Total Dray Matter (TDM), Photosynthetically Active Radiation Intercepted (PARabs), Water Consumption (WC), Water use-(WUE), Radiation use efficiency (RUE) and the relationship between Radiation Interception and Water Consumption for Durum Wheat were investigate under different irrigation amount (D 1 = 100 % ETc; D 2 = 70 % ETc; D 3 = 40 % ETc and D 4 = pluvial) and during three growing seasons (2005-2006, 2006-2007 and 2007-2008). Results showed that, the cumulative PAR abs decreased with deficit irrigation. In fact, D 1 treatment recorded the highest cumulative PAR abs and the lowest marked underD 4 treatment. Similarly, TDM and RUE were decreased with deficit irrigation. The highest RUE observed under the D 1 (from 1.32 to 1.43 g MJ -1 ) and the lowest under D 4 (from 1.17 to 1.29 g MJ -1 ). However WUE increased with deficit irrigation. The highest WUE were obtained under the D 4 (from 3 to 4 kg m -3 ) and the lowest were observed under D 1 (from 2.8 to 3.1 kg m -3 ). Significant linear relationship was found between cumulative PAR abs and cumulative water consumption with a high correlation coefficient (R 2 ) only under the two treatments D 1 and D 2 .

“…Il faut noter que si pour certaines espèces, comme les cultures annuelles, essentiellement les céréales, les données sont plus ou moins disponibles, pour d'autres espèces, comme les légumineuses ou les arbres fruitiers, les données font défaut (Katerji et al, 2008), ce qui traduit, à notre sens, le peu d'intérêt porté à la problématique de l'EUE en agriculture, surtout dans les pays du Maghreb. Un effort doit être consenti pour contribuer à trouver des solutions efficientes à la pénurie des ressources en eau dans ces pays.…”

L’eau, en tant que ressource, est un bien très important et surtout fondamental pour tous les pays. En effet, en plus d’être indispensable à la vie et à la santé de l’être humain, l’eau est un vecteur du développement socio-économique. Le présent ouvrage, publié par le Bureau Multipays de l’UNESCO à Rabat, regroupe les expériences de plusieurs spécialistes en eau de la région du Maghreb. L’objectif d’un tel ouvrage est de faire partager le vécu des différents experts des pays du Maghreb et de rassembler les visions de chacun pour permettre de propager de nouvelles idées visant un meilleur système de gestion de l’eau au Maghreb.

Effective use of rainfall water is a key issue in agricultural development in the arid and semi-arid regions since rainfall water is a precondition for crop production there. This study was conducted in a semi-arid agricultural region with 900 km 2 in area in Hashtroud, northwest of Iran to determine the relationship between rainwater use efficiency (RWUE) and soil properties. Winter wheat yield and soil properties were determined at 108 plots (40.41 m 2 in area) installed in thirty six dry-farming lands. RWUE of each plot obtained from the ratio of crop dry matter per unit of abstracted rainfall water volume (ARWV). ARWV was computed from deduction of the rainfall and runoff volume during a two-growth period. Runoff data for each land was obtained from field measurements at the plots under natural rainfalls. Analysis of rainfalls uniformity using four rain gauge stations data showed that spatial distributions of rainfalls were homogeneous in the area. The RWUE values in the lands were ranged from 0.35 kg m -3 to 1.49 kg m -3 with an average of 0.84 kg m -3 . Soil properties which considerably affected either the infiltration capacity or the available water controlled the RWUE in the study area. Multi-regression analysis indicated that the RWUE significantly related to silt, organic matter and lime (R 2 =0.82, p < 0.001). Maintaining crop residues and incorporating with the soil can be proper techniques and sustainable strategies to improve the soil properties and enhance the RWUE in the dry-farming lands.
