1. Evaluación de sustratos en un cultivo de lechuga bajo un sistema hidropónico en el municipio de Pasto - Guerrero, Elizabeth Marcela; Revelo, Juan Camilo; Benavides, Orlando; Chávez, Germán; Moncayo, Carlos Álvaro
Horticulture is a strong economic line in Nariño; this project was done as an alternative to improve the production and quality of lettuce. The evaluation of coconut fiber and rice husks substrates for a hydroponic A-frame structure system for the production of lettuce (Lactuca sativa L.) was carried out at the International Center for Clean Production Lope, SENA Regional Nariño. A total of 200 plants were cultured in an area of 10 square meters, from which plant height, diameter, total weight, and head and root weight variables were evaluated. An unrestricted random sampling design with 5 treatments and 4 replicates was performed, where treatment 1 corresponded...

2. Caracterización de isopodos terrestres (Crustacea: Isopoda) y su impacto en cultivos hortícolas de Boyacá - Martínez O., Wilson; Pérez Camacho, Fernando; Espíndola, Carmen Cecilia
Terrestrial isopods (Crustacea: Isopoda) have been arising as important agricultural pests in countries such as Brazil and Argentina, where they are harmful to soybean, sunflower, and pastures. Recently, they have been found in Boyacá, affecting onion and bean plants and fruits. According to this, it was necessary to initiate species’ characterization and establish their impact to horticulture in some municipalities in the region. A survey at Paipa, Tibasosa, Nobsa, and Santa Rosa de Viterbo was conducted to determine the presence and diversity of terrestrial isopod species; in addition, a questionnaire was carried out in order to establish farmers’ perceptions of crustacean damage and management strategies. Eight localities...

4. Estudio de la influencia del injerto en pimiento (Capsicum spp.) frente a estrés salino - DOMINGO CALAP, MARÍA LUISA
[EN] Salinity is one of the biggest environmental problems in horticulture. Grafting is presented as a sustainable and respectful technique with the environment. The grafting implementation as an alternative goes through the selection of a good combination of rootstocks and varieties with a good adaptation to stress conditions, in this case salt stress, with an optimum production and quality. In this work, 6 combinations of pepper genotypes (Capsicum spp.) were analyzed: the commercial variety Adige, the accessions A5 and A7 and the graft of the cultivar variety onto itself, as well as onto each of the rootstocks used. These genotypes were studied both, in the germination phase and...

5. Formation et répartition des gains de productivité dans l'agriculture française : analyse par produit - Butault, J.P.; Delame, N.; Rousselle, J.M.
Cet article analyse la formation et la répartition des gains de productivité pour quelques grands secteurs de l'agriculture française (céréales, horticulture, arboriculture, productions herbivore et granivore), entre 1979 et 1991. Des comptes par produit sont d'abord établis, à partir du Réseau d'information comptable agricole (RICA). Sont calculés, ensuite, des indices de prix et de productivité pour ces différents secteurs et la méthode des comptes de surplus est appliquée. L'étude montre, qu'autant dans leur formation des gains de productivité que dans leur répartition, les situations sont très différentes selon les secteurs. Elle montre notamment les relations entre le secteur des céréales...

14. Análisis del ciclo de vida aplicado a la horticultura protegida - Antón Vallejo, M. Asunción
This chapter provides a description of the environmental tool Life Cycle Assessment, LCA, focused on their use in horticulture. According to ISO standardisation guidelines a LCA study can be divided into four steps: goal and scope definition, inventory analysis, impact assessment, and interpretation. Each one of these steps is analysed. Then follows a review of major studies conducted to date, which use this tool in the environmental assessment of greenhouse production. It ends with a conclusion which highlights the main environmental problems in Mediterranean greenhouses arising from these studies. In addition methodological issues of the environmental tool, LCA, which require...

