Phytosociology of weeds associated with rice crops in the department of Tolima, Colombia
Phytosociological studies allow for the characterization and descriptive analysis of weed communities in crops. This study aimed to characterize the weed communities associated with weed crops in the “Centro, Meseta, and Norte” zones of the Tolima Department. The study was conducted in 96 commercial...

This study aimed to characterize the weed communities associated with weed crops in the “Centro, Meseta, and Norte” zones of the Tolima Department. The study was conducted in 96 commercial lots, in which a 1 ha area was marked off for the sampling. The development stage, density and cover of the weeds were evaluated. The importance value index, the alpha diversity indices of Shannon-Wiener, Simpson and uniformity as well as the similarity indices of Jaccard, Sorensen and Steinhaus were calculated.
