The effects of several crop management systems on bread wheat yields in the Ethiopian Highlands 

Amsal Tesfaye Tarekegne; Tanner, D.G.; Amanuel Gorfu; Tilahun Geleto; Zewdu Yilma (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 

Taye Tessema; Tanner, D.G.; Mengistu Hulluka (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 

Tanner, D.G.; Zewdu Yilma; Lemma Zewdie; Girmay Gebru (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 ...

Improvement of durum wheat yield and associated effects on morpho-physiological characters 

Amsal Tesfaye Tarekegne; Tanner, D.G.; Tesfaye Tesemma; Getinet Gebeyehu (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 ...

Improvement in yield of bread wheat cultivars released in Ethiopia from 1949 to 1987 

Amsal Tesfaye Tarekegne; Tanner, D.G.; Getinet Gebeyehu (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 ...
Article
Thumbnail

Grain yield of wheat as affected by cropping sequence and fertilizer application in Southeastern Ethiopia 

Asefa Taa; Tanner, D.G.; Kefyalew Girma; Amanuel Gorfu (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 ...

On-farm evaluation of an animal-drawn implement developed in Ethiopia for row placement of wheat seed and basal fertilizer 

Asefa Taa; Tanner, D.G.; Melesse Temesgen; Kefyalew Girma (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
Thumbnail

Grass weed competition and calculated economic threshold densities in bread wheat in Ethiopia 

Taye Tessema; Tanner, D.G. (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
Thumbnail

Response of bread wheat to rate and timing of nitrogen application in marginal rainfall zone in Ethiopia 

Zewdu Yilma; Tanner, D.G. (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 

Selamyihun Kidanu; Tanner, D.G.; Tekalign Mamo (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, ...
