ABSTRACT This experiment was laid out in order to determine the effect of nano-Zinc chelate and nano-biofertilizer on yield and yield components of maize under water stress condition on a loam clay soil, in Islamic Azad University of Boroujerd, Iran, during the growing seasons 2013- 2014. The experiment was laid out in a split-factorial design based on randomized block design with three replications. The experiment was laid out in a split-factorial design based on randomized block design with three replications. Treatments were different irrigation periods (7, 14 and 21 days) in main plots and nano-Zinc chelate and nano-biofertilizer in two levels of use and non use of them as factorial in sub plots.
