Effective management of nutrient application is important part the crop production puzzle and it seems that nano-fertilizers may have high potential for achieving sustainable production.A field experiment was carried out to investigate effect adding different nano-size biological fertilizers on maize growth under various irrigation regimes.The conducted optimal level (up ~50% capacity) which applied from beginning reproductive period.Fertilizer's treatments included control (Nf; no-fertilizer application), N biofertilizer (Bio-N), P (Bio-P), nanochelated B (Nano-B), nano-chelated Zn (Nano-Zn), complete nano-fertilizer (Nano-C) conventional mineral NPK fertilizer.Bio-P best treatment in terms grain yield, ear length, number kernels per row, length leaf straw yield traits, while Nano-Zn increase protein content Nf oil content.Bio-N area, diameter hundred weight, Nano-B plant height, harvest index, stem diameter, row ears traits.Nano-C are not outstanding any traits.Nano-Zn had good nano-B better performance ear, index traits.Such an outcome could be used future advise recommendation strategies recommendations other crops areas world.
