<em>Pterocarpus erinaceus </em>Poir. is a tree species of the family Leguminonaseae distributed across West and Central Africa. The surging demand for its wood has hampered its natural regeneration in Nigeria. Effects of pre-sowing treatments and soil media on the germination of its seeds were examined using stratified random sampling. Seeds were sourced from Guineo-Sudanian savanna, Southern Guinea savanna, Derived/Guinea savanna and Northern/Southern Guinea savanna. Pre-sowing treatments including: water (27<sup>0</sup>C, 50<sup>0</sup>C, and 75<sup>0</sup>C for 8 hours, 16 hours and 24

Abstract. Chickens kept under free-range, backyard or semi-intensive systems in the developing countries have more diverse use and benefits to rural households. Their use varies from region to region and from community to community within a region. The study investigated growth, laying performance and survivability of six improved dual-purpose breeds in five agroecologies of Nigeria represented by the following states: Kebbi (Sudan savanna/northern Guinea savanna); Kwara (northern Guinea savanna/southern Guinea savanna); Nasarawa (southern Guinea savanna/derived savanna); Imo (lowland rainfore

In the savanna soil of Nigeria, micronutrient deficiency was not noticed in the past but with the intensification of agriculture over the years, crop exploitation of soil available nutrients, crop removal and adverse cultural practices of farmers have led to the incidence of micronutrient deficiency with negative effect on growth, yield and quality of crops. To enhance micronutrient availability, use and use efficiency to crops, a field experiment was set up on sorghum at Samaru in the Northern Guinea Savanna of Nigeria with foliar Algifol (Alg) nutrients solution and NPK.

AbstractThe Savanna Biomes (Mesic/Dystrophic and Arid/Eutrophic) of Angola cover over 90% of the country. This Chapter presents the case for the recognition, across Africa, of these two distinctive savanna biomes, both defined by the co-dominance of fire-tolerant trees and C4 grasses, falling within seasonal climates of warm, wet summers and mild, dry winters. The Mesic Savanna Biome occurs predominantly on the dystrophic (nutrient-poor) soils of the old peneplains of the Central African Plateau, mostly between 900 and 1400 m above sea level, and where rainfall ranges from 650 to 1400 mm per y

The in-situ measurements are from monitoring stations (at 10, 20, 30 cm depth) at two sites, Yendi and Jirapa in the Northern part of Ghana, West Africa. They are in two different sub-ecological zones of the Savanna in the North of Ghana. These sub-ecological zones are Western Sudan Savanna (Jirapa) and Open Guinea Savanna (Yendi).
