Keywords:
Greenhouse, growth, Panax pseudogingsen, coirAbstract
Panax pseudoginseng Wall. is a trational medicine in Vietnam. It was
acclimatized to Lam Dong provine for cultivation. Experiment to evaluate the adaptability to climate zone through mixed coir - soil treatments in Dalat, Lam Dong province. The testing was observed in greenhouse. The experiment was analyzed through the twoway anova analyze and non - parametric Kruskal -Wallis method. After 8 month, the results showed that the best survival rate of P. pseudogingseng is 64% (60% soil+ 40%coir) and 60% (40% soil + 60%coir) respectively. The twoway anova analyze showed that mixed treatment and timely test was effected results of test; in that, the best survival rate was the two mixed treatments 60% soil - 40% coir và 40% soil - 60% coil. Kruskal - Wallis test was showed that p - value < 2.2e - 16 (Sig. = 0,05, Kruskal - Wallis chi - squared = 84.78, df = 4) is much smaller 0,05. So that, at least one significant difference between the mixed - treatments. After 8 month,
two mixed treatments which have the best length of petiole is 20% soil + 80% coir (10,07 ± 1,38 cm (SD)) and 40% soil + 60% coir (8,93 ± 1,36 cm). After the test, the most suitable mixed - treatment for growth of seedlings in the nursery is 40% soil + 60% coir. The analyzes was completed by Rstudio software.
