Journal Article 2012-09

Autor: Ajala, S. Kling, J. Menkir, A.

Improving maize productivity in the savannas of West Africa will depend on improving soil fertility and ensuring the efficient use of inputs and the relevant maize varieties tolerant to low nitrogen (N) that have been developed for this region. Several cycles of full-sib family selection that com...

Maize (Zea mays L.) landraces in the northern Guinea savanna and Sudan savanna in West and Central Africa appear to have some drought-adaptive traits. This study was initiated to assess the level of improvement in yield potential and other agronomic traits achieved under drought stress (DS) and i...

High cost of nitrogen fertilizer coupled with frequent occurrence of drought has forced many maize (Zea mays L.) growers in sub-Saharan Africa to either apply fertilizer below optimal dose or no fertilizer to their maize fields. The objectives of this study were to (i) compare the performance of ...

Nitrogen stress is a major nutrient constraint to maize productivity in the Northern Guinea savanna of West and Central Africa. Thus, improved maize germplasm tolerant to low N with the capacity to utilize N more efficiently together with improved agronomic practices appear to be the primary cont...

Low soil nitrogen limits maize (Zea mays L.) production in the West and Central African subregion. Levels of residual genetic variability were determined in two low‐N populations using selfed progeny evaluations, and results obtained indicate large genotypic and phenotypic variances for grain yie...
