چکیده مقاله :
Abstract Salinity is one of important stresses that limit agricultural production. Salinity is influence on the plant growth through effect on more physiologic and morphologic activities. For this purpose, an experiments were conducted to evaluate the effect of salinity due the sodium chloride on the amount of Potassium (P), Magnesium (M), Calcium (Ca) and Phosphorus (P) in mustard, at the farm of the Islamic Azad University of Mashhad Branch, Iran, in 2012. It was carried on the randomized complete block design with three replications. Desired test performed in the lysimeters. In this experiment was used 12 cylindrical polyethylene lysimeters and was applied four treatments with various degrees of water salinity: 0, 2, 4 and 6 ds/m (water wells) each one with 3 replications. Remarkable note that the above-mentioned treatments was conducted after the initial stage of growth, so that after planting (8-leaf stage) until germination and early growth were used well water for irrigation in all the 12 lysimeters. The results showed that increasing salinity levels was significantly reduced amount of potassium, magnesium, calcium and phosphorus. Keywords: salinity stress, irrigation, potassium, calcium, phosphorus, mustard and magnesium.
