Impact of Nanoscale Zinc Oxide Particle on the Growth, Yield and Soil Properties under Agency Area of Andhra Pradesh

Field experiment was carried out on silt clay loam soils at Regional Agricultural Research station, Chintapalle, Visakhapatnam, Andhra Pradesh during 2018-2020 to study the yield of response rainfed groundnut with different levels Nano particulate zinc oxide application along NPK Fertilizers. The consisting eight treatments, three replications RDF design. Results nano pod showed that (24.36 Q/ha) in RDF+ scale level @ 200 ppm 25 and 45 DAS increased over normal recommended dose N,P,K fertilizers (100% RDF) which recorded 17.14 Q/ha only.
