Nano-Zn Suspension Production Technology

Description and Salient Features :

The nano-zinc suspension is prepared by a novel chemical process with polymeric capping agent to make it a stable suspension. The average size of nano-Zinc particle is 82.0 ± 10 nm as analysed by DLS nanoparticle size analyser. The zeta potential is +25mV as analysed by DLS electrophoretic technique. Using this nano-zinc suspension, an increase in grain yield of 30% was reported in chick pea grown in sandy soil, by ICAR-IIPR, Kanpur. Also, the zinc fertilizer requirement could be reduced to the level of 75% in dryland paddy and fodder maize as reported by ICAR-NIASM, Baramati. The pot culture study and field trials were conducted during the years 2021-2023.
