Response of Dianthus caryophyllus L. Plants to foliar nutrition [electronic resource].

Includes reference.

This investigation was inducted at Nubaria Region, West of Alexandria City, Egypt, during 2006 and 2007 seasons to study the influence of different concentrations (0.0,0.2,0.4,0.6,0.8, and 1.0 %) of foliar fertilizer contains macro -elements (20%N, 20% P, 20% K, 0.12% Mg) and micro -elements (70 ppm Fe, 14 ppm Zn, 16 ppm Cu, 42 ppm Mn, 72ppm B and 24 ppm Mo) on the growth, flowering, and chemical analysis of leaves of Dianthus caryophyllus cv. "Red Sim". The foliar fertilizer was applied 5 times during the growing period. The results revealed that plant treated with foliar nutrition showed significant increase in the growth characteristics (stem length , stem diameter, stem fresh and dry weight, number of leaves/ plant, fresh and dry weight of leaves). As well as, stimulated the flowering parameters ( reducing tbe number of days from planting to flowering, increased both number, size, fresh and dry weight of flowers/plant) compared to the untreated plants (control). The treatment of 0.6 % of foliar fertilizer gave the highest values compared to the other treatment in both seasons. The total chlorophyll (a+b) , carotenoides and total carbohydrates (%),the mineral. contents of leaves( N,P,K, Zn and Cu) were significantly increased as a result of spraying the plants with foliar fertilizer at different rates compared to the control treatments.
