Abstract
A laboratory study was undertaken to determine the response of sunflower to nano-sulfur application in comparison to conventional sulfatic fertilizer. Nano-sulfur particles were characterized using a particle size analyzer, zeta potential, UV-Spectroscopy, XRD, FT-IR, SEM, and TEM. After the complete characterization, the sulfur release pattern was studied in a percolation reactor system. Thereafter, response studies were carried out using sunflower (var. KBSH 42) crop. The stable and uniform nano-sulfur particles with a medium diameter of 35–45 nm are yielded by the aqueous precipitation method. The results showed that sulfur release from the nano-sulfur has prolonged for 42 days, while the sulfur release from the ordinary sulfur fertilizer (gypsum) ceased to exist within 35 days. Nano-sulfur fertilized plants had registered significantly higher dry matter production (11–12%), seed yield (15%), and oil content (14.7%) than gypsum fertilized plants. The data revealed that nano-sulfur assists in improving the available sulfur in soils.
