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, ...

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 ...

Molecular characterization of diverse CIMMYT maize inbred lines from eastern and southern Africa using single nucleotide polymorphic markers 

Semagn, K.; Magorokosho, C.; Vivek, B.; Makumbi, D.; Beyene, Y.; Mugo, S.; Prasanna, B.M.; Warburton, M.L. (BioMed Central, 2012)
Background: Knowledge of germplasm diversity and relationships among elite breeding materials is fundamentally important in crop improvement. We genotyped 450 maize inbred lines developed and/or widely used by CIMMYT ...

Grain yield of barley 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 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 ...

Factors influencing adoption of stress-tolerant maize hybrid (WH 502) in western Kenya 

Salasya, B.; Mwangi, W.M.; Mwabu, D.; Diallo, A.O. (Academic Journals, 2007)
Non-adoption of suitable maize varieties was identified as the second most important constraint responsible for low maize yields in western Kenya. In order to increase adoption of suitable varieties it is important to know ...

Combining ability of maize inbred lines resistant to Chilo partellus (Swinhoe) in the mid-altitude environment of Kenya 

Gakunga, J.; Mugo, S.; Njoroge, K.; Olubayo, F. (Academic Journals, 2012)
Gene action conditioning important traits in maize is useful to breeders in order to design appropriate breeding methods. A study was conducted to determine the combining ability of 10 maize inbred lines adapted to Kenya?s ...

Diagnostic research to enable adoption of transgenic crop varieties by smallholder farmers in Sub-Saharan Africa 

Smale, M.; De Groote, H. (Academic Journals, 2003)
Diagnostic research is important in helping to create an enabling environment for promising biotechnology products in smallholder agriculture, before rather than after release. The biotechnology products that now hold ...

Grass weed competition with bread wheat in Ethiopia. 2: Prediction of grain yield loss and implications for economic weed control 

Taye Tessema; Tanner, D.G.; Mohammed Hasenna (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 ...
