The effectiveness of synthesized ZnO nanoparticles on Zn uptake and some growth indices of wheat

Micronutrient deficiency like Zinc is one of the common problems in worldwide soils especially calcareous soils. Therefore, application of new methods including Zinc Oxide Nanoparticles is increasing to improve of nutritional status of this element in crops. Many studies showed that ZnO Nanoparticles application lead to increase of plant yield. Thus, present study was conducted to investigate of ZnO Nanoparticles effects on yield, concentration and uptake of Zn in root, shoot and grain of wheat under greenhouse cultivation in a calcareous soil.
This study was conducted in greenhouse condition as a randomized complete design with three replications. Treatment consisted of three levels of Zinc Nanoparticles (100, 200 and 300 mg.kg-1), ZnSO4 (40 kg.ha-1) and Control. During the experiment, some parameters such as plant height and chlorophyll index were measured. At the end of cultivation period, dry weight and Zn concentration of root, shoot and grain was determined using Atomic absorption. As well as,pH and soil available zinc was measured using DTPA extraction.
The amount of soil available Zn in all levels of ZnO Nanoparticles was significantly (P The results showed that application of ZnO Nanoparticles was increased yield, concentration and uptake of Zn in root and shoot of Wheat. Therefore, application of nanoparticles can be considered as one of the new methods for improving the yield and quality of crops and reducing the use of chemical fertilizers.
