Apport hydrique et son impact sur le comportement de quatre variétés de haricot bio fortifié dans le groupement de Buzi

In order to determine the water intake positively impacting the behavior of each of these four warieties of forti fied organic beans « RWR10, HM21-7, NUA100, CODMLB001 » subjected to the analysis, the following experiment was carried out. Beforesowing, the starting humidity was determined by drying the soilsample in the sun for 72hours,followed by the determinetion of the daily requirement by the parameters of permeability and hydraulic conductivity which served as a quantification of the water lost by percolation, to maintain the quantity available to the plant.
