Impact of IITA germplasm improvement on maize production in West and Central Africa
(2003)The International Institute of Agriculture (IITA) is among the major suppliers of genetic materials to national agricultural research and extension systems in West and Central Africa for the development of improved maize varieties. This paper presents the results of a survey of the impact of germplasm from IITA on maize production and food security in 11 countries, which together contain over 90% of the area cultivated to maize in West and Central Africa. Between 1965 and 1998, the public sectors ... -
Mucuna fallow diffusion in southern Benin
(1999)Population pressure in the southern provinces of Benin has forced farmers to shorten or abandon the traditional bush fallow system. As a consequence, severe soil degradation and weed infestation constitute the most serious constraints to agricultural productivity. Mucuna fallow is one of the most promising technologies for natural resource management to restore soil fertility in intensified crop-ping systems. It was introduced in 1987 to some 15 farmers through farmers' participatory research in ... -
Collaboration to increase the use of Mucuna in production systems in Benin
In 1987, the leguminous cover crop Mucuna pruriens var. utilis was introduced on researcher-managed demonstration fields for novel technologies. The objective was to ad-dress the serious soil-fertility decline on the Adja Plateau in southern Bénin. But farmers were more impressed by the ability of Mucuna to control the rampant weed Imperata cylindrica and requested seeds to use for their own experimentation. However, a clear soil-fertility bonus became highly visible, and this aspect was further ... -
Production prospects for cassava in Tanzania: COSCA working paper, No. 16
Several cassava genotypes were observed although there were few bred varieties. The wide diversity in the cassava landraces was a consequence of the action of the farmers in continuously abandoning and introducing cultivars into their system as they tried to select those cultivars that met their needs. These included extended in ground storability in remote areas, high lOOt yield, and earliness in high demographic pressure areas, low cyanogen level in specific areas where the sweet cassava type ...
