Ameliorants based on local resources are an alternative solution for farmers to sustainably optimise agricultural wastes in horticultural production. This study aimed to determine the effect of residual ameliorant formulation from a local resource (RAF-LR) on the chemical properties of Inceptisols and the production of green beans (Phaseolus vulgaris L.) in Kenagarian Pakan Sinayan, Banuhampu, Agam, West Sumatra. This study used a randomised complete block design (RCBD) with eight treatments and three replications, namely: A=Control; B=[Bamboo biochar(BB)+Tithonia Green Fertilizer(TGF)+Chicken Manure(CM)+Agam Compost(CA) ~10 t ha-1]; C= [BB+TGF+CM ~10 t ha-1]; D=[BB+TGF+CA ~10 t ha-1]; E=[BB+CM+CA ~10 t ha-1]; F=[TGF+CM+CA ~10 t ha-1]; G=Farmer's Tradition(FT) [CM=1.875 t ha-1] and H=Ministry of Agriculture Recommendations(MAR) [CM=10 t ha-1]. The soil samples were from RAF-LR in the previous growing season through polyculture cultivation with an intercropping system between caisim and cauliflower. The effect of RAF-LR significantly affected the chemical properties of Inceptisols [pH, EC, CEC, OC, total N) and green beans production [nutrient plant (N and P) and total yield]. BB+TGF+CA (by 0.6 units pH H2O; 0.51 units pH KCl; 0.173 dSm-1; 0.35% SOC; 0.012% P-plant; 60.75% yield) and BB+TGF+CM (0.123 dSm-1; 22.45 cmol(+)kg-1; 2.19% N-Plant; 74.77% yield) had the most effect from RAF-LR compared to control. A significant positive correlation was observed between soil chemical properties of Inceptisols with green bean production due to the effect of RAF-LR. There was a positive correlation between the total N of Inceptisols and the total production of green bean plants at r = 0.410*. © 2024, Malaysian Society of Soil Science. All rights reserved.
