Resulta esencial calibrar las máquinas con el fin de lograr densidades de siembra y tasas de fertilización óptimas. Los errores en la calibración, incluso los más leves, pueden provocar grandes diferencias en el campo. Con la calibración se asegura que no se aplique demasiada semilla o fertilizante (con lo cual se ahorra dinero y se protege el medio ambiente), pero tampoco cantidades insuficientes, lo cual puede producir una disminución en el rendimiento.
This book is the re-titled third edition of the widely used Agricultural Extension (van den Ban & Hawkins, 1988, 1996). Building on the previous editions,Communication for Rural Innovation maintains and adapts the insights and conceptual models of value today, while reflecting many new ideas, angles and modes of thinking concerning how agricultural extension is taught and carried through today.
Este volante muestra cinco etapas para la modernizacion sustentable de la agricultura.
La presentación es dirigida a productores y grupos de personas, que realizan actividades agrícolas, pecuarias, acuícolas y pesqueras en zonas rurales y periurbanas. El documento da recomendaciones para facilitar el acceso de los productores familiares al acompañamiento técnico y trata de modelos de extensión con mayor impacto en el desarrollo de la Agricultura Familiar.
PESA focaliza sus acciones en “Apoyar a las Unidades de Producción Familiar en localidades rurales de alta y muy alta marginación, para incrementar los niveles de producción y productividad de sus actividades agropecuarias, acuícolas y pesqueras…”.
The paper explores the strength of social networks in the agricultural innovation systems (AISs) in Ghana and the effect of AISs on adoption of improved farm technology. The paper uses social network analysis (SNA) tools to identify, map and analyze the AISs and the two-stage Heckman selection model. Combining qualitative and quantitative methods allows testing the differential effects of social networks on technology adoption in the Ghananian Plantain Sector
The purpose of this article is to assess the inclusivity of on-farm demonstration across Europe, in relation to age, gender, and geographical location of participants. The paper is based on a survey of 1162 on-farm demonstrators (farmers and organisations) and three supraregional workshops. Overall, on farm-demonstrations were found to be engaging young(er) farmers who are at a career stage of being able to implement long-term innovations. However, across Europe demonstrations were primarily attended by men.
The latest comprehensive research agenda in the Journal of Agricultural Education and Extension was published in 2012 (Faure, Desjeux, and Gasselin 2012), and since then there have been quite some developments in terms of biophysical, ecological, climatological, social, political and economic trends that impact farming and the transformation of agriculture and food systems at large as well as new potentially disruptive technologies.
Agriculture faces an enormous global challenge of feeding nine billion people by 2050. This means a comprehensive intensification of agriculture is required. Ecological intensification is gaining momentum as a clearly defined vision for increasing agriculture productivity and sustainability. How ecological intensification could be tailored to benefit smallholder farming systems in sub-Saharan Africa (SSA) remains the major question. In this study, we develop pathways relying on ecological intensification technologies and suiting different farm types of smallholder agriculture.
This paper draws lessons from selected country experiences of adaptation and innovation in pursuit of food security goals.
