This study aims to evaluate and determine the optimal combination dose of biochar and chicken manure fertiliser on garlic growth parameters and yield on alluvial soil. This study was conducted in South Pontianak District, Pontianak City. The research method was a Complete Randomised Design (CRD) Factorial. The first factor was the biochar dosage (5, 10 and 15 tonnes/ha) and the second factor was the chicken manure dosage (10, 20 and 30 tonnes/ha), resulting in 9 treatment combinations, namely b1p1, b1p2, b1p3, b2p1, b2p2, b2p3, b3p1, b3p2, and b3p3. The combination of biochar and chicken manure had a significant effect on the morphology (bulb diameter and plant height) of garlic in alluvial soil. Among the various variations, the b2p3 treatment (10 tonnes/ha of biochar and 30 tonnes/ha of chicken manure fertiliser) was identified as the most effective dose for optimising plant growth beyond the achievements of other dose combinations.</p> Sutikarini, Mulyadi Hak Cipta (c) 2025 https://creativecommons.org/licenses/by-nc-nd/4.0 https://jurnal.upb.ac.id/index.php/agrosains/article/view/611 Thu, 09 Oct 2025 00:00:00 +0700
