Effect of Various Types of Growing Media and Application of Liquid Organic Fertilizer on the Growth of Dendrobium Orchids

Abstract

This research was a potted experiment carried out in a special orchid house (arnet) at the Padang Galleria Padangsambian Kelod from September to November 2019, the aim was to determine the effect of plant media and the provision of liquid organic fertilizers on the growth of dendrobium orchids. The factorial CRD pattern was the design used in this study, which consists of two factors, first, the use of growing media of wood charcoal (K), fern stems (P), and a mixture of fern stems with wood charcoal (M) and, second, the provision of liquid organic fertilizer, namely, Dewa (D), DI Grow (I), and GDM (G). The results showed that the interaction between the use of planting media and the application of liquid organic fertilizer had no significant effect on all plant growth parameters such as plant height, number of leaves, and number of tillers. However, the plant medium as a single treatment had a significant effect on the number of orchid tillers, fern stems (P) as the plant medium gave the highest number of tillers, namely: 2.22 stems or 32.93% more than the growing media for wood charcoal (K) and a mixture of charcoal, wood and fern stems (M) with 1.67 tillers each

The Effect of Dosage and Frequency of Leri Water Spraying on Phalaenopsis Fuller's Pink Stripe Orchid Growth of Aclimatisation

“…The epidermis is also rich in vitamins, minerals, and phytochemicals. (22) believes that the advantage of organic fertilizers is to prevent pesticides and other pesticide residues from polluting the environment. Organic fertilizers can improve soil structure, increase fertility, maintain and increase nutrient utilization and increase nutrient availability.…”

“…The number of microorganisms. According to (22), when plants are unable to give the necessary nutrients, their metabolism becomes problematic, affecting plant growth and development. As a result, even when organic materials are employed, additional nutrients are still required (through fertilization).…”

“…Indriani et al, (2019) menjelaskan bahwa pupuk daun "farmer" konsnetrasi 1 ml/L dan 2ml/L yang diaplikasikan pada tahap aklimatisasi hanya berpengaruh terhadap jumlah daun anggrek Phalaenopsis. Arthagama et al, (2021) melaporkan bahwa pemberian pupuk organik cair kemasan "Dewa" (mengandung mineral, asam amino dan zpt), "DIGROW" (pupuk organik dari rumput laut Ascophylum Nodosum) dan GDM (pupuk organik hayati campuran bakteri + limbah organik + rumput laut + alga + minyak hewani) secara signifikan tidak pengaruh terhadap pertumbuhan anggrek Dendrobium.…”
