Journal Title: International Research Journal of Applied and Basic Sciences - Year 2015, Vol 9, Issue 1
Abstract
The effects of soil application of humic acid and fulvic acid on some Physiological properties of Citrus sinensis cv.Thomson plants grown at various lime conditions were examined. Lime concentrations were 0, 15 and 30%. The liquid humic acid and fulvic acid were put into the soil pots three times on15,30 and 45th day after bud emerged. The application doses of humic acid and fulvic acid were 0, 50 and 100m g/l. Each application consists of four replications. The experiment was conducted in Pot experiment under controlled conditions in completely randomized factorial design in mazandaran. The interaction effect between lime & spray for Mn was found statistically significant (P < 0.05) and the interaction effects between lime & spray for Zn, Fe and Cu was found statistically significant (P < 0.01) (table1). According to the analysis results, the most measurement of Mn, Zn, Fe and Cu in the level of lime (0%) and the least measurement of Cu by the level of lime (15%) and Mn, Zn, Fe by the level of lime (30%) obtained (table2).
