Two greenhouse experiments were conducted to investigate the effect of phosphorus application and Rhizobium inoculation on the growth and nitrogen fixation of three tree legume species on a highland vertisol. The first experiment involved Sesbania sesban and S. goetzei, the second Leucaena panicu...

This paper reports on studies of Faidherbia albida trees and their effects on some properties of vertisols in the Ethiopian highlands. The study was carried at the experiment station of ILCA at Debre Zeit with 850 mm rainfall and at an altitude of 1850 m. Studies on the lateral and vertical influ...

In Ethiopia, Vertisols which are affected by water logging during the rainy season due to its physical and chemical characteristics are potential agricultural lands but are prone to soil erosion. The soil erosion rates of the cultivated Vertisols are accelerated due to the traditional practices o...

The productivity of the Vertisols in the Ethiopian highlands could be raised by facilitating the removal of excess water from the field in the main rainy season. This could be accomplished by the introduction of an animal powered broadbed maker (BBM) which shapes the soil into broadbeds and furro...

At the Debre Zeit Station Cereals (wheat and maize) and forage legumes (lablab, cowpea, vetch and clover) were grown as sole crops and as cereal/forage combinations on the broadbeds separated by drainage furrows (BBF). This is an improved land management system, developed by ILCA in collaboration...

Field experiments were conducted to study the effects of inoculation and application of P on the productivity of Desmodium intortum on an Ultisol and Sesbania sesban on a Vertisol, Alfisol and Ultisol in the Ethiopian highlands. On the Vetisol, the effect of drainage by using broad-bed-and-furrow...

Phosphorus deficiency is the major soil fertility problem limiting forage production in many parts of Africa. The objective of this study was to screen African Trifolium species for dry matter production, nutrient use efficiency and nitrogen fixation potential at different rates of applied Twenty...

New semiDwarf wheat (Triticum aestivum L.) cultivars and new land management practices for Vertisols are being introduced in Ethiopia. Our objectives were to (i) determine the variation of N and P contents and concentration in the grain and whether these are related to grain yield, (ii) test cult...
