به منظور ارزیابی کشت مخلوط ذرت شیرین و بامیه تحت تأثیر ورمیکمپوست و کود شیمیایی اوره، آزمایشی در مزرعه تحقیقاتی دانشگاه تربیت مدرس در بهار و تابستان 1394 انجام شد. در این تحقیق تأثیر پنج نسبت اختلاط ذرت شیرین: بامیه به روش جایگزینی شامل 100:0 (کشت خالص ذرت شیرین)، 75:25، 50:50، 25:75 و 0:100 (کشت خالص بامیه) و دو نوع سیستم تغذیهای شیمیایی (اوره) و ارگانیک (ورمیکمپوست) در آزمایشی به صورت فاکتوریل در قالب طرح بلوکهای کامل تصادفی با سه تکرار بررسی شد. نتایج نشان دادند که برهمکنش عوامل مورد مطالعه اثر معنی-داری بر تعداد بلال مرغوب و عملکرد بلال ذرت شیرین و عملکرد دانه بامیه در سطح احتمال یک درصد داشتند. همچنین عامل نسبت اختلاط بر وزن هزار دانه ذرت شیرین در سطح احتمال پنج درصد و بر وزن هزار دانه بامیه و تعداد میوه بامیه در هر متر مربع در سطح احتمال یک درصد تأثیر معنیداری داشت. بیشترین عملکرد بلال مرغوب ذرت شیرین و عملکرد دانه بامیه به ترتیب با تولید 58/9614 و 65/2848 کیلوگرم در هکتار از تیمار کشت خالص آن دو با دریافت کود شیمیایی اوره به دست آمد. بالاترین نسبت برابری زمین (10/2) از تیمار نسبت اختلاط 50:50 تحت سیستم تغذیهای ورمیکمپوست به دست آمد و مخلوط 75:25 (ذرت شیرین: بامیه) تحت همان سیستم تغذیهای با نسبت برابری زمین معادل 93/1 در رتبه بعدی قرار گرفت. ارزیابی شاخص رقابت در تیمارهای مختلف نیز رتبه بندی تیمارهای برتر را تأیید کرد. | ||

چکیده [English] | ||
In order to evaluate the intercropping of Sweet corn and Okra affected by vermicompost and urea fertilizer a field experiment was conducted at research field of Tarbiat Modares University during 2015 spring and summer. In this research effect of five mixing ratio of sweet corn/okra including: 100:0 (sweet corn monoculture), 75:25, 50:50, 25:75 and 0:100 (okra monoculture) and two nutrition systems consisted of chemical (urea) and organic (vermicompost) were investigated with factorial arrangement of treatments based on randomized complete block design with three replications. The results showed that factors interaction on the number of desirable ear, sweet corn yield and okra seed yield were significant (P≤ 0.01). Also mixing ratio effect on sweet corn 100 kernel weight (P≤ 0.05), okra 1000 kernel weight and the number of fruits square meter (P≤ 0.01) was significant. According to mean comparisons the highest sweet corn yields (9614.58 kg.ha-1) and okra (2848.65 kg.ha-1) was obtained in their monoculture receiving the chemical fertilizer. The highest LER (2.10) was obtained in 50:50 treatment under vermicompost nutrition system followed by 75:25 under same nutrition system (LER=1.93). Also competition index evaluation in the different treatment confirmed the rating of superior treatments. | ||
