Abstract
Inceptisol is a type of young soil that has several problems, namely low levels of N, P, K nutrients, susceptibility to erosion, and pH instability. This problem can affect crop yields, for example shallot plants. Improvement efforts to increase Inceptisol soil fertility by providing soil amendments. Research objectives: To examine the provision of amendments and combinations of goat manure, dolomite, zeolite and Trichoderma sp decomposer. the most effective in improving the chemical characteristics of inceptisol, analyzing the level of nutrient availability, especially potassium (K) due to the administration of Trichoderma sp. on amendments to goat manure, dolomite, and zeolite. Examining improvements in the chemical characteristics of inceptisol on the growth and production of shallots. The research was carried out at the experimental garden of the Center for Tropical Horticulture Studies (PKHT), Bogor Agricultural Institute (IPB) located at RT.05/RW.05, Pakuan, Kec. South Bogor, Bogor City, West Java, uses the two-factor RALF method. The first factor is Type and Combination of Amendments (P) which consists of 7 levels, namely P0 (Control), P1 (Dolomite 2 tons.ha-1), P2 (Goat Manure 10 tons.ha-1), P3 (Dolomite 2 tons. ha-1 + Goat Manure 10 tons.ha-1), P4 (Dolomite 2 tons.ha-1 + Goat Manure 10 tons.ha-1 + Zeolite 2 tons.ha-1), P5 (Dolomite 2 tons.ha- 1 + Goat Manure 10 tons.ha-1 + Trichoderma sp. 20 kg.ha-1), P6 (Dolomite 2 tons.ha-1 + Goat Manure 10 tons.ha-1 + Zeolite 2 tons.ha-1 + Trichoderma sp. 20 kg.ha-1). The second factor is Shallot Plant Variety (J) which consists of 2 levels, namely J1 (Top Variety), J2 (Sakato Variety). Research results: The provision of amendment and decomposer treatment had a significant effect on the chemical characteristics of P6 treatment inceptisol (Dolomite, Goat Manure, Zeolite, and Trichoderma sp.) which gave the best results compared to other treatments. Meanwhile, the treatment of shallot plant varieties had no direct effect on the chemical characteristics of inceptisol
