​Role of Biofertilizer or Biopesticide in Agriculture Development and Novel Nano Bioformulation for Sustainable Agriculture

Background: The purpose of this research is to find out the awareness and the acceptance of the bio fertilizer in and around the Niligiri district. The survey has been conducted to identify the awareness among the farmer’s. Though, they are aware that, bio fertilizer will give more field than the chemical fertilizer farmers are unaware due to the low availability, high cost, initial low productivity. Since, bio fertilizers have significant and enduring environmental import, which nullifying the adverse effect of chemical fertilizer. The massive increase in the use of chemical fertilisers indicates that we are depleting our natural resources knowingly. This motivated the study to find out the awareness and acceptance of bio-fertilizers among the Tamil Nadu farmers and to find the ways and means of providing awareness to the farmers about the bio-fertilizers in order to increase their yield. The Niligiri district comprises of five taluk mainly Udhagamandalam, Kundah, coonoor, Kotagiri, Gudalur. The survey was carried out in and around of Kotagiri to Coonoor. The soil of Kotagiri and Kundah are more acidic in the nature. Organic carbon is high in all the type of soil. The available nitrogen content of the soil ranged between medium to high in all soil type. The phosphate availability is low due to the fixation of phosphate ion. The potassium content is high in all the type of soil. The ph plays major role in the soil type. The acidic soil might have lyst to open up and produce the juvnile. It is important to increase the soil fertility and better field non-organic fertilizer contains phosphate, ammonium etc. This could cause adverse effect in health as well as environmental problem.
Methods: It is an field investigation in 2020, the land are selected for the different resonance ranging from alluvial soil to the acidic soil. The study took place in and around the niligiri district, the fertilizers were  localized for the geographical condition the soils were assessed for the use of fertilizer and their need of resonance.
Conclusion: The use of the chemical fertilizers has damaged the soil resonance. The chemical fertilizer has caused serious life threatening problem in the human being. This measure can be solved by the usage of bio fertilizer on the soil. The lack of awareness among the farmers is the major crises that is developing. The measure can be solved by creating awareness among the farmers by cultural practice of use of bio fertilizer in their field.
