(Corporación Colombiana de Investigación Agropecuaria (Agrosavia), 2013-05-24)
Tahiti lime, Citrus latifolia Tanaka (Rutaceae), is susceptible to Citrus Tristeza Virus (CTV), and if affected, decreases the profitability of the crop. In the well-drained high terrace of the Meta piedmont, the influence of the virus attack was evaluated on the performance of Tahiti lime grafted on six rootstocks(Carrizo; Sunki × English; Sunki × Jacobson; Pomeroy; Rubidoux, y Kryder 15-3) on a completely randomized ...

This article establishes the financial viability for the production and export of gulupa (Passiflora edulis Sims) to the Spanish market, including environmental, technical and economic elements. Several alternatives are presented for gulupa production, the marketing process and export to Spain, based on descriptive and exploratory methods that involved the characterization, identification and situational analysis. ...
Alternate bearing and phenology of ‘Valencia’ orange (Citrus sinensis [L.] Osbeck) in the lowland wet tropics of ColombiaAlternancia de la producción y comportamiento fenológico de la naranja ‘Valencia’ (Citrus sinensis [L.] Osbeck) en el trópico bajo húmedo de Colombia
(Corporación Colombiana de Investigación Agropecuaria (Agrosavia), 2013-01-17)
In tropical conditions near the equatorial, precipitation is the main climatic factor that influences the growth and development of citrus plants. In a ‘Valencia’ orange orchard planted with 11-year-old trees located in the higher portion of the foothills of Corpoica, La Libertad Research Center in Villavicencio, Meta, Colombia, we recorded tree production data between the years 2008-2010. Information on the phenology ...
Determination of safe storage under controlled for rootstock seed of ‘Tahiti’ limesDeterminación de condiciones controladas de almacenamiento seguro para semillas de portainjertos de lima ácida ‘Tahití’
(Corporación Colombiana de Investigación Agropecuaria (Agrosavia), 2013-01-17)
One of the disadvantages in agricultural production is the adequate and timely supply of seeds. The absence of controlled storage methods of citrus seeds in nurseries is the main limiting factor for the production of planting material, because 40% of this material is lost through poor physiological quality of the seeds. The objective of this study was to determine the best conditions for storing seeds of CPB Citrumelo ...
Diagnosis of chemical soil fertility of the municipalities of Granada and Silvania for golden cape gooseberry production in CundinamarcaDiagnóstico de la fertilidad química de los suelos de los municipios de Granada y Silvania para la producción de uchuva en Cundinamarca
(Corporación Colombiana de Investigación Agropecuaria (Agrosavia), 2013-01-17)
Adequate plant nutrition is essential to get high crop yields and good export quality for the cape gooseberry. In order to characterize the chemical fertility of soils of cape gooseberry producing areas in Cundinamarca, samples were taken in two major producing municipalities, Granada and Sylvania. To this end, we selected 30 farms for soil sampling and subsequent chemical characterization and determination of the ...
Management of Neohydatothrips signifer Priesner (Thysanoptera: Thripidae) in yellow passion fruit (Passiflora edulis f. flavicarpa Degener) at the Huila region (Colombia)Manejo de Neohydatothrips signifer Priesner (Thysanoptera: Thripidae) en maracuyá (Passiflora edulis f. flavicarpa Degener) en el departamento del Huila (Colombia)
(Corporación Colombiana de Investigación Agropecuaria (Agrosavia), 2012-06-08)
Thrips are the main pest of the yellow passion fruit, with a potential of up to 95% damage in vegetative terminals. conventional management for this pest is focused on the use of chemical insecticides, restricting export of the fruit. This research looked at a model of integrated pest management (IPM) for thrips in cultivated passion fruit on three farms in the municipality of La Plata (Huila). There were two plots; ...
Morpho-agronomic and molecular characterization of the ‘Arrayana’ mandarin in the piedmont of the Meta department (Colombia)Caracterización morfo-agronómica y molecular de mandarina ‘Arrayana‘ en el piedemonte del Meta (Colombia)
(Corporación Colombiana de Investigación Agropecuaria (Agrosavia), 2012-06-08)
Due to the absence of varietal information for the tangerine (Citrus reticulata L.) ‘Arrayana’ in the piedmont plains of Meta (Colombia), morpho-agronomic and molecular characterization of 10-year-old commercial tangerine trees was carried out at the Research Center La Libertad of Corpoica in Villavicencio (Meta). Descriptors suggested by the International Genetic Resources Institute (IPGRI) were used for the morphological ...
Integrated pest management as a strategy to control the passionfruit flower-bud fly, Dasiops inedulis Steyskal (Diptera: Lonchaeidae)Manejo integrado de plagas como estrategia para el control de la mosca del botón floral del maracuyá Dasiops inedulis Steyskal (Diptera: Lonchaeidae)
(Corporación Colombiana de Investigación Agropecuaria (Agrosavia), 2012-06-08)
Four parasitoids of the passion fruit flower bud fly, Dasiops inedulis Steyskal (Diptera: Lonchaeidae) were collected in the present study, i.e., a larva-pupa type parasitoid, Utetes anastrephae (Viereck) (Hymenoptera: Braconidae), and three pupal parasitoids, namely Pachycrepoideus vindemmiae Rondani, Spalangia sp. (Hymenoptera: Pteromalidae) and Aganaspis sp. (Hymenoptera: Figitidae). In the field we observed a species ...
