Abstract
A post experiment was carried out on wheat plant (cultivar – Sham 6) during the agricultural season (2018) at the laboratory of the Department of Soil and Land Reclamation / Faculty of Agriculture / University of the Euphrates. Three levels of irrigation water (1.10, 3 and 6 m/ds) were used which w1, w2 and w3, respectively, and three levels of sheep manure (0, 30 and 60) tons / ha which coded (M0, M1 and M2), respectively, with three replications, thus becoming 27 experimental units, a factorial experiment was arranged according to split plot design. Irrigation was carried out according the treatments of the study, and the moisture content continued to attained the level of (75-80)% of the ready water by weight for all treatments throughout the study period, and the washing requirements were added by (15)% with irrigation water, and on the date of 10/5/2019 . the plants of all treatments were harvested. The results showed when:
The salinity of the irrigation water increased it caused a significant increase in the values of electrical conductivity, soil organic matter, and the ratio of adsorbed sodium (SAR), and a decrease in pH, while increasing levels of sheep manure contributed to a decrease (electrical conductivity, pH, and (SAR) and increased soil content of organic matter. The overlap between sheep manures and the salinity of the irrigation water that achieved in the characteristics of (plant height, number of branches, weight of dry matter, and weight of 1000 grains of wheat (cultivar sham- 6) the lowest values as they reached (73.25) cm (3.55), (28.54) g and (38.11) g, respectively, for the treatment (W3M0) and the highest values, as it reached (86.15) cm, (6.73), (38.36) g, and (43.56) g, respectively, for the treatment (W2M2) .
Key words: irrigation water quality, sheep manure, soil salinity, wheat (cultivar cham 6).
