Water supply efficiency of brought for phenological stages on a few morpho-physiological parameters of the durum wheat (Triticum durum Desf.)

摘要

Our work consists in quantify the benefits effects of a water supply brought to different phenological phases on the durum wheat yield and morpho-physiological traits associated to it. For this purpose, two tests are performed in the field: the first conducted under rainfed conditions and the second with the addition of water at 50 mm tillering and heading, and 60 mm during the filling phase grain. Results obtained for first trial confirm poor performance in the rainfed treatment compared with the irrigated treatment for all measured characters. However, the effect is more or less significant, depending on the caseon account of difference of the period for elaboration of each component of yield.
