Nutritive Quality

The availability of high quality forage, especially during the dry season remains a major challenge to ruminant livestock production in Nigeria and many parts of West Africa. This study was conducted to evaluate forage yield and nutritive quality of haulm from selected dual purpose cowpea (Vigna unguiculata L. Walp.) cultivars in the humid rain forest zone of Nigeria. The forage and pod yields of twenty cultivars were evaluated at the Teaching and Research Farm of the Federal University of Technology, Owerri, Imo State, Nigeria. Subsequently, five dual-purpose cultivars, namely IT04K-334-2, IT07K-293-3, IT04K-194-3, IT04K-405-5, IT06K-147-2, were selected based on forage and pod yields from previous trial, for determination of chemical and fibre compositions. The results revealed significant (P<0.05) differences in pod and forage yields among the twenty cowpea cultivars, with yields ranging from 0-1.5 t ha-1 and 0.1-4.5 t ha-1 for pod and forage, respectively. Cultivars IT07K-293-3, IT04K-405-5, IT06K-147-2, IT07K-194-3, IT04K-334-2, IT04K-267-8 and IT04K-339-1 recorded the highest fodder yields of at least 2715 t ha-1, with crude protein contents ranging from 10.49% in IT07K-194-3 to 13 .57 % in IT04K-405-5. Cultivars IT07K-194-3, IT07K-293-3, IT07K-220-1-9, IT06K-147-2, IT07K-187-55IT04K-332-1 recorded the highest pod yields (>700 t ha-1). There were significant (P<0.05) differences in crude protein, ether extract and non-fibre carbohydrates (NFC) contents among five cultivars selected from the top ten high yielding cultivars, based on mean ranking score. These selected cultivars are recommended as dual-purpose cowpea for the humid forest zone.

AbstractChances and problems of forest management and afforestation in the humid forest zone of the Ivory Coast: Far-reaching changes in the forestry legislation since 1994 force the timber companies in the Ivory Coast to carry out afforestation measures for and with the local population in their concession areas. By the example of one of the first pilot projects the authors analyse the execution of reforestation at a village level. From the view of pedology they discuss the restrictions of possible afforestation measures in the adjacent areas of a national park

This paper analyses how macro-economic and agricultural policies, market fluctuations and demographic changes affected forests in the Humid Forest Zone of Cameroon in four periods between 1967 and 1997. For each period it examines how these variables influenced cocoa, coffee, food, and agroindustrial crop production and area, and logging. It concludes that government policies, market fluctuations and demographic changes all had a strong impact on forests. Pressure on forests increased after structural adjustment policies were initiated in the mid-1980s. Malthusian reasoning alone cannot explain the level of deforestation and forest degradation in Cameroon.
