Iron deficiency is a widespread nutritional problem in plants growing mainly in high pH and calcareous soils. Application of iron compounds with the technology of Nano may be a solution to the problem. Iron nanoparticles may have potential to improve growth and yield of wheat crop. It is the first time in Bangladesh to determine the potentiality of iron nanoparticles for enhancing seed priming, germination, growth and yield of wheat. Three experiments like synthesize of iron nanoparticles, seed priming or seedling growth and field experiments were conducted for this purpose. An aqueous method has been considered to prepare iron nanoparticles in water by reducing their ionic salts such as FeCl3 in presence of surfactant (PVP) under oil bath heating for several minutes. The synthesized nanoparticles were purified by precipitation method. The size of synthesized iron nanoparticles were 10.2±7.7 nm. Wheat seeds were soaked in 0.0, 1.0, 1.5, 2.0 and 2.5 ppm solutions of iron nanoparticles to quantify seed priming effect. A sand culture seedlings growth experiment was conducted to quantify nanomaterials deliver to wheat seedlings. The treatments of the experiment were determined, including nanoparticles of iron at two levels like before germination and seven days of germination; doses of priming at five concentration levels of nanoparticles were 0.0, 1.0, 1.5, 2.0 and 2.5 ppm. The BARI Gom 25 was used for seed priming and seedling growth experiment. Whereas, the BARI Gom 28 was used for growth and yield in the field. Seed germination and seedlings growth was regularly affected with 1.0 to 2.0 ppm but decreased significantly at 2.5 ppm of iron nanoparticles. The growth and yield of the BARI Gom 28 significantly enhanced with 2.0 ppm iron nanoparticles as compared without nanoparticle under field experiment condition. This study concluded that optimum level of iron nanoparticles concentration helps to increase growth and yield of wheat plant. Further experimentation is required to explore the internal mechanism of iron nanoparticle absorption and mode of application for yield maximization of wheat.
