Abstract
Research results on the effect of potting mix to growth of Sophora tonkinensis Gagnep:
Germination rate of Sophora tonkinensis Gagnep formula 3 (Topsoil + 15% symbiotic fungal soil + 10% manure + 2% Super phosphate), formula 4 (Topsoil + 20% sand + 20% coconut + 2% Super phosphorus) has no difference (a) and reaches the highest (96.05 - 96.75%) and is higher than the control formula (Topsoil), formula 2 (Topsoil + 10% manure + 2% Super phosphate), formula 5 (Topsoil + 10% sand + 10% coconut + 2% Super phosphate) is sure at 95% confidence level.
The germination time of Sophora tonkinensis Gagnep in formula 4 and formula 5 (a) is higher than that of formula 3 (b) at 95% confidence level. The germination time in formula 1 (CT1), formula 2 (CT2) (ab) does not differ from that in formula 3 (b), formula 4 & formula 5 (a) in Duncan's comparison method
The number of foliage / plant Sophora tonkinensis Gagnep in formula 3 (a) is highest; then in formula 4 & formula 5 (b) and the lowest in formula 1 (c) is certain at the 95% confidence level.
The height of Sophora tonkinensis Gagnep in formula 3 (a) is highest; then in formula 4 & formula 5 (b) and the lowest in formula 1 (c) is certain at the 95% confidence level.Keywords
