| Abstract | ||
| The Experiment was carried out in wire house at private farms near Mussayab Technical Institute during the autumn growing season 2009-2010 for corn crop Zea mays L . The study included eighteen treatments are consisting of the compatibility between two factors. First, was two kinds of soils: sandy and loamy clay soil . second was nine levels of irrigation water(1- river water, 2- drainage water collected in winter season, 3- drainage water collected in summer season, 4-one irrigated from drainage2 followed with one river irrigated, 5- two irrigated from draing2 followed one river irrigated, 6- two irrigated from draing2 followed two river irrigated,7- one irrigated from drainage3 followed with one river irrigated, 8- two irrigated from drainge3 followed one river irrigated, 9- two irrigated from draing3 followed tow river irrigated . The RCBD with three replicate was used and the means was compared by L.S.D 0.05. The treatments of loamy soil was best than sandy soil in physical properties (bulk density, porosity and WHC) by 9.93, 27.07, and 56.61 % respectively. The treatments irrigated by river water has the best quality in this properties followed by the treatments irrigated by river water with draing2 water. The treatments of loamy soil shows an affect on chemical properties ( Ec , Ph and CEC) compared of sandy soil by 9.26 , 1.57, 35.31% respectively . Also the treatments irrigated by river water and by river water with draing2 water lead to increased the Ec and CEC and decreased the pH . The treatments planted in loamy soil showed superior qualities of the vegetative mass (germination ratio, area of leafs and dry vegetative weight) by 9.06, 4.9, 12.38 % respectively. The treatments irrigated by river water has the best quality in this properties followed | ||
