چکیده

این پژوهش به¬منظور بررسی اثر فواصل آبیاری و مالچ بر ویژگی‌های پومولوژیکی و عملکردی درختان 11 ساله زیتون رقم سویلانا در شرایط مزرعه در ایستگاه تحقیقات زیتون دالاهو واقع در استان کرمانشاه در سال زراعی1394‌ اجرا گردید. آزمایشی به صورت فاکتوریل در قالب طرح پایه بلوک‌های کامل تصادفی در سه تکرار اجرا شد. فاکتور اول آزمایش شامل فواصل آبیاری به صورت سه، شش (شاهد) و ده روزه بود و فاکتور دوم آزمایش شامل سه سطح مالچ پلی اتیلن، کاه و کلش و بدون مالچ (شاهد) بود. به¬منظور تعیین اثر فواصل آبیاری و مالچ بر زیتون رقم سویلانا در شرایط مزرعه برخی صفات پومولوژیکی و عملکردی از جمله وزن و ابعاد میوه و هسته، درصد رطوبت میوه، وزن تر و خشک گوشت، درصد ماده خشک، نسبت وزن خشک گوشت به هسته و عملکرد میوه در درخت و در هکتار ثبت گردید. سپس داده‌های آماری با استفاده از نرم افزارSAS مورد تجزیه و تحلیل قرار‌‌‌‌‌‌‌ گرفت و مقایسه میانگین‌ها به روش دانکن انجام شد. نتایج نشان داد که، بین تیمار‌های مختلف دور آبیاری و مالچ از نظر صفات اندازه‌گیری شده تفاوت معنی‌داری وجود داشت. به¬طوری¬که بیشترین میزان وزن میوه، وزن تر و خشک گوشت، عملکرد میوه در درخت و هکتار مربوط به تیمار مالچ و دور آبیاری سه روزه بود. با افزایش فواصل آبیاری وزن میوه، وزن تر و خشک گوشت، عملکرد میوه در درخت و هکتار کاهش یافت ولی با کاربرد مالچ وزن میوه، وزن تر و خشک گوشت و نیز عملکرد میوه در درخت و هکتار در مقایسه با شرایط بدون مالچ افزایش یافت. بر این اساس می‌توان با استفاده از مالچ‌های کاه و کلش و نیز پلی‌اتیلن دور آبیاری را بدون صدمه به درختان زیتون افزایش داد و از این طریق در مصرف آب آبیاری باغات زیتون صرفه‌جویی کرد.
