This field investigate was conducted in 2021 and 2023 to evaluate the response of two potato cultivars to different levels of glycine in terms of plant dry mass (PDM), yield, total sold solutions (TSS), and some miniral elements analysis from aerial parts of potato plants. Two potato cultivars namely, Spunta and Larissa were exposed to three levels of glycine (0.0, 1.5 and 3.0 mM). Trial pieces were conducted as a factorial based on a randomized complete block design with three replications. glycine treatments led to significant effects on most characters, i.e., PDM and yield of two potato cultivars were significantly increased in all concentrations of glycine as compared to the control. As well, P content was increased by foliar application of glycine in all levels. but, K and Fe content in aerial parts were decreased. Also, a positive correlations were found among N and K, or/and K and Fe elements. Moreover, the results of this research revealed that increasing levels of glycine have positive effects on growth, biomass and yield of potato cultivars.
