ABSTRACT

The present study deals with the synthesis, characterization and influence of differential weight of copper nanoparticles on growth, biochemical characteristics and yield of black gram Vigna mungo. Copper sulphate was utilized for the synthesis of copper oxide nanoparticles using precipitation method and characterized by using UV- Vis Spectroscopy, SEM, EDAX, FTIR, and XRD. Differential weight of copper oxide nanoparticles (0, 100, 200, 300, 400, 500 mg) were utilized for growing black gram. After 60 days, growth, biochemical and yield parameters were measured. UV-visible absorption spectrum of the synthesized copper oxide nanoparticles was confirmed from the peak at 500 nm. SEM image of copper oxide nanoparticles was observed as spherical in shape. EDAX spectrum recorded on the copper oxide nanoparticles is shown as three peaks located between 2 KeV and 10 KeV. The functional groups of synthesized copper oxide nanoparticles were confirmed by FT-IR. The crystalline structure of synthesized copper oxide nanoparticle was obtained using XRD. Germination efficiency, Shoot length, root length fresh weight, dry weight, Vigor index chlorophyll a, b, total chlorophyll, carotenoid and L-proline of Black gram Vigna mungo was higher in T3 (300 mg). The protein content is higher in T1. The weight and number of Black gram was higher in T3.
