This paper applies econometric analyses to quantitatively determine the individual risk attitudes of sampled maize farmers in the dry savanna zone of Nigeria. The extent of the risk attitudes are then made the basis for categorizing the farmers into three groups of low, intermediate and high risk...

Attitudes towards risk among maize farmers in the dry savanna zone of Nigeria: some prospective policies for improving food production
Eighty and sixty maize fields were sampled in 1994 and 1995, respectively, to monitor Aspergillus infection and aflatoxin contamination of preharvest maize in Benin. Three Aspergillus species were isolated from different agroecological zones, with A. flavus being the most prevalent. The countrywi...

A parasitic plant, Striga hermonthica (Del.) Benth., infests millions of hectares of arable land in sub-Saharan Africa, and it threatens production of major cereal crops including maize (Zea mays L.). Erratic natural infestation is considered a major constraint to assess host plant resistance to ...
Five maize genotypes differing in plant habit and growth period were evaluated at 5 population densities (10, 20, 40, 80 and 160 × 103 plants/ha) under an intercropping system with cassava at 1 × 1 or 1 × 0.67 m spacings in a tropical Alfisol in southern Nigeria. The 2-year study revealed signifi...
The palaeotropical, gregarious, endoparasitic braconids Cotesia sesamiae, Cotesia flavipes and Cotesia chilonis were recently imported into Benin as candidates for biological control of stem and cob borers of maize. Host acceptability and host suitability of six gramineous borers occurring in wes...

A fungal entomopathogen, Beauveria bassiana, was used to treat maize ears placed in traditional grain stores against Prostephanus truncatus in a field experiment conducted from September 1997 to March 1998 in the Benin Republic, West Africa. Treatments included oil-based spray with and without co...

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...