15. Greenhouse climate control in mediterranean greenhouses - Kittas, Constantinos; Katsoulas, Nikolaos; Bartzanas, Thomas
An overview of the good agricultural practices for greenhouse horticulture in the Mediterranean and South East Europe regions is presented and discussed. In these areas, natural ventilation and whitewashing are the most common methods/systems used for greenhouse climate control during summer, since it require less energy, less equipment operation and maintenance and are much cheaper to install that other cooling systems. However, generally these systems are not sufficient for extracting the excess energy during sunny summer days and therefore, other cooling methods such as forced ventilation combined with evaporative cooling (mist or fog system, sprinklers, wet pads), are used. On...

16. Comportamiento de líneas de Cucumis metuliferus, Citrullus lanatus var. citroides y C. colocynthis frente a Meloidogyne spp. como potenciales portainjertos de melón, pepino y sandía - Munera Giménez, María; Giné Blasco, Ariadna; Pocurull Domènech, Miriam; Picó Sirvent, Belén; Gisbert Doménech, Carmina; Sorribas Royo, Francisco Javier
La resistencia vegetal para el control de Meloidogyne es efectiva y económicamente rentable, pero su uso continuado puede seleccionar poblaciones virulentas, como se ha citado en tomate y pimiento. En cucurbitáceas existe germoplasma resistente que podría utilizarse como patrón en rotación con solanáceas para mejorar el control del nematodo y la durabilidad de los genes implicados. Se llevaron a cabo una serie de ensayos para identificar resistencia a M. incognita y M. javanica en dos líneas de Cucumis metuliferus

17. Arqueología de cazadores recolectores del sector centro-oriental de la región pampeana - Loponte, Daniel; Acosta, Alejandro
The wetland located in the Central-East of the Pampean region, associated with the Parana and Rio de la Plata rivers, shows a complex archaeological record, dated between 1640 and 680 YBP, suggesting an important concentration of hunter-gatherers population. The production of non transportable equipment like pottery, the use of bipolar reduction and selectivity of preys belonging to the wetland, suggest a low mobility and small home ranges. Fishes are the main prey in all the sites placed in the wetland. The arrival of Amazonian horticulture groups, probably increased significantly the social complexity of the area.

18. Factores relacionados con la adopción de buenas prácticas agrarias en horticultura. Aplicación de un índice de adopción agregado a la horticultura bajo abrigo del litoral granadino - Bertuglia, A.; Calatrava, J.
t is increasingly common among farmers the adoption of good agricultural practices (GAP). Considering protected horticultural production, these practices can be of various kinds. This paper is based on a survey of growers in the western coast of Granada. From the information obtained an aggregate adoption index has been performed, and the relationship between this index and some of the structural characteristics and farm management as well as some entrepreneurs sociocultural variables (age, level of study, agricultural training, etc..) has been analysed and discussed. This analysis identifies variables related to the adoption of GAP, and finally allows to consider possible...

19. PRODUÇÃO de erva-mate em sistemas arborizados: programa 18: Sul.
Cultura de base familiar, a erva-mate é explorada em cerca de 180 mil propriedades distribuídas por mais de 500 municípios dos estados do Paraná, Santa Catarina, Rio Grande do Sul e Mato Grosso do Sul. Movimenta uma diversificada cadeia de produção, que inclui chás, e outras bebidas, cosméticos, medicamentos, além do tradicional chimarrão. Já a arborização é uma prática agroflorestal que pode ser aplicada em qualquer tipo de sistema de produção: grãos, pastagens, fruticultura, horticultura e outros. Conforme esclarece o pesquisador da Embrapa Florestas, Amilton Baggio, arborização não é sombreamento e, sim, o consórcio da cultura agrícola com um pequeno...

20. Información y redes sociales en la conformación de mercados de trabajo - Benencia, Roberto
En este trabajo nos interesa destacar el papel de las redes sociales y la información en la conformación de los mercados de trabajo, tomando como ejemplo la inserción de inmigrantes bolivianos en la horticultura de la Argentina, y apelando al concepto de instituciones estructurantes de los mercados de trabajopropuesto por Ludger Pries (2000), para entender su construcción.
