Abstract
The study aims at estimating and analyzing some of the factors affecting the growth of agricultural production in selected developing countries for the period 1970–2000. A sample of the developing countries have been selected and divided into two groups, the first of which is the countries with higher medium income, including: Turkey, Thailand, Tunisia, Syria and Yemen. The second group is the countries with low medium income, including: Morocco, Egypt, Jordan, Pakistan and Bangladesh. An econometrical model was used with three models: linear, semi logarithmic, and double logarithmic where concepts of the economic theory and previous studies concerning estimating and analyzing the factors affecting the agricultural growth obtained from time series data for each country are used as they reflect the factors affecting the agricultural growth of each country as related to their characteristics differing from the other country.
