Low efficiency of soil nutrition and reduction in the yield of peach trees in Khorasan Razavi province compared to the average yield of the country in recent years, identifying appropriate nutrition methods to improve the yield of peaches has been of great importance. In this context, the effect of foliar application of different levels of amino acid compounds, chitosan and their interactions on peach Alberta carried out factorially in the form of a randomized complete block design in 2019. The first factor, amino acid from the source of aminosoren at three levels of 0, 1 and 2 mg.l-1 and the second factor of chitosan from the source of cytoplas at three levels of 0, 2 and 4mg.l-1 were considered for foliar application. The results showed that foliar application of cytoplas levels increased the total chlorophyll content and firmness of fruit tissue Increased by 25 and 23% compared to the non-use of chitosan, which was statistically significant. It was also found that the combined application of aminosuren and cytoplas at the level of 2 and 4 mg.l-1 had the greatest effect on improving the total chlorophyll content (4.94 mg.kg-1 fresh weight), leaf area (40.61 cm2), tree yield (3.97 kg In tree), had average fruit weight (208.5 g), vitamin C (5.69 mg.100g-1 fresh weight) and firmness of fruit tissue (kg.cm2-1). In general, according to the results of this study, the combination of fertilizers containing amino acids and cytoplas can play a significant role in improving the quantitative and qualitative traits of peaches.
