Agro-ecological decision support systems for wheat improvement in Ethiopia: Climatic characterisation and clustering of wheat growing regions
(African Crop Science Society, 1999)
Wheat production environments in Ethiopia are highly heterogeneous with respect to natural resource characteristics, cropping systems, biotic and abiotic constraints. This paper analyses the agro-climatic resources of 20 ...

Performance of early maturing Katumani and Kito maize composites under drought at the seedling and flowering stages
(African Crop Science Society, 1998)
Two widely-used open pollinated maize (Zea mays L.) cultivars from East Africa, Katumani and Kito composites, developed and improved for early maturity, grain yield and drought escape were evaluated for drought tolerance ...

The effects of several crop management systems on bread wheat yields in the Ethiopian Highlands
(African Crop Science Society, 1997)
Crop management (CM) research conducted in Ethiopia has tended to quantify yield gains and losses associated with single management factors, making it difficult to determine the relative importance of main effects and ...

Grass weed competition with bread wheat in Ethiopia. 1. Effects on selected crop and weed vegetative parameters and yield components
(African Crop Science Society, 1996)
Competition effects of four of the predominant grass weed species in Ethiopia (Avena abyssinica Hoechst, Lolium temulentum L., Snowdenia polystachya Fresen (Pilg), and Phalaris paradoxa L.) on the morphological characters, ...

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 ...

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 ...
Article
Competitive ability of Ethiopian spring bread wheat cultivars with Avena fatua L.
(African Crop Science Society, 1995)
Competitive interactions of four spring bread wheat cultivars ( Triticum aestivum check for this species in other resources L.) with four wild oat ( Avena fatua check for this species in other resources L.) seedling densities ...
Article
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 ...
