Effect of Nano Zinc Oxide Seed Treatment on Physiological Growth and Biophysical Traits and Seed Quality of Soybean [Glycine max (L.) Merrill]

The field experiment was conducted at Seed Technology Research Center, Department of Plant breeding and Genetics, JNKVV-Jabalpur Kharif-2021. Growth analytical attributes studies indicated superior performance seed treatment with nano-ZnO @500mg L-1 for LAI @60 DAS (days after sowing), @70 DAS, @80 LAD, CGR, RGR BMD w.r.t. 24.26%, 21.39%, 28.50%, 12.09%, 21.42%, 20.17% 20.56% enhancement over control. Varietal revealed variety JS 20-116 LAI, BMD. Biophysical parameters nano –ZnO chlorophyll content index energy interception 5.19% 26.51% control respectively. With respect to JS-20-116 interception. quality nano–ZnO final plant stand, germination, vigour I II 29.16%, 14.11%, 26.40% 21.43% variety, 20-34 germination. This results justifies that the formulation in form ZnO @ 500mg will improve growth attributes, physiological efficiency soybean. Hence is recommended farmers maximum productivity, sowing quality.
