Agronomic behavior of six non-psychoactive Cannabis sp. genotypes under greenhouse in the high Andean tropics of Colombia. Cienc. Tecnol. Agropecuaria [online]. 2023, vol.24, n.1, e2698.  Epub 30-Abr-2023. ISSN 0122-8706.  https://doi.org/10.21930/rcta.vol24_num1_art:2698.

Within the framework of Decree 613 of 2017, which regulates Law 1787 of 2017, the legal production of cannabis for medical and scientific use begins in Colombia. As it is a crop with no legal history in the country, it is necessary to carry out an agronomic evaluation test (AET), through which its stability in a determined subregion is demonstrated, during a complete cycle. This study presents the results of an AET carried out in the Andean zone of moderate cold (from 1800 to 2200 m asl) in the eastern department of Antioquia, Colombia, under plastic cover, with six genotypes of non-psychoactive cannabis (THC < 1%) pre-existing in the seed source registered with the ICA. The evaluation was carried out between September 30, 2019, and January 15, 2020. The genotypes were spatially distributed based on a randomized complete block design, with three replicates per genotype and 20 plants per experimental unit, planted at a density of four plants per square meter. The total fresh biomass (stem, leaves and inflorescences) per square meter presented a general average of 3525.62 g, of which 775.42 g (22 %) corresponded to the flowers. The flowers had an average content of 10.70% CBD and 0.47% THC. These materials are classified as non-psychoactive, in accordance with Colombian regulations, and can therefore be used for any of the purposes established in Section 5 of Decree 613 of 2017.
