The Lab experiments was conducted during kharif season of 2016-17 in laboratory of Department of Agronomy, Gandhi Krishi Vigyana Kendra (G.K.V.K), University of Agricultural Sciences (UAS), Bengaluru with different concentration of nano zinc oxide (800 ppm, 1000 ppm, 1200 ppm 1400 ppm and 1600 ppm) to assess the performance of maize seedling. Among the different concentration of nano zinc oxide 1200 ppm recorded higher root length (13.43 cm), shoot length (10.43 cm) and seed vigour index (2186.25) and lowest under De ionised distil water (6.53 cm, 5.79 and 1129.33 cm).
