ABSTRACT Common bean (Phaseolus vulgaris L.) is a leguminous species of great economic and nutritional importance worldwide, and thus the development of management strategies to promote plant growth and increase grain yield of legumes is of great interest to farmers. The growth-promoting effects of the symbiosis of endophytic microorganisms in plants have been exploited in several crops. This study investigated the effects of Induratia sp. endophytic fungi on the growth and grain yield of seed-inoculated common bean plants. The experiments were conducted in a greenhouse during two growing seasons using a randomized complete block design with three replicates. Growth and yield-related parameters such as plant height, root length, leaf index, number of days for flowering, number of pods per plant, number of grains per pod, mass of 100 grains, and grain yield were evaluated. The grain yield of plants inoculated with Induratia coffeana strains CML 4018 and CML 4020 and Induratia sp. strain CML 4015 increased by 52.5%, 48.9%, and 56.4% compared to the non-inoculated control, respectively. Seed inoculation of common bean plants with endophytic fungi species of the genus Induratia showed a beneficial interaction as indicated by the recorded increase in grain yield. The present pioneering study could provide the means for developing crop management strategies for enhancing common bean crop productivity. RESUMO O feijoeiro comum (Phaseolus vulgaris L.) é uma leguminosa de grande importância econômica e nutricional em todo o mundo; portanto, o desenvolvimento de estratégias de manejo para promover o crescimento das plantas e aumentar a produtividade de grãos é de grande interesse para os agricultores. Os efeitos da promoção de crescimento por simbiose de microrganismos endofíticos com plantas têm sido explorados em várias culturas. Este estudo investigou os efeitos sobre o crescimento e a produtividade de grãos em feijoeiro por meio de fungos endofíticos Induratia inoculados em sementes. Os experimentos foram conduzidos em casa de vegetação no delineamento de blocos completos casualizados com três repetições. Foram avaliados a altura de planta, comprimento de raiz, índice foliar, número de dias para o florescimento, número de vagens por planta, número de grãos por vagem, massa de 100 grãos e produtividade de grãos. A produtividade das plantas inoculadas com Induratia coffeana (CML 4018, CML 4020) e Induratia sp. (CML 4015) aumentou 52,5%, 48,9% e 56,4%, respectivame
