A multi-location study was conducted to assess the nitrogen (N), phosphorous (P) and potassium (K) requirements of lowland rice (Oryza sativa L.) for a local variety Digang cultivated in the northern Savannahs of Ghana and offer site specific nutrient recommendations. Ten on-farm nutrient omission trials involving five rates of N, P and K combinations were conducted during 2010 cropping season in Sudan and Guinea Savannah agro-ecological zones. The treatments (kg/ha as N, P2O5 and K2O) comprised 0-0-0 (control), 0-90-90 (zero N), 90-0-90 (zero P), 90-90-0 (zero K), 90-90-90 (NPK). Grain yields

Streszczenie:

Australia and New Guinea (together referred to as Sahul) were linked by land for much of the late Tertiary and share many biotic elements. However, New Guinea is dominated by rainforest, and northern Australia by savannah. Resolving patterns of biotic interchange between these two regions is critical to understanding the expansion and contraction of both habitat types. The green tree frog (Litoria caerulea) has a vast range across northern and eastern Australia and New Guinea. An assessment of mitochondrial and morphological diversity in this nominal taxon in New Guinea reveals two taxa. True

Nigeria has diverse ecological conditions, ranging from mangrove swamp of the southern coastal regions to the derived Savannah of the middle belt and the Sudan/Guinea Savannah of the Northern part of the country. Using the southern wet humid rainforest condition of NIHORT, Ibadan, two germplasm evaluation trials were carried out during the rainy season of May to Sept. 1996 and 1997. Thirty-nine tomato accessions were investigated on 1 × 4-m plots at 50 x75-cm spacing in a completely randomized block design with three replications. The top 10 and the least 10 accessions were evaluated for yield

This study examined the adoption of improved maize varieties in northern Guinea Savanna of Borno State. Primary data were collected by using structured interview schedule. Two hundred maize farmers were systematically selected from. Percentage and logit were used for data analyses. Overall adoption rate was 89.0%. Coefficient of socio-economic and institutional factors such as extension contact (0.0360), farm size (0.2319), education level (0.0460), access to credit (0.6363) and age (0.7619) were found to be significant (P≤0.01) and positively influencing adoption of improved maize varieties.

Indigenous guinea fowl is an important animal resource for improving rural household income. In order to provide molecular data for a sustainable management of this poultry resource, an assessment of the genetic diversity and phylogenic relationships was undertaken on seven guinea fowl phenotypes from two agroecological zones (Dry Savannah and Atakora) of Togo. Genotyping was carried out using 18 microsatellite markers on 94 individuals from Dry Savannah (59) and Atakora (35) zones. The results obtained showed a high genetic diversity, with six as an average alleles per locus and an observed h

Abstract The West African Dwarf (WAD) goats have hereditary dwarfism and are adapted to the humid climate. The study compared the cold tolerance of WAD and Savannah (Red Sokoto and Sahel) goats during the peak of the West African cold season in the Northern Guinea Savannah of Nigeria. A total of 18 adult non-pregnant, dry does comprising equal number of each breed (six per breed) were used for the study. Thermoregulatory variables were recorded four times in the morning (07:00 h) and afternoon (13:00 h) hours at two-day intervals. Results revealed that irrespective of the hour of day, the WAD

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
