The present experimental investigation demonstrated the effect of TiO2 nanoparticle on germination and seedling growth parameters of mung bean. The experiment was carried out with six treatments using 0, 10, 20, 30, 40, 50 ppm of TiO2 nanoparticles including control with sterilized water under factor CRD manner following 3 replications. Application of TiO2 nanoparticle significantly stimulate germination and seedling growth with most of the treatment as compared with control. Lower concentration of nano TiO2 treatment in mung bean was found effective to enhance almost all the seedling characters like germination percentage, root length, shoot length, root fresh weight, shoot fresh weight, total fresh weight, root dry weight, shoot dry weight, total dry weight, root/shoot ratio, vigor index except root/shoot ratio of Sonali which showed no positive influence. Most effective treatment showing best performance considering all the varieties was found in lower concentration for all the seedling characters. Panna for germination percentage, IPM 23 for root length, shoot fresh weight, total fresh weight, shoot dry weight, total dry weight, vigor index and Sonali for shoot length, root fresh weight, root dry weight, root/shoot ratio were found most responsive with the treatment of TiO2 nanoparticle. The increase in seed germination along with seedling growth in specific concentration of TiO2 nanoparticle suggested optimum dose limit on growth of seedlings. Interaction of treatments with varieties was evident in most cases which could be considered as variable response on different varieties for which standardization of concentration of nanoparticle should be done to obtain most effective result.
