What is the difference between Bharatiya Prakritik Krishi Paddhati and organic farming under PKVY?

They are related but not the same, and the difference matters for inputs and certification. Bharatiya Prakritik Krishi Paddhati (BPKP) was the natural farming sub scheme, now carried forward under the National Mission on Natural Farming, and it promotes chemical free farming based on cow based and locally made inputs like jeevamrit and beejamrit, with very low external input cost, and it works through clusters, training and bio input resource centres. Organic farming under PKVY allows a wider range of permitted organic inputs including bought organic manures and biofertilisers, and it puts strong emphasis on PGS group certification so you can sell as certified organic. In short, natural farming is the cow based, near zero external input approach focused on cost reduction and soil health, while PKVY organic is the certified organic route focused on standards and the certified market. Which to choose depends on your goal, if you want lowest cost and self reliance go natural farming under NMNF, if you want a certified organic label for distant or premium buyers go the PKVY organic and PGS route. You can also combine the practice of natural farming with PGS certification. Confirm the current structure of both with your agriculture department, as the schemes have been reorganised.
