چکیده مقاله :

به منظور بررسی اثر متانول و روی بر شاخص های رشد و عملکرد بادام زمینی رقم NC2از آزمایش فاکتوریل با طرح پایه بلوک های کامل تصادفی در 3 تکرار در سال زراعی 90-89 در شهرستان بندر کیاشهر واقع در استان گیلان استفاده گردید. مقادیر مختلف مصرف متانول (صفر، 10، 20، 30 درصد حجمی) و کلات روی (صفر، 5/0، 1، 5/1 گرم در لیتر)، تیمارهای مورد بررسی را تشکیل دادند. نتایج حاصل نشان داد مقدار مصرف متانول و روی بر شاخص سطح برگ، وزن خشک غلاف، سرعت رشد گیاه، سرعت رشد غلاف، عملکرد غلاف، عملکرد دانه، بادام زمینی تاثیر معنی دار داشت و بیشترین مقدار آنها مربوط به تیمارهای 20 و 30 % حجمی متانول و 5/1 در هزار روی بود. اما مقدار روغن دانه ها بین شاهد و بوته های تیمار شده با متانول تفاوت معنی داری نداشت. همچنین اثر متقابل محلول پاشی متانول و روی در صفات اندازه گیری شده به جز مقدار روغن دانه معنی دار بود. حداکثر عملکرد غلاف و عملکرد دانه (6809 و 5181 کیلوگرم در هکتار) با مصرف 30% حجمی متانول به همراه 5/1 در هزار روی به دست آمد. بالاترین شاخص سطح برگ، سرعت رشد گیاه و سرعت رشد غلاف به ترتیب در 90 و 105 روز پس از کاشت با همان مقدار مصرف متانول و روی نیز به دست آمد.

چکیده انگلیسی:

     NC2 variety of a Factorial experiment with randomized complete block design in 3 replication during 2010-2011 done in Bandar Kiashahr county located in Guilan province is used to survey effect of methanol and zinc on peanut growth index and yield. Various methanol application (0, 10, 20, 30 v/v) and zinc chelate (0, 0.5, 1, 1.5) in 1000 cc formed surveying treatments. The result showed that methanol application had significant impact on leaf area index, pod dry weight, crop growth rate, pod growth rate, pod yield, grain yield, and maximum belonged to 20 % and 30 % v/v of methanol and 1.5/1000 cc zinc application treatments. But amount of seed`s oil had no significant difference between witness and plants treated with methanol. Also interaction effect of methanol and zinc was significant in all parameters except oil content. Maximum seed and pod yield (6809 and 5181 kg/h) were gained by 30 % v/v of methanol and 1.5/1000 cc zinc application. The highest leaf area index, growth rate of plant and pod growth rate were gained respectively in 90 and 105 days after planting with same methanol and zinc application mentioned above.
