EFFECT OF ORGANIC MATTER AND SALINE IRRIGATION WATER ON SOME SOIL PARAMETERS AND WHEAT GROWTH

Abstract

The Factoried experiment was carried out during the agricultural season 2017-2018 in the wired House of the Soil and Water Technical College / Al-Furat Al-Awset Technical University , using Loam soil , and plastic cane . The CRD was used to study the effect of the interaction between salinity of irrigation water and organic matter on some soil characteristics and the growth parameters of wheat, the experiment included 36 treatments i,e the interaction between two factors, the first is irrigation water salinity (W) three levels (1.3, 3 and 6 dsm.m-1 ) and organic matter (O) Buffalo with four levels are compared (with control treatment), at the rate of ,quarter of the quantity, half the quantity and full quantitiy with three replicates .The results of the study showed:Increasing salinity levels of irrigation water from 10.3 to 6 dsm.m-1 led to increase the values of soil avaliability of (NPK) nutrients , so that when adding the organic matter lowored soil reaction rate, and increased nutrionts availability of NPK nutrition . The increase in the salinity of irrigation water from 1.3 to 6 dsm.m-1 led to a significant decrease in most of the characteristics of the plant studied, such as plant height , weight of 1000 seeds and other attributes as well as concentrations of NPK compared to the treatment of comparison (river water), but adding organic matter gave a significant increase in the studied plant characteristics and NPK soil availability
