Resumen

MARTINEZ CAMPOS, Pedro et al. Weeds present in common bean crop (Phaseolus vulgaris) in intermediate sowing season and its influence on agricultural yield. Ctro. Agr. [online]. 2019, vol.46, n.3, pp.58-66. ISSN 2072-2001.

Research was carried out in the period from December 2017 to March 2018 in the "San José" farm, belonging to the Credit and Services Cooperative "El Vaquerito" of Santa Clara municipality, with the objective of recognizing the existing weeds in the common bean crop and its influence on agricultural yield in intermediate sowing season. The sowing of the cultivar "Milagro Villareño" took place on December 9, 2017, on a moderately washed soft Brown soil, in a randomized block design with three treatments and three replications. To determine the composition of the population of weeds, five samples were taken by the diagonal method. The indices of relative abundance and similarity of the weeds were determined. The harvest was made at 87 days after sowing, at which time 10 plants were randomly chosen by plot for a total of 30 for treatment, to which were evaluated: effective legumes per plant, effective seeds per legume and effective seeds per plant; as well as the mass of 100 effective seeds per treatments. Agricultural yields were also estimated in each treatment. The population of weeds was represented by 15 species, of which Echinochloa colona (L.) Link. and Portulaca oleraceae L. reached the highest values ​​of relative abundance. The highest agricultural yield was obtained when weed control was applied up to 60 days after the sowing.

Palabras clave : index of relative abundance; index of similarity; effective legumes; effective seeds.
