| Abstract | ||
| In Hartha Research and Experimental station, College of Agriculture – Basrah University (35)Km northen –east of Basrah city . An experimental field was conducted in soil (clayey silt –silty ) cultivated with two crops , wheat .Triticum aestivume ,and Barley Hardem Vulgare L. To Know the roles of these Crops to get recently reclaimed soil better properties .The method used is the Factorial Experimental Design with completely Blocks Randomized, with two factors ,the first (A) has six levels as follows : A1(0-15)cm , a2(15-30)cm , a3(30-45)cm , a4(45-60)cm, a5(60- 90)cm , and a6(90-120)cm The second factor (B) have seven levels that as follows : B1(Gypsum) , b2(Lime) , b3(Total nitrogen) , b4(Organic mater) , b5(SAR) , b6(ESP) and b7(PRI).The Blocks represent three states: R1(pre-cultivation) , R2(Past-wheat cultivation ) , R3(Past-Barley cultivation). After complying collected data , and applying the statistical analysis with Correlation Coefficient to know the significant effect between wheat and barley and among chemical indications and compounds show : 1-Soil depths which represent first factor have not significant differences on all the chemical indicators and compounds. 2-Crops type shows highly significant effects for barley when compared with part-wheat cultivation and pre-cultivation. 3- Planting barley shows good Correlation Coefficient which are in agreement with natural Correlation that fit to the gighly standards which emphasizes the role of the grops in promoting Characteristics of the soil compared with the condition of planting wheat particularly with Gypsum ,Lime , Nitrogen total , Organic mater . | ||
