Comportamiento del cultivo del limón (Citrus aurantifolia Swingle) en "fincas tipo" en Santa Elena, Ecuador

Inglés. An investigation was carried out between August and November 2015 in order to understand the behavior of the lemon crop (Citrus aurantifolia Swingle) in "farm types" in the Province of Santa Elena, Ecuador. A "farm type" represents a group of farms with similar socio-economic characteristics. Four eightyears old "farms types" were selected. In each farm, 50plants were marked in which assessments were made. The trial did not have an experimental design but statistical analysis was done like a Completely Randomized Design (CRD), considering each farm type as a treatment and each plant as a replicate. The highest aphid (Aphis spp.) incidence was found in type I farms. Values were statistically different from type IV farms but similar to farm types II and III. The highest incidence of whitefly (Aleurothrixus floccosus), was found in type I farms that were statistically different from farm types III and IV. The highest incidence of sooty mold (Capnodium sp.), was found in type I farm that were statistically similar to other farms. The largest diameter and fruit weight, was found in farm type III with values that were statistically higher than farm types I and II but similar to farm type IV.

Español; castellano. Se realizó una investigación entre agosto y noviembre del 2015, con el objetivo de conocer el comportamiento del cultivo de limón (Citrus aurantifolia Swingle) en "fincas tipo" de la provincia de Santa Elena, Ecuador. Una "finca tipo" es representativa de un grupo de fincas con características socioeconómicas similares. Se seleccionaron cuatro "fincas tipos" con cultivo de limón de ocho años de edad. En cada finca se marcaron 50 plantas, en las que se hicieron las evaluaciones. El ensayo no tuvo un diseño experimental, pero el análisis estadístico se hizo como si fuera un Diseño Completamente al Azar (DBCA), considerando cada finca como un tratamiento y cada planta como una repetición. Se encontró que la mayor incidencia de pulgones (Aphis spp.) correspondió a la finca tipo I, estadísticamente diferente a la finca IV pero similar a las fincas II y III. La mayor incidencia de mosca blanca (Aleurothrixusfloccosus), correspondió a la finca tipo I, estadísticamente diferente a las fincas III y IV. La mayor incidencia de fumagina (Capnodium sp.), correspondió a la finca tipo I, pero estadísticamente similar a las otras fincas. El mayor diámetro y peso del fruto, correspondió a la finca III, estadísticamente mayor a las fincas I y II pero similar a la finca IV.
