The role of residue characteristics in enhancing the availability of P was investigated in a greenhouse study using two soils from the northern Guinea savanna (NGS) and four from the derived savanna (DS) zones of the West African moist savanna. Eight organic residues of varying C-to-P ratio were ...

The banana weevil, Cosmopolites sordidus (Germar), is a nocturnal insect that is not readily observed in banana fields. Knowledge on its distribution is essential for the design of management strategies that target the adult stage. Marked weevils were released into seven-year-old banana plots. Te...

Removal and destruction of banana crop residues after harvest has been widely recommended for the control of banana weevil, cosmopolites sordidus control. However, there is scanty information of the actual effect of this practice on the banana weevil populations and damage. This study aimed at in...

The paper investigates the variation in laboratory fodder quality traits in stover of 16 cultivars of pearl millet grown over 2 consecutive years and subjected to two different fertilizer regimes and planting densities. Stover quality traits were nitrogen and sugar content, in vitro digestibility...

Investigates Nitrogen and Phosphorus transfers in a crop - livestock system in the subhumid zone of Nigeria. Estimates N and P removed from cropland during crop residue grazing and returned to the land through manure, and the contribution crop residues make to cattle diet during the dry season.

Discusses the contribution of crop residues to livestock feed resources during the dry season in the Abet plains, central Nigeria. Determines the grain and vegetative dry matter yields of predominant crops and the relationship between the two; percentage composition of crop residues; fiber, silic...
