Sorghum (Sorghum bicolor (L.) Moench) is an important essential cereal crop in Ethiopia. Conversely, its productivity is low due to numerous biotic and abiotic factors. There are diverse and dynamic environmental conditions which needs detail and continue study on genotypes by environment interaction (GEI) to develop stable genotypes. The objective...

In Ethiopia, rice is one of the most important strategic food security crops and it becomes the source of income. In Southwestern part of Ethiopia, especially in Jimma zone, lack of high yielding, biotic and abiotic stress tolerant upland rice varieties were major problem for the reduction of yield. The objective of the present study was to estimat...

Twelve bread wheat varieties were evaluated across three environments during two main cropping seasons (2021 and 2022) at the highlands of Southwestern part of Ethiopia. The objectives of the study were to estimate the magnitude and nature of GEI for grain yield and to determine yield stability of wheat varieties in the highland areas of southweste...

Mono cropping is a common practice in agriculture, and usually causes serious economic losses due to soil degeneration, decreased crop yield and quality, and increased disease incidence, and pest occurance. It mainly due to changes in soil microbial communities, nutrient availability, and allelopathy effect. Recently, progressive studies have illus...

Ethiopia is a country which is known for its rich biodiversity and being a centre of origins for many crop species and diversities due to its wide range of altitudes, temperature extremes, huge amounts of rainfall, and different soil characteristics. Finger millet (Eleusine coracana L.) Gaertn) is an allotetraploid (2n = 4× = 36) annual cereal crop...

Sorghum (Sorghum bicolor [L.] Moench, Poaceaea family) (2n = 20) is the 5th most important cereal crop and is the dietary staple of more than 500 million people in 30 countries. In Ethiopia, sorghum is the third largest cereal crop in area coverage and total production preceded by tef and maize. In Ethiopia, South and Southwestern part of Ethiopia...

Objective: The objective of the study was to evaluate performance and identify high yielding and stable variety for southwestern part Ethiopia and recommend identified varieties for large scale production. Experimental Materials: Eight nationally released tef varieties were included in the study. The materials were obtained from Debre Zeit Agricult...

Article Info To evaluate performance and identify high yielding and stable varieties for the southwestern part of Ethiopia. Ten released finger millet varieties and one local check were tested at different locations of Jimma and Buno bedele zones. The experiment was laid out in a randomized complete block design with four replication. Each finger m...

Objective: The objective of the study was to identify high yielding and stable tef varieties across different locations of South and Southwestern part of Ethiopia. Methods: The experiment was conducted using 21 tef varieties obtained from a tef breeding program based at Debre Zeit Agricultural Research Center. The trial was laid out using a randomi...

Article Info The objectives of the study were to evaluate the yield performance of each genotype in relation to each environment, to examine the possible existence of different mega environments and to identify the winning genotype for each mega environment using GGE bi-plot method. Ten finger millet varieties which were for the experiment. The exp...

Triticale is a crop developed by crossing wheat (Triticum turgidum or aestivum) with rye (Secale cereal). It combines yield potential and grain quality of wheat with the disease and environmental tolerance including adaptability to difficult soils, drought tolerance, cold hardiness, disease resistance and low-input requirements of rye. Triticale gr...

Rice production in Ethiopia has started a few decades ago and now the country is proved to have reasonable potential to grow different rice types for rain fed lowland, upland and irrigated ecosystems. Rice is currently considered as a strategic food security crop and its use as a food crop, income source, employment opportunity and animal feed has...

Tef is the major Ethiopian cereal grown on 3.02 million hectares annually and serving as staple food grain for over 70 million people. However, the national average yield of tef is low 1.6 t ha-1. This is partially due to the use of unimproved local cultivars, and biotic and abiotic stresses. Therefore the experiment was designed to develop high yi...
