Abstract

The ever-increasing demand for soybeans has not been matched by increased yields. This is partly due to farmers not fertilizing properly. Many farmers apply urea, SP36, KCl, or compound NPK fertilizers at doses that are inappropriate for the plants' needs. Many even fertilize haphazardly. Appropriate fertilization methods are needed. This study aims to determine the effect of some of fertilization methods on soybean growth and yield on Alfisol. This study used a completely randomized block design (RCBD) with five treatments and five replications. PT0 (no fertilizer), PT1 (Farmer's Method: Urea, SP36, and KCl), PT2 (Balanced Fertilization Method: Urea, SP36, and KCl), PT3 (Farmer's Method: NPK Compound Fertilizer), PT4 (Balanced Fertilization Method: NPK Compound Fertilizer). The results of this study show that inorganic fertilizers given in a balanced manner can increase soybean yields from 2.28 g/plant to 13.82 g/plant. The results of this study indicate that the best treatment method, PT2 (Balanced Fertilization Method: Urea, SP36, and KCl), is able to support plant growth and increase soybean yields.

Abstract

This study aims to assess the impact of Organic FertilizerPlus on soil fertility status, nutrient uptake, and soybean yield in Alfisol. The research employs a randomized complete group design (RCGD) with a single factor, consisting of P0 (Control), P1 (Cow dung, 5 tons ha-1 + Zeolite dose of 2.5 tons ha-1), P2 (Cow dung, 5 tons ha-1 + Zeolite dose of 5 tons ha-1), P3 (Cow dung, 5 tons ha-1 + Dolomite dose of 2.5 tons ha-1), P4 (Cow dung, 5 tons ha-1 + Dolomite dose of 5 tons ha-1), and P5 (Cow dung, 5 tons ha-1 + Zeolite dose of 5 tons ha-1 + Dolomite dose of 5 tons ha-1), repeated four times. The results indicate that the application of Organic FertilizerPlus enhances soil fertility status (pH, organic C, CEC, and available P), with the highest values observed in treatment P5, including pH (6.70), soil organic C (6.28 g.kg-1), cation exchange capacity (CEC) (6.85 cmol.g-1), and available P (2.63 mg.g-1). This leads to increased phosphorus uptake, consequently improving soybean yields. The highest soybean yield is achieved by applying Organic FertilizerPlus (P5) at 2.17 t.ha-1.
