Abstract Two field experiments were conducted at Sakha Agricultural Research Station, kafr El-Sheikh Governorate, Cotton Research Institute, Agricultural Research Center at Giza, Egypt during the two summer growing seasons, 2014 and 2015. The aim of the work was to study the effect of the combination among nano-fertilization, mineral fertilization and organic fertilization on growth, yield, yield attributes and fiber technological properties of Egyptian cotton Giza 94 cultivar. The most important results can be summarized as follows: Response of cotton yield and lint properties to mineral N.P.K., nano-fertilization treatment contains half dose of both the nano-fertilizer and the organic fertilizer gave the highest values of plant height (cm) , number of fruiting branches per plant, boll weight (g), number of opened bolls per plant ,seed cotton yield (kentar/fed) ,lint cotton yield (kentar/fed), lint percentage , seed index (g) , upper half mean (UHM) mm, fiber uniformity index (UI), fiber strength (g/tex), fiber elongation (%), micronire reading, maturity ratio (MR), fiber fineness (millitex), short fiber content (SFC), yellowness degree (+b) and reflection degree (Rd%). On the other hand, the lowest values for all the above traits, were recorded from the half does of NPK mineral fertilizer in 2014 and 2015 seasons, respectively. It’s worthy to mention that, there was no significant differences between the means of the fiber elongation % due to the treatments applied during the study in 2014 season, while, it had no constant trend due to fertilizer transactions applied on the adopted genotype during 2015 season. Adding to that, both of short fiber content and yellowness followed opposite trend as compared to all previous characters under study.
