Weather-sensitive agricultural operations in groundnut production: the Nigerian situation
1986
Yayock, J.Y. | Owonubi, J.J.
shGroundnut production is currently confined largely to the Sudan and northern Guinea savanna zones in Nigeria, and is dependent on the availability of rain water, matching the crop-growth cycle to the length of the growing season, as well as the seasonably variable sunlight and temperature regimes. Agronomic operations and effective management practices are oriented towards the prevailing weather conditions in production areas. The recent downward trend in the total annual rainfall and the reduction in the length of the rainy season have necessitated a southward production trend. There are many implications of this shift: the need to match resistance or at least tolerance to the major insect pests and diseases of the wetter and more humid Guinea savanna; devising ways to alleviate the inevitable problems of lifting if the crop remains unharvested up to the end of the rainy season; devising ways to efficiently dry the crop if it is lifted before cessation of rains; and the need for efficient handling of the produce in order to ensure high kernel quality devoid of contamination, especially aflat
