Low soil fertility, particularly nitrogen(N)and Phosphorus(P) are among the most yield-limiting nutrients in Ethiopia. Due to blanket NP application at the national level, the response of hybrid maize in Ethiopia is inconsistent and not satisfactory. Hence, a field experiment was initiated to investigate the response of hybrid maize (Zea mays L.) to the...

This study is assessing the performance of the agricultural extension system and identifying factors explaining it. The paper used both quantitative and qualitative data collection methods. Quantitative data gathered based on a questionnaire survey of 143 development agents (DAs) in Minjar Shenkora and Ada’a districts. Qualitative data were collected from...

The objective of this study was to look into the possibility of using the different lignocellulosic biomasses for Pleurotus sajor-caju (oyster mushroom) cultivation. The mushroom species was cultivated on nine types of substrates; namely three acacia species, three types of straws, coffee husk and saw dust obtained from two types of timber species. Thirty...

This study was conducted to evaluate the productive performances of crossbred dairy cattle at Holetta agricultural research center’s dairy farm. A total of 6685 performance records were used and analyzed to determine the effect of period of calving, season of calving, parity and genetic group. Parameters used as indicator of productive performances were...

ABSTRACT Sheath rot of rice, Sarocladium oryzae [(Sawada) W. Gams & D. Hawksw], is currently regarded as one of the most serious rice diseases in Fogera plains. Varietal resistance is the most cost-effective and eco-friendly management strategy for the small-scale farmers. An investigation was conducted to identify resistant sources among rice...

This study was conducted for two consecutive years to find optimum onion spacing under full irrigation, which allows the maximum yield of onion at Kencho kebele of Uba debretsehay woreda Gofa Zone Southern, Ethiopia through the support of the Participatory Small-scale Irrigation Development Program(PASID II). The experiment has four levels of onion...

Combining ability estimates are important genetic attributes ina maize breeding program aiming to develop stable andhigh yielding hybrids and synthetic varieties. The objectives of this study were to estimate combining ability effects of locally developed and introduced early generation maize inbred lines for grain yield, yield related traits, and...

Bacillus firmus, commercial WP formulation (BioNem) was evaluated against root-knot nematode, Meloidogne incognita on tomato plants under field conditions of Dire Dawa and Haramaya University (Ethiopia). Studies were conducted with the objectives to find out the effect of BioNem on nematode infestation and plant growth/yield of tomato and to compare two...

The continuous increase of input costs and volatility of output prices have made the profitability and sustainability of smallholder cotton production in question. This study was carried out to examine the profitability of irrigated cotton production at Amibara district in the Middle Awash Valley under smallholder producers. 30 producers were purposively...

An experiment was carried out to assess the diversity of castor germplasm in Ethiopia. A total of 102 accessions, one elite genotype and two standard varieties were characterized at Melkassa and Arsi Negelle, in the Central Rift Valley of Ethiopia using 12 traits for one during 2013 main season. Analysis of variance, principal component and cluster...

This study aimed at analyzing commodity level determinants of output side market participation of haricot bean based on cross sectional primary data collected from 123 randomly selected haricot bean producers sample households in six kebeles in Misrak Badawacho District, Hadiya Zone, Southern Nations Nationalities and Peoples Regional State, Ethiopia. The...

A study was conducted to evaluate the effect of fenugreek (Trigonella foenum-graecum L.) seed powder on growth performance, carcass characteristics and meat quality of broilers. A total of 156 day-old unsexed broiler chicks (Cobb 500) were randomly assigned to four treatment groups in a completely randomized design with three replicates of 13 chicks each...

A study was carried out at the Tissue Culture Laboratory of Melkassa Agricultural Research Centre, Ethiopian Institute of Agricultural Research (EIAR) to investigate the effects of different types and concentrations of cytokinin's and auxins on shoot initiation and multiplication, and in vitro shoot rooting of three banana varieties using shoot-tip...

Common bean is one of the major pulse crops which played an important role to the Ethiopian national economy and to farmers as food and cash income. Ethiopia ranked third in common bean production in Eastern and Southern Africa. The country exported 40 percent of its total common bean production in 2010. Despite the wide dissemination of improved common...

The article presents the historical evolution of attempts made in Ethiopia to strengthen the agriculture research and extension linkages since the start of formal agricultural research and extension in the early 1950s. The result reveals that there is a gradual improvement with increased types and mechanisms of the research-extension linkage in recent...

Composite soil samples were collected from the Nura Era Citrus Farm. The analysis followed standard laboratory procedures to determine the physical properties, nutrients, and other chemical properties. Then, composite leaf samples from non-bearing branches were collected from the same farm and analyzed for the dry matter-based total concentration of...

An experiment was conducted at Holetta and Debre Zeit Agricultural Research Centers dairy herd in 2011 to evaluate the number of embryos collected per super-ovulated donor cow, estrus rate (ER) and pregnancy rate (PR) of recipient cows/heifers after embryo transfer. For super-ovulation treatment a total of 19 Holstein Friesian (HF) x Boran crossbred cows...

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...

Severe soil degradation and fertility depletion have resulted in poor soil health and low crop productivity in the cultivated land of most Ethiopian highlands. Thus, a three-year experiment from 2013 to 2015 was conducted to assess the potential of crop rotation and organic matter application for recovery of the soil health and crop productivity of...
