Data on the vegetative response of cowpea to fertilizer application on three selected benchmark soils of the Upper West region of Ghana
Declining soil fertility among smallholder farmers in the Savannah zones of Ghana, among other issues, is triggered by continuous cultivation, low fertilizer use and low soil organic matter content. -
Combined application of inoculant, phosphorus and potassium enhances cowpea yield in Savanna soils
Low soil phosphorus levels in savanna soils of Ghana limit cowpea response to inoculation. A two-year experiment was carried out on 2 soil types of the Guinea and Sudan savanna zones of Ghana based on the hypothesis that Bradyrhizobia inoculant (BR3267) in combination with phosphorus and potassium fertilizer will significantly increase cowpea root nodulation, growth and yield. -
Nitrogen availability determines the long-term impact of land use change on soil carbon stocks in grasslands of southern Ghana
Enhancing the capacity of agricultural soils to resist soil degradation and to mitigate climate change requires long-term assessments of land use systems -
Mechanization, fertilization and staking options for environmentally sound yam production
An on-station study at Fumesua and Ejura in Ghana with two yam varieties (Pona and Dente), seedbed option (ridge and mound) and NPK fertilizer rates (0, 45-45-60, 60-60-60 and 60-60-80 kg ha-1 N-P205-K20) revealed significant (p < 0.05) increases in soil carbon and phosphorus with fertilizer application to yam. -
Economically optimal rate for nutrient application to maize in the semi-deciduous forest zone of Ghana.
Low inherent nitrogen (N), phosphorus (P), and potassium (K) contents of smallholder farms limit maize grain yield. Maize grain yield response to N, P, and K mineral fertilizer application and economically optimal rates for nitrogen (EORN), phosphorus (EORP ), and potassium (EORK) were evaluated on a Ferric Acrisol within the semi-deciduous forest zone of Ghana -
Soil and land Suitability Assessments towards Sustainable Rice Production in the Northern Zone of Ghana.
Rice has become the second most important cereal crop and a primary staple food in Ghana. However, domestic rice production falls below its demand, resulting in over 50% rice import per annum. -
Land Suitability Assessment and Landuse Planning: A Prerequisite for Food Security and Climate Change Adaptation
Though Ghana’s crop yield growth rate was at 17%, 5% of every 1.2 million Ghanaians have insufficient and limited access to nutritious food. Climate change and climate variability have enormously affected the state of agricultural productivity and hence could result in food insecurity. As many ongoing projects use Boolean suitability analysis, land use planning, management recommendations sores, it still remains inadequate to support rural resource poor farmers. This then, is affecting livelihood and agricultural productivity. In this paper, a geostatistical quantitative method to support a geographic information system (GIS) based on multi-criteria decision support system (GMCDSS) for an enhanced land suitability assessment (LSA) and landuse planning (LP) was devised.
