The Study of the Causes of Reduction in the Poplar Plantation Level in the Markazi (Central) Province (A Case Study in Arak-Khondab Region)

In order to study the causes of reduction in the poplar plantation level in the central province, a region in the west part of this province, located in Khondab district, a part of Arak, alongside the Garachi river, beginning from the Doab bridge and the Mahdiabad village and continuing to Khandab, was investigated. The statistical samples of this study include 5114 poplar planting families from which 900 were selected based on Koukran formula, and they filled out the questionnaires. The relative simple randomization method was used to select the sample subjects. After collecting and classifying the data, the principles of descriptive statistics were used. The results of the study showed that the low level of villager's education and the use of old and traditional methods (little and late productivity), and their unfamiliarity with new and improved species and methods of poplar blending plantation were the main reasons for the reduction of poplar plantation level and the change to fruit gardens, especially the peach gardens (due to its early productivity and suitable market).
