Abstract
Selection of an optimum fertilizer is mandatory step for proper growth and development of a crop. Many chemical and organic fertilizers have negative impacts on environmental, and human health. Slow releasing fertilizers are recently used fertilizers, urea coated hydroxyapatite nanoparticles are one of them. These release Nitrogen slowly into the soil, and have no side effects on humans and environment. In the present investigation, these nanoparticles were synthesized, and characterized by using X-ray diffraction, FESEM, and FTIR techniques. Then, their effects at different concentrations (250 ppm, 500 ppm, 750 ppm, 1000 ppm) were observed at seed germination attributes of two varieties of Brassica juncea L. i.e. GIRIRAJ, and NRC-BH 101. Those were also compared with control plants and plants grown in treatments with the same concentrations of urea. Results revealed that synthesized nanoparticles were 23-32 nm in size, and for all the parameters, seed germination was the maximum at treatment with 500 ppm of urea coated hydroxyapatite nanoparticles when compared to others while higher concentration of these nanoparticles (1000 ppm) lower seed germination attributes. All the results were significantly compared.
