چکیده مقاله :
This study investigated the mechanisms of seed potato management by potato growers of Freydunshahr County in Isfahan province. Survey research method was used in this study. A sample of 250 potato growers (N=725) was selected for data collection. Stratified random sampling method was used. The research instrument was a questionnaire that was validated for face validity by a panel of faculty members and agricultural experts of Agriculture Jihad Organization in Freydunshahr County. For determining the reliability, Cronbach's alpha was estimated which turned to be higher than 0.7. Results showed that "a part of tubers produced by farmers" was the first priority of farmers as seed tuber source. Results showed that 89.6 percent of potato growers store and keep seed tubers in inappropriate conditions. Majority of the farmers did not have sufficient information on seed potato management and there was a positive and significant relationship between the farmers’ education and potato yield per hectare, but a negative relationship was found for age. Based on logistic regression analysis, the predictive power of the model was 0.639 and the sensitivity of total model to determine the correct percentage was 86.0 percent. Among individual, professional and economic factors, variables of age, number of family labor, area of owned land, area of potato farming, potato yield per hectare, number of owned land parcels and knowledge and information level of respondents significantly impacted on the adoption and use of modern seed potato production systems.
این پژوهش به بررسی سازوکارهای مدیریت بذر سیب زمینی توسط سیبزمینیکاران شهرستان فریدونشهر در استان اصفهان پرداخته است. این پژوهش به روش پیمایشی انجام شد. جامعه آماری تحقیق، شامل سیبزمینیکاران شهرستان فریدونشهر بودند. نمونهای متشکل از 250 نفر از سیبزمینیکاران (جامعه کل: 725 نفر) برای گردآوری اطلاعات تعیین شدند. روش نمونه گیری مورد استفاده در تحقیق، طبقه ای تصادفی با انتساب متناسب بود. ابزار تحقیق پرسشنامهای بود که روایی صوری آن توسط گروهی از اعضای هیأت علمی و کارشناسان جهادکشاورزی شهرستان فریدونشهر تأیید شد. برای تعیین پایایی تحقیق از آلفای کرونباخ استفاده شد که برای متغیرهای تحقیق بالاتر از 7/0 بدست آمد. نتایج نشان داد که "بخشی از غدههای تولید شده توسط کشاورزان" اولویت اول کشاورزان به عنوان منبع غده بذری سیبزمینی بود. 6/89 درصد از سیب زمینی کاران غدههای بذری را در شرایط نامناسبی نگهداری میکنند. دانش و مهارت اکثر کشاورزان درزمینه مدیریت بذر سیب زمینی پایین بود و رابطه مثبت و معنیداری با سطح تحصیلات و عملکرد سیبزمینی داشت ولی رابطه آن با سن منفی بود. براساس تحلیل رگرسیون لجستیک، قدرت پیشبینی مدل 639/0 بود و حساسیت کل مدل برای پیشبینی 0/86 درصد بدست آمد. همچنین از میان عاملهای فردی، حرفهای و اقتصادی، متغیرهای سن، تعداد نیروی کار خانواده، وسعت مالکیت زمینها، وسعت زیرکشت سیبزمینی، عملکرد تولید سیبزمینی در واحد هکتار، تعداد قطعات مالکیت زمینها و سطح دانش و اطلاعات در میان پاسخگویان بطور معنیداری بر پذیرش و بکارگیری سیستمهای نوین تولید بذر سیبزمینی دلالت دارند.
