Abstract: Field experiments were conducted at the Agricultural College and Research Institute, Madurai, Tamil Nadu Agricultural University, Tamil Nadu, during kharif and rabi season of 2017 - 2018, to study the effect of nanoparticles in combination with herbicides and hydrogen peroxide on weed and crop plants. The experiments were laid out in randomized block design with twelve treatments and replicated thrice using blackgram MDU 1 as a test variety. The observation on growth parameters of plant height, leaf area index (LAI) and dry matter production (DMP) were taken at 20, 40 DAS and at harvest stage. The number of root nodules and their dry weight were taken at 30 and 60 DAS. Among the different treatments, weed free plot recorded higher dry matter production, number of nodules and dry weight of nodules, followed by application of H2O2 f pendimethalin @ 0.75 kg ai. ha-1 + ZnO nanoparticles (Nps) registered maximum plant height and leaf area index. However, it was at par with weed free plot. Next to the best treatments application of pendimethalin @ 0.75 kg ai. ha-1 + hand weeding at 35 DAS registered higher dry matter production, crop growth rate, number of root nodules and dry weight of nodules.
