The experiment was carried out using a replicated (3x3) Latin square design with six sheep, to assess, the effect of supplementing maize stover fed ad libitum at three levels (100, 150 or 200 g) of Leucaena diversifolia. The sheep had an initial live weight of 26.4 kg (+ or -) 1.78 kg. In each pe...

Maize (Zea mays L.) cultivars combining high grain yield with elevated levels of lysine, tryptophan, and desirable endosperm modification, could reduce food insecurity and malnutrition in West and Central Africa (WCA). Sixteen early- and nine extra-early-maturing quality protein maize (QPM) and n...

A study was conducted to evaluate the use of different intra-row spacing to optimize Striga infesta- tion for resistance screening in maize. Five maize geno- types of different genetics backgrounds and contrasting reactions to Striga hermonthica were evaluated under four intra-row spacing. The ex...

This study was conducted to evaluate the yield performance of different maturity groups of maize varieties at different planting dates under the marginal rainfall conditions of the rainforest ecology of Nigeria and identify the high yielding ones. The maize varieties were evaluated on five and th...

In the Republic of Benin, the scelionid egg parasitoid Telenomus isis (Polaszek) is one of the most important control factors of the noctuid maize stem borer Sesamia calamistis. In the present study, the role of various sources of contact kairomones (male or virgin or mated female moths) and of t...
Maize is an important food crop in the Guinea savannas of Nigeria where it is gradually replacing the traditional cereal crops, such as sorghum and millet because of its high productivity. Despite its high yield potential, maize production is faced with numerous constraints. One of these Is droug...

The effects of a new formulation of atrazine for weed control in maize were studied during the wet season of 2002 and 2003 at Ibadan, Nigeria. The treatments were the new formulation at doses from 1.0 to 3.5 kg a.i./ha and the old formulation at the recommended dose of 3.0 kg a.i./ha. Untreated a...
