In order to determine the effect of potassium and calcium nanofertilizers on the quantitative and qualitative characteristics of Cichorium plant, a factorial experiment was conducted in complete randomized block design with 32 treatments and 3 repetitions in 2015-2016 at the Rice Research Institute of Iran (Rasht). In this experiment, the first factor, eight cultivars of Cichorium (indigenous landrace of northern Iran, Kashan, Urmia, Sistan and Baluchestan,Tilda,hickory,Orkis,Modified Hungarian cultivar) and the second factor was nanofertilizers use (nano-K chelate, nano- Full micro chelate, nano-Ca chelate (20.00), plus a zero control treatment. The comparison of the mean treatments showed that Tilda genotype with application of Nano-Ca chelate were the highest Grain yield (1462 kg.ha-1), Root yield (4114 kg.ha-1), Biological yield (7151 kg.ha-1), Inulin yield (559.7 kg.ha-1), Inulin content (13.60 %). indigenous landrace of Sistan and Baluchestan and northern Iran had the lowest grain yield (461 kg.ha-1) and the lowest amount of inulin (7.06%) without the use of nanofertilizers. The indigenous ecotypes of northern Iran, Urmia, Sistan and Baluchistan and Kashan had the lowest inulin yield without the use of nanofertilizers. Grain and inulin yieldes in nano-K chelate treatment were higher in all Cichorium cultivars compared to nano- Full micro chelate treatment. Based on the results of this experiment, it seems that with respect to inulin and root yieldes and high Nutritional, pharmaceutical and industrial value of inulin, the Tilda genotype and spraying of nanofertilizers to obtain valuable resources for the commercial production of inulin inside the country and reducing the use of chemical fertilizers.
