北苏拉威西椰子种植园的土地没有得到最佳利用;可以种植的商品之一是大豆。本试验旨在研究大豆的生长发育和生产力，并分析椰子下栽培大豆的经济可行性。所用的实验设计是析因随机设计实验。第一个因素是大豆品种，第二个因素是施肥量。所用大豆品种为Dena-1和Anjasmoro，施肥量为（i）推荐量（尿素75公斤，SP36 100公斤，氯化钾100公斤/公顷），（二）根据土壤分析确定的剂量（iii）粪肥+木霉2吨/公顷+生物尿（每周施用）+ NPK 200 kg/公顷;（iv）农民用量。结果表明，在椰子林遮荫条件下，Dena-1品种的产量高于Anjasmoro。产量分别为2，210公斤/公顷和1，882公斤/公顷。推荐用量（尿素75 kg，SP36 100 kg，KCl 100 kg/ha）大豆产量最高。根据农场分析，大豆可以在椰子林下种植和发展为农作物。假设大豆价格为每公斤6，500印尼盾，大豆种植的R/C比率为1.318至1.449。施用有机肥的R/C值最高，而施用推荐施肥量的R/C值最低（1.318）。
The land under coconut plantation in North Sulawesi has not been optimally utilized; one of the commodities that can be cultivated is soybean. The purpose of this experiment was to study the growth and productivity of soybeans and analyze the economic feasibility of soybean cultivating under coconut. The experimental design used was a factorial randomized design experiment. The first factor is the soybean variety, and the second factor is the fertilizer dosages. The soybean varieties used were Dena-1 and Anjasmoro, while fertilization dosage were (i) recommended dosage (Urea 75 kg, SP36 100 kg, and KCl 100 kg/ha), (ii) dosage based on soil analysis (SP36 200 kg/ha and KCl 100 kg/ha), (iii) Manure + Trichoderma 2 ton/ha + bio urine (applied weekly) + NPK 200 kg/ha, and (iv) farmer dosage. The results showed that under shaded conditions of coconut stands, the Dena-1 variety production was higher than Anjasmoro. Productions were 2,210 kg/ha and 1,882 kg/ha, respectively. The recommended dosage (Urea 75 kg, SP36 100 kg, and KCl 100 kg/ha) produced the highest soybean yield. Based on farm analysis, soybeans can be cultivated and developed as a crop under coconut stands. Assuming a soybean price of IDR 6,500/kg, the R/C ratio of soybean cultivation ranged from 1.318 to 1.449. The highest R/C ratio was obtained using organic fertilizers, while the lowest R/C ratio (1.318) was achieved using recommended fertilizer dosages.
