Effect of planting date and bulb circumference width on bulblet yield of narcissus (Narcissus tazetta L.) flower

Abstract

In this study, the effects of planting date and bulb circumference on bulb yield were investigated in Narcissus tazetta flower. Narcissus spring bulbs, which were picked from nature in August, were divided into three groups (12.1-14, 10.1-12 and 8.1-10 cm) according to their circumference and planted in open field at different dates (September, October and November). In the research, bulb sprout rate, bulb circumference increase, and bublet formation rate were determined. As a result of the study, the best planting date (September) in terms of bulb circumference increase values (15.25 cm) and bulblet formation number (1.39 per plant) was revealed as a result of the study. The highest bulb circumference increase rate (34%) was obtained from bulbs with a circumference of 8-10 cm, while the lowest value (25%) was obtained from bulbs with a circumference of 12-14 cm. In terms of bulblet formation rates, there was no difference between circumference length. In the light of these data, it has been determined that bulbs with a circumference of 8-10 and 10-12 cm should be used to increase the bulb circumference. Bulbs with a circumference of 12-14 cm and larger should be used to obtain bulblet.
