Maize data

Iron (Fe) deficiency is the major constraint for soybean cultivation in calcareous soils. Its availability affects symbiotic association of the host plant and the endosymbiont and eventually the yield of soybean. However, the effectiveness of integrated application of Bradyrhizobium and Fe fertilizer on nodulation and yield of soybean genotypes with...

The irrigation based cotton production system in the Middle Awash basin has got progressive productivity decline in the present times. A study was made to provide basic information with regard to the present fertility status and physical characteristics on the soils of the basin. Based on soil color, texture, and land use, 12 pedons were opened in...

Irrigated agriculture is a major human activity, which often leads to secondary salinization of land and water resources in arid and semi-arid conditions. Soil salinity is an enormous problem for agriculture under irrigation as it affects the growth and development of plants in Ethiopia; the problem is widespread in the rift valley areas where middle...

Integrated use of organic and inorganic fertilizer rates on barley production in Liben Jawi

Currently, poultry producers in developing countries are facing problems of high cost and poor quality of poultry feed. Insects are one of the potential protein sources for poultry feed. The use of insects as poultry feed is not in direct competition with human for food consumption. The objective of this paper is to review the current work related to the...

Southwestern part of Ethiopia is believed to be the origin of Arabica coffee which possesses the country to have the largest diversity in coffee genetic resources. Coffee quality determines the relative price as well as the usefulness of a given quantity of coffee. Therefore, the experiment was conducted to evaluate coffee quality of BenchMaji and Sheka...

A field experiment was conducted on Nitisols of Asossa Agricultural Research Centre during 2017/18 to 2018/2019 cropping season toinvestigate the response of yieldpartial budget analysis to biofertilizer rates.The N fertilizer treatments considered in the study consisted of six levels (rates) of biofertilizer, one nationally recommended inorganic N and...

Significant fodder production cannot easily be realized mainly due to the pressure on land for the production of staple food crops to feed the ever increasing human population in Ethiopia. To meet the parallel increasing demand for green fodder, one of the alternatives is hydroponic fodder to supplement the meager pasture resources. A study was conducted...

An experiment was conducted to investigate the effects of different spacing of elephant grass (Pennisetum purpureum) and vetch (Vicia dasycarpa and Vicia villossa) intercropping on plant height, leaf to stem ratio, tillering, stand count, and subsequent dry matter yield (DMY) of elephant grass. The forages for field experiment were evaluated during the...

Although soil and agronomy data collection in Ethiopia has begun over 60 years ago, the data are hardly accessible as they are scattered across different organizations, mostly held in the hands of individuals (Ashenafi et al.,2020; Tamene et al.,2022), which makes them vulnerable to permanent loss. Cognizant of the problem, the Coalition of the Willing...

Ethiopia was using urea and DAP fertilizers as sources of nitrogen and phosphorous nutrients for a long time. However, the crop and agro-ecology diversity in the country demand more multi-nutrient blends including micronutrients than nitrogen and phosphorus. This increasing demand requires evaluation of different fertilizer resources based on soil type,...

Liming acid soils is one of the available intervention options to amend soil acidity and increase crop production and productivity. Nevertheless, selection of lime requirement determination method suitable to the soil conditions in a particular area is a pressing issue. Therefore, this research was carried out to evaluate lime requirement determination...

New fertilizer testing field evaluation

Tef (Eragrostis tef) is extensively cultivated by over 6.5 million smallholder farmers in Ethiopia. However, the productivity of the crop remains low mainly due to the limited use of improved technologies including seeds. In this study, three recently released and one old (as a check) tef varieties were evaluated on 254 lead farmers’ fields with the main...

This activity was implemented to identify the most important plant nutrients in 2020 cropping season

This study employed the Cobb-Douglas stochastic frontier production function to measure the level and determinants of technical efficiency of smallholder rice producers in the Fogera district of Amhara Region, Ethiopia. A multistage sampling procedure was used to select 202 rice producers sample farmers in 2016. The result of the analysis showed that the...

Highland part

A field experiment was conducted at Vertisol of Ginchi, Dandi district, West Shewa, Ethiopia during 2015/16 and 2016/17 cropping seasons to study the effect of different indigenous rhizobial isolates on the yield and yield components of chickpea. Eight rhizobial isolates (CP-5, CP-7, CP-9, CP-10, CP-11, CP-17, CP-100 and EAL-004), one positive control (18...
