Effect of Planting Date, Home Garden Direction, and Fertilizing with Compound Fertilizer (Hortifeeds) on the Number of Days Required for Flowering and on the Number of Flowers in the Middle of Each Month for Hybrid Carnation (Dianthus Chinensis X Barbatus)

Abstract

The study was carried out in the field of the Agricultural Research and Experiment Station belonging to the College of Agriculture / University of Kirkuk, located in the Al-Sayada area in Kirkuk Governorate, during the growing season from (9/15/2021) to (4/15/2022), to study the effect of planting dates. The first is (9/15/2021 and the second date is 9/30/2021), the direction of the home garden (south, east, and west) and fertilization with levels of compound fertilizer Hortifeeds that are (0, 1, 2, and 3) g.L−1 in growth and flowering Hybrid carnation plant (Dianthus chinensis x barbatus), The factorial experiment was carried out with a randomized complete design of three sectors, and the statistical analysis program (SAS) was used to analyse the data, and the Duncan polynomial test was adopted to compare averages at the 5% level.) The highest rates with a significant difference for the characteristics of the number of days required for flowering amounted to (136,860) days, the number of flowers for the month of January was (0.694) flower.plant−1, the number of flowers for the month of February was (7.238) flower.plant−1, and the number of flowers for the month of March was (41,632) flower Plant−1, while the number of flowers for the month of April did not reach the level of significant.
