Ferguson, John E.[Semilla de especies forrajeras tropicales : conceptos, casos y enfoque de la investigación y la producción : Reunión del Comité Asesor de la RIEPT]Semilla de especies forrajeras tropicales : conceptos, casos y enfoque de la investigación y la producción : Reunión del Comité Asesor de la RIEPT

The lack of good quality planting material of farmers' cassava varieties, produced locally and at low cost, is a major constraint limiting the expansion of cassava production in Colombia. This article describes the adaptation of conventional cassava propagation to a low-input scheme for rural tis...

Drawing on results of a survey of Ugandan farmers who previously hosted bean (Phaseolus vulgaris L.) varietal trials, this paper reports on the adoption of three new bush bean cultivars and assesses the usefulness of post-trial surveys as a methodology for obtaining reliable early feedback on var...

En épocas de lluvia (mayo de 2006) y de sequía (agosto de 2006), en tres sitios de la zona de ladera de los municipios de Bolívar, Sevilla y El Dovio, se evaluó mediante metodologías participativas el proceso de adaptación de tecnologías forrajeras. Se aplicaron evaluaciones abiertas, absolutas y...

Two sets of on-farm trials, each covering two years, were conducted in the northern Guinea savannah of Nigeria over the period 1999–2001, the objective being to compare integrated Striga hermonthica control measures (soybean or cowpea trap crops followed by maize resistant to Striga) with farmers...

This paper evaluates the utility of the `learning selection' model of the early adoption process, based on a constructivist conceptual framework, to explain farmers' adoption and rejection of two soil-improving technologies alley farming and the use of Mucuna cover crops. The analysis showed th...

In order to determine the improved soybean varieties that if recommended to the farmers would have a high probability of adoption, a farmer participatory approach was used to evaluate 12 soybean varieties at full podding in five locations (Oyani, Riana, Kasewe, Akiites, and Mabole) in western Ken...

The early adoption of the legume Arachis pintoi was studied in the State of Caquetá, located in Colombia’s Amazon region. Data came from 174 farmers randomly surveyed within the area of influence of Nestlé, a multinational milk-processing company. In addition, 52 farmers who had already adopted ...

Canavalia ensiformis, Crotalaria grahamiana, Dolichos lablab, Mucuna pruriens, Tephrosia vogellii and Tithonia diversifolia were evaluated as potential species for soil fertility replenishment in on-farm adaptive trials, farm visits and field days in Tororo District, eastern Uganda. Farmers used ...
