چکیده

    به منظور بررسی اثر متقابل کشت مخلوط خیار و بامیه، آزمایشی به مدت یکسال زراعی(1387) در شهرستان نوشهر، به‎صورت فاکتوریل در قالب طرح پایه بلوک‎های کامل تصادفی در چهار تکرار اجرا شد. تیمارهای الگوی کشت در چهار سطح: کشت خالص خیار یا بامیه، کشت بامیه داخل ردیف خیار، کشت بامیه بین ردیف‎های خیار و  الگوی کشت بامیه بین و داخل ردیف‎های خیار و تیمارهای تراکم در سه سطح (فاصله کشت بین بوته 20‌، 30 و 40 سانتی‎متر) بودند.صفات رویشی و عملکرد، غلظت عناصر پتاسیم، فسفر، کلسیم و نیتروژن در تیمارهای آزمایشی مورد مقایسه قرار گرفتند. نتایج آزمایش نشان داد که  در بوته‎های خیار،کشت مخلوط باعث افزایش غلظت عناصر کلسیم (19%)، پتاسیم (12%)،  عملکرد (12%) و  کاهش غلظت نیتروژن (12%)،  تعداد شاخه فرعی (23%) و سطح برگ (15%) شد. برای بامیه، کشت مخلوط باعث افزایش غلظت عناصر فسفر (3%)، نیتروژن (16%)، سطح برگ بوته (41%)، وزن‎تر بوته (26%) و کاهش غلظت کلسیم (8%)  نسبت به کشت خالص شد.اثر متقابل الگوی کشت و تراکم بر روی عملکرد و اجزای عملکرد خیار معنی‌دار بود،  ولی تنها بر روی اجزای عملکرد بامیه اثر معنی‌داری داشت. نسبت برابری زمین در همه تیمار‌های کشت مخلوط، بزرگ‎تر از یک بوده و بالاترین نسبت برابری  زمین (15/2) در تیمار کشت مخلوط بامیه بین بوته و ردیف‎های خیار، با تراکم متوسط به‎دست آمد. نتایج این تحقیق نشان ‎داد که  بین دو گیاه خیار و بامیه نوعی سازگاری و هماهنگی وجود دارد که  می‎تواند حاصل ویژگی‎های فیزیولوژیکی وگیاه‎شناسی و عوامل مساعد اکولوژیکی باشد که باعث افزایش عملکرد در دو گیاه شده است.

چکیده [English]

In order to study the interaction effect of cucumber and okra in intercropping culture, an experiment was carried out in Nowshar in 2008. This experiment was done as a factorial experiment based on a randomized complete block design with four replications. Treatments were  planting patterns (sole cropping of okra or cucumber, okra was intercropped within cucumber rows, okra was intercropped between cucumber rows and okra was intercropped within and between cucumber rows), and planting distances (20, 30 and 40 cm inter-row spaces). In this experiment, yield and yield component, calcium, potassium, nitrogen and phosphor content and vegetative characteristics were measured. Results showed that in the cucumber plant, intercropping increased calcium content by 19%, potassium content by 12%, yield hectare-1 by 12%, and it reduced nitrogen content by 12%, number of branches per plant by 23% and leaf area by 15% compared to sol cropped cucumber. In okra plant, intercropping increased phosphor content by 3%, nitrogen content by16%, leaf area by41%, fresh weight of plant by 26% and it reduced calcium content by 8% compared to sol cropped okra.The interaction effects between planting patterns and planting density were significant for yield and yield components of cucumber but, it was significant only for yield of okra plant. The land equivalent ratios were all above 1.00, and the highest LER of 2.15 were obtained when okra was planted between and within cucumber rows at medium planting densities. The results of this experiment showed a kind of compatibility and conformity between cucumber and okra plants, may be due to their, physiological and botanical characteristics and favorite ecological factors that could cause an increased cucumber and okra plants yield.
