This study evaluated the effect of planting density, Trichoderma harzianum, and Effective Microorganisms (EM) on the agronomic performance of Sesamum indicum L. under humid tropical conditions in Pichari, Peru, during the 2024 agricultural season. A randomized complete block design with a 2 × 2 × 2 factorial arrangement was used, including two planting densities (119,000 and 143,000 plants ha⁻¹), with or without application of T. harzianum and EM. Growth variables and yield components, including plant height, capsule number, and grain yield, were evaluated. Significant effects were observed for the interaction between T. harzianum and EM on grain yield (p = 0.0424). The highest yield (1,252 kg ha⁻¹) was obtained with the treatment combining T. harzianum and 143,000 plants ha⁻¹. In addition, treatments inoculated with T. harzianum showed higher numbers of capsules per plant compared with non-inoculated treatments. The results indicate that microbial inoculation, particularly with T. harzianum, may contribute to improving sesame productivity under tropical field conditions in the Peruvian Amazon.
