Effect of Molybdenum, Phosphorus and Sulfur on Yield and Elements Content in Leaves of Wheat Grown in Saline Soil

“…The plant samples (leaves) were washed by tap water then by distilled water and oven dried at 65°C for 48 hours and grinded using a stainless steel mill. Ground plant samples powder divided into two portions, the first portion was wet digested with H 2 SO 4 -H 2 O 2 digest (Lowther, 1980) for measuring potassium by flame photometer (Jackson, 1973), nitrogen, phosphorus by spectrophotometry (Jackson, 1973) and molybdenum using thiocyanate and thioglycollic acid (Mir et al, 2012) The second portion was digested with HNO 3 -H 2 O 2 (Zheljazkov and Nielson, 1996) to determine sulphur as described by Jackson (1973).The main physical and chemical properties of the experimental soil are presented in Table (1) and the soil was saline in nature. The analysis of soil was carried out according to the methods outlined by Black (1965), The obtained results were statistically analyzed according to the analysis of variance technique and the multiple regression equations were calculated using costat software (CoHort softwere 1995).…”

“…It is a building block of protein and a key ingredient in the formation of chlorophyll (Jamal et al, 2009). The grain protein in wheat being low when S is deficient, the vegetative symptoms of S deficiency are stunting, yellowing of the whole plant and severe yellowing of the younger leaves when S deficiency is persistent (Wurst et al, 2010). Sulfur deficient plants have also less resistance under stress conditions (Doberman and Fairhurst, 2000).…”
