Effect of nano cobalt on some agro-biological characteristics of DT96 soybean cultivated in Vinh Phuc province

Abstract

Nanotechnology and nanomaterials were successfully applied in several countries to increase crop yield and quality. In Vietnam, some studies have focused on evaluating the effectiveness of using metal nanoparticles in many different plants. This study showed that the utilisation of nano-cobalt proved a good impact on the seed germination and agro-biological characteristics of the DT96 soybean cultivar (Glycine max L. Merr). Results exhibited that the treatment of DT96 soybean seeds with cobalt nanoparticle solutions increased the germination rate and remarkably increased the germination rate, in which the dose of 0.33 mg/kg of seeds gave good results (93.03%). In addition, nano cobalt also improved the
growth of DT96 soybean; stem height, root length, and dry weight of rhizomes... all increased more than the control and reached the maximum when being treated with a dose of 0.33 mg/kg of seeds.
