The success of inland valley crop production in humid and subhumid areas of subSaharan Africa depends on the availability of appropriate crop varieties with some tolerance to excess moisture. Performance of upland crop associations [cassava (Manihot esculenta) + sweet potato (Ipomoea batatas) and...

Shoot-tips 15cm long from 15 soybean cultivars and breeding lines were individually immersed in Hoagland's solution in 1 × 14 cm test tubes, and supported by cotton plugs. All leaves were removed leaving about 1 cm of each petiole on the shoot. A 4 mm mycelial plug of Sclerotium rolfsii Sacc., ta...

Several legumes with high biological nitrogen fixation (BNF) potentials have been studied in on-station trials. The processes involved in BNF and the benefits of these species to crop production need to be evaluated using farmers' management practices in farmers' fields. An on-farm trial with 20 ...

The influence of soybean (Glycine max) planting date on seasonal epidemics of frogeye leaf spot caused by Cercospora sojina and on grain yield, was evaluated during the 1991 and 1992 cropping seasons. Two susceptible (Samsoy 1 and TGx 849-313D) and one resistant (TGx 996-26E) soybean cultivars we...

It has been difficult to explain the rotation effect based solely on N availability in maize-soybean cropping systems in the moist savanna zone of sub-Saharan Africa. Although arbuscular mycorrhizal fungi (AMF) can contribute to plant growth by reducing stresses resulting from other nutrient defi...

Grains of nine soybean varieties were processed into soybean milk, and their milk yield and protein (%) were determined, followed by sensory evaluations. In another experiment, grains of five soybean varieties were made into soybean milk, using five different processing techniques. In the first e...

Red leaf blotch, caused by Dactuliochaeta glycines (R.B. Stewart) Hartman & Sinclair (2) (= Pyrenochaeta glycines R.B. Stewart), was observed on soybeans (Glycine max (L.) Merr.) at Bukuru, near Jos in the state of Plateau, Nigeria, in 1990. Over 80% of the plants in the 4¬ha nonirrigated, sandy ...
