Highlights the interactions between agronomy and economics in developing forage production techniques for the two main land-use situations in the subhumid zone of Nigeria, viz, cultivation and fallow. Presents break-even sorghum grain-stylo price ratios for different undersowing times, capital an...

Fodder production, dry season leaf retention, and concentrations of crude protein and in vitro dry matter (DM) digestibility in fodder of Desmanthus virgatus, Desmodium cinereum, Desmodium gyroides, and Cajanus cajan were compared under cutting on an acid soil in southern Ethiopia. Desmodium cine...

Poor cropland fertility and a rapidly rising demand for food force Sahelian farmers to cultivate more land and shorten fallow periods. This mostly leads to a gradual decline in crop yields per hectare, which can be counterbalanced by the systematic use of livestock manure on cropland. To assess t...

A study carried out to determine the chemical composition of Crotalaria ochroleuca ("marejea") at three stages of growth pre-anthesis, anthesis and post-anthesis. Feeding trials were conducted to study the effect of "marejea" supplementation of low quality Chloris gayana hay on the growth rate an...
