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 ...
Article
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 ...
Article
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 ...
Article
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 ...
Article
Grain yield of wheat as affected by cropping sequence and fertilizer application in Southeastern Ethiopia
(African Crop Science Society, 1997)
Cropping systems in the Ethiopian highlands consist primarily of cereals in rotation with grain legume and oilseed crops; the proportional allocation among crop species varies with altitude, rainfall, and soil type. Barley ...
Article
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, ...
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
On-farm evaluation of an animal-drawn implement developed in Ethiopia for row placement of wheat seed and basal fertilizer
(African Crop Science Society, 1997)
Grass weeds are difficult to control by hand weeding in a broadcast wheat crop because several species are not easily distinguished from the crop at an early stage. Chemical weed control, on the other hand, can be highly ...
Article
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 ...
Article
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 ...
