For this purpose, the researchers used the Toda-Yamamoto causality methodology for a time series covering from 1990 to 2019.

The research found a causal relationship between the agricultural terms of trade TOT and the agricultural labour LA towards agricultural product AP, and the existence of a significant causal relationship from all variables towards agricultural investment INV.

Therefore, the research recommends taking in consideration the results mentioned above and working to exploit the opportunities provided by the relationships among studied variables to avoid the reasons for problems such as the presence of terms of trade not in the interest of Iraq, as well as emphasizing the good opportunities, such as the crucial role of agricultural investment in raising the level of agricultural product and employment.
