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, ...

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 ...

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 ...

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 ...

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

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