Kajian Perkembangan Akar Tanaman Kelapa Hibrida (Cocos nucifera) pada Lahan Gambut dengan Tinggi Muka Air Berbeda

Peatlands in Indonesia have great potential for agriculture, but their management requires special attention due to the water-saturated and acidic characteristics of the soil. One commodity that can be cultivated on peatlands is hybrid coconut (Cocos nucifera), which plays an important role in the Indonesian economy. However, coconut productivity is often hampered by non-optimal management, especially water table management. This study aims to analyze the effect of different water levels on the root development of hybrid coconut plants in peatlands. This study aims to determine the optimal depth of water table to support the maximum development of hybrid coconut roots.
The research was conducted using a survey method in Coconut Plantations in Desa/Kepenghuluan-Teluk Nilap, Kubu Babussalam District, Rokan Hilir, Riau Province, for three months from March to May 2024. The location was determined by purposive sampling method, and sampling wasdone by stratified sampling based on three different water table levels, namely 20 cm, 40 cm, and 60 cm. For each water level, five plants were sampled so that a total of 15 samples were analyzed. Parameters observed in this study include root length, root weight, root number, root volume, and root density. Observations were made by measuring the length of primary and secondary roots, weighing the fresh and dry weight of roots, counting the number of primary and secondary roots, measuring root volume using a measuring cup, and root density calculated based on root weight at each soil depth.
The results showed that the 40 cm water table gave the best effect on root development of hybrid coconut plants, which was seen in the parameters of root length, root weight, root number, root volume, and root density. In detail, the length of primary and secondary roots, fresh and dry weight of roots, number of primary and secondary roots, and root volume of coconut plants at a water table of 40 cm showed higher results compared to plants at a water table of 20 cm and 60 cm. At a water table of 20 cm, coconut plants showed shorter root length and lighter root weight, while at a water table of 60 cm, coconut plants experienced a decrease in water availability, which resulted in a reduction in root volume and density. It can be concluded that water table management in peatlands should be maintained at a depth of 40 cm to support optimal root development, which in turn will increase the growth and production of hybrid coconut plants.

Keywords: Fresh and dry root weight, root density, hybrid coconut, peatland.
