Pertumbuhan Dan Hasil Jagung (Zea Mays L.) Pada Tanah Ultisol Yang Diaplikasi Kompos Solid Dan Fly Ash Batubara

---

ABSTRACT
Maize (Zea mays L.) is an important food crop in Indonesia, serving both as a food
source and livestock feed. Declining maize productivity is often linked to low soil
fertility, especially in marginal soils such as Ultisols. This study aimed to examine
the effects and interaction of solid compost and coal fly ash application on maize
growth and yield, as well as to determine the optimal dosage for each treatment.
The research was conducted at the UPT Experimental Field and Soil Science
Laboratory, Faculty of Agriculture, University of Riau, over a seven-month period
(June 2024–January 2025) using a factorial Completely Randomized Design (CRD)
with two factors: solid compost dosage (0, 5, and 10 t.ha⁻¹) and coal fly ash dosage
(0, 5, and 10 t.ha⁻¹). The parameters observed in this study included the chemical
analysis of solid compost, chemical analysis of coal fly ash, baseline soil chemical
properties, plant height, stem diameter, time to tassel emergence, time to silking,
days to harvest, ear weight with husk per polybag, and ear weight without husk per
polybag. Results showed a significant interaction between solid compost and fly
ash in influencing ear weight without husk per polybag. Solid compost application
significantly affected all observed parameters, while fly ash application had no
effect on tassel emergence time and ear weight with husk per polybag, but did
influence other parameters. The best results for both growth and yield components
were achieved with a dosage of 5 t.ha⁻¹ for both solid compost and coal fly ash.
Keywords: Soil Fertility, Chemical Analysis, Food Source, Marginal Soils
