THE present study was undertaken during two successive seasons of 2011 and 2012 to study the effect of Ca(NO 3)2, K-silicate and CPPU at different concentrations either alone or in combinations on some fruit parameters, fruit characteristics and leaf nutrient content of peach tree cv. "Early sweeling" grown under El-Khatatba region condition, Minufiya governorate.The obtained results revealed that most treatments under study significantly increased both yield measurements kg/tree and (ton/fed.) as well as the other parameter (yield increment % in relation to the control) in the two seasons of study. Moreover, results indicated that, both the most of physical fruit characteristics (fruit weight, size, dimensions, and firmness) and chemical fruit characteristics such as (TSS %, total acidity % and total sugar %) were significantly improved as compared to the control. Additionally, leaf mineral content (N, P, K and Ca) was improved in some spraying treatments. It could be concluded that some of studied treatments resulted in a positive and significant effect on majority of investigated parameter and characteristics. Since, the treatment of Ca(NO 3)2 at rate (20 cm3/tree) after cytofex at 10 mg/l sprayed was the best and most effective treatment in this concern during both seasons of study.
