Effect of water regime with different kinds of fertilizers on Salvia officinalis ,L. plants grown in sandy soil, under drip irrigation system [electronic resource].

Two field experiments were conducted in Aly Mubark experimental Farm in sandy soil at EI-Bustan Sandy soil irrigated by drip Irrigation, during 2003 and 2004 seasons. The experimental aimed to study the effect of three Irrigation treatments with three different kinds of fertilizers and Its concentration on sage growth, yield, essential oil yield and components, macro-nutrients content In dry herb as well as water use efficiency and to develop crop coefficient or sage plants under drip irrigation system at EL-Bustan area in Nubaria region. Split-split plot design was used in these experiments. The main plots contained of the three drip irrigation treatments (water regime) (120, 100 and 80% of potential evapotranspiration (ETp) were determined using class A pan). Sub plots were occupied by three different kinds of fertilizers, the first was a mineral fertilizer as a mixture of N, P and K, 70 kgN/fedd (as ammonium sulphate 20.6%), SO kg Pz0slfed. (a8 a calcium super phosphate J!5.S%) and 72 K2O/fed (a8 a potassium sulphate 48%). The second was a biofertllizer added as Nltrobein and Phosphorein (1: 1 ratio). The third was an organic fertilizer used as a Farm Yard Manure (FYM) at rate of (30 m3/fed.). Sub-sub plots were occupied by two rates of fertilizers (with and without fertilizers) i.e fertilized and unfertilized plants (control treatment).
