Two methods of DNA extraction and purification in eggplant molecular research were investigated. FTA PlantSaver card and DNAzol were optimized, simplified and presented. The aim was to discard the rigorous protocols and help save energy, resources and time wasted in DNA extraction during molecular research in eggplant. DNA was extracted from fresh leaf of 18-day-old eggplant seedlings. Quality of genomic DNA extracts was verified on 1% agarose gel electrophoresis and viewed on a UV-transillumina...

The study was conducted
on investigating effects of Eucalyptus camaldulensis on the performance of adjacent crop productivity for the benefits over adverse effects
of it versus different land uses in district Mecha of Western Amhara region, Ethiopia.
This research was carried out with the aim to test
the performance of neighbouring crops grown near E. camaldulensis on the
effects on plant growth performance and grain yield. Eucalypts has many important
uses and a reliable source of...

Field experiment
was conducted in 2014 to test the efficacy of different organic amendments on
the control of root-knot nematode (Meloidogyne spp.). The different materials are sole neem, sole poultry manure, and a combination
of neem and poultry manure. Neem was applied at the rate of 160 g per plot,
poultry manure was applied at the rate of 1120 g per plot, combination of neem
and poultry manure was applied at 1280 g per plot and Furadan was applied at 1 ...

The aim of this paper is
to review the potential effect of climate change on dynamics of coffee berry borer and to generate information for
researches concerned on it. Coffee ( Coffea arabica L.), which is
originated in Ethiopia, is the backbone of the country’s economy. It accounts
for 70% of the foreign exchange earning, 10% of the government revenue and
employs 25% of the domestic labor force. There are four coffee production
systems in Ethiopia such as modern plantation, gardens, semi-...

Ethno botanical study on traditional medicinal plants were conducted
between November, 2013 and September, 2014 in Bensa Woreda, Southern Ethiopia
and documented different types of traditional medicinal plants used by the
indigenous peoples. The study was focused on identifying medicinal plants,
plant habit, disease treated, plant parts used, way of knowledge acquired,
methods of preparation, route of administration, importance/indication, and
ingredients added. ...

A field experiment was conducted for two consecutive years (2013 and
2014) during the dry periods under irrigation at Dabat District, Northwestern
Ethiopia to select the best adaptable and high yielder varieties. Five garlic
varieties (BishoftuNech, Kuriftu, Tseday 92, MM-98 and the local) were planted
on randomized complete block design with three replications. Data on days to
emer- gence, days to maturity, pseudo stem height, number of leaves per plant,
bulb diameter, number of cloves per bulb...

Flea beetles are the most destructive insect pests of cotton in
Northwestern part of Ethiopia. Damage is the most severe when seedlings are
attacked and may necessitate extensive resowing. A field experiment was
carried out in Metema districtfrom June to December in 2007 cropping season to
estimate yield losses due to cotton flea beetle and to determine the efficacy
of seed dressing and foliar insecticides against Podagrica puncticollis. The treatments were arranged by using RCBD
with thr...

Aflatoxin is the most potent toxic substances, these are the group of closely related mycotoxins produced by fungus i.e. Aspergillus flavus. Twenty seven isolates of A. flavus designated as Af-1, Af-2, Af-4, Af-5, Af-7, Af-9, Af-11, Af-12, Af-13, Af-15, Af-25, Af-28, Af-31, Af-33, Af-34, Af-35, Af-36, Af-37, Af-39, Af-40, Af-46, Af-47, Af-54, Af-55, Af-58, Af-59 and Af-60 were collected from different agro climatic conditions from chilies (Capsicum frutescence) samples. Random amplified polymorp...

The changes of chlorophylls and main metabolites in three cultivars of Triticum
aestivum L. under the effects of osmotic and lead stresses, as well as their
interaction, were investigated. The results indicated that, the decreased Ψs and Pb concentration caused an increase in the chlorophyll content in
all plants. Conversely, the chl. a/b ratio was decreased.
Apparently, the total soluble proteins were increased in response to low ...

Proper vernalization temperature of mother onion bulbs stimulates early
flowering and produces a heavier yield of seed. Moreover, onion cultivars seem
to differ in their optimal temperature requirements depending on the locality
to which they are adapted. Most studies on the effects of storage temperature
on inflorescence initiation in onion have shown that the optimum temperature
for flowering is in a range between 5℃ to 13℃ for 90 to 120 days and
bolting resistant varieties require a longer co...
