The Effect of Cocopeat and Rice Husk Planting Media Hydroponically on the Growth of Palm Oil in Pre Nursery

Abstract

Palm oil can produce high productivity which must be supported from several aspects, one of them is a good and correct nursery. Palm oil nursery isusually carried out conventionally, namely planting using soil media. Hydroponic research using cocopeat and rice husks planting media on the growth of palm oil seeds in pre nursery has never been carried out. The objective of this study was to determine the growth of palm oil seedlings using the hydroponic method. This research was conducted in the STIPAP Medan greenhouse. This research was conducted from April to July 2018. This research was a non-factorial RAK, which consisted of four treatments, namely M0 (top soil), M1 (Cocopeat), M2 (rice husks), M3 (combination). Height, stem, number of leaves, dry and wet weight of roots and plants, root length were observed. Then data analysis with ANOVA with the continued test of 5% Duncan was performed. The results of the effect of cocopeat and rice husk media was there was no a significant effect on the treatment parameters of seed height, number of leaves, dry and wet weight of roots and plants, and root length.

Utilising crop residues as hydroponic media for sustainable food production system

“…Peat moss has an acidic pH and an organic composition, however because of its low nutrient concentration, it might not be the best choice for hydroponics. In hydroponic systems, the selection of substrate should generally be based on a balance of nutrient availability, pH compatibility, and sustainability [7,11,12] .…”

“…On the other hand, the medium containing rice husks showed better root length and dry weight, but no appreciable changes in overall parameters. However, the best medium for height characteristics turned out to be a combination of cocopeat and rice husk [12] . Additionally, studies into sawdust and bag culture hydroponic systems produced better cut flower outcomes and sawdust was shown to be the best growing medium for gypsophila cultures.…”

Interaction of Co2 and Light Availability on Photophysiology of Tropical Coccolitophorids (Emiliania Huxleyi, Gephyrocapsa Oceanica, and Ochosphaera Sp.)

“…indicates that the carbon dioxide (CO2) generated by calcification is less than that required for photosynthesis, and an external source of CO2 is required, while a calcification to photosynthesis ratio of >1 implies that the CO2 generated from calcification is greater than the cellular requirement for photosynthesis, and excess CO2 is produced (Beardall & Raven, 2013;Coad et al, 2016;Rickaby et al, 2016;Singh et al, 2016;Djaingsastro et al, 2021).…”

Cocopeat Perlite Mixture as an Alternative for Rooted Cuttings Growth Medium of Impatiens hawkeri x platypetala in Indonesia

“…This medium showed the capacity to effectively anchor the root system, thereby facilitating the absorption of water and nutrients, resulting in the formation of longer roots due to the activity of the lateral meristem (Li et al, 2018). The increase in root width caused by the lateral spread influenced the dry weight (Djaingsastro et al, 2021). The application of Notes: numbers followed by the same letter in the same column show no significant difference based on the DMRT with an α = 0.05.…”
