Abstract:
Recent years have witnessed an increasing acknowledgment of the remarkable impact that nanoscale particles have on plant growth. The unique properties exhibited by these particles offer exciting opportunities for enhancing various aspects of plant development. This study was aimed to investigate the effect of different concentrations of silicon dioxide (SiO2) nanoparticles (NPs) on content of micronutrient in rice a completely randomized design with three replications. This study explores the effects of foliar spraying, using different concentrations (50, 100, 200, 400, 600, 800, and 1000 ppm) of nanoscale silica (SiNPs) and silicic acid (4 ml/l), on the content of micronutrients such as zinc, copper, iron and manganese in straw and grain of rice at harvest. The highest recorded values for micronutrients content and uptake were observed in the T6 treatment (RDF + SiNPs @ 200 ppm) during the harvest stage, both in terms of straw and yield. The results of this study provide compelling evidence that the foliar application of particulate nanoscale silica plays a pivotal role in promoting increased growth and yield in rice.
