Impact of storage on sugar loss in sorghum stalks

Sweet sorghum sugars are feedstock for bio-products. Extending production beyond harvest will maximize profitability, but is limited by loss of fermentable sugars during storage. Cutting stalks into billets increases surface area for processing, but can increase sugar degradation. The effect of storing whole sorghum stalks was investigated. Whole stalks of cultivar M 81-E had the highest losses at 44.2% of fermentable...

The functional characterisation of soybean (Glycine max L.) rhizospheric bacteria indigenous to Ethiopian soils

Ethiopia remains a net importer of soybean partly due to low average yields which may be improved by inoculation with rhizobia and/or plant growth promoting rhizobacteria (PGPR). The functional characterisation of 231 rhizobacteria isolated from the rhizosphere of soybean grown in 102 soils collected from different pedo-climatic regions of Ethiopia was carried out. Isolates were initially characterised by Gram staining...

Influence of plant population density on growth and yield of Rosemary (Rosmarinus officinalis L.) at Wondo Genet South Ethiopia

A field experiment was conducted at Wondo Genet Agricultural Research Center in the production season of 2013/2014 and 2014/2015 with the objective of identifying the best combination of intra and inter-row spacing for optimum plant population density of rosemary. The treatments consisted of five intra-row spacing (50, 60, 70, 80, and 90 cm) and three inter-row spacing (60, 80 and 100 cm) with a total treatment...

Effect of flowering slips on the yield of sweet potato (Ipomoea batata (L.) Lam.) tubers

Creating a nursery for sweet potato cultivation in tropical and subtropical areas including Okinawa is not necessary because planting is possible throughout the year. In general, sweet potato blooms under natural conditions in tropical and subtropical areas. Sweet potatoes are grown from non-flowering slips, which farmers generally select from a field of a previous cropping. Although the selection and collection of...

Agromorphological evaluation within a collection of local tomato (Solanum lycopersicum L.) populations collected in Burkina Faso and Mali

Tomato is a vegetable of great economic importance in Burkina Faso. This study evaluated agromorphological diversity within 40 tomato accessions from Burkina Faso and Mali. Trials were conducted during 2015 growing season and IPGRI descriptors were considered in collecting data on field as well as in laboratory. Results revealed the collection to be interestingly diversified. All studied characters presented several...

Effects of blended fertilizer types and rates on fruit yield and nutrient use efficiencies of hot pepper (Capsicum annuum L.) at Asossa, Western Ethiopia

A field experiment was conducted to evaluate the effects of different blended fertilizer types (NPSB and NPSBZn) and their rates on fruit yield, nutrient concentration, nutrient uptake and nutrient use efficiency of hot pepper at Assosa, Western Ethiopia. The experiment was set with eight treatments (recommended NP, three different blended rates for each NPSB and NPSBZn and unfertilized plot) laid out in randomized...

Some maize agronomic practices in Ethiopia: A review of research experiences and lessons from agronomic panel survey in Oromia and Amhara regions

There is a huge maize yield gap in Ethiopia. The use of improper maize agronomic practices could contribute to maize yield gaps. Agronomic panel survey (APS) and a baseline survey were carried out by EIAR and CSA, respectively in collaboration with CIMMYT for three years (2015-17) to assess the rates and types of inorganic fertilizers applied; maize varieties used and plant densities maintained by farmers in major maize...

Growth performance and carcass characteristics of cross-bred rabbits fed diets containing palm kernel oil residue

This study was conducted to explore the potential of palm kernel oil residue (PKOR), as substitute for wheat bran (WB) on growth performance and carcass characteristics of cross-bred rabbits in Ghana. Forty-eight seven-week old rabbits (1113± 318.20 g) were randomly allotted to 4 dietary treatments in a completely randomized design. The rabbits were given diets in which WB was replaced with PKOR at 0, 25, 50 and...

Yield gaps, adoption and seed commercial behaviour: Implications for chickpea seed system in Ethiopia

The paper presents the yield gaps, adoption of improved varieties and the commercial behaviour in seed of smallholder chickpea producers based on the primary data collected from 612 randomly selected farmers covering 36 kebeles from 18 chickpea-producing districts, in 2017. The results indicate that the estimated average yield gaps were lower by 37.97 and 49.17% for desi chickpea and by 29.62 and 40.97% for kabuli...

Effect of level and time of nitrogen fertilizer application on growth, yield and yield components of maize (Zea mays L.) at Arba Minch, Southern Ethiopia

Maize is most important cereal crop used for human diet, livestock fed, and for many industrial applications in many parts of the world. However, the national average productivity is quite below the world average which might be attributed to nutrient deficiency among many problems. A field experiment was conducted during 2016/2017 croppping season to determine the effect of level and time of nitrogen fertilizer...

Influence of Nitrogen and Phosphorus fertilizer Rates on Seed Yield, Yield Components and Quality of Onion (Allium cepa L.) at Kulumsa in Arsi Zone, South East Ethiopia

Onion is an important vegetable crop commercially grown both by large and small scale farmers in Ethiopia. Its production is highly dependent on availability of high and good quality seed, which is constrained by a number of problems including declining soil fertility and inappropriate fertilizer application. A study was conducted to investigate the effects of nitrogen (N) and phosphorus (P) fertilizer rates on onion...

Effect of planting time and fungicide application frequency on severity of late blight (Phytophthora infestans), yield and yield components of potato (Solanum tuberosum L.) at Kulumsa, Southeast Ethiopia

Phytophthora infestans is the major bottleneck in potato production in Ethiopia. Selection of appropriate planting time is highly location specific and the most important subject in rain-fed potato production. However, research recommendation on optimum planting time and fungicide application frequency for high lands area of Arsi (Kulumsa) is lacking. Thus, field experiment was carried out to evaluate the effect of...
