Response of bread wheat to rate and timing of nitrogen application in marginal rainfall zone in Ethiopia
(African Crop Science Society, 1994)
Nitrogen fertilizer rate by timing trials were conducted on bread wheat (Triticum aeslivum L) in peasant farmers' fields during two annual cropping seasons for three years in a drought-prone district of southeastern Ethiopia. ...
Effect of nitrogen fertiliser applied to tef on the yield and N response of succeeding tef and durum wheat on a highland vertisol
(African Crop Science Society, 1999)
A trial was conducted on an Ethiopian Vertisol from 1990 to 1995 to determine the residual effect of fertiliser N applied to tef (Eragrostis tef) following chickpea (Cicer arietinum) on the grain and straw yield, N content, ...
Grass weed competition and calculated economic threshold densities in bread wheat in Ethiopia
(African Crop Science Society, 1997)
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 grain yield, yield ...
Farmers' wheat seed sources and seed management in the Enebssie area, Ethiopia
(IARC; CIMMYT, 1998)
This study in Enebssie area, Ethiopia, aimed to identify farmers' wheat seed acquisition and transfer mechanisms; explore problems related to those mechanisms; document the status of previously released wheat varieties; ...
Adoption of improved wheat technologies by small-scale farmers in Mbeya District, Southern Highlands, Tanzania
(United Republic of Tanzania; CIMMYT, 2001)
This study was conducted to gain an understanding of how small-scale farmers in Mbeya District have adopted improved wheat technologies promoted by the wheat research program at MARTI-Uyole. The specific objectives were ...
International wheat breeding research in Eastern and Southern Africa, 1966-97
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, ...
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 ...
Estimation of optimum plot dimensions and replication number for wheat experimentation in Ethiopia
(African Crop Science Society, 2000)
Bread wheat was row and broadcast sown using uniform crop management practices on a research station soil classified as a haplic Nitisol, situated in a major wheat producing region of Ethiopia, during the 1996 and 1997 ...
Glutenin composition, quality characteristics, and agronomic attributes of durum wheat cultivars released in Ethiopia
(African Crop Science Society, 2002)
Eleven cultivars of durum wheat (Triticum durum L. var. durum Desf.) were evaluated across five environments in Ethiopia for grain yield, 1000 kernel weight, protein concentration, gluten strength, mixing time, mixing ...
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 ...
