Today with regard to environmental pollution caused by chemical fertilizers and finding an alternative to these fertilizers, Consideration has been given to the use of other products in this field. Accordingly, In order To study the effect of Nano calcium and Humi potas on morphological and biochemical traits of nasturtium, this factorial experiment was conducted in a randomized complete block design with 3 replications. The experiment was carried out at Shahid Chamran University of Ahvaz in 2013-2014. In this study, morphological traits, length and diameter of stem, number and leaf area, number of lateral branches, number of flowers and seeds, fresh and dry weight of leaves, stems and roots and biochemical traits, total chlorophyll, calcium and potassium absorption Evaluated. The results showed that the interaction of two treatments in all studied traits, except for stem length and diameter, number of flowers and number of branches, was significant. According to the results of the best condition in the studied traits, we observed interaction effects of concentration of 2 in 1000 Nano calcium with 500 and 1000 ppm Humi Potasses. Both treatments had a non-significant difference and Showed a significant difference compared to control treatment. In general, the application of concentration of 2 per thousand Nano calcium with different levels of Humi potash fertilizer improved morphological and biochemical traits in Nasturtium flowers.
