Nanoparticles (NPs) have different applications because of their special physical and chemical properties. The chemical method of nanoparticle synthesis is difficult due to its toxicity while the green route is considered ecofriendly. Different studies and experiment’s data give the information about the properties exerted by the nanoparticles. All plants / seeds uptake their nutrients from nature but in some severe conditions we provide them with extra nutrients from outside to prevent their loss during seed germination process.The paper consists various data about the requirement of nanoparticles, their applications, the hazardous effects of the nanoparticles, various methods of preparation of nanoparticles via their synthesis, the advantages and the disadvantages of the nanoparticles based on their synthesis, the effects of various nanoparticles on the seed germination and it includes the analyzed data of effect of nanoparticles like zinc, copper, titanium, silver and iron synthes

Nanoparticles are those particles which can enhance the properties of plants, seed growth or seed germination. Nanoparticles synthesised through green nanoparticles are less costly. While on the other hand, chemical methods such as sol-gel technique, polymer precursor method, etc, are expensive, which is the first reason why, green synthesised nanoparticles are more preferable over chemically synthesised nanoparticles. Chemically synthesised nanoparticles may be effective or helpful in seed germination but according to our study of different articles shows that, they can be toxic for the seed growth. Green synthesised nanoparticles are better way to enhance the seed germination without or with less toxic effects; they are eco-friendly, cost effective and they possess antimicrobial properties with amazing effects. As mentioned above chemically synthesised nanoparticle’s effects are also depends upon the types of soil as well as on the type of crops. Different studies proved that green
