الملخص EN

This study aims at identifying the determinants of wheat production in Algeria during the period of 1990-2019, and the contribution of the combined effects of each determinant on the production amount achieved from wheat.

a relationship between the produced amount of wheat and the other variables-affecting it-such as: the cultivated area, the manpower, the machinery, and the amount of rain; depending on the general form of the production function "Cobb-Douglas".

the study relied on descriptive and experimental approaches using the multiple linear regression test.

the study concluded that wheat production witnessed big fluctuations due to climatic change conditions and the applied agricultural policies, where significant impacts of machinery and cultivated area on the amount of wheat production had been depicted.

furthermore, the results showed that wheat production followed the law of increasing yields, as the model was instable at the time-point of the year 2000, which witnessed the executing of the national plan for agricultural and rural development.
