  2. Evaluación del crecimiento de un cultivo de clavel (dianthus caryophyllus) cv. delphi, establecido en diferentes tipos de sustratos

    Cala Gómez, Carlos Román; Guasca Beltrán, Marta Liliana
    Es necesario el uso de un sustrato adecuado para el cultivo de plantas ornamentales en horticultura intensiva, el cual se podría conformar con mezclas de diferentes materiales. En la sabana de Bogotá, limitantes físicas, químicas o sanitarias de los suelos estimulan la adopción de cultivos en sustrato, en particular, la alta incidencia de la marchitez vascular del clavel hace relevante esta practica. El presente trabajo se llevó a acabo en las instalaciones del Centro de Biotecnología Agropecuaria del SENA, ubicado en el municipio de Mosquera (Cundinamarca). Allí se estableció un cultivo de clavel estándar cv. Delphi, en un invernadero tradicional para flores de corte, al cual se le...

  3. Apple Tree Architecture and Cultivation - A Tree in a System

    Lauri, Pierre-Eric
    A majority of works developed in apple tree architecture and physiology in past decades are based on trees grown in monocultivar high density orchards. Here we propose to connect knowledge on the tree itself with knowledge on the system in which it is grown. In the two cases, scientific advances are intrinsically connected with practical aspects. It is first shown that although whole-tree shape variability presents a descriptive interest it is not strictly related to the fruiting pattern which is a major issue for apple cultivation. Architectural analyses have been developed not only to gain knowledge on the dynamics of...

  6. AusAgLCI - the business case for investment in a national life cycle inventory for horticulture

    Eady, S. J.; Grant, T.; Hercule, Jonathan; Deuter, P. L.
    Over the last decade there has been a significant focus on the environmental impact of products and services across the economy, resulting in environmental product declarations and delivery agreements where the supplier is required to demonstrate an on-going improvement program of environmental sustainability. Once action is required, primary producers need to be able to make an objective assessment of their overall environmental impact using Life Cycle Assessment (LCA), so that "hot spots" in their production system can be identified, and options to reduce these impacts can be investigated. Country-specific Life Cycle Inventory (LCI) for agricultural products is essential for Australian...

  12. El nuevo Régimen de Trabajo Agrario: Desajustes y propuestas de adecuación para el sector hortícola del periurbano bonaerense sur

    García,Matías; González,Edgardo
    El artículo se propone analizar el grado de ajuste y las formas de adecuación del Nuevo Estatuto del Peón (NEP) en la horticultura del sur del Gran Buenos Aires. Para ello, se identifican las modalidades de trabajo hortícola regional y se realiza un recorrido por las características más importantes del NEP. Esto posibilita indagar en la distancia entre lo normado y la práctica. Con estos insumos se discuten alternativas de adecuación de la ley. Se reflexiona que la legislación laboral y su cumplimiento son una política necesaria pero no suficiente para la problemática de la explotación del trabajador en un...

  13. Onion yield as affected by plant density, nitrogen level and loss of leaf area

    Siliquini,OA; Orioli,GA; Lobartini,JC
    Onion (Allium cepa) is an important horticulture crop because of its value as a food with a long shelf life being a relatively non-perishable product. It is very helpful to understand the growth response of the seeded onion crop to conduct appropriate field practices in attaining the highest or optimum yields. A three year field experiment was conducted using a variety of onion Valcatorce INTA, in a randomized block design with five replicates. Treatments were two plant densities and three rates of N application. The bulb growth followed a classical sigmoid curve. During the rapid growing period, the crop had...

  14. Factors influencing farmers’ willingness to participate in water allocation trading. A case study in southern Spain

    Giannoccaro, Giacomo; Castillo, Manuela; Berbel, Julio
    This study aims to uncover the factors that influence farmers’ attitudes towards water allocation trading. In the study, we simulate two water availability scenarios, an average year and a drought year, in a contingent valuation experiment with 241 farmers. A survey was held in the spring of 2012 in the Guadalquivir and Almanzora River Basins. First, we estimated a multinomial logit model to determine the factors that influence farmers to decide to participate in our hypothetical market. We then analysed the structural and socio-economic factors determining the monetary value of traded water using Heckman’s two-step model. Our results indicate that those farmers who are more...

  20. The long-term resistance mechanisms, critical irrigation threshold and relief capacity shown by Eugenia myrtifolia plants in response to saline reclaimed water

    Acosta-Motos, José Ramón; Hernández, José Antonio; Álvarez Martín, Sara; Barba-Espín, Gregorio; Sánchez-Blanco, María Jesús
    Salts present in irrigation water are serious problems for commercial horticulture, particularly in semi-arid regions. Reclaimed water (RW) typically contains, among others elements, high levels of salts, boron and heavy metal. Phytotoxic ion accumulation in the substrate has been linked to different electric conductivities of the treatments. Based on these premises, we studied the long-term effect of three reclaimed water treatments with different saline concentrations on Eugenia myrtifolia plants. We also looked at the ability of these plants to recover when no drainage was applied. The RW with the highest electric conductivity (RW3, EC = 6.96 dS m) provoked a...
