum) to promote
growth and improve the nutrition in dwarf cashew rootstock. The experiment was conducted in a shade net house with 50%
of shading located in the Experimental Field of Pacajus, belonging to Embrapa Agroindústria Tropical, in Pacajus/CE, Brazil.
The experimental design used was completely randomized, with three treatments and ten replicates. Each experimental unit
consisted of a tube with a 288 cm3  capacity containing one seedling of dwarf cashew. At sixty days (60) after germination,
the plants were evaluated for biometric parameters, Dickson’s quality index, and nutritional diagnosis of leaves. To verify the
growth-promoting mechanisms, the strains were reisolated by indirect plating of roots. Nutrient accumulation in the leaves
was not infl uenced by the application of the isolates; however, the seedlings were adequately supplied. The strains showed
similarities in relation to growth-promotion mechanisms. The Trichoderma longibrachiatum strain promoted an increase in the
growth, so its use as a supplement for the planting substrate is recommended.

RESUMO - A inoculação de microrganismos em plantas desempenha funções importantes ligadas ao crescimento e a nutrição
do vegetal. As respostas são baseadas na estimulação hormonal e na melhoria da absorção e efi ciência no uso dos nutrientes.
Assim, objetivou-se avaliar a capacidade de cepas de Trichoderma (T. longibrachiatum e T. asperellum) em promover o
crescimento e melhorar a nutrição de porta-enxerto de cajueiro-anão. O experimento foi conduzido em telado com 50% de
sombreamento, localizado no Campo Experimental de Pacajus, pertencente a Embrapa Agroindústria Tropical, em Pacajus/
CE. O delineamento experimental utilizado foi inteiramente casualizado, com três tratamentos e dez repetições. Cada unidade
experimental foi constituída por um tubete de 288 cm3  de volume contendo uma muda de cajueiro-anão. Aos sessenta (60)
dias após a germinação, as plantas foram avaliadas quanto aos parâmetros biométricos, o índice de qualidade de Dickson, e
a diagnose nutricional das folhas. Para verifi car os mecanismos promotores de crescimento, as cepas foram reisoladas pelo
plaqueamento indireto de raízes. O acúmulo de nutrientes nas folhas não foi infl uenciado pela aplicação dos isolados, contudo,
as mudas estavam supridas adequadamente. As cepas apresentaram semelhanças em relação aos mecanismos de promoção
do crescimento. A cepa Trichoderma longibrachiatum promoveu aumento do crescimento do porta-enxerto, sendo, portanto,
indicada a sua utilização como suplemento do substrato de plantio.
