Solanum procumbens Lour. is a precious medicinal plant in Vietnam, effective in treating toothache, snakebites, bone pain, alcohol poisoning, especially liver detoxification and hepatitis diseases. The study was conducted in Central Vietnam with the aim of determining the appropriate density and fertilizer dosage for Solanum procumbens Lour. with the local climatic and soil conditions.
The two-factors experiment was arranged in a split-plot design, with 3 replicates; fertilizer arranged in the large plot with three fertilizer dosages and density arranged in the small plot with three density levels.
Results showed that applied fertilizer dosage per hectare was 1.0 tons of NPK 20-15-5 + TE + 5.0 tons of manure + 1.5 tons of biofertilizer + 500 kg of lime powder comprised with the planted density of 50,000 plants per hectare, Solanum procumbens Lour. grew optimally and gave the highest yield, reached 6.03 net dried tons per hectare after five months of planting. Therefore, if we cultivate Solanum procumbens Lour. with this fertilizer dosage and density, it is considered to be suitable for the climatic and soil conditions in the Central of Vietnam.
