At normal maturity the shells were commly infected althrough very few seeds were invaded. Fruits lifted when mature and dries in windows showed an increase in invasion of seeds. Seads from fruits picked shortly after liftning, then sun-dried on mats, showed little increase in fungal infection during drying, when fruits were left in the ground after reaching maturity, these was gradual increase of fungal invasion of the seeds. Macraphomina phaseoli and Fusarium spp were the dominant fungi in shells, these were also dominant in seeds of over mature and windrow-dried fruit. Aspergillus spp. Wer not abundant in shells or seeds but were frequently present, the toxigenic aspergillus flavus being the most common.

Public ISBD Titre de série : Samaru Research bulletin, 199 Titre : Lande tenure, land holding and agricultural development in the central Sokoto, close settled zone, Nigeria Type de document : texte imprimé Auteurs : Goddard, A. D. Année de publication : 1973 ISBN/ISSN/EAN : CI-05024 Note générale : A survey of land tenure in three villages in the central Sokoto close-settled zone shows that communal land tenure has given way under population presure and the influance of Muslin land low to individual handholding. This allows farmers considerable security of title encouraging land improvement, but does not allow land to be used as collateral for loans. Subdivision of holdings is encouraged by land low, and leads unders conditions of land shortage to diminishing size of holdings. But with capital a farmer may increase the size of this holding by purcharge or consolidate a fragmented holding. A relatively equitable distribution of land among the farming population could encourage the adoptation of innovations.
