Abstract: Two field experiments were carried out during two successive seasons of 2009and 2010 to study the effects of organic manure application and soil type irrigated with drainage water on growth, oil yield and its nutrients component of sunflower (Helianthus annuus L.), variety sakha 53. A field plots experiment were conducted in Senores, Al-Bouhira governorate, sex plots (separated to three control and another three fertilized with organic manure at rate 10 m3/fed-1) represented three different soil type on the base of normal, alkali saline and saline soil. In absence of organic manure, obtained results show that a significant decreases in the growth parameters (plant height, stem and head diameter, number of leaves, leaf area index, weight of 100 seeds, seed yield/plant and seed yield kg/fed), as well as oil % and oil yield kg/fed and nutrients composition in both leaves and seeds (N, P, K, Fe, Mn and Zn) were noticed due to saline irrigation water and soil type, particularly in saline soil for plant growth and both oil% and oil yield kg/fed as well as in alkali saline soil for nutrients composition. Positive effects of organic manure on plant growth parameters, both oil% and oil yield kg/fed and nutrients composition were observed and/or decreased the adverse effects of salinity of both soil and drainage water on vegetative growth as well as on the yield of sunflower.
