The research was carried out in the experimental fields of Bayindir Vocational Training School at Ege University between the 2017-2018 vegetation periods. Five different commercial tulip varieties (Canadian Liberator, Van Eijk, Pink Impression, Carousel, Holland Beauty) were used as plant material. The research was carried out with three replications of randomized block design with two factors (cultivars, bio fertilizer application). In this study, first sprouting time, the beginning of flowering time, end of flowering time, flowering longevity, plant height, stem length and bulb yield values were examined. According to the data obtained from the research; the first sprouting occurred 49-72 days after planting date, the beginning of the flowering was in the range of the first week to the last week of March, and the end of flowering took place in the last week of March and mid-April. The flowering longevity was between 13 and 20 days, plant length was measured between 33.8 - 44.6 cm. Following to this stem length was measured and the value recorded between 27.3 - 36.2 cm. It was determined that the application of bio fertilizer increased bulb yield and did not reveal any impact on the other characteristics which was emphasized in this study.
