Does incorporation of cowpea-maize residue mixes inﬂuence nitrous oxide emission and mineral nitrogen release in a tropical luvisol?

Frimpong, K. A.; Yawson, D. O.; Baggs, E. M.; Agyarko, Kofi (University of Cape Coast, 2011-10-13)

In the face of climate change, quantiﬁcation of the emission of nitrous oxide from soils in relation to sufﬁcient N availability for crop uptake has assumed much signiﬁcance. This study used the 15N stable isotope technique, ...
Incidence and severity of maize streak disease: The influence of tillage, fertilizer application and maize variety

Blankson, D.; Asare-Bediako, E.; Frimpong, K. A.; Ampofo, E.; Taah, K. J.; Puije, G. C. Van der (University of Cape Coast, 2018-02)

Maize streak disease (MSD) is one of the most destructive diseases of maize (Zea mays L.) estimated to cause a yield loss of about 20% in Ghana. Field experiment was conducted at Nkwanta in the Volta Region of Ghana during ...
Nitrous oxide emissions from soils amended with polyphenols and cowpea residues

Frimpong, K. A.; Yawson, D. O.; Adu, M. O.; x Baggs, E. M. Baggs (University of Cape Coast, 2014)

Polyphenols can influence the rate of N2O emission and N mineralization in leguminous crop residues by affecting the activities of residue decomposers or by forming protein complexes. A laboratory microcosm incubation study ...
Plant litter turnover, soil chemical and physical properties in a Ghanaian gold- mined soil revegetated with Acacia species

Frimpong, K. A.; Afrifa, E. K.A.; Ampofo, E. A.; Kwakye, P. K (University of Cape Coast, 2014-04)

The effects of stand-age of Acacia sp on plant litter turnover and decomposition, soil physical properties and nutrient elements were studied in revegetated gold-mined soils. Litter in the 3- and 6-year plantation soils ...
Plant litter turnover, soil chemical and physical properties in a Ghanaian gold- mined soil revegetated with Acacia species

Frimpong, K. A.; Afrifa, E. K.A.; Ampofo, E. A.; P. K, Kwakye (University of Cape Coast, 2014-04)

The effects of stand-age of Acacia sp on plant litter turnover and decomposition, soil physical properties and nutrient elements were studied in revegetated gold-mined soils. Litter in the 3- and 6-year plantation soils ...
Relationships Between Potassium Forms and Selected Physico-Chemical Properties Of Some Ghanaian Soils Along A Topo sequence

Amoakwah, E.; Frimpong, K. A. (University of Cape Coast, 2013-07-07)

A study was conducted to determine the distribution of forms of K (water soluble K, exchangeable K, non-exchangeable K, and total K) of potassium in some Ghanaian soils occurring along toposequence using standard laboratory ...
Sweet potato (Ipomoea batatas) yield parameters, soil chemical properties2 and cost benefit ratios following incorporation of poultry manure and inorganic3 NPK fertilizers in low nutrient Ghanaian soils

Agyarko, K.; Dapaah, H. K.; Buah, S.; Frimpong, K. A. (University of Cape Coast, 2012)

The impact of sole poultry manure (6t PM ha-1), sole NPK (200kg NPK ha-1) and their combinations (3t PM + 100kg NPK ha-1 and 1.5t PM + 150kg NPK ha-1) on sweet potato yield parameters and soil nutrients was assessed at ...
