چکیده مقاله :

This research investigated the effectiveness of IPM/FFS project from economic, technical, social-communicative, environmental and psychological aspects in a descriptive-correlational design based on the survey method. The research population consisted of 70 greenhouse producers that had implemented IPM/FFS project in Tehran and Alborz provinces, Iran. Using Krejcie and Morgan (1970)'s sample size table and stratified random sampling method, 55 greenhouse producers were selected as the research sample. A questionnaire was the main tool for data collection. The validity of the questionnaire was confirmed by a panel of agricultural extension and education experts and its reliability was confirmed by calculating Cronbach's alpha coefficients (0.77≤a≤0.86). The results showed that the IPM/FFS project has affected social-communicative, psychological, environmental, technical and economic factors, respectively. There were positive and significant relationships between effectiveness of the IPM/FFS project and education, the duration of IPM implementation, satisfaction with governmental support and the characteristics of IPM/FFS learning sites whilst the effectiveness of IPM/FFS project was negatively and significantly related to age and greenhouse area under IPM project. According to multiple regression analysis, the characteristics of IPM/FFS learning sites, education and satisfaction with governmental supports could account for 66 percent of variance of the effectiveness of IPM/FFS project. Finally, as implementation cost of integrated pest management is usually beyond greenhouse producers’ financial ability, it is suggested that the government provide greenhouse producers with more economic supports (e.g. granting loan and special facilities and guaranteed purchase of organic products).

چکیده انگلیسی:

این پژوهش به بررسی اثربخشی پروژه­ی IPM/FFS، از ابعاد اقتصادی، فنی، اجتماعی- ارتباطی، زیست­محیطی و روانشناختی پرداخته است. تحقیق از نوع توصیفی ـ همبستگی می­باشد که با روش پیمایشی انجام شده است. جامعه تحقیق شامل 70 نفر از گلخانه­داران استان­های تهران و البرز بوده است که پروژه IPM/FFS را اجرا کرده­اند. با استفاده از جدول کرجسی و مورگان (1970) و نمونه‌گیری طبقه‌ای تصادفی 55 نفر از گلخانه­داران مذکور به عنوان نمونه تحقیق انتخاب شدند. پرسشنامه ابزار اصلی جمع‌آوری داده‌ها بود که روایی آن به تأیید پانلی از متخصصین ترویج و آموزش کشاورزی رسید و پایایی بخش­های مختلف آن در مرحله پیش‌آزمون با محاسبه آلفای کرونباخ بین 77/. و 86/. محاسبه گردید. با توجه به نتایج، پروژه IPM/FFS به­ترتیب روی ابعاد اجتماعی- ارتباطی، روانشناختی، زیست­محیطی، فنی واقتصادی گلخانه‌داران تأثیر می­گذارد. اثربخشی پروژه IPM/FFSبا متغیرهای تحصیلات، مدت زمان اجرای IPM، میزان رضایت از حمایت­های دولتی و ویژگی­های سایت­های یادگیری IPM/FFS، دارای رابطه مثبت و معنادار و با متغیرهای سن و مساحت اجرای IPM، دارای رابطه منفی و معنادار بود. طبق نتایج تحلیل رگرسیون چندگانه، سه متغیر ویژگی­های سایت­های یادگیری، تحصیلات و میزان رضایت از حمایت­های دولتی قادرند 66 درصد از واریانس متغیر اثربخشی پروژه  IPM/FFSرا تبیین کنند. در نهایت پیشنهاد می­شود از آنجا که هزینه اجرای مدیریت تلفیقی آفات، معمولاً بیش از توان مالی گلخانه­داران است، حمایت­های اقتصادی دولت (نظیر اعطای وام و تسهیلات ویژه، تضمین خرید محصولات ارگانیک) از گلخانه­داران مجری افزایش یابد.
