Parthenium is one of the most common weeds grow throughout the world due to its remarkable adaptability to a wide range of environmental conditions and soil types. This weed plant shows both harmful and beneficial effects to agriculture, ecosystem and human health. Its uncontrolled growth not only negatively impacted on the cultivation of agricultural plants but also causes asthma, bronchitis, dermatitis and hay fever etc. to both animals and humans. It is believed that uncontrolled natural growth of Parthenium may have an overall negative impact on the ecosystem. The Parthenium compost without any of its contaminated seeds is the rich sources of agriculture plant's macro and micronutrients. Additionally various phytochemical constituents of parthenium have usefulness in agriculture as pesticides and therapeutic usefulness in the human society. The present compilation is an overview of the various aspects of parthenium growth both as natural contaminants during cultivation of agricultural plants as well as its controlled cultivation to benefit the agriculture, certain industries as well as overall human society.

Nanoparticles are a solid colloidal particle which ranges in size from 10 to 1000nm. The nanoparticles differs from its own bulk form in its physical properties and more over toxic than its bulk form. Due to these properties, nanoparticles can be used for a wide range of applications in various fields of science. Nanoparticles may be produced naturally, incidentally or can be engineered. These have profound multifaceted agricultural applications such as bioimaging, biosensors, nano-heribicides, nano-pesticides, nanofertilizers, etc. This study is focused on to review the properties, types, synthesis and multifaceted potential of different nanoparticles in agriculture fields for effective management, improved productivity and sustainable development.
