Název v původním jazyce

Dynamics of weed species under different land use systems in Peruivan Amazon

Popis výsledku v původním jazyce

The objective of the study implemented in the Peruvian Amazon was to determine possible use of Inga edulis for control of weed species (e.g. Imperata brasiliensis). The study evaluates four treatments: (1) natural fallow; (2) cropping system with cassava; (3) planted fallow with Inga edulis; (4) planted fallow with I. edulis and kudzu. Weed biomass were measured at 3, 6, 9, 13 ,17, 20, 24, 28 and 32 months after fallow initiation. Weed samples were enumerated by counting the number of weeds by species in each subplot. About 20 most frequent weed species were determined. Highest frequency had I. brasiliensis; 185.1 individuals m-2 at three months and 31.4 individuals m-2 at 32 months (Inga + Pueraria). Aboveground biomass reached 180.9 g.m-2 at three months for Inga fallow. Results shows that all four treatments led to control of grass weed species. Because of the poor development of Inga trees on severally degraded soil, the trees could not suppress the weeds by shading.
