This paper reports the results of an experiment carried out during the dry season in a coffee field with a 40° slope in Topes de Collantes, Trinidad, Cuba, with the objective of assessing the allelopathic effects of Pinus caribaea on weed germination. A randomized block design with 5 treatments and 4 replicates was used. The treatments included the control (water) and treatment with glyphosate, grounded pine needles (58 g) and pine solution at 50% and 100% (58 g in a litre of water). In the plots, prepared in the coffee field using homogenized soil, the different treatments were applied 3 times and only water for the rest of the experiment to maintain the moisture. Application of glyphosate as control and the pine solution at 100% resulted in the control of weeds in the coffee field. Side effects of pine on the pH, microorganisms and mineral elements of the soil were not detected.
