Arvenses Asociadas a Los Cultivos De Naranjilla Y Tomate De Árbol

Abstract

En el cultivo de naranjilla y tomate de árbol, las arvenses presentes pueden ser hospederas de insectos parasitoides que permiten un control biológico natural de plagas. En este estudio se muestreó especies arvenses en las localidades de El Chaco (Napo) y Río Negro (Tungurahua) donde las familias encontradas mayoritariamente fueron Asteraceae, Poaceae y Cyperaceae.

Diversidad de la flora arvense presente en parcelas de pequeños agricultores, previstas para policultivos en cinco municipios de Boyacá

“…The Table 4 also show the variability in the indices: relative abundance (2.25%) and specific richness (3.16) in particular. Five (5) farms present equity indexes between 2 and 3.5 considered medium and 4 farms present dominance indexes lower than 0.17 considered as low [13].…”

“…In the municipality of Soatá, the farm with the highest relative abundance was El Gaque with 16.11% and the lowest was Copa de Oro with 2.78%. Four farms represented the highest number of species: La Palma (9), Ronquilla (6), Los Laureles and El Gaque (5). The Margalef diversity index obtained a maximum of 2.52 (La Palma) and a minimum of 0.62 in Copa de Oro.…”

“…When identified, ecological methods can be established for a good integrated management of unwanted plants, which in turn regulate and maintain environmental potentials in balance. Weeds have adaptations that allow them to survive in crop environments, and because of this they are considered dynamic colonizing plants that have a high reproductive capacity and effective interactions with other organisms in the agroecosystem [5].…”
