چکیده

   این آزمایش به صورت کرت­‌های خرد شده در قالب طرح بلوک‌های کامل تصادفی در سه تکرار طی سال 1390 در پژوهشکده کشاورزی دانشگاه زابل اجرا گردید. در این آزمایش آبیاری در سه سطح، شاهد (50% تخلیه مجاز رطوبت)، تنش متوسط (70% تخلیه مجاز رطوبت) و تنش شدید (90% تخلیه مجاز رطوبت) به عنوان عامل اصلی و مقادیر کود سولفات پتاسیم در چهار سطح، عدم مصرف پتاسیم (شاهد)، 75 ، 150 و 225 کیلوگرم در هکتار به عنوان عامل فرعی بود. نتایج نشان داد تنش خشکی باعث کاهش وزن تازه، وزن خشک، ارتفاع، قابلیت هضم ماده خشک، پروتئین خام و افزایش هیدراتهای کربن محلول در آب علوفه گردید و در مقابل کود پتاسیم، وزن تازه، وزن خشک، ارتفاع، قابلیت هضم ماده خشک علوفه را افزایش داد، ولی هر دو تیمار بر تعداد ساقه فرعی بی تاثیر بود. بین سطوح کود پتاسیم بالاترین میزان عملکرد خشک و تازه علوفه، ارتفاع، تعداد ساقه فرعی، قابلیت هضم ماده خشک و هیدرات های­کربن محلول در آب در مصرف 225 کیلوگرم در هکتار کود پتاسیم بود. اثرات متقابل عوامل آزمایشی بر کلیه صفات مورد بررسی به جز تعداد ساقه فرعی معنی­دار بود. با توجه به نتایج به دست آمده جهت حصول حداکثر عملکرد کمی و کیفی علوفه بهتر است از تیمار آبیاری پس از 50% تخلیه رطوبتی و مصرف 225 کیلوگرم در هکتار کود پتاسیم استفاده گردد.
