Effect of phosphorus nanoparticle on germination and growth parameters of pulse crops mung, urd and cowpea were investigated in the present research work. Experiment was carried out in CRD manner with 3 replications. The six treatments using different concentration of P nanoparticle (10, 20, 30, 40, 50 ppm) includ-ing control with sterilized water were used in this study. All the five concentrations of nano phosphorus exerts positive impact on germina-tion and seedling growth in all the three crops over control. It was observed that with increase in P NPs concentration, germination and growth of seedlings also increases. However, after cer-tain concentration (40 ppm) they were found to decline. It was affirmed that the P NPs concen-tration of 20, 30 and 40 ppm showed statistically significant stimulation on germination and growth of the tested plants. The application of nano phosphorous in mung, urd and cowpea resulted as increases in germination percentage upto 20.83%, 38.1% and 20.83% respectively. Increases of upto 23.19% (urd), 47% (cowpea) and 76.78% (mung) in root length and 11.9% (urd), 33.66% (cowpea) and 62.32% (mung) in shoot length. Upswing in total fresh weight upto 79.87% in mung, 129.75% in urd and 190.88% in cowpea and in dry weight upto 107.69% (mung), 246.15% (urd) and 406.45% (cowpea) led to an enhancement up to 59.49% (urd), 69.04% (cowpea) and 103.99% (mung) in vigor index.
