- Spectral data are provided for both treated and control samples.
- The dataset supports chemometric analysis and regulatory screening.

## Abstract

This dataset provides Attenuated Total Reflectance–Fourier Transform Infrared (ATR-FTIR) spectra of Cannabis sativa L. leaves from five industrial hemp varieties cultivated under field conditions in Paraguay. In total, the dataset comprises 80 ATR-FTIR spectra, corresponding to five varieties, two treatment conditions, and eight biological replicates per combination. The dataset includes raw spectral profiles from placebo-treated controls and samples treated with a Trichoderma-based biomass suspension, organized in individual and consolidated Excel tables. These data support varietal classification, evaluation of treatment-related spectral variation, spectral library development, and applications in quality control, chemometric analysis, and preliminary regulatory screening.
