Twenty lambs (18 ± 0.22 kg initial weight) were blocked by weight and individually assigned into pens to evaluate the effects of barley straw variety on digestibility, growth performance and carcass characteristics. The following four treatments were...
Even though host plant resistance has long been recognized as the foundation of integrated pest management, research in North Africa, West and Central Asia only started in 1980. The recent use of Focused Identification of Germplasm Strategy has...
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...
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

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 challenging...
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 biophysical...
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...
