A field experiment was conducted during the agriculture season (2014 -2015) In Horticulture station of the Ministry of Agriculture in Mahaweel which located 20 km north of Babylon city in sandy clay loam soil , usinga randomized complete block design (RCBD) with Systematic Arrangement of Whole – plots , to study the Effect of irrigation water quality and organic and mineral fertilization on the availability of some nutrient elements and cabbage yield , The experiment included 72 Treatment caused by the interaction between the two factors , The first factor represents the salinity results of the study Summarized as follow : The raised of water salinity levels led to significantly raise the values of electrical conductivity of the soil and nutrient elements availability (N, P and K) in the soil and A slight decrease in the PH and cabbage yield .

While adding organic fertilizer led to a significant decrease in the electrical conductivity of the soil and PH , Also led to a significant increase in the nutrient elements availability (N, P and K) in the soil and cabbage yield .

Mixing compost + Chemical fertilizers has led to a significant increase in available N and P in the soil , and yield Compared with the addition of each of them individually .

The mixing treatment ((Composting corn cobs + composting cattles 20 tons h-1 rate of 1: 1) + Chemical fertilizers)) outperformed on other treatments to give the highest yield values reflected significantly on the product of cabbage (60.92 ton h-1 ) .

of irrigation water (W) at three levels (1.4, 3 , 6 ds m-1 ) The second factor represents the organic and mineral fertilization (T) with eight in fertilizer transactions which are ( Control ) , (Composting corn cobs 20 tons h-1) , (Composting Cattle 20 tons h-1) , (Composting corn cobs+ composting cattles 20 tons h-1 ratio of 1: 1) , (Chemical fertilization) , (Composting corn cobs 20 tons h-1 + Chemical fertilization) , (composting cattles 20 tons h-1 + Chemical fertilization ) , ((Composting corn cobs + composting cattles 20 tons h-1 rate of 1: 1) + Chemical fertilization) ) .

with three replicates .
