Effect of banana leaf pruning on banana and legume yield under intercropping in farmers' fields in eastern Democratic Republic of Congo
Banana-legume intercropping systems are commonly practiced in the highland zones of the eastern Democratic Republic of Congo to maximize land use and intensify crop production. However, banana leaves are pruned during legume intercropping to improve sunlight penetration for the legume. On-farm experiments were conducted in South Kivu province to determine the effect of banana leaf pruning on banana (Musa sp.), bush and climbing beans (Phaseolus vulgaris L) and soybean (Glycine max L) yield.
Effects of livestock feed sourcing and feeding strategies on livestock water productivity in mixed crop–livestock systems of the Blue Nile basin highlands of Ethiopia
Inefficient management and use of water is unanimously the most single constraint of agricultural production of Ethiopia. The study was conducted to assess the effect of livestock feed sourcing and feeding strategies on livestock water productivity (LWP) in mixed crop–livestock production systems of the Blue Nile Basin in Ethiopian Highlands. Three districts representing diverse agricultural farming systems were considered. Each district further stratified to different farming systems. Multi-stage stratified random sampling technique was employed to select farm households.
Effect of faba bean (Vicia faba l.)- forage inter-cropping: Benefits and trade-offs to improve feed resources in Lemo Woreda, southern Ethiopia
Faba bean (Vicia faba L.), also called ‘broad bean, horse bean’ is an annual crop, which mainly grows in the highlands of Ethiopia for human consumption. The objective of this study was to evaluate the effects of intercropping faba bean varieties with oat fodder on forage biomass, straw, grain yields, and straw quality. For the household survey 108 households (HHs) were selected from two kebeles (53 from Upper Gana and 55 from Jawe kebeles). The average HH family size, land and livestock holdings were 5.53 heads, 1.39 ha and 6.73 heads, respectively.
Effects of salinity and drought on early seedling growth and survival of Artemisia herba-alba
Seedlings of Artemisia herba-alba grown in glasshouse were watered with differing salinities (0, 150, 250 or 350 mM NaCl) and watering frequencies of 3, 7, 14 or 21 days for a period of 6 weeks. At the end of the study, plant survival, dry matter yield, biomass allocation (shoot and root), leaf area, relative growth rate (RGR), net assimilation rate (NAR), specific leaf area (SLA) and leaf area ratio (LAR) were recorded. When watered with 0 mM NaCl, Artemisia herba-alba plants had similar (P> 0.9) final dry matter weight and 100% survival regardless of watering frequency.
Effect of genetic improvement of sheep in Ethiopia: Development of a dynamic stochastic simulation herd model
A community-based sheep breeding program has been implemented in the highlands of Ethiopia to improve the body weight and reproductive performance of Menz sheep. This study adopts system dynamic methodology to develop a dynamic stochastic simulation herd model to evaluate the effect of genetic improvement and additional feed sources (forage production) on herd dynamics and profitability. The study also explores the opportunities of system dynamics approach in the context of designing breeding programs to predict annual genetic gain of traits.
