Factors Affecting Fertilizer Consumption in Rajasthan

The present investigation was carried out to determine the factors affecting fertilizer consumption in Rajasthan from 1967-68 to 2014-15. The study period had been divided into following three phases; Post-green revolution- Phase I (1967-68 to 1980-81), Post-green revolution- Phase II (1981-82 to 1990-91) and Post-reform period (1991-92 to 2014-15).The regression analysis was done for the three temporal phases as well as for the overall period. High coefficient of multiple determination (R2) indicated that 90 per cent of total variation in fertilizer consumption was explained by the variables included in the linear regression model. Gross irrigated area was found to be the most important variable influencing the fertilizer consumption during the three phases as well as for overall period of study. Its coefficient was found positive and statistically significant (P<0.05). Area under high yielding varieties appeared to be the second most important variable significantly influencing the fertilizer consumption. Its coefficient was found positive and statistically significant (P
