- Abstract
The presence of weeds in "coffee" Coffea arabica (Rubiaceae) cultivation is one of the factors that limit its sustainability. Therefore, studies in floristics and ecology are necessary for the design of integrated management programs. This research work was carried out between April 2017 and April 2018, with the objective of studying the change in the coverage of weeds associated with coffee cultivation in the central jungle of Peru. Samples were taken from the community of weeds in coffee farms in the districts of San Ramón, Pichanaki and Villa Rica, placing five squares (1 m x 1 m), randomly distributed in each farm. During the months of evaluation, all species found within the squares were taxonomically identified and vegetation cover and diversity indices were evaluated. A total of 42 weed species were identified, the most numerous families being Asteraceae (12 species) and Poaceae (5 species) and the species with the highest percentage of cover were: Cyathula achyranthoides (Kunth) Moq. (San Ramón), Digitaria swalleniana Henrard (Pichanaki) and Stellaria media L. (Villa Rica). The Villa Rica plot was the most diverse, presenting a diversity index of Shannon-Wiener (H') = 2.06, higher than San Ramón (1.55) and Pichanaki (1.28).
