Abstract

Aglaonema 'Dud Unyamanee' merupakan tanaman hias populer yang menghadapi kendala perbanyakan konvensional yang lambat dan terbatas. Benzyladenine (BA) diketahui dapat merangsang tunas lateral dengan memecah dominasi apikal. Penelitian ini bertujuan menentukan konsentrasi BA terbaik untuk menginduksi tunas Aglaonema 'Dud Unyamanee' secara ex-vitro. Penelitian menggunakan Rancangan Acak Lengkap faktor tunggal dengan empat konsentrasi BA (0, 100, 200, dan 300 ppm). Larutan BA diaplikasikan dengan penyemprotan pada pangkal batang seminggu sekali selama empat minggu. Pengamatan dilakukan hingga 12 minggu setelah aplikasi , meliputi persentase kemunculan tunas, jumlah tunas, panjang tunas, diameter tunas, dan jumlah daun. Hasil penelitian menunjukkan aplikasi BA berpengaruh sangat nyata. Perlakuan BA 300 ppm (P3) menunjukkan hasil terbaik, mencapai 100% tunas muncul pada minggu ke-4 , dibandingkan kontrol (0 ppm) yang hanya 41,67% pada minggu ke-12. Konsentrasi 300 ppm juga menghasilkan jumlah tunas (6,83) , panjang tunas (12,93 cm) , diameter tunas (8,92 mm) , dan jumlah daun (13,58 helai) tertinggi. Disimpulkan bahwa aplikasi BA 300 ppm paling efektif untuk mempercepat inisiasi dan meningkatkan pertumbuhan tunas Aglaonema 'Dud Unyamanee'. ABSTRACT Aglaonema 'Dud Unyamanee' is a popular ornamental plant facing constraints from slow and limited conventional propagation methods. Benzyladenine (BA) is known to stimulate lateral shoot growth by breaking apical dominance. This study aimed to determine the most effective concentration of BA for inducing lateral shoots in Aglaonema 'Dud Unyamanee' via ex-vitro application. The research used a single-factor Completely Randomized Design (CRD) with four BA concentrations (0, 100, 200, and 300 ppm). The solution was applied by spraying the stem base once a week for four weeks. Observations were made up to 12 weeks after application , measuring shoot emergence percentage, shoot number, shoot length, shoot diameter, and leaf count. The results indicated that BA application had a significant effect. The 300 ppm BA treatment (P3) showed the best results, achieving 100% shoot emergence by week 4 , whereas the control (0 ppm) only reached 41.67% by week 12. The 300 ppm concentration also yielded the highest shoot count (6.83) , shoot length (12.93 cm) , shoot diameter (8.92 mm) , and leaf count (13.58). It is concluded that a 300 ppm BA application is most effective for accelerating initiation and enhancing the growth of Aglaonema 'Dud Unyamanee' lateral shoots.

Abstract

Improving oil palm production can be achieved through better cultivation management, including proper nursery practices. The quality of seedlings at the early growth stage plays a crucial role in determining field performance, making efficient fertilization essential from the pre-nursery phase. One of the fertilization technologies developed to improve nutrient uptake efficiency is the application of Controlled Release Fertilizer (CRF). This study aimed to evaluate the effect of CRF compared with conventional NPK fertilizer on the growth of oil palm seedlings. The experiment was conducted for three months using a Completely Randomized Design (CRD) with four treatments: no fertilizer (P0), NPK (P1), NPK + CRF (P2), and CRF (P3). Data were analyzed using ANOVA at a 5% significance level, followed by the LSD test when significant differences were detected. The results showed that treatments P2, P3, and P4 produced better growth responses than the control in all observed parameters, including plant height, number of leaves, leaf greenness, stem diameter, and leaf area. Fertilizer application significantly improved seedling growth, while CRF, either applied alone or in combination with NPK, produced growth responses comparable to conventional fertilization. These findings indicate that CRF has the potential to be used as an effective fertilization alternative to support oil palm seedling growth in the pre-nursery.
