| Abstract | ||||
| Lucrative approaching of nanotechnology and its application on plant is gradually growing recently. Based on this fact an investigation was done during two successive seasons 2018 and 2019 to scrutinize the consequence of nano macro elements application represented in NPK individually or in combination and nano zeolite with and without loaded nitrogen on a sage plant grown under drought stress in comparison with commercial NPK fertilizers at a newly reclaimed area of the desert. The outcome results revealed that nano-zeolite loaded nitrogen, as well as nano-NPK mixture, donated outstanding results with reference to vegetative growth (plant height, number of branches, herb fresh and dry weights, leaf area, yield fresh weight, health index, and oil yield) beside photosynthetic rate, stomatal conductance, intercellular CO2 concentration, water use efficiency, relative water content, and chemical composition symbolized in (plant pigments, total carbohydrates, total phenols, tannins, total flavonoids, oil constituents, macro, and micro-elements) alongside indigenous hormones characterized in (gibberellic acid GA3 and abscisic acid ABA), antioxidant enzymes (peroxidase and superoxide dismutase) in contrast to the commercial dose of chemical fertilizers NPK (as control) under the same conditions. Moreover, leaf anatomical structure supported the acquired vegetative growth parameters and chemical analyses results. The outcomes of the current study gave emphasis to global warning about pollution resulted from chemical fertilizers particularly in newly reclaimed areas and safety production of medicinal and aromatic plants. | ||||
