Nanotechnological approaches to study the effect of silver nanoparticles on yield, quality and shelf life of onion

Abstract

An experiment was conducted to understand the effects silver nanoparticles (AgNPs), on yield, quality and shelf life of onion, varieties Arka Pragati. AgNPs of less then100 nm size in five different concentrations, viz. 0, 25, 50, 75 and 100 ppm were used as a treatment. Result indicates that impact of AgNPs in different parameters was concentration dependent. Higher concentration of AgNPs gives batter result then low concentration. Maximum yield was recorded in 100 ppm (38.10 t/ha) compare to control (33.33t/ha). Maximum equatorial diameter, polar diameter, ten bulb weight, number of ring was observed in T1 (100ppm) but no significant difference was observed among all the treatment for TSS and bulb dry weight. A noticeable result was also recorded in shelf life also. Rotting percentage (%) and Black mould incident was reduced considerable in T4 however no significant difference was observed in PLW and TSS during storage.
