| Abstract | ||
| A pots experiment conducted in the experimental field of Horticulture Department, Collage of Agriculture and Forestry, Mosul University, between September 2007 to June 2008 on carnation cultivars Jeanne Dionis Blano (white flowers) and Marie Chabaud Jaune (yellow flower), to investtigated the effect of potassium fertilization by using potassium sulfate K2SO4 at (zero and 1.5 and 3.0) gm. pot-1, interaction with spraying three concentrations of boron (zero, 20 and 40)mg. L-1 on second flowers yield, by using Split Plot within Randomized Complete Block Design. With three replicated and three pots for experiment unit. The results showed that superiority of the Marie Chabaud Jaune on Jeanne Dionis Blano in number of flowers and the length of steam flower gave the 6.34 flower. Plant-1 and 40.6 cm length steam flower, potassium fertilization 3 gm.pot-1 gave highest flower diameter at 4.13 cm, the treatment of spraying boron 40 mg.L-1 caused significant increase in the number of flowers to cultivar Jeanne Dionis Blano. Treatment Interaction between the Marie Chabaud Jaune and potassium fertilization 3 gm. pot-1 and without spraying boron gave highest flower diameter 4.43 cm. | ||
