Barley and Vetch yields from dryland rotations with varying tillage and residue management under Mediterranean conditions
With increasing land-use pressure in semi-arid, dryland Middle Eastern agriculture, fallow-based cereal production has given way to cropping intensification, including legume-based rotations along with conservation tillage ...
Nitrogen mineralization potentials of selected mediterranean soils
To gain a better understanding of N availability in Mediterranean soils, 18 surface (0–20cm) soil samples were selected from soil groups of Syria for study of their N mineralization potentials. The chosen soils represented ...
On-Farm Assessment of Improved Crop Production Practices in Northwest Syria. I. Chickpea
Thirty on-farm trials were conducted in northwest Syria over a period of four seasons to examine the main effects and interaction of sowing date, sowing method, Rhizobium inoculation, phosphate application and weed control ...
Implications of cereal-based crop rotations, nitrogen fertilization, and stubble grazing on soil organic matter in a Mediterranean-type environment
Soil organic matter (SOM) is essential to all soil processes that have an impact on crop production and the environment. Soils of the semi-arid Mediterranean region are low in SOM due to environmental conditions (temperature, ...
Assessment of the Effects of Environmental Factors on the Response of Wheat to Fertilizer in On-farm Trials in a Mediterranean Type Environment
A series of researcher-managed wheat fertilizer trials was conducted on representative farmers fields across northwest Syria between 1986 and 1990. Wheat grain and straw yields were strongly correlated with seasonal ...
Nitrate‐n test as a guide to N fertilization of Weat in the mediterranean region
Forty factorial experiments with 4 levels of N (0, 40, 80, and 120 kg N/ha and 4 levels of P (0, 8.8, 17.5, and 35 kg P/ha) with two replicates were conducted in farmers’ fields during two consecutive seasons in 1987 and ...
Modification of the FAO‐56 spreadsheet program for scheduling supplemental irrigation of winter crops in a Mediterranean climate
Population growth and urbanization are increasing demands on limited renewable water resources in the
Mediterranean region. Irrigation is a major water user, and so there has been increased effort to improve its efficiency. ...
On-farm Assessment of Improved Crop Production Practices in Northwest Syria. II. Lentil
The production of lentil (Lens culinaris) was examined in 24 on-farm trials conducted over three seasons (1985/86 to 1987/88) in northwest Syria to examine the main effects and interaction of sowing date, weed control, ...
Long-Term Cereal-Based Rotation Trials in the Mediterranean Region: Implications for Cropping Sustainability
With increasing global populations particularly in developing countries, and a limited or even shrinking supply of arable land, the challenge to agriculture is to meet the world's food and fiber needs without reducing the ...
Modification of the FAO-56 spreadsheet program for scheduling supplemental irrigation of winter crops in a Mediterranean climate
Population growth and urbanization are increasing demands on limited renewable water resources in the Mediterranean region. Irrigation is a major water user, and so there has been increased effort to improve its efficiency. ...
