Effects of surface and subsurface drip irrigation regimes with saline water on yield and water use efficiency of potato in arid conditions of Tunisia
Field experiments were conducted on a sandy soil during spring of 2009
and autumn of 2010 in southern Tunisia for evaluating the effects of two drip
irrigation methods and three irrigation regimes on soil moisture and ...
Is long-term protection useful for the regeneration of disturbed plant communities in dry areas?
In dry areas, natural plant communities are mainly affected by climatic stress and human disturbances – overgrazing, ploughing and biomass harvesting – that accelerate their degradation. Management techniques, including ...
Vers une gestion durable et une gouvernance soutenue des parcours du sud de la Tunisie
La présente note de politique synthétise et capitalise sur les acquis des recherches socioéconomiques entreprises par les chercheurs de l’IRA et de l’ICARDA sur la gouvernance des parcours au sud de la Tunisie dans le cadre ...
Water users associations and irrigation water use efficiency in costal oases areas of Gabes, South-eastern Tunisia
The objective of this study was to measure the efficiency level of Water Users Associations (WUAs) in the coastal oases of Gabès (South-Est of Tunisia) and assessing its main determinants. First, an input-oriented data ...
Measurement of the aboveground biomass of some rangeland species using a digital nondestructive technique
Plant biomass is usually assumed to be positively correlated with canopy cover. Measurements of
canopy cover can now be easily and precisely made through image processing of high-resolution
digital photography. This study ...
Corn Yield and Water Use Efficiency Under Contrasting Irrigation Application Methods: An Aquacrop Study Contrasting Subsurface Drip and Sprinkler Irrigation Methods.
Grain corn (Zea mays, L.) is sensitive to soil water availability, which can be influenced by irrigation application method. Four facts
motivate deficit irrigation of corn in this region. First, declining Ogallala aquifer ...
Food Value of Soft Dates Cultivated in Tunisian Coastal Oases
Maintaining bio-diversity in Tunisian oases has become a subject of first interest in date palm cultivation in Tunisia.
Coastal oases still retain a very rich and varied plant biodiversity in comparison with the continental ...
Modelling water-harvesting systems in the arid south of Tunisia using SWAT
In many arid countries, runoff water-harvesting systems support the livelihood of the rural population. Little is known, however, about the effect of these systems on the water balance components of arid watersheds. The ...
