Abstract
The experiment was conducted at private nursery in Babylon governorate during the growing season of 2006-2007. The objective of the study was to investgate the effect of potassium sulphate fertilizer (51% K2O) at dosages of 8 kg /ha-1 and super phosphate fertilizer (46% P2O5) at dosage of 20 kg.ha-1, applied either alone or forgather on vegetative growth, flowers characteristics, and seeds yield. The experimental design used in this experiment was a Randomized Complete Block Design (R.C.B.D.) with three replicates. Duncan Multiple Range Test (DMRT) at probability level of 0.05 was weed to compare the means of treatments. Results revealed that K and P had significant effect on improving vegetative growth such as plant height, (cm) stem diameter (cm), number of leaves per plant, number of branches per plant, average number of branches roots per plant, number of flowers per plants and number of petals per flower. Significant results were also obtained in increasing the weight of 100 seed to 2.5gm and total seed yield to 1.768 ton.ha-1 of plants treated with potassium fertilizer compared with control treatment which produced 1.69gm and 0.413 ton.ha-1 for both traits, respectively. Results also indicated that phosphate fertilizer improved characteristics of vegetative and flowering growth, and seed yield of calendula plants.
