Field experiment was conducted during the season (2011-2012)at Bhanine village in Tartous city. Maize seeds of Ghouta 82 variety were planted in plastic pots filled with calcareous soil .Treatments including three levels of B( 0 , 3 , and 6 kg.ha-1)
as boric acid form and four levels of Zn (0 ,8,16 and 24 kg.ha-1) as zinc sulphate form added to the soil when it was preparation to farming , in a completely randomized block design with three replications, to study the effect of different levels of boron and zinc and their interactions on Maize growth and its contents of some nutrient elements . the readings that was taken plant length leaf area index ,wet and dry weight for plant in three growth stage: vegetative growth , start and end of flowering , stage , and evaluation concentration of N ,P , K ,B , Zn,Mn,Fe,Cu nutrients in the leaves at the back stages, in addition at havest stage.
A field experiment was conducted in Tartous Governorate, on
the Arachis hypogaea . L during tow growing season (2012-
2013)(2013-2014). Experiment was included 6 treatments with
three replicates: control (without fertilization), different rates of
Olive Mail Waste Water (OMWW) (5-10-15) l/m2 , organic
fertilizer (30 tn/h)and nitrogen fertilizer(30)kg/h.
The research aimed to know effect of these Additions on some
physiological groups of microorganisms, nodulation on plant
roots and nitrogen relative bacteria Arachis hypogaea . L. yield.
