ABSTRACT Ethiopia has wide eco‐environmental diversity ranging from extreme heat at one of the lowest places in world to coolest summits Africa. Associated with this environmental and climate change, climatic extremes are expected change over time also vary across eco‐environments country. This study was conducted examine trends past precipitation temperature three Ethiopia. The involved analysis 20 indices computed daily data spanning 42 years (1967–2008). were obtained 11 stations selected...
We assessed land use/land cover changes from remotely sensed satellite imagery and compared this with community perceptions on availability/use of livestock feed resources deficit management strategies since the 1973s in three districts representing pastoral, agro-pastoral mixed crop-livestock eco-environments Ethiopia. found that are proceeding all transitions grasslands, forest lands to bush/shrub crop pastoral site (Liben), grasslands (Mieso) lands, (Tiyo). The significantly affected...
Abstract In Ethiopia, the use of traditional and improved grain sorghum [ Sorghum bicolor (L.) Moench] variety as green forage crop is limited mainly by large stalk thickness low nutritive values. An experiment was conducted to explore if biomass accumulation values could be managed seeding rates. Two dual‐purpose varieties (Melkam Chelenko), one local (Masugi) each representing early late maturity groups were sown for 2 yr at three locations in randomized complete block design (RCBD) with...
Global warming is forcing plant and animal species to respond either through pole-ward or upslope migration adjust temperature increases, grassland communities are not an exception this phenomenon. In study, we modeled the response of herbaceous grasslands within Arsi Mountains in Ethiopia under no-migration with scenarios projected 4.2 °C increase by 2090 (under A2 emission scenario). For 67 grasses legumes, determined current predicted altitudinal limits calculated area coverage using a...
Abstract An experiment was conducted to evaluate the effects of row spacing (RS) and interplant (IPS) on yield total biomass, leaf, edible twigs, nutritive value pigeon pea ( Cajanus cajan L. Millsp.) at three locations in Rift Valley area Ethiopia. The authors used a randomized completed block design with replications 3 × factorial arrangement: RS (25, 50, 75 cm) IPS (15, 30, 45 cm). Row 25 30 cm 50 15 gave greater biomass than other combinations. A similar result found for plant yield. At...
Lablab is one of the conventionally grown multi-purpose crops that originated in Africa. It an annual or short-lived perennial forage legume which has versatile uses (as a vegetable and dry seeds, as food feed, green manure) but yet to receive adequate research attention hence remains underexploited. To develop new highly productive lablab varieties, using genomics-assisted selection, present study aimed identify quantitative trait loci associated with agronomically important traits assess...
Abstract Background In Sub-Saharan Africa (SSA) livestock production and productivity are severely restricted by the scarce supply of feedstuffs forage crops, while those available often low nutritional quality resulting in poor animal leading to widespread malnutrition among public, particularly women children. Traditionally, several tropical crops have been used region both rangelands as cut-and-carry cropping systems, but limited research attention has paid improve access these feeds....
<p><strong>Background.</strong> In mixed crop livestock farming systems in Ethiopia, sorghum stover and other residues are a strategic feed resource. Farmer’s decisions intensity of use for than uses closely associated with biophysical socioeconomic characteristics. <strong>Objective.</strong> This study explores determinants biomass three major growing agroecological zones Ethiopia. <strong>Methodology.</strong> Tobit double hurdle models were run...
