“…The estimated biomass carbon stock of Asystasia intrusa was very low compared to that of oil palm fronds, M. malabatricum, and Cycas sp. Biomass carbon stock recorded in the smallholder plantations in peatland in Aceh was 9.4-12.2 ton/ha/year (Maswar, 2009;Maswar et al, 2011). While the biomass carbon stock in tropical Asian forests was 40-250 ton/ha (Lasco, 2002).…”

Abstract. Satriawan H, Fuady Z, Ernawita. 2020. The potential of Asystasia intrusa weed as a cover crop in oil palm plantations. Biodiversitas 21: 5711-5718. Weeds generally found in oil palm plantations, one of which is dominant is Asystasia intrusa. This weed has begun to be used as a cover crop on oil palm land because it is assumed to have a beneficial effect. The purpose of this research is to explore the potential of Asystasia intrusa in growing as a cover crop on oil palm plantations. The experimental arrangement used was split-plot design. Oil palm plan’s ages were used as the main plot, while the spacing plant (Asystasia intrusa) as the subplots. Experiments were done in triplicate. The results showed that Asystasia intrusa has the potential to be used as a cover crop in oil palm plantations, since it meets several requirements, such as quickly covering the land (12 WAP), fast decomposing (30-60 days), tolerance to shade. This was indicated by the growth percentage of 97.56%, containing nutrients N (1.65-1.77%), P (0.29%), and K (4.6-4.97%), as biomass (0.9 t C/ha/year) and soil carbon stocks (39.52-41.16 t/ha/year). The studied weed also has the ability to increase soil carbon stock up to 119%.

“…Umumnya, biomasa tanaman tersusun atas 45%-50% karbon, sehingga pendugaan seberapa besar suatu tanaman mampu menyimpan karbon (sebagai cadangan karbon) dapat diduga dari setengah jumlah bobot kering biomasanya (Maswar et al, 2011).…”

Perkebunan kelapa sawit umumnya memiliki tanaman pengganggu yang disebut gulma, dua jenis yang paling umum adalah Nephrolepis biserrata dan Asystasia intrusa. Gulma ini berpotensi untuk dijadikan tanaman penutup tanah di lahan kelapa sawit karena dinilai memiliki efek yang menguntungkan terutama dalam hal kontribusi bahan organik dalam bentuk cadangan karbon tanah. Tujuan dari penelitian ini adalah untuk menganalisis potensi sumbangan karbon tanah Nephrolepis biserrata dan Asytasia intrusa sebagai tanaman penutup tanah di perkebunan kelapa sawit. Penelitian dilakukan dengan rancangan petak terbagi, yaitu pada petak utama digunakan umur tanaman kelapa sawit, sedangkan anak petak berupa pemeliharaan Nephrolepis biserrata dan Asystasia intrusa, masing-masing perlakuan diulang sebanyak 3 kali. Parameter yang diamati adalah berat kering, kecepatan dekomposisi dan potensi cadangan karbon. Hasil penelitian menunjukkan Nephrolepis biserrata menghasilkan biomassa seberat 21,2 - 27,1 ton/ha, lama proses dekomposisi (30-60 hari), karbon dari tanaman (0,9 ton C/ha/tahun) dan stok karbon tanah (14,7-15,7 ton/ha/tahun). Sedangkan Asystasia intrusa menghasilkan biomassa seberat 17,6 - 17,9 ton/ha, lama proses dekomposisi (30-60 hari), karbon dari tanaman (0,9 ton C/ha/tahun) dan stok karbon tanah 13,2-13,9 ton/ha/tahun.

“…N. biserrata's biomass carbon stock was meager compared to oil palm fronds, M. malabathricum and Cycas sp. which reported to be as much as 9.4-12.2 ton/ha/year (Maswar 2009;Maswar et al 2011), and tropical forest in Asia of 40-250 ton/ha (Lasco 2002).…”

Abstract. Satriawan H, Fuady Z, Ernawita. 2021. The potential of Nephrolepis biserrata fern as ground cover vegetation in oil palm plantation. Biodiversitas 22: 4808-4817. Nuisance plants or weeds are commonly found in agricultural landscapes including in oil palm plantations. Despite being considered as weeds, several of them have the potential to be used as ground cover vegetation including Nephrolepis biserrata (Sw). Schott. This fern species exhibits beneficial characteristic as ground cover plant especially in terms of the contribution of organic matter and soil moisture through the prevention of evapotranspiration. The objective of this research is to explore the potential of N.biserrata as ground cover vegetation in oil palm plantations based on the assessment of its ecological characteristics regarding the growth and decomposition rate, tolerance to shade, organic contents and carbon accumulation. The split plot experimental design was used with the age of oil palm plants was used as main plot while in the sub-plots the spacing of N. biserrata was used at three varying distances 10x10cm, 20x20 cm, and 30x30 cm, each treatment had three replicates. Nine parameters observed were the percentage of growth, the percentage of ground cover, plant height, fronds number per plant, leaves number per plant, Leaf Area Index, dry weight (g), nutrient content in plant tissue, and potential carbon stock. Results showed that N. biserrata showed rapid growth in covering the ground surface (8-12 weeks after planting), had rapid decomposition rate (30-60 days), tolerant to shading which was characterized by the highest percentage of growth up to 81.16% and covering area up to 95.9%, accumulated organic contents of N (1.23-1.53%), P (0.18-0.22%), and K (1.4-1.67%), respectively. In addition, total dry weight biomass obtained was 27.1 ton/ha, accumulated carbon in plant of 0.9 tons C/ha/year, and amount of soil carbon stock 76.4-97.4 tonnes/ha/year. The results of this study suggest that Nephrolepis biserrata is a potential plant to be utilized as a ground cover plant in oil palm plantations.
