EFFECT OF FOLIAR APPLICATION OF CALCIUM NITRATE AND POTASSIUM NITRATE ON MICRONUTRIENTS AMOUNT OF TARRAGON IN “RAY” REGION
تاثیر محلول پاشی نیترات کلسیم و پتاسیم بر میزان ریزمغذی در ترخون
Abstract


The effect of foliar applications of Ca(NO3)2 and KNO3 on micro elements composition of leaf was investigated. The experiment was conducted in 2010 in Rey, Tehran, Iran using Complete Randomized Block Design with three replications. Both fertilizers had four different levels (0, 1.5, 3 and 6 gram Per Lit). Tarragons were sprayed tree times starting at 30 days after cutting in 20 day intervals. Contents of micronutrients of leaf were determined by atomic absorption and spectrophotometric method. Results showed that Ca(NO3)2 and KNO3 had a significant effect on all of the mineral content of leaves. The highest values of Cu, Mn, Zn and Fe were obtained from 3 grams Per Lit Ca(NO3)2 than other treatments, but the higher content of Mg observed in 1.5 grams Per Lit Ca(NO3)2 applications. In the case of KNO3, the higher accumulation of Fe, Zn and Mn obtained from 6 grams Per Lit KNO3. 3 grams Per Lit foliar KNO3 applications caused the higher contents of Mg and Cu in tarragon leaves. The interaction effect of Ca(NO3)2 and KNO3 applications was significant for all of micronutrients [1- 3].
