About: This is the website of National Horticultural Research & Development Foundation (NHRDF) and maintains a database on Market Arrivals and Price, Area and Production and Export Data for three commodities - Garlic, Onion and Potatoes. It also has data from 1996 onwards and has only got one form to fill to get the data in a tabular form.
Uses the Data Wise Market Arrivals and Price Data
Data.gov.in - This is normally a good place to get government data in a machine readable form like csv or xml. The Variety-wise Daily Market Prices Data of Onion is available for each year as an XML/JSON but unfortunately it does not include quantity information that is needed. It would be good to have both price and quantity - so even though this is easy, lets see if we can get both from a different source. Here is the best link to go to get what is available - https://data.gov.in/catalog/variety-wise-daily-market-prices-data-onion#web_catalog_tabs_block_10
Agmarket - This is the website run by the Directorate of Marketing & Inspection (DMI), Ministry of Agriculture, Government of India and provides daily price and arrival data for all agricultural commodities at national and state level. Unfortunately, the link to get Market-wise Daily Report for Specific Commodity (Onion for us) leads to a multipage aspx entry form to get data for each date. So it is like to require an involved scraper to get the data.
