Waktu dan Cara Aplikasi Cendawan Mikoriza Arbuskular (CMA) pada Pertumbuhan Bibit Tanaman Kopi
Abstract: The
effort to increase productivity of coffee plants in long dry season upland of
Ultisol include application of Vesicular Arbuscular Mycorrhizae (VAM) on coffee
plants, because its application only one time and its affect along a life time
of coffee plant in the field. This study aims to determine the exact time and
applications method of VAM on growth coffee seedlings. This study used 10 g VAM/polybag or 800
spores as basic treatment. This study used randomized block design and
experiment arranged in factorial 3 x 5 with three replications. The first
factor was the time of VAM application: given at nursery seedlings (W1), given
at transplanting (W2), and combine of given at nursery seedlings and
transplanting (W3). The second factor was the applications method of VAM:
without VAM inoculant (C0), VAM
inoculant placed around the coffee seedling root up to a depth of 2 cm below
root (C1), up to a depth of 4cm below root (C2), up to a depth of 6 cm below
root (C3), and VAM inoculant mixed with media planting (C4). All data were
analyzed for variance. Data analysis followed by separation of means using LSD
test with significance level of 5%. The resulted showed that both time and
applications method of VAM have affect on growth component and root infection
rate. The best application time was double application, i.e. combine of given
at nursery seedlings and transplanting, and the best applications method was
VAM inoculant placed around the coffee seedling root up to a depth of 2 cm
below root, both of them increased plant height, stem diameter, leaf amount,
long of root, and root infection rate.
