Abstract

Aglaonema commutatum or aglaonema is an ornamental leaf plant. In Indonesia, it is populary referred to as Sri Rejeki. Aglaonema variety Lady Gaga has high aesthetic value and demand by many people because its distinctive patterns and colors. The success of aglaonema cultivation is influenced by the composition of growing medium used. This study aims to determine the best planting medium composition through a comparative study. The research was conducted from July to September 2023 in Palembang City. Was arranged based on Randomized Block Design, consisting of three treatments: volcanic sand (M0), volcanic and rice husk 1:1 v/v (M1), and volcanic sand and risk husk 1:2 v/v (M2). The research data were analyzed using Analysis of Variance (ANOVA). The result of this study showed that the use volcanic and rice husk 1:1 v/v (M1) significantly enhanced all growth parameters, including the number of leaves, leaf length, leaf width, and new leaf growth; and parameters related to visual color and quality grade, namely parameters color, brightness, shape and size, also aglaonema leaf motif. In addition, direct sunlight also effect the color, brightness, and leaf motif of aglaonema var. Lady Gaga which is increasingly fading. Therefore, it is recommended that aglaonema cultivation be carried out in shaded areas that not exposed to direct sunlight.

Abstract

The efforts to increase productivity of rubber plantations can be carried out through polyculture planting patterns rubber of corn and sorghum. The aim of this research is to determine the rubber response and the growth of corn and sorghum intercrops with modified planting spacing. The research was conducted at the Rubber Research Facility, Faculty of Agriculture (3◦14′2′′S 104◦38′12′′E), Universitas Sriwijaya, Indralaya, Ogan Ilir, South Sumatera. The research was conducted in two experimental units using a  randomized block design with four replications. Planting spacing was as treatment. There were three plant spacings for corn, the treatment spacing, which consists of three levels, namely 75 cm × 25 cm (JT-J1), 75 cm × 30 cm (JT-J2) and 75 cm × 35 cm (JT-J3). Meanwhile, the spacing for sorghum were as follows 75 cm × 25 cm (JT-S1), 75 cm × 50 cm (JT-S2), 75 cm × 75 cm (JT-S3). The results of research on polyculture of rubber plants with plant spacing treatment had a positive effect on corn and sorghum crops. The  growth and production of corn crops is significantly increased with a planting spacing of 75 × 35 cm for corn and 75 × 75 cm for sorghum was the optimal planting distance, as reflected in the growth of stem circumference, leaf greenness, stalk weight, and weight of 100 grains.
