To the farmers, the introduction of more S. gesnerioides resistant cowpea varieties and possible introduction of Striga resistance into their local susceptible varieties could put them back in business as the devastating effects of S. gesnerioides were pushing most of them out of business. (iii)Farmers also called for assistance to improve upon the cultivation of cowpea as it is the major source of protein to most people in the region. [NAIROBI] Applying biochar, a charcoal-like substance made by burning plant waste matter as a fertilizer for growing cowpea could boost the crop’s growth and yield, a study in Ghana has found.. Cowpeas have substantial economic and health importance in Africa, where they provide food for people and livestock, as well as new crops. Despite the fact that SARI has released some Striga-resistant cowpea varieties, much effort is needed to make seeds available to farmers to cultivate. world; this region produces 64 % of the estimated 3 million tons of cowpea seed pro-duced annually. INTRODUCTION On the basis of area cultivated, cowpea is the most important food legume in Ghana. Once a field is invaded by S. gesnerioides, the underground S. gesnerioides seed stock will build up [18, 19], which sets up a situation of potential yield loss in the future [20].

However, the research institutions and the Ministry of Food and Agriculture need to collaborate with seed producing companies to multiply the existing S. gesnerioides resistant cowpea varieties and make them accessible to resource-poor farmers in all S. gesnerioides infested areas of Northern Ghana. /Annots [93 0 R] Cowpea does not necessarily need nitrogen fertilizer, but in cases whereby the land has been used continuously for farming purposes, application of starter dose of Nitrogen up to 20kg/ha is good, especially when the organic matter is as low as 1%. /Resources 82 0 R This could be attributed to the high illiteracy levels among the farmers in the region, as most of them have no or very little formal education. Symptoms displayed by cowpea due to S. gesnerioides infestation include premature leaf senescence, defoliation, chlorosis, necrosis, stunted growth, reduction in surface area of leaves, wrinkling of younger leaflets, poor flowering, or no flowering and fruiting at all [28]. %���� /WPS-ARTICLEDOI (10.1111/j.1470-6431.2010.00980.x) Out-scaling of quality seed of improved cowpea varieties.
