“…When asked whether or not soil fertility improvement should be added to the list of criteria, the farmers responded negatively. Our findings confirm the conclusions of Kitch et al (1998) who reported that in Cameroon farmers' acceptance criteria and preferences for cowpea varieties were strongly influenced by market preferences.…”

“…Participatory research has demonstrably improved the cultivar selection process [21,22]. In contrast, soil fertility methods are harder to disseminate because of the requirements of land, labor, and cash resources, with few successful models to follow [23].…”

Abstract:We conducted on-farm participatory experiments over three years at six villages in the Fakara commune of Western Niger to demonstrate, verify, and evaluate the relevance of soil fertility management methods based on millet/cowpea intercropping. We tested six methods using one of three organic fertilizers (millet husks, manure, or neither) with or without mineral fertilizer and one using millet/hibiscus intercropping with millet husks. We evaluated farmers' preferences by measuring the self-selected proportions of plots that farmers used for each condition. The results demonstrate the effectiveness of millet/cowpea intercropping; the application of mineral fertilizer, manure, and millet husks; and alternating-year application-all of them are affordable for farmers in the Sahel. Both the demonstration and farmerdirected trials made farmers aware of the effects of these methods. Farmers' selection of methods depended on availability. The dissemination of agricultural methods mainly depends on the availability of input materials in the absence of other constraints such as money and accessibility.

“…Two such trap crops against S. hermonthica are cotton (Sauerborn et al 2000) and cowpea (Gbèhounou and Adango 2003). Cotton and cowpea are also important (cash) crops in savannah regions of Africa (Kitch et al 1998), including north Cameroon. Cowpea, however, is susceptible to another species of Striga: Striga gesnerioides (Dubé and Olivier 2001).…”

Striga seed-germination activity of root exudates and compounds present in stems of Striga host and nonhost (trap crop) plants is reduced due to root colonization by arbuscular mycorrhizal fungi

Striga seed-germination activity of root exudates and compounds present in stems of Striga host and nonhost (trap crop) plants is reduced due to root colonization by arbuscular mycorrhizal fungi Abstract Root colonization by arbuscular mycorrhizal (AM) fungi reduces stimulation of seed germination of the plant parasite Striga (Orobanchaceae). This reduction can affect not only host plants for Striga, resulting in a lower parasite incidence, but also false hosts or trap crops, which induce suicidal Striga seed germination, thereby diminishing their effectiveness. In order to better understand these AM-induced effects, we tested the influence of root colonization by different AM fungi on the seed-germination activity of root exudates of the Striga hermonthica nonhost plants cowpea and cotton on S. hermonthica. We also tested the effect of AM fungi on the seed-germination activity of the Striga gesnerioides host plant cowpea on S. gesnerioides. Moreover, we studied whether mycorrhization affects the transport of seedgermination activity to above-ground plant parts. Mycorrhization not only resulted in a lower seed germination of S. gesnerioides in the presence of root exudates of the S. gesnerioides host cowpea but also seed germination of S. hermonthica was also lower in the presence of root exudates of the S. hermonthica nonhosts cowpea and cotton. Downregulation of the Striga seedgermination activity occurs not only in root exudates upon root colonization by different AM fungi but also in the compounds produced by stems. The lowered seedgermination activity does not appear to depend on the presence of seed germination inhibitors in the root exudates of mycorrhizal plants. The implication for Striga control in the field is discussed.
