Abstract
Many organic and inorganic materials were used to enhance plant growth and soil fertility, in the present study phosphate and polyvinyl alcohol ( PVA) was used to prepare nanocapsules fertilizer by using Emulsification Solvent Diffusion Method (ESDM), nanocapsules of phosphate and polymer provide long-term sustained-release preparations, ensure long existence of fertilizer in attach with the plant. Particle size distribution was evaluated in addition to particle shapes were characterized by Transmission Electron Microscope (TEM), the activity of Nano-fertilizer was studied on Nigella sativa production and its extracts activity. The emulsification solvent diffusion method (ESDM) provided a good yield of P-nanofertilizer, nanoparticles size distribution ranged 40-150nm with particle size range 74.23nm
