چکیده

به منظور بررسی اثرات تاریخ، عمق و فاصله کاشت بر رشد و محصول دهی زعفران در شرایط آب و هوایی شهرستان ماکو، آزمایشی به صورت فاکتوریل در قالب طرح پایه بلوک­های کامل تصادفی با سه تکرار در مزرعه تحقیقاتی دانشگاه آزاد اسلامی واحد ماکو در دو سال زراعی 1388و 1389 اجرا گردید. فاکتورهای آزمایش شامل تاریخ کاشت در دو سطح 25 شهریور و 7 مهر ماه، عمق کاشت در دو سطح 20 و 25 سانتی متر و فاصله کاشت در دو سطح 20 و 25 سانتی‎متر بودند. نتایج نشان داد که تعداد برگ، وزن تر و خشک برگ، وزن تر و خشک گل، وزن تر و خشک کلاله، طول کلاله و سطح برگ گیاه تحت تأثیر سطوح مختلف تاریخ، عمق و فاصله کاشت قرار گرفت، به طوری که شاخص­های رشد و عملکرد گیاه مانند وزن تر و خشک گل و وزن تر و خشک کلاله در تاریخ کاشت اول (25 شهریور ماه) افزایش یافت. هم‎چنین عمق کاشت و فاصله کاشت بر صفات مورد نظر تأثیر داشته و بیشترین میزان عملکرد در فاصله کاشت کمتر و عمق کاشت کمتر به دست آمد.
