| dc.description.abstract | sub-tropical areas. The quality of essential oils in Indonesia is increasingly
declining. The decline in export volume and low price of vetiver oil is caused by
low production and quality of vetiver oil. Planting vetiver under appropriate
salinity conditions can increase secondary metabolites and vetiver growth so it is
necessary to screen several vetiver ecotypes at various salinity levels.
Salinity is a problem that causes a decline in the production of various
crops in the world, including Indonesia. The application of appropriate strategies
needs to be carried out to reduce the negative impact of salinity on vetiver,
namely technical culture measures with the application of salicylic acid and
mycorrhiza.
This research aims to obtain vetiver ecotypes that are suitable for planting
in salinity conditions and obtain vetiver production with technical culture through
the use of salicylic acid and mycorrhiza in salinity conditions.
Stage 1 of the research was screening several vetiver ecotypes using a
factorial completely randomized design with 2 factors. The first factor is salinity
stress which consists of no salinity, 4 dSm-1 salinity, 8 dSm-1 salinity, 12 dSm-1
salinity, 16 dSm-1 salinity, and 20 dSm-1 salinity, while the second factor is
ecotype which consists of Bogor, Bojonegoro, and Padang, where 3 replications
were made for each treatment.
Stage 2 of the research was technical culture of vetiver in salinity
conditions with salicylic acid and mycorrhiza. At this stage a factorial Completely
Randomized Design was used with 3 factors. The first factor is the best ecotype
and salinity which consists of the Padang ecotype at a salinity of 4-5 dSm-1 and
the Padang ecotype at a salinity of 8-9 dSm-1, the second factor is salicylic acid
which consists of no salicylic acid, 0.5mM salicylic acid and 1 mM salicylic acid,
and the third factor was mycorrhiza consisting of no mycorrhiza, Glomus sp
mycorrhiza and Gigaspora sp mycorrhiza, where each treatment was made in 3
repetitions. The results showed that the best production of vetiver was obtained
with the application of 0.5 mM salicylic acid and mycorrhiza Gigaspora sp.
The research results showed that the Padang ecotype at salinities of
4 dSm-1 and 8 dSm-1 was the best vetiver ecotype based on essential oil production.
The results showed that the best production of vetiver was obtained with the
application of 0.5 mM salicylic acid and mycorrhiza Gigaspora sp. | en_US |
