Efektivitas Penyiraman Dan Media Tanam Terhadap Pertumbuhan Tanaman Tomat (Solanum Lycopersicum L.)

Abstract

The tomato (Solanum lycopersicum L.) is a horticultural commodity of significant economic value, widely utilized for both household consumption and the food processing industry. Tomato production in South Sulawesi declined from 65,919 tons in 2022 to 64,804 tons in 2023. One approach to enhancing the growth and production of tomato plants is through the management of irrigation intervals and the use of appropriate growing media. This study aimed to determine the effect of irrigation intervals and types of growing media on the growth and production of tomato plants. The research was conducted from August to November 2025 at an experimental site located on Jalan Ganggawa, Maritengngae District, Sidenreng Rappang Regency. A factorial Randomized Block Design (RBD) with two factors was employed. The first factor was the type of growing medium: soil (M1), soil + rice husk charcoal (M2), and soil + sawdust (M3). The second factor was the irrigation interval: daily (P1), every two days (P2), every four days (P3), and every six days (P4). The parameters observed include plant height, leaf area, stem diameter, number of branches, number of fruits, age at flowering, age at harvest, and fruit weight.The results indicated that the irrigation interval treatments did not have a significant effect on the growth and production of tomato plants. Similarly, the types of growing media did not show a significant effect on any of the observed parameters. Furthermore, there was no significant interaction between the irrigation intervals and the types of growing media regarding the growth and production of tomato plants.
