Foxtail Millet Responses to Bulk and Nano Zinc Oxcide Particles in Water Stress Conditions.

Aims : This study was done to investigate the effects of zinc oxide (ZnO) nanoparticles application on foxtail millet in water stress conditions. Place and Duration of Study: The experiment was conducted at the Agricultural Research Center of Islamic Azad University, Birjand branch, Iran in 2011. Methodology: Experimental design was split plot based on randomized complete blocks with three replications. Two irrigation treatments (control and water stress) and seven ZnO fertilizer (control without ZnO, three levels of bulk ZnO (3000, 6000 and 12000 ppm) and three levels of ZnO nanoparticles (250, 500 and 1000 ppm) were as main plots and sub plots, respectively. Result: The results showed that water stress declined peduncle length, stomatal conductivity, germination percentage and grain yield. Seed protein content increased under water stress imbalance in the soil may also have contributed to the prevention of any positive effects of zinc consumption on plant growth parameters.
