چکیده

برای بررسی تأثیر منابع و مقادیر نیتروژن بر عملکرد و اجزای عملکرد خیار آزمایشی به صورت کرت خردشده با طرح بلوک‌های کاملاً تصادفی با دو فاکتور در مرکز تحقیقات کشاورزی ایلام در سال 2006 انجام شد. اثرات نیتروژن خالص در سه سطح 0، 50 و 100 کیلوگرم در هکتار و همچنین تغذیه برگی در پنج سطح (محلول غذایی اوره در سه غلظت، محلول غذایی فوسامکو در یک غلظت و شاهد) بر روی کمیت و کیفیت خیار پائیزه رقم سوپر دامنیوس مطالعه گردید. نتایج نشان داد که کاربرد نیتروژن اثر معنا‌داری بر عملکرد، طول بوته، تعداد کل میوه و درصد ماده خشک میوه نداشت. اثر نیتروژن بر درصد ماده خشک میوه و بوته معنا‌دار شد. اثر تغذیه برگی بر صفات عملکرد کل میوه، تعداد کل میوه و طول بوته معنا‌دار و بر درصد ماده خشک میوه و بوته معنا‌دار نشد. اثر متقابل کود نیتروژن به صورت مصرف در خاک و تغذیه برگی بر صفات عملکرد کل میوه، تعداد کل میوه و طول بوته معنا‌دار و بر درصد ماده خشک میوه و بوته معنا‌دار نشد. با توجه به نتایج این تحقیق، تیمار 100 کیلوگرم در هکتار نیتروژن و محلول غذایی اوره 5/7 در هزار بالاترین عملکرد داشت و بهترین تیمار شناخته شد.

چکیده [English]

To investigate the effect of nitrogen sources and amounts on yield and yield components, cucumber was tested as a split plot with a completely randomized design of blocks with two factors in Ilam Agricultural Research Center in 2006. The effects of pure nitrogen at three levels of 0, 50 and 100 kg / ha as well as leaf feeding at five levels (urea nutrient solution in three concentrations, Fosamco nutrient solution in one concentration and control) on the quantity and quality of autumn cucumber of Super Damnius cultivar were studied. . The results showed that nitrogen application had no significant effect on yield, plant length, total fruit number and fruit dry matter percentage. The effect of nitrogen on fruit and plant dry matter percentage was significant. The effect of leaf nutrition on the yield of total fruit, total number of fruits and plant length was not significant and on the percentage of dry matter of fruit and plant was not significant. The interaction effect of nitrogen fertilizer in soil and leaf nutrition on the yield of total fruit, total number of fruits and plant length was not significant and on the percentage of dry matter of fruit and plant was not significant. According to the results of this study, the treatment of 100 kg / ha nitrogen and urea nutrient solution had the highest yield of 7.5 per thousand and was recognized as the best treatment.
