Presents results of a study conducted at Debre Zeit, Ethiopia, to examine the differences in mineral composition, root N contents and their rates of transformation in the soil of different species of four genera of forage legumes, viz, Trifolium, Lablab, Medicago and Vicia. Also examines the effe...

Alfalfa or lucerne (Medicago sativa L.) is an important forage legume grown extensively in the world. There have been relatively few investigations on the adaptation of alfalfa to soils found in suitable eco-zones in Africa. In the present investigations, twenty accessions were evaluated for tole...

Sesbania have multifarious utilization, and in many instances growth rate is one of the most important criteria for the selection of suitable Sesbania. This paper reports results of a study on the growth rates of Sesbania on two acid soils both low in available P, but one with toxic levels of Al....

Although lablab (Lablab purpureus L.) is grown in many parts of Africa relatively little investigation has been done on its adaptation to acid soils, which are generally low in available In the present study, lablab was evaluated for tolerance to acidity and low available P on two Ethiopian soils...

This document starts by describing the five main agroecological zones of sub-Saharan Africa, viz, arid, semi-arid, subhumid, humid, and highland, and summarising population and agricultural production. Then it goes to the main topics that includes inter cropping systems; criteria for evaluating t...

An alfalfa field experiment was conducted at the Debre Zeit Experiment station for a period of 2 years with the main objective of investigating the effects of cattle manure om dry matter yields, plant tissue nutrient concentration and plant nutrient uptake. Dry matter yields were significantly in...

Most soils in sub-Saharan Africa are P deficient, but the high cost of water-soluble P fertilizers limits the use of P fertilizers by resource-poor farmers. A low-cost alternative is to apply phosphate rocks. We evaluated the effectiveness of unacidulated (PR), 25 percent partially acidulated (PA...
