Long Run Analysis:
The long-run causality between the factors and their influence on food-grain production in this paper is assessed by the help of VECM model. As a precondition to that the lag selection test suggests two lags following the majoritarian principle as Akaike Information Criteria (AIC) and Hannan -Quinon (HQ) criteria both suggest the same. In order to check the possible long run association we use Johansen Cointegration test. As a pretesting for Johansen all the variables are required to be integrated of order one i.e. I(1) nature. Below is the results of Unit Root test analysis of all the variables following Augmented Dicky fuller (ADF) test and Phillips-Peron (PP) test of stationarity.
