چکیده

زمینه و هدف: استفاده از ورمی کمپوست از جایگاه ویژه‌ای در کشاورزی برخوردار است. این امکان وجود دارد که گیاهان زراعی نسبت به کود تهیه شده در مراحل اولیه رشد حساس باشند، لذا مطالعه‌ حاضر با بررسی تأثیر جوانه­ زنی و وضعیت فیزیولوژیکی گیاه ترتیزک با استفاده از ترکیب ورمی کمپوست‌های مختلف انجام شد.
مواد و روش‌ها: در این مطالعه به بررسی اثر جوانه­ زنی گیاه ترتیزک (شاهی) با استفاده از عصاره ورمی کمپوست با درصد حجمی 0، 15، 30 و 45 درصد حجمی از ورمی کمپوست تهیه شده از فضولات گاو، زباله میوه، کاغذ، خاک اره و برگ توسط کرم خاکی Eiseniafoetida پرداخته شد. تجزیه و تحلیل داده‌ها با استفاده از نرم‌افزار آماری SPSS (نسخه 11/5) و آزمون واریانس یک طرفه(One-way ANOVA) و دوطرفه(Two-way ANOVA) انجام گرفت. میزانp  کمتر از 0/05 معنی‌دار در نظر گرفته شد.
یافته‌ها: بر اساس نتایج مطالعه حاضر، درصدهای حجمی متفاوت در رشد گیاه ترتیزک مؤثر بودند. میانگین رشد در درصد حجمی 30 نسبت به درصد حجمی 15 و 45 اختلاف معناداری داشت و کمتر از آن‌ها بود. سطح 15 درصد حجمی تهیه شده از کود ورمی کمپوست تولیدی، جهت رشد گیاه و جوانه­ زنی سطح مناسبی می‌باشد.
نتیجه‌گیری: کود ورمی کمپوست ترکیبی تهیه شده   با درصد حجمی  15 درصد می‌تواند نقش مؤثری در افزایش کارایی تولید گیاه ترتیزک داشته باشد.

چکیده [English]

Background &Objeftive:
Vermicompost application plays an important role in agriculture. Crop plants can be sensitive to negative effects of vermicompost at early stages of development. The aim of the present study was to test the effects of different vermicomposts on seed germination of lepidiumsativum species.
Materials & Methods:
In the current work, the effects of different vermicomposts’ extracts, which were produced from cow manure, fruit waste, paper, sawdust and leaves, on s germination and early development of lepidiumsativum were investigated in various volumetric percentages (0%, 15%, 30% and 45%). For data analysis, Statistical Package for Social Science (SPSS) program and ANOVA test were used.
Results:
The results showed that different volumetric percentages were effective on lepidiumsativum growth. Average growth in volumetric percentage of 30% was less than  15 and 45%. In the way that presence differences was significant. Volumetric percentage of 15%  was in appropriate level for plant growth and seed germination.
Conclusion:
It can be concluded that the use of vermicompost extracts can have an effective role in production efficiency increase of lepidiumsativum.
