Planting Season and Nutrition Effects on Carnation Production: Comparison of Planting Seasons and Macro Nutritional Levels on Growth, Yield and Vase Life of Dianthus Caryophyllus

This research was conducted to elucidate the effect of various planting seasons and macro nutritional NPK levels on growth, yield and vase life of carnation. The experiment was envisaged in Floriculture Research area, Institute of Horticultural Sciences, University of Agriculture, Faisalabad. The results indicated that the overall best performance of carnation production such as plant height, number of branches per plant, length of branches, number of leaves per plant, leaf area, NPK contents, flower diameter, flower quality and vase life was due to T2 (5:10:10 g pot-1 NPK). Whereas, planting season S1 (16th Nov.) showed better results for indices like plant height, number of branches per plant, length of branches, number of leaves per plant, NPK contents, flower diameter, fresh weight of flower, fresh and dry weight ratio and flower quality as compared to planting season S2 (15th February).
