| Abstract : A Study on the effect of chelated Mg and Ferric sultate (FeSo4) on growth and flowering of Callistephus chinensis plants was carried out . Four concentrations of Mg (0 , 2 , 4 , 8 g/l) and four corcentrations of FeSo4 (0 , 1.5 , 3.0 , 4.5 mg/l) were foliar applied three times . The first application was done after a month from the transplanting , While the second one was applied 21 days later , the third applications was sprayed after 21 days from the second application . The results could be summarized follows magnesium treatments significantly increased most of the studied characters . The highest level (8 g/l) was more effective on plant height (27.87 cm) ; number of leaves (35.78) ; leat area (21.47 cm2) ; number of branches / plant (19.98) ; fresh weight (29.94 g) ; number of flowers / plant (21.96) ; flower diameter (6.66 cm) ; flower stem diameter (5.08 mm) ; flower stem length (21.2 cm) ; flowers fresh weight (7.67 g.) and dry weight (0.88 g.) . The concentration of FeSO4 (4.5 mg/l) was the effective on most parameters tested . Height of plaets became (32.74 cm) ; No. of branches (21.73) ; leaf area (19.29 cm2) ; Chlorophyll% (17.58%) ; fresh weight of the vegetative growth (28.83g) ; No. of flowers/plant (22.51) ; flower diameter (6.23 cm.) ; flower stem diameter (3.88 mm.) ; flower stem length (20.15 cm.) ; vaselife (10.42 days) and flower's fresh weight (6.80g) . Most of interaction treatments were improved signifcaatly parameters tested. | ||
