Assessment of long-term protection on the aboveground biomass and organic carbon content using two non-destructive techniques: case of the Sidi Toui National Park in southern Tunisia
Long-term protection of arid ecosystems changes the vegetation and soil structures. The quantification of aboveground biomass and carbon content are among the principal indicators to evaluate these changes. Most methods used to quantify these...
Socio-economic impacts of zero and reduced tillage in wheat fields of the Moroccan drylands
Zero tillage (ZT) is recommended for dryland farming because it enhances retention of residual soil moisture. However, it is not always clear whether this translates to an economic advantage over conventional tillage, which helps in controlling...
Dynamic seed zones to guide climate-smart seed sourcing for tropical dry forest restoration in Colombia
Tree-based forest landscape restoration interventions require knowledge on the suitability and origin of seed sources and planting material. A common recommendation is to select locally sourced material based on the assumption that it is well...
Evaluation of bench terracing model parameters transferability for runoff and sediment yield on catchment modelling
Knowledge about the effectiveness of Soil and Water Conservation (SWC) interventions is a key for sustainable watershed management. Various modeling tools support the SWC assessment. However, setting the parameters for SWC works remains...
Continuous application of conservation tillage affects in situ N2O emissions and nitrogen cycling gene abundances following nitrogen fertilization
Fertilized agricultural soils can be a major source of soil nitrous oxide (N2O) emissions to the atmosphere. Conservative soil management may have the ability to reduce N2O emissions through affecting a number of Ncycling-related soil...
Chemical composition, and insecticidal activities of four plant essential oils from Morocco against larvae of Helicoverpa armigera (Hub.) under field and laboratory conditions
Aromatic and medicinal plants are a rich source of molecules with insecticidal activities against many insect pests. The present study investigated the insecticidal activities of four essential oils against the third instar larvae of Helicoverpa...
Root-omics for drought tolerance in cool-season grain legumes
Root traits can be exploited to increase the physiological efficiency of crop water use under drought. Root length, root hairs, root branching, root diameter, and root proliferation rate are genetically defined traits that can help to improve...
ICARDA's Durum Wheat Breeding Program aims to deliver superior varieties with increased yields against a backdrop of rapid climate change. ICARDA's durum wheat program also seeks to reverse the erosion of the crop's genetic diversity resulting...
ICARDA's bread wheat breeding program applies both conventional and molecular approaches to develop and distribute elite bread wheat genotypes, including shuttle breeding, doubled haploids, speed breeding, marker-assisted selection, and critical...
ICARDA is developing date palm production systems by utilizing and fine-tuning available modern technology. Current research projects are designed to address problem-solving, including crop management and protection, water and soil management...
