Abstract: Mustard (Brassica nigra L.) is an important oil crop of India. There has been an expansion of acreage as a result of “Second Green Revolution†brought by the high yielding varieties of the oilseed. Applications of nanotechnology are novel in the field of biotechnology and agriculture. Metal-oxide nanoparticles (NPs) have unique physicochemical properties and possess the potential to boost the plant metabolism. Increasing demand of mustard provokes the research to estimate the feasibility of effective dose NPs for increasing yield potential along with quality production of mustard. Seeds of two mustard varieties namely Shyam 101 and Super teja were soaked for 24 hrs with NPs of iron-oxide, copper-oxide, and zinc-oxide (100, 200, 300, 400, and 500ppm). These soaked seeds were sown in pots and were kept in net house. The results revealed that lower doses of NPs stimulated seed germination in both the varieties whereas higher concentrations of copper-oxide NPs and zinc-oxide NPs strongly inhibited the germination. All the metal-oxide NPs enhanced plant height at 400ppm (at 20 days after sowing) and number of branches at 400ppm (at 40 days after sowing), in both the varieties. The maximum number of silique per plant and the maximum silique length were exhibited by copper-oxide NPs at 400ppm. Higher concentrations of iron-oxide NPs (400ppm) and copper-oxide NPs (300ppm) displayed superior responses for test weight (g) and harvest index (%) respectively.
