Response of weeds and soil microorganisms to imazaquin and pendimethalin in cowpea and soybean

Autor: Chikoye, D. Abaidoo, R.C. Fontem, Lum. A.

Herbicides applied to combat weeds and increase crop yields may also have undesired effects on beneficial soil microorganisms. Field studies were conducted in 2005 and 2006 in Zaria, Nigeria, to evaluate the response of weeds and soil microorganisms to imazaquin applied at 0.05, 0.10, 0.20 an...

Safe re-use practices in wastewater-irrigated urban vegetable farming in Ghana.

Autor: Keraita, Bernard N. Abaidoo, R.C. Beernaerts, Ines Koo-Oshima, Sasha Amoah, Philip Drechsel, Pay Konradsen, Flemming

Irrigation using untreated wastewater poses health risks to farmers and consumers of crop products, especially vegetables. With hardly any wastewater treatment in Ghana, a multiple-barrier approach was adopted and safe re-use practices were developed through action research involving a number of ...

On-farm evaluation and determination of sources of variability of soybean response to Bradyrhizobium inoculation and phosphorus fertilizer in northern Ghana

Autor: Ulzen, J. Abaidoo, R.C. Ewusi-Mensah, N. Masso, C.

Soybean yields on smallholder farms in sub-Sahara Africa (SSA) are far below the potential yield thus creating a huge yield gap. Interventions are thus needed to bridge this yield gap and ascertain the factors influencing the yield variation. This study evaluated the on farm response of soybean t...

Population size, distribution, and symbiotic characteristics of indigenous Bradyrhizobium spp. that nodulate TGx soybean genotypes in Africa

Autor: Abaidoo, R.C. Keyser, H. Singleton, P. Dashiell, Kenton E. Sanginga, Nteranya

Soils of many potential soybean fields in Africa are characterized by low levels of biological nitrogen fixation (BNF) activities and often cannot support high soybean yields without addition of inorganic N fertilizers or external application of soybean rhizobia. The most probable number (MPN) te...

Organic acids in the rhizosphere and root characteristics of soybean (Glycine max) and cowpea (Vigna unguiculata) in relation to phosphorus uptake in poor savanna soils

Autor: Nwoke, O.C. Diels, J. Abaidoo, R.C. Nziguheba, Generose Merckx, R.

Root characteristics associated with phosphorus (P) uptake under limiting soil-P conditions were examined in two sets of greenhouse experiments. Average diameter and length of soybean, cowpea, maize and sorghum roots were assessed after 7 weeks in three low-P soils amended with P fertilizer at 0,...

Reducing health risks from wastewater use in urban and peri-urban Sub-Saharan Africa: applying the 2006 WHO guidelines

Autor: Drechsel, Pay Keraita, Bernard N. Amoah, Philip Abaidoo, R.C. Raschid-Sally, Liqa Bahri, Akissa

Where rapid urbanization is outpacing urban capacities to provide sound sanitation and wastewater treatment, most water sources in city vicinity are heavily polluted. This is of great concern as many of the leafy vegetables eaten raw in the cities are produced in these areas. Following the new WH...

Autor: Yusuf, A.A. Iwuafor, E.N.O. Abaidoo, R.C. Olufajo, O.O. Sanginga, Nteranya

Two crop rotation cycles were evaluated to determine the effect of cropping systems and N fertilization on the yield and efficiency of N in maize. Maize was grown on plots which had previously supported monocrops of two genotypes each of soybean (TGx 1448-2E and SAMSOY-2) and cowpea (IT 96D-724 a...
