Two field experiments were carried out during the two successive early autumn seasons of 2012/2013 and 2014/2015 to study the effect of the both amino acids as foliar application (0 and 2 g/l) and some stimulants ,i.e., microbial inoculants, humic acid, effective microorganisms (EM) and yeast strains (Saccharomyces cerevisiae, 110) as soil application on early and total fruit yield, its components and fruit quality. Spraying cucumber plants with amino acids increased significantly early yield and total yield in the first season only and average fruit weight in the second season only while TSS was significantly increased in both seasons. Also, microbial inoculants gave the highest number of fruits/m², average fruit weight; early and total yield /m² and TSS in both seasons except average fruit weight in the second season only comparing with the other stimulants. Microbial inoculants gave the lowest value of nitrate concentration of fruits comparing with the other stimulants.  The combination effect of stimulants and amino acids seems to increase early and total fruit yield and its components and fruit quality. In this connection using microbial inoculants or EM and amino acids gave the highest values of early and total fruit yield and its components and fruit quality.
