Abstract

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 study was to study the growth and productivity of soybeans, as well as to analyze the economic feasibility of soybean cultivating under coconut. The experimental design used was a factorial experiment. The first factor is the soybean variety, and the second factor is the fertilizer dosages. The soybean varieties used are Dena-1 and Anjasmoro. Fertilization dosage: (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 + biourine (applied weekly) + NPK 200 kg/ha, and (iv) farmer^s dosage. The results showed that under shaded conditions of coconut stands, the Dena-1 variety production was higher than Anjasmoro. Production respectively 2,210 kg/ha and 1,882 kg/ha. 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 Rp.6.500/kg, 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 using based on soil analysis fertilizer dosages.
