Abstract EN

Factor analysis is one of the most important statistical methods through which it is possible to measure economic development and productive power in various geographical regions.

In this study, factor analysis was used to measure the developments of plant production in the agricultural sector in the Aseer region, Saudi Arabia.

The study concluded the following : - The factor analysis showed the presence of three main factors that together explained about %86.55 of the total variation in the development of plant production in the governorates of the Aseer region.

- The study showed three mathematical algorithms that can measure the development of plant production in the Asir region according to the three main factors : First factor equation λ1=44.250%=-0.521*X_1 0.810*X_2+0.78*X_3+0.842*X_4+0.755*X5 Second factor equation λ2=24.960%-0.228*X_1+0.352*X_2+0.936*X_3-0.226*X_4- 0.380*X5 The third factor equation λ3=17.344%=0.796*X_1+0.291*X_2+0.104*X_3+0.339*X_4- 0.153*X5 -The study classified the governorates of the Asir region, based on the results of the analysis, into three groups, according to negative and positive 0.933 − 0.975 and includes Bisha - Abha - Ahad Rafaida - Khamis Mushait - in Al-Furn - Al-Barak, while the second group represents the category of 0.897 − 0.548 and includes the governorates of Mahayel, Asir - Tanmomah - Al-Namas - Tathleeth.

The third group includes the category of 0.255 − −0234 and includes the governorates Sarat Ubaidah - Al-Majadra and Bariq - Tareeb - Dhahran Al-Janoub and Al-Harajah - Rijal Almaa
