Delta traps baited with maize cobs, which were infested each with one male Prostephanus truncatus (Horn) (Col.: Bostrichidae), were distributed in southern Benin and collected after one, two, three and four weeks. The numbers of P. truncatus caught during the different trapping periods were not s...

Maize is the most important cereal in sub-Saharan Africa. It is relatively inexpensive and provides many families with much-needed nutrients. For the farmers, it matures early and Is a source of ready income. Maize production Is being threatened by some diseases and pests, among which are downy m...

A two year trial was conducted a11badan to determine the effects of okra and melon on the soil moisture and leaf water status of cassava/maize intercrops. Inclusion of melon into a cassava/maize mixture. Especially where the cassava had sparse canopy, appeared to be an effective means of conservi...

During routine surveys conducted from February to July 2015 in the northern guinea savannah
region of Nigeria, sugarcane and itch grass (Rottboellia cochinchinensis) plants showing virus-like
mosaic symptoms were encountered in farmers’ sugarcane fields in Kaduna State. Symptomatic

Two field experiments were conducted during the 1993 and 1994 growing seasons at Samaru (7° 38' E; 11° 11' N), northern Nigeria, to evaluate N-use efficiency (kg grain per kg available soil N) and yield of 5 maize genotypes planted early in the season under five levels of N. The hybrid (8644-27) ...

The type and level of disease reaction of Ugandan maize genotypes to Peronosclerospora sorghi was characterized using several variables during the second season of 1994 at two locations, Nazaretti in Mpigi district and Ikulwe in Iganga district. Maize genotypes differed significantly (p 0.05) in ...

Biotic constraints (insects, diseases, parasitic weeds) and abiotic stresses (drought) are widespread and pose a constant threat to maize production worldwide. Tropical environments provide the greatest opportunity for evolution of insects and diseases because of the favourable year- round climat...

Field data have suggested that under P-deficient conditions, legumes supplied with phosphate rock (PR) increase P acquisition by a subsequent maize crop compared to direct application of PR to maize. This study assessed the mechanism of this positive rotational effect in terms of soil P availabil...

In Uganda, nematodes have the potential to cause substantial yield losses, yet it is not known whether farmers have knowledge of the damage these pests cause. A participatory rural appraisal was therefore conducted to assess farmers' awareness of nematodes, and to determine the preferred traits i...
