Innovation Platforms in Agricultural Research for Development: Ex-ante appraisal of the purposes and conditions under which innovation platforms can contribute to agricultural development outcomes
Innovation platforms are fast becoming part of the mantra of agricultural research for development projects and programmes. Their basic tenet is that stakeholders depend on one another to achieve agricultural development ...
Exacerbated grassland degradation and desertification in Central Asia during 2000–2014
Grassland degradation and desertification is a complex process, including both
state conversion (e.g., grasslands to deserts) and gradual within-state change (e.g., greenness
dynamics). Existing studies hardly separated ...
First detection and molecular identification of Neospora caninum from naturally infected cattle and sheep in North Africa
Neosporosis, caused by the protozoan Neospora caninum, is a major cause of reproductive failure in ruminants causing enormous economic losses. The objective of this study was to estimate the infection rate and molecular ...
Laser-land leveling adoption and its impact on water use, crop yields and household income: Empirical evidence from the rice-wheat system of Pakistan Punjab
Using a primary dataset from 350 farmers from the rice-wheat area of Pakistan Punjab, we estimate the impact of laser-land leveling on water saving, crop yields and household income. The analysis employs propensity score ...
Simple and robust model to estimate live weight of Ethiopian Menz sheep
Abstract. Heart girth (HG) bands have been predominantly used in Ethiopia by smallholder
farmers, traders and extension workers to estimate live weight (LW) of livestock. They are
produced using recommended and published ...
Representation of decision-making in European agricultural agent-based models
The use of agent-based modelling approaches in ex-post and ex-ante evaluations of agricultural policies has been progressively increasing over the last few years. There are now a sufficient number of models that it is worth ...
Performance Evaluation of an Off-road Light Aerial Platform for Date Palm Cultivation
Date palm (Phoenix dactylifera L.) cultivation is characterized by several operations performed at the frond level. Fronds can be many meters above the ground, especially in older groves or plantations. Mechanization in ...
Phenotypic, host range and symbiotic characteristics of indigenous soybean nodulating rhizobia from Ethiopian soils
Soybean is an exotic crop to Ethiopia and may not necessarily have a specific endosymbiont in the soil. However, since it is a promiscuous host, nodulated by cross nodulating rhizobia, it is likely that some compatible ...
Heat-Tolerant QTLs Associated with Grain Yield and Its Components in Spring Bread Wheat under Heat-Stressed Environments of Sudan and Egypt
Heat stress decreases photosynthesis, pollen viability, grain number and weight, and hence lowers yield and quality of wheat by variable amounts among different cultivars and genotypes. The present study was carried out ...
Evaluation de la biologie du sol sous l’effet du traitement chimique en semis direct dans une zone semi-aride de l’Algérie
En tenant compte du rôle des microorganismes dans la préservation de l’écosystème agricole, un essai expérimental a été suivi pour évaluer l’effet du semis direct sur l’activité des microorganismes dans un sol céréalier ...
