Assessment of woody species diversity, key drivers of deforestation and community perception; the case of Hotessa Forest, Bensa Woreda, Sidama Zone, Southern Ethiopia

In Ethiopia, deforestation is a major challenge which leads to increased human encroachment upon wild areas and threats to biodiversity. In line with this, the aim of the current study was to assess woody species diversity and threats in Hotessa forest. Systematic sampling method was used to collect vegetation data. Accordingly, 100 plots each with 400 m2 (20 m × 20 m) for...

Grain yield and protein content of upland rice (Oryza sativa L.) varieties as influenced by combined application of primary secondary and micronutrients under Nitisols

Field experiment was conducted on Nitisols to evaluate the effects of combined application of primary, secondary and micronutrients on grain yield and protein content of upland rice varieties compared to the national recommendation. Factorial combination of five nutrient combinations (control, NP, NPK, NPKSZn and NPKSCaZn) and three upland rice varieties (Nechu Eruze, Superica-1 and NERICA-4) were laid out in a...

Standard heterosis and trait association of maize inbred lines using line x tester mating design in Ethiopia

Maize is one of the high priority crops to feed the ever increasing population in Africa, however, its production limited by shortage of high yielding variety coupled with biotic and abiotic stresses. The study was initiated to evaluate the heterotic performances of the F1 hybrids over the standard checks (Kolba and Jibat). Fifty entries consists 48 F1 single crosses developed from 24 inbred lines and 2 testers using...
