What are the free data sources in India where I can get input variables of farming (eg. Fertilizer, irrigation cost, labour, family size) and output variables (eg. Yield/total production).
Really interested in data source of Ag.input-output variables?Try various reports of Min.of agriculture(states & central),Planning commission,CSO,Dept. of Econ.&Stat.,Handbook of Statistics etc. surely u will get.
For farm level data one will have to collect only.
