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 ...

Yield stability analysis of nine spring bread wheat genotypes in the central highlands of Ethiopia
(African Crop Science Society, 1995)
Eight promising bread wheat lines and one standard check cultivars were evaluated for grain yield performance, stability and adaptation across nine environments of the central highlands of Ethiopia. Results of the combined ...

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 ...

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 ...

Estimating the economic impact of breeding nonspecific resistance to leaf rust in modern bread wheat
(American Phytopathological Society (APS), 1998)
Breeding for resistance to rust diseases in wheat is an example of productivity maintenance research. Productivity maintenance research is necessary to avoid contractions in the wheat supply curve that result from changes ...

On-farm evaluation of alternative bread wheat production technologies in northwestern Ethiopia
(African Crop Science Society, 1995)
Wheat ( Triticum spp.) is a major crop grown in northwestern Ethiopia. The primary wheat production constraints in this area include low soil fertility, use of unimproved and disease-susceptible varieties, and high weed ...
