Drought is one of the major abiotic constraints seriously influencing bread wheat (Triticum aestivum L.) genotype production in Ethiopia. Genetic resources and selection methodologies are among the prerequisites to improve the efficiency of breeding for drought tolerance. The objectives of this study were to determine the principal selection indices for...

Sweet potato activitiy at Dera district

The Somali region of Ethiopia is a typical pastoral area, that occupy >50% of the 0.7 million km2 rangeland in the country. However, all forms of rangeland degradations have become major threats to enhance a sustainable pastoral-livestock production in Ethiopia. But except for very few studies on rangeland condition assessments, no or too little...

Tef [Eragrostis tef (Zucc.) Trotter] is extensively cultivated cereal crop in Ethiopia where it is annually grown by about 6.5 million smallholder farmers on about 30% of the total area allocated to cereal crops.However, the productivity of tef is very low compared to other cereals mainly due to lack of high yielding and lodging tolerant cultivars. The...

Agriculture needs to be more efficient and productive to provide more food and feed with less environmental damage to which agricultural research has a lot to offer by designing a broader research agenda. This calls for overhauling the research system towards creating a seamless coordination mechanism, assigning adequate work force, and improving physical...

Study on the effect of phosphorus fertilization and seed dressing fungicide on occurrence of pea aphid, Acyrthosiphon pisum and yield of lentil was conducted at Debre Zeit and Chefe Donsa for six consecutive years. Lentil genotypes Alemaya and ILL-7664 were sown at the rate of 60kg/ha on 2m wide and 4m long plots. Treatments consisted Apron star 42WS (@...

The ever increasing population pressure with subsequent dwindling grazing land area pushes greater dependence of livestock on crop byproducts as feed source. There is a hypothesis that maize producers in the mixed farming system value the feed attribute of maize varieties for adoption. This study was conducted to investigate farmers’ rankings of maize...

This study assesses the commercial behavior of smallholder farmers in the moisture-stress haricot bean based farming systems of central Ethiopia along with the determinants of smallholder farmers’ engagement in the sales of most important crops. Descriptive and Tobit regression analyses are used to determine the key factors that influence household...

Silica based inert dusts are eco-friendly alternatives to control stored grain insect pests due to environmental and health concerns associated with use of synthetic insecticides. A study was conducted to determine the efficacy of filter cake (a silica-based inert dust) on the granary weevil, Sitophilus granarius (L.) and lesser grain borer, Rhyzopertha...

Judicious use of pesticides in agriculture provides many important benefits and thus, they are used in the agricultural sector of Ethiopia. Trends in pesticide use between 2004/05 and 2019/20 ‘Meher’ crop seasons by smallholder farmers on field and horticultural crops at national and regional levels were assessed. For each cropping season and each crop...

To evaluate the integrated effect of Sulfur and biological strains on nodulation and yield of soybean at Jimma zone in 2019 cropping season

The objectives of the study were to characterize the production system of camel in Yabello and Melka Soda districts and to characterize phenotypically camel based on quantitative and qualitative traits. A total of 192 households were selected for characterization of the production system and 300 camels were sampled randomly for characterization of...

Weeds are one of the major constraints limiting haricot bean productivity and production. Field experiments were conducted on the effect of weed managements on weeds and grain yield of haricot bean (Phaseolus Vulgaris L.) at Melkassa Agricultural Research Center from 2011 - 2013. The objective was to determine the effect of weed managements, varieties and...

Boswell papyrifera is a tree species which is found in Amhara, Tigray, and Benshangul Gumuze region and used for the production of frankincense. Frequent tapping at different rounds and at different position of the tree is made to produce frankincense. A study aiming at evaluating the health status of tapped Boswellia papyrifera was carried out on samples...

Linseed (Linum usitatissimum L.) is important to the Ethiopian farmers in terms of its various home uses generating potential in both domestic and foreign markets. One of the major linseed production constraints in the country is the lack of high yielding and high oil content varieties. This experiment was conducted at Hossaina, Kokate, Dida-Midore and...

Thermal food processing is known to inactivate harmful microorganisms in foods. However differ-ent microbes have varying degrees of heat resistance. During this study, thermal inactivation characteristics of aflatoxigenic Aspergillus flavus and A. parasiticus conidia isolated and charac-terized from Ethiopian hot red pepper powder were determined by the...

A Scientometric analysis of the Ethiopian Journal of Agricultural Sciences from volume 1 to 24 covering 279 papers is reported. The journal was covering all areas of agriculture with most papers having single, two or three authors and; in a rare cases up to nine and twelve authors. The number of papers in agronomy, field crop breeding and crop protection...

to determine phosphorus requirements for Field pea

In drought prone areas of Ethiopia, maize is produced by small-scale farmers’ where additional inputs are rarely applied. Although genetic tolerance is recommended for moisture stress, there is limited information on drought-tolerant genotypes reaction to variable environments. In this study, eight drought tolerant lines and their diallel crosses were...

Using a production function, marginal productivity of farm inputs and benefit-cost analysis, we explore the economics of selected water control technologies. From the production function, all farm inputs, including irrigation water is found to have a significant and positive effect on yield. Marginal value products of farm inputs are found to be positive...
