Adoption of two new potato varieties in Cameroon: Progress and constraints

In 1992, two potato varieties, Cipira and Tubira, were released in Cameroon by IRAD-CIP, a cooperative project between Cameroon and the International Potato Center. From 1993 to 1997, more than 31 tons of sprouted potato basic seed from these varieties were distributed to farmers. In 1998, a study was carried out in the main potato-producing region of Cameroon to characterize the progress and constraints faced by potato farmers in adopting the new potato varieties. Data were collected through a survey of 297 farmers using stratified random sampling. These data, analyzed using descriptive and student statistics, indicated that 98.6% of the potato farmers were aware of the new cultivars. Their main source of information was other farmers (51.5% of farmers informed). Seventy-eight percent of the farmers were still using Cipira and 62% had adopted it as part of their production system. These farmers (62.6%) reported that the resistance of Cipira to late blight was higher than that of local and European cultivars. The farmers’ average yearly potato production increased from 1.6 to 3.1 tons during the period when these varieties were being adopted. The main constraint to the adoption of Cipira and Tubira was bacterial wilt susceptibility. About 59% of the potato farmers complained of this constraint. Another major problem was the lack of technical guidance for potato farmers from the Cameroon Agricultural Extension Service, from which only 27.3% of the farmers received information. Because of these constraints, 3% and 7.4% of the farmers had already abandoned Cipira and Tubira, respectively.

Dos variedades de papa, Cipira y Tubira fueron liberadas en 1992 en Camerún por IRAD-CIP, un proyecto cooperativo entre Camerún y el Centro Internacional de la Papa. De 1993 a 1997 se distribuyó a los agricultores más de 31 toneladas de semilla básica de papa brotada de estas variedades. En 1998 se llevó a cabo un estudio en la principal region productora de papa de Camerún para determinar el progreso y los problemas afrontados por los agricultores al adoptar las nuevas variedades de papa. Los dates se colectaron a través de una encuesta entre 297 agricultores utilizando muestreos estratificados al azar. Estos datos, analizados utilizando estadística descriptiva y de estudio, indicaron que el 98.6% de productores de papa estaban informados sobre los nuevos cultivares. Su principal fuente de información fueron otros productores (51.5%). El 78% de los agricultores estaba todavia usando la variedad Cipira y el 62% la habia adoptado como parte de su sistema de producción. Estos agricultores (62.6%) dieron cuenta de que la resistencia de Cipira al tizón tardío fue superior a la de los cultivares local y europeo. El promedio de producción anual de los agricultores se incrementó de 1.6 a 3.1 tons durante el periodo en que estas variedades estaban siendo adoptadas. El principal inconveniente para la adopción de Cipira y Tabira fue la susceptibilidad de estas variedades a la marchitez bacteriana. Alrededor del 59% de los productores de papa se quejaron con respecto a este inconveniente. Otro problema importante fue la falta de dirección técnica para los productores de papa del Servicio de Extensión Agrícola de Camerún, de los cuales sólo el 27.3% recibieron información. Debido a estos inconvenientes, el 3% y el 7.4% de los agricultores ya ha abandonado el cultivo de Cipira y Tubira respectivamente.
