The Impact of Some Agricultural Economic Variables on the Value of Plant Production in Iraq: An Econometric Study Using the ADRL Autoregressive Distributed Time Lag Model for the Period (1990-2021)

Abstract

      The study aimed to identify the most important agricultural economic variables that have an impact on the trends in the value of plant production in Iraq during the period (1990-2021) using the ADRL model. The results showed the existence of a co-integration relationship between the study variables in the long term, and the variables (cultivated area, grain quantity, mechanical technology, chemical technology) are associated with a positive and statistically significant relationship with the value of plant production in Iraq in the long term, while the mechanical technology had an impact Negative significant on the value of plant production in Iraq during the study period. This may be due to the inability of farmers to use this technology (harvesters) in agricultural activities other than harvesting, or due to the agricultural lands not being suitable for using this type of modern agricultural mechanization, all of which led to the negative impact of this indicator on the value of plant production in Iraq.
