Abstrak

This study aims to determine the effect of decomposition time, the best fertilizer dose and the interaction between the decomposition time and the dose
of cow manure on the growth and yield of Asystasia gangetica (L.) subsp. Micrantha. The research was conducted at the Greenhouse, Sesetan Research Station, Faculty of Animal Husbandry, Udayana University on Jalan Raya Sesetan Gang Markisa Denpasar. The study was done for about 3 months, using a completely randomized design (CRD) with a factorial pattern. The first factor is the decomposition time of 4 weeks (W4), 2 weeks (W2), without decomposition (W0) and the second factor is cow manure fertilizer at a dose of 0 t ha-1 (D0), 10 t ha-1 (D10), 20 t ha (D20), 30 tons ha -1 (D30). Each treatment was repeated four times, so that there were 48 experimental units. The variables observed were growth variables, yield variables and plant growth characteristics variables. The results showed that there was an interaction between the time of decomposition and the dose on the ratio of leaf dry weight to stem dry weight but did not show any interaction on other variables. Decomposition time of 4 and 2 weeks actually gave a better response compared no decomposition treatment. Increasing the dose of fertilizer can increase the growth and yield of Asystasia gangetica (L.) subsp. Micrantha. It can be concluded that there is an interaction between the decomposition time and the dose of fertilizer on the variable ratio of leaf dry weight to stem dry weight, and the decomposition treatment of 4 weeks (W4) and a dose of 30 t ha-1 gave the best response to the growth and yield of Asystasia gangetica (L.) subsp. Micrantha.
