ABSTRACT
This study was conducted to determine the effect of nanoparticles (magnesium nitrate, ferrous chloride and zinc nitrate) on seed (corn and tomato) germination. Phytosynthesis was employed using moringa leaves as plant extract to synthesis to the salts (ferrous chloride (FeCl2), magnesium Mg(NO3)2), and zinc nitrate (Zn(NO3)2). Spectrophotometer was used for the characterization of the salt reading for absorbance wavelength, from 300 to 500nm for 3 days. The result showed that the peak of the absorbance was recorded at 400nm for all the nanoparticles. It indicates the effect of ferrous chloride nanoparticles on the germination of plumule length measurement was recorded at highest on day 7 at 100% increase and radical length measurement was recorded highest on day 9 for the treatment. The highest growth observed was at day 5 for control and treatment. Treatment had positive impact on the radical length of corn seed for Magnesium nitrate nanoparticles. The effect of zinc nitrate nanoparticles on the germination were on radical and plumule length of corn seed which indicates the major growth seen from 72hours at 80% germination rate. It can be concluded that the germination of yield increases in days for corn seed but tomato seed lack germination rate especially in magnesium nitrate and zinc nitrate nanoparticles, this is due to the determination of the duration and quantity of salt present in the precursor solution resulting to a negative result.
