The aim of this research was to investigate the effect of processing industries on reducing agricultural products’ wastes. A causal- comparative research method was used for this purpose. According to experts’ opinions, two villages (with & without processing industries) were selected. Sample size was determined as 330 ones using Krejcie and Morgan table and stratified sampling with proportional allocation. A research-made questionnaire was used to collect datawhich itsvalidity was confirmed by experts’ view and its reliability measured by calculating Cronbach’s alpha coefficient. The result of the research showed that agricultural products’ wastes in village with processing industries are less than it in village without processing industries. Other results showed that post-harvest wastes have reduced two percent because of processing industries. Furthermore, storing and preserving wastes have reduced 6. 67 percent due to processing industries. Moreover, agricultural food processing wastes have diminished 11. 67 percent. Finally, these industries cut down 23 percent of transiting and distributing agricultural wastes. According to the results of this study, the most effect of processing industries on reducing agricultural products’ wastes was in transiting and distributing stage and the least effect was in post-harvest stage.

The aim of this research was to assess socio-economic impacts of Henna culture in rural regions of Mohammad-Abad Township of Ghalehganj County. Thus, a causal- comparative research method was used in this study. To select research sample, at first 20 villages were selected as the main Henna growing areas. Then, Numerical Taxonomy technique was used to select homogenous regions between them. In this study, farmers were divided into three groups i.e. Henna growers, non-Henna growers in villages with Henna growing and non-Henna growers in villages without Henna growing. Research population included 1241 farmers that about 298 ones of them were selected as research sample using Kerjecie and Morgan random sampling table and stratified random sampling technique. Also, a researcher designed questionnaire was used to collect data which its validity was verified using face validity procedure and its reliability was either verified calculating Cronbach's Alpha reliability coefficient (from 0.63 to 0.93). The comparison of current situation of socio economic criteria between the supposed groups showed that Henna growers have a better socio- economic status. To ensure that if this difference is the result of Henna growing, Covariance analysis was used. Final results also verified that Henna growing have had statistically significant and positive effects on socio- economic status of the respondents.
