Development of wheat germplasm for stem rust resistance in Eastern Africa

Wheat (Triticum aestivum) rust outbreak is the primary production constraint in Eastern Africa. Ethiopia, Kenya and Uganda are hot spots for the epidemic of rusts, due to higher rates of evolution of new pathogen races, especially of the virulent stem rust (Puccinia graminis) race, Ug99. The objective of this study was to identify sources of resistance to the major pathotypes of stem rust prevalent in some countries of Eastern Africa.

Cold tolerant rice evaluation in Ethiopian highlands.

Ethiopia's geography is marked by mammoth depressions and mountains ranges due to the rift valley system that cuts across the country. Consequently vast arable lands are located at high altitudes more than 2000 meter above sea level. Rice was introduced to the country few decades ago nevertheless the production area is rapidly expanding. Rice can be grown in wide agroclimatic zones; however, low temperature stress is a series problem for rice growers at high elevations in the tropics.

Climate Change Adaptation Strategies of Maize Producers of the Central Rift Valley of Ethiopia

The impacts of climate change are considered to be strong in countries located in tropical Africa that depend on agri-culture for their food, income and livelihood. Therefore, a better understanding of the local dimensions of adaptationstrategies is essential to develop appropriate measures that will mitigate adverse consequences.

The extent of finger millet production in south omo zone in the case of south ari woreda.

In Ethiopia finger millet occupies 4% of the total area allocated to cereals (nearly half a million hectares) each year and also contributes about 4% to the total annual cereal grain production in the country. The production area increased from 342,120 ha to 368,999 ha with an increase of 7.3%, and the productivity increased from 3,769,290 to 5,241,911 quintals with a proportion of 28%. Six varieties (Tadesse, Padet, Wama, Baruda, Degu and Boneya) have been identified for cultivation to date.

Evaluation of pearl millet (Pennisetum glaucum L.) genotypes for yield and yield stability in South Omo and West Hararghe.

Sixteen pearl millet genotypes were evaluated in randomized complete block design with four replications during 2011 at four locations to study the magnitude of genotype by environment interaction for yield and yield related traits and identify the most stable high yielding genotypes.

Study on adaptability and stability of drought tolerant maize varieties in drought prone Areas of South Omo Zone, SNNPRS

Six improved drought tolerant maize varieties were tested at three drought prone woredas of South Zone. Randomized complete block design with three replications was used. Seeds were sown on a plot size of 4.5 m x 6 m (27 m2) in rows of six per plot at a spacing of 75 cm between rows and 25 cm between plants. Drought tolerant varieties of two types namely hybrids (MH-130 & MHQ-138) and open pollinated varieties (Melkassa-4, Melkass-6Q, Melkass-7 and Melkass-2) was used. ANOVA revealed significant differences (p

Effect of cultivation frequency on growth, yield andyield components of bread wheat (Triticum Aestivum(L.) at Selmamer, Southern Ethiopia

A field experiment was carried out at Selmamer during the 2014 cropping season to determine the effects of cultivation frequency on growth, yield and yield components of bread wheat (Triticum aestivum L.). The treatments used in the study were seven cultivation frequencies (30 DAE, 45 DAE, 60 DAE, 30 and 45 DAE, 30 and 60 DAE, 45 and 60 DAE, 30, 45 and 60 DAE) and one control or no cultivation. The experimental design was a randomized complete block design (RCBD) with four replications.

Evaluation of different moisture conservation practices on growth, yield and yield components of sorghum at Alduba, southern Ethiopia

A field experiment was conducted on research field of Alduba, Bena Tsemay district of south Omo zone, southern Ethiopia to determine the effects of different moisture conservation practices on growth, yield and yield components of sorghum [Sorghum bicolor (L.) Moench] under rain fed condition in 2010. The experiment was undertaken with four improved moisture conservation practices and one farmers’ practice (farmers’ practice, circular pitting, half moon, tied ridge, and open ridge). The experimental design was a randomized complete block design /RCBD/ with four replications.

Evaluation of sorghum (Sorghum bicolor (L.) Moench) varieties, for yield and yield components at Kako, Southern Ethiopia

A field experiment involving seven improved sorghum [Sorghum bicolor (L.) Moench] varieties and one local check was carried out at Kako farmers’ training center during the 2006 main cropping season to identify the best performing variety to the lowlands of South Omo Zone. The sorghum varieties included in the field experiment were seven improved (Seredo, Meko-1, 76TI#23, Gambella 1107, Teshale, Gubiye, Abshir) and a local check. The experimental design was a randomized complete block design (RCBD) with three replications.

Determination of optimum seed rate for productivity of rice (Oryza Sativa L.), at Woito, Southern Ethiopia

A field experiment was undertaken at Woito, to determine the effect of seed rate on productivity of rice (Oryza Sativa L.), at Woito. The experiment was conducted with five levels of seed rate (40, 60, 80, 100 and 120 kg ha-1). The treatments were laid out in a randomized complete block design (RCBD) with four replications. Phenological and growth parameters such as yield and yield components, total biomass and harvest index were studied. The result showed that all the phenological and growth parameters except panicle length per plant were significantly affected by the treatments.
