چکیده مقاله :
به منظور بررسي تاثير محلول¬پاشي عناصر روي و آهن بر عملكرد و اجزاي عملكرد سويا آزمايشي به صورت فاكتوريل در قالب طرح بلوك¬هاي كامل تصادفي در چهار تكرار در سال 1388 در مزرعه تحقيقاتي دانشگاه آزاد اسلامي واحد كرج انجام شد. تيمارهاي محلول¬پاشي شامل سه سطح محلول¬پاشي آهن (عدم محلول¬پاشي، يك بار محلول¬پاشي، دو بار محلول¬پاشي) و سه سطح محلول¬پاشي روي (عدم محلول¬پاشي، يك بار محلول¬پاشي، دو بار محلول-پاشي) بودند. نتايج نشان داد كه محلول¬پاشي آهن تاثير معني داري بر عملكرد سويا نداشت و اختلاف معني¬داري را با عدم محلول¬پاشي نشان نداد. اثرات متقابل محلول¬پاشي آهن و روي بر روي صفات مورد بررسي معني¬دار نبود. نتايج نشان داد كه دو بار محلول¬پاشي روي تاثير معني¬داري بر عملكرد و اجزاي عملكرد سويا داشت و عملكرد دانه را به ميزان 1276 كيلوگرم در هكتار نسبت به تيمار شاهد افزايش داد. هم¬چنين يك بار محلول¬پاشي روي نيز اختلاف معني-داري را نشان داد و به ميزان 607 كيلوگرم در هكتار عملكرد سويا را نسبت به تيمار عدم محلول¬پاشي افزايش داد. نتايج هم¬چنين نشان داد كه دو بار محلول¬پاشي روي باعث افزايش معني¬دار مقدار ماده خشك گياه گرديد، كه اين افزايش در تيمار دو بار محلول¬پاشي 95 درصد بيشتر از تيمار عدم محلول¬پاشي بود. نتايج ازمايش نشان دادكه مي¬توان با محلول-پاشي روي، عملكرد سويا را تا حد زيادي افزايش داد.
To study the effect of zinc and iron foliar application on yield and yield components of soybean an experiment was carried out in factorial based on complete randomized design (CRD) with four replications in the research fields of Islamic Azad University- Karaj branch in 2009. Foliar treatment was included three levels Iron (non foliar, once foliar, twice foliar) and three levels Zinc (non foliar, once foliar, twice foliar). Results indicated that iron foliar did not have significant difference on soybean yield. Interaction between iron and zinc showed that the total of traits were not of significant difference. Results indicated that effect of twice foliar zinc had significant differences on yield and yield components and seed yield increased as compared with control (example or non foliar) about 1276 kilogram in hectare. also zinc once of foliar indicated significant differences of soybean yield increased as compared with control (example or non foliar) about 607 kilogram in hectare. Also results indicated zinc to twice foliar caused significant increase of seed dry matter that this increase in zinc twice foliar treatment was 95 percent more than none foliar treatment. This experiment results indicated that zinc foliar could increase the soybean yield.
