Biological effect of gamma irradiation on vegetative propagation of Coffea arabica L

Coffee is the second most valuable commodity exported by developing countries, and supports the livelihood of more than 75 million people. There are limitations to preference for established cultivars due to the autogamous nature of the crop thereby making improvements via conventional breeding of many years to produce a new cultivar difficult. Mutation breeding can overcome these obstacles. One of the first steps in...

Response of onion (Allium cepa l.) to deficit irrigation under different furrow irrigation water management techniques in Raya Valley, Northern Ethiopia

Scarcity of water is the most severe constraint for development of agriculture in arid and semi-arid areas. Under this condition, the need to use the available water economically and efficiently is unquestionable. Based on the actual crop need, irrigation management has to be improved so that the water supply to the crop can be reduced while still achieving high yield. A field experiment was carried out at Mehoni...

Comparative study on the effect of bio-slurry and inorganic N-fertilizer on growth and yield of kale (Brassica oleracea L.)

Kale is one of the nutritious leafy vegetables with a high nitrogen fertilizer requirement. However, soil fertility is declining progressively due to the imbalanced use of inorganic fertilizer. Discharging bio-slurry as waste will lead to environmental pollution and disposing will also lead to costs because of its large volume. Consequently, replacing chemical fertilizers with bio-slurry can not only achieve efficient...
