Резюме: През периода 2020-2022 г. в опитното поле на ИПЖЗ-Троян са проучени следните бобови фуражни треви: звездан (Lotus corniculatus L.), хибридна детелина (Trifolium hibridum L.), люцерна (Medicago sativa L.), червена детелина (Trifolium prаtense L.) и бяла детелина (Trifolium repens L.). Целта на експеримента е въз основа на осреднени данни за морфологични особености, добив и качество на фуража да се направи статистически анализ и се определят зависимости между тях. Установена е силна корелационна взаимовръзка между: височината на растенията и съдържанието на сурови влакнини (r = 0.88); съдържанието на сурови влакнини и относителния дял на бобовите в тревостоя (r = 0.77); съдържанието на киселинно-детергентни влакнини и това на целулоза (r = 0.92). Тези резултати дават възможност за извеждане на регресионни зависимости, представени чрез линейни уравнения и коефициенти на детерминация.
Ключови думи: корелационен анализ; бобови фуражни треви; регресионни зависимости; двуфакторен дисперсионен анализ
