  To evaluate the effect of previous crop, N rate and N split application on rice (Oryza sativa L. cv. Hashemi) growth and paddy yield, a field experiment was conducted at Sowma'ehSara, Guilan province, in 2014 as a split-factorial arrangement based on Randomized Complete Block Design with three replicates. Main plots were previous crop [Berseem clover, faba bean, and control (fallow)] and subplots were the factorial arrangement of N rate (50, 75, and 100 percent of N recommended rate which was 50, 75 and 100 kg Urea ha-1, respectively) and N split application (100 percent at transplanting stage, 100 percent at tillering stage, and 50 percent at transplanting stage and 50 percent at panicle initiation). Results showed that rice paddy yield was significantly affected by previous crop and N rate, but N split application had no significant effect on paddy yield. The highest paddy yield (4142.8 kg ha-1) was obtained when rice was cultivated after berseem clover and the lowest paddy yield (3494.0 kg ha-1) was obtained when rice was cultivated after faba bean. Rice paddy yield was increased significantly by 8% as N application rate increased from 50 to 78 kg urea ha-1, but further increase in N rate (100 kg urea ha-1) had no significant effect on paddy yield. Based on the result of this experiment, the highest rice paddy (4142.8 kg ha-1) was obtained when rice was cultivated after berseem clover and N was applied at the rate of 75 kg urea ha-1.

  This research was performed in order to investigate the effect of salicylic acid and sodium nitroprusside on growth and essential elements content in spring canola under nickel stress in laboratory of Science and Research Branch, Islamic Azad University of Tehran. The interactive effects of nickel, salicylic acid (SA) and sodium nitroprusside (SNP) as a donor of nitric oxide (NO) were examined on canola (Brassica napus L. cv. PF) growth. 21-day old canola seedlings (cv. PF) were exposed to different concentrations of NiCl2 , 6H2O (0, 0.5 mM), SA (0, 0.2 mM) and SNP (0, 0.2 mM) for 10 days. Nickel toxicity symptoms such as chlorosis and necrosis were observed on leaves of Ni-treated seedlings. Treatment with Ni resulted in a decrease in fresh and dry weight of roots and shoots. Mineral elements content (Mg, Fe, Ca, P, K) extremely decreased in roots and shoots of Ni-stressed canola seedlings, while the content of N in these seedlings increased in roots and decreased in shoots. Ni was more accumulated in roots than in shoots. In Ni-stressed seedlings, application of SA or NO, especially SA+NO, improved the growth and decreased the toxicity symptoms as compared to Ni-treated seedlings. SA or NO, especially both together, considerably reduced root-to-shoot translocation of Ni and increased the content of mineral elements in roots and shoots of Ni-stressed seedlings. These results showed that SA or NO and in particular their combination, markedly reduced the toxic effects of nickel on canola seedlings by sequestration of Ni in roots and amelioration of mineral nutrition.                                                                                                    Manuscript profile

  To study the effectofNaClsalinityon theuptakeofmineral elementsindifferent organs ofeggplantthree cultivars including Jahrom landrace, Dezful slim, Indian cottage grown in outdoor conditions, an experiment was performed based ona completely randomized designwith10replications.Ten days old seedlings equal in height and stem diameter in crown area were transformed into plastic pots containing 9 kg local field soil and irrigated with tap water for 20 days. Seven salinitylevelswere used with concentrations of0, 10, 20, 40, 60, 80and100 mMNaCl.Different amountsof NaCl were added to tap waterwith electrical conductivity of219µS.cm-1 and salinity stress followed for five months. The resultsshowed that the salinity caused increasing Na+concentrationin root, shoot, and leaf and Ca2+ in roots.Moreover, thesalinitydecreased the rootpotassium, leaf calcium, and the ratio of K+/Na+ in root, stem and leaf. No significant changes were recorded in the accumulation of potassium in leaf and stem calcium in stem and nitrate in leaf. Among studied cultivars based onmeasuring theaccumulationofexcessions, the Jahromilandrace were evaluated asahighertolerancegenotype in comparison with Dezfulslim cultivar which showingthe highest sensitivity toNaCl salinity.
