Lavandula stricta Del. is a native aromatic plant in Iran from Lamiaceae, traditionally used for treatment of rheumatic and stomach pain and cough. In usual agricultural systems, the purpose of using fertilizers and their combination is to obtain the highest seed yield and quality of the active substances. This study was aimed to compare the effects of nanofertilizer and fertilizer on growth indices, morphological and biochemical properties of lavender "Upright" (Lavandula stricta Del. ) regenerated from seed and tissue culture. The experiment was conducted as factorial design based on randomized complete block design with three replications and four experimental units at the research farm of Gorgan University of Agricultural Sciences and Natural Resources, during the growing season of 2016-2017. The treatments were two plants with different regeneration methods (seeds and tissue culture) and various types of fertilizers (control or no fertilizer, NPK fertilizer at concentrations of 10 and 20 kg per hectare and nanofertilizer at concentrations of 10 and 20 kg ha). The results showed that fertilizer treatments had significant effects on all measured properties except leaf area, shoot height, internodes length, shoot fresh and dry weight, 1000-seed weight and total phenol content (P<0. 01). The type of plant also caused differences in biochemical, developmental and morphological properties except shoot height, number of main stem, shoot fresh and dry weight, and 1000-seed weight. Interaction effect of fertilizer and type of plant was significant for all measured properties except shoot height, shoot fresh weight and 1000-seed weight. In general, the results showed that application of NPK nano fertilizer had positive effect on the growth of tissue culture plants and resulted in improved yield.
