題目：Land Use and Soil Management Challenges under Cocoa Production in Nigeria

要旨：
Cocoa (Theobroma cacao) was the mainstay of Nigeria's economy before the discovery of petroleum. Cocoa has a great potential to boost the economy of the country if given the needed policy attention. There is need to intensify cocoa production by increasing the cultivated land area and through increase in yield by rehabilitating old and non-productive cocoa plantation. Expansion of urban areas on agricultural lands, inherently infertile soil with low organic matter and cation exchange capacity, and soil nutrient depletion through pod harvest are the major challenges confronting cocoa production. The mandates of CRIN include improvement of agronomic practices in various cocoa growing ecologies in Nigeria. Recent soil fertility evaluation indicated that phosphorus is a major limiting factor across the country. Farmers are being sensitized to use fertilizer to replace the nutrients "mined" through pod harvest. Organic and organo-mineral fertilizers derived from cocoa pod husk have been developed as a substitute for the scarce and expensive inorganic fertilizers. For sustainable cocoa production and environmental protection, present research strategy focuses on the production of organic cocoa with minimal use of chemicals.
