Potential for cereal-based double cropping in Bale Region of Southeastern Ethiopia
(African Crop Science Society, 1994)
A double cropping trial was conducted under bimodal rainfall conditions for two years at the Sinana Research Centre in southeastern Ethiopia. Compared to the traditional farmers’ practice of fallowing land during one of ...
Article
Grain yield of barley as affected by cropping sequence and fertilizer application in Southeastern Ethiopia
(African Crop Science Society, 1997)
Cropping systems in the Ethiopian highlands involve rotations of cereals with grain legume and oilseed crops; the proportional allocation among crop species varies with altitude, rainfall, and soil type. Barley (Hordeum ...

The economics of small-scale wheat production technologies for Kenya
(CIMMYT, 1989)
Kenya is a net importer of wheat and is projected to remain so to the end of this century. Wheat is grown in Kenya using mechanized production methods that differ little from what might be observed in many industrialized ...

Races of Puccinia graminis f. sp. tritici with combined virulence to Sr13 and Sr9e in a field stem rust screening nursery in Ethiopia
(American Phytopathological Society (APS), 2012)
North American durum lines, selected for resistance to TTKSK (Ug99) and related races of Puccinia graminis f. sp. tritici in Kenya, became susceptible in Debre Zeit, Ethiopia, suggesting the presence of stem rust races ...

First report of Puccinia graminis f. sp. tritici races with virulence to wheat stem rust resistance genes Sr31 and Sr24 in Eritrea
(American Phytopathological Society (APS), 2011)
Wheat stem rust, caused by Puccinia graminis f. sp. tritici, has historically been a major limiting factor in wheat production. Identification of isolate Ug99 in Uganda in 1999 highlighted the vulnerability of a large ...
Article
The spread of stem rust caused by Puccinia graminis f. sp. tritici, with Virulence on Sr31 in wheat in Eastern Africa
(American Phytopathological Society (APS), 2006)
Stem rust resistance in wheat cultivars with Sr31 has been effective and durable worldwide for more than 30 years. Isolates of Puccinia graminis f. sp. tritici with virulence to Sr31 were detected in Uganda in 1999 (1). ...

Grass weed competition with bread wheat in Ethiopia. 2: Prediction of grain yield loss and implications for economic weed control
(African Crop Science Society, 1996)
Two multi-year studies were conducted in Ethiopia to examine the effects of competition by the predominant grass weed species on bread wheat (Triticum aestivum L.). In the first experiment, the effects of four grass weed ...

International wheat breeding research in Eastern and Southern Africa, 1966-97
(CIMMYT, 2000)
This paper describes and analyzes some of the impacts of wheat improvement research in seven countries in the Eastern and Southern regions of Africa. the countries South Africa, Ethiopia, Sudan, Kenya, Zimbabwe, Tanzania, ...
Article
Improvement of durum wheat yield and associated effects on morpho-physiological characters
(African Crop Science Society, 1995)
Six durum wheat ( Triticum turgidum var. durum check for this species in other resources ) cultivars released in the central highlands of Ethiopia from 1967 to 1992, were evaluated to estimate progress in improving grain ...
Article
Improvement in yield of bread wheat cultivars released in Ethiopia from 1949 to 1987
(African Crop Science Society, 1995)
Thirteen bread wheat ( Triticum aestivum check for this species in other resources L.) cultivars popular in the highlands of Ethiopia and representative of the period from 1949 to 1987 were studied for two cropping seasons ...
