Impact of Growing Media and Compound Fertilizer Rates on Growth and Flowering of Cocks Comb (Celosia argentea) Plants
The present study was conducted during consecutive seasons of 2016 and 2017 seasons in a private nursery belonging to Sakha Horticulture Research Station at Kafr El-Sheikh Governorate, Egypt. This study aimed mainly to investigate the effect of growing media including different mixture of peat moss and sand as 1:1, 2:1 and 1:2 v/v and NPK fertilizer at rates of 0 , 1.5, 3 and 4.5 g/pot and their interaction on growth, flowering and chemical composition of cocks comb (Celosia argentea) plants. The results revealed that growing media containing peat + sand (2:1) had significant positive effect on number of leaves and branches/plant, number of inflorescences and chlorophyll content (SPAD) as well as leaf chemical composition parameters (total carbohydrate, N, P and K %) in both seasons. Applying the complete fertilizer of NPK at 4.5g/pot was the best treatment for vegetative growth, flowering and chemical constituents of leaves. The maximum beneficial effect on the vegetative growth characteristics, number of inflorescences/plant and chlorophyll content (SPAD) and total carbohydrate as well as leaf, N, P and K % were obtained for plants grown in in peat + sand (2: 1 v/v) and fertilized by NPK (20: 20: 20) at rate of 4.5 g/pot. It can be recommended that to produce high inflorescences with a good quality of Celosia argentea plants for different purposes in the gardens by planting them in the mixture of peat moss + sand at 2: 1 v/v and fertilizing with complete fertilizer NPK (20:20:20) at rate 4.5g/pot four times stating after one month from transplant and then 2 weeks intervals.
