|Title:||DYNAMIQUE DU PHOSPHORE DANS LE SYSTÈME SOL-PLANTE (CAS DU BLÉ DUR) EN CONDITIONS AGRO-CLIMATIQUES SAHARIENNES|
|Series/Report no.:||volume 2 numéro 2 2012;|
|Abstract:||This experiment is part of a research program on the fertilization of durum wheat grown under center pivot in Saharan soil and climatic conditions. This work research for the type of phosphorus fertilizer (MAP, Fosfactyl and SSP) and dose (30, 60 and 90 units/ ha) to suggest in these conditions and appreciate the influence of phosphorus fertilization on of nitrogen exportations. The principal results demonstrate that the behavior of culture varies with the nature of the phosphorus fertilizer used. So the economic parameters and quality of the product will specify the dose and the type of fertilizer to be used; the maximum yield is approximately 6,9 t.ha-1 was obtained by the interaction Fosfactyl*(60 P2O5.ha-1 units). The yields are very strongly related to potash exports by the crop, and increase according to the quantities of exported K2O (R =0.82***).|
