Abstract

For study the effects of different levels of irrigating according to the 0, 25, 50 and 75% of field capacity to the amount of food less demand’s elements in the number of 5 and Rapeseed (Brassica napus) line this experiment randomized complete block design had been executed in the field at 2002-2003 in the research field of agricultural university of Varamin, Azad University. The amount of the needed fertilizer had consumed according to the soil analysis of the test site. At the end of the research for determining the amount of each element in each caring, the leaf samples had transferred to the laboratory and the necessary examination had been performed. The result had been Variance analyzed with the help SAS software and the comparison of the data average had executed with the help of the multi amplitude test of Duncan. According to the results of Variance analysis, the difference of elements in the numbers and different lines of Rapeseed (Brassica napus) and the different levels of irrigating and the counter effect of these two factors had been meaningful in the level of 1% and among the numbers only the element of Sulphur had the statistical meaningful difference. The variety of Hyola-42 and Mohican had allocated the first and the last statistical class to itself orderly with the average of 1.94 and 1.03%. The varieties were not meaningful in the case of the amount percentage of boron and Zn in the dry substance of leaf. Also in this study the different levels of irrigation has been meaningful effects on the amount of percentage of the elements 3. With increasing of the intensity of drought stress from 75-0% the F.C amount of element have shown the decreasing amount and Sulphur had reached from 1.98-1.01% and the Zinc had reached to the 15.2 mg from 29.6% in the dry substance of the leaf. However the amount of the results had shown the reduction but they were meaningless in the case of statistic.
