Effects of Types of Media and NPK Fertilizer on the Rooting Capacity of Chrysanthemum Cuttings

Abstract

Physiological status of chrysanthemum cuttings during rooting process highly influences plant growth and flower production. Amongst other aspects, rooting capacity of the cuttings is the most important. Rooting capacity is influenced by environmental conditions such as growing medium and nutrition. The study was aimed to analyze the effects of different types of media, fertilizer concentration, and frequency of fertilizer application on the rooting capacity of chrysanthemum cuttings. The experiment was conducted at the Segunung Experimental Station of the Indonesian Ornamental Crops Research Institute from February to May 2005. The treatments consisted of four different rooting media, i.e. carbonized rice husk, coco peat, perlite, and mixture of perlite and vermiculite (1:1 v/v); two concentrations of NPK (25:7:7) fertilizers, i.e. 1.75 and 2.5 g 1-l; and four frequencies of fertilizer application, i.e. every 1 day, 2 days, 3 days, and 4 days. The experiment was designed in a completely randomized block with four replications. Parameters observed were rooting capacity and cutting performances such as cutting height, cutting diameter, number of leaves, number of visible roots, and root length at 16 days after planting. The results showed that chrysanthemum cuttings rooted in carbonized rice husk had better performance than those rooted in coco peat, vermiculite, and mixture of perlite + vermiculite. Higher concentration of fertilizer solution up to 2.5 g l-1 also gave significant effect on the root formation and further root growth of cuttings. However, the rooting capacity of cuttings was not affected by the frequency of fertilizer application. This study implied that carbonized rice husk growing medium supplemented with NPK (2.5 g l-l) every 4 days during rooting period is the choice for traditional chrysanthemum growers to increase the perform-ance and quality of the cut flowers.

Impact of Growing Medium Composition on Morphological Development of Chrysanthemum (<i>Chrysanthemum morifolium</i> Ramat Cv. Snowball)

“…alters the physicochemical characteristics of the growing mixtures and affects plant growth, root system, nutritional status 2 as well as the value of potted ornamental plants 3 . There is evidence for growing chrysanthemum plants in soilless growing media, including perlite, peat, creamsite, rice husk ash 4 , soilrite 5 , treated coir dust 6 , carbonized rice husk 7 and cocopeat + soilrite, cocopeat + compost 8 . The plant height, spread, flower weight and number of flowers in chrysanthemum variety 'Punjab Anuradha' were observed to be maximum in cocopeat + sand + FYM + vermicompost in equal ratio 9 .…”

“…Similar effects were also observed in different other plants (Akter et. al., 2013;Islam et al, 2010;Jaheduzzaman et al, 2012;Khan et al, 2016).The increased amount of decomposed cow dung enriched Nitrogen (N) phosphorus (P), Potasium (K) in soil (Ewulo et al, 2007) which are responsible for root induction of Chrysanthemum (Budiarto and Sulyo, 2013).…”

Respon 10 Varietas Krisan (Dendranthema grandiflora Tzelev) terhadap Dua Aplikasi Pemupukan di Lahan Terbuka

“…Peningkatan produktivitas dan kualitas krisan dipengaruhi oleh berbagai faktor, seperti varietas, kualitas benih, pengelolaan tanah, waktu tanam, cara budidaya, pemupukan, penanganan pascapanen bunga hingga kondisi lingkungan tumbuh (Budiarto et. al., 2006;Kulkarni dan Reddy, 2010) dan infeksi Chrysanthemum virus B atau CVB (Budiarto et al, 2011).…”

“…Tanaman menjadi pendek disebabkan kurangnya batas kritis cahaya yang dibutuhkan dan pengaruh suhu yang tinggi. Budiarto et al (2006) tambahan, inisiasi bunga terjadi pada umur 30.9 hst; jika mendapat 4 jam cahaya tambahan inisiasi terjadi pada umur 64.8 hst. Waktu inisiasi cepat disebabkan karena tanaman tidak mendapatkan penyinaran tambahan.…”
