Abstract: This study was done in order to investigate the possibility and the most suitable formula of ensiling Cucurbit (Cucurbit pepo) residues. In a completely randomized design, Cucurbit residues were ensiled in 5 different formulas with 5 and after 2 month were assayed. Based on obtained results, following formula was accepted: %71.4 cucurbit residues + %28.6 wheat straw + %20 of DM beet molasses + %5 of Dm urea.
