The Effects of Compound Fertilizers Application to Different Commercial Tulip Varieties in Natural Growing Area on Plant and Bulb Growth

The study was conducted in Ibradı district of Antalya, the natural growth area of the plant, between 2020 and 2021, to determine the effects of compound fertilizer application on the growth, flowering and bulb development of tulip (Tulipa gesneriana L.) varieties. For this purpose, 5 different commercially popular tulip varieties (Queen of night, Apeldorn, Pink impression, Jaap groot, Royal virgin) and 2 different compound fertilizers (10-52-10+TE, 20-20-20+TE) were used and no fertilizer application was made in the control. Compound fertilizer (NPK 15-15-15) was added to the soil before planting. The experiment was established according to a two-factor (variety, fertilizer) randomized block design with 3 replications and 10 plants in each replicate. At the end of the study, the first sprouting occurred between 49 (earliest)-84 (latest) days after planting date depending on the varieties, the beginning of flowering was between the third week of March and mid-April, and the end of flowering was occurred at the beginning of May. The flowering longevity was between 14 and 21 days, plant length was measured between 29.6-42.8 cm. It was determined that there were significant differences among the varieties in terms of the sprouting time, beginning of flowering time, flowering longevity, increased plant height and bulb yield, but had no effect on the other characters.
