UJI PENGGUNAAN LIMBAH CAIR BIOGAS DAN PUPUK N, P, K TERHADAP PERTUMBUHAN BIBIT KAKAO (Theobroma cacao L)
Abstract: Cacao is a commodity
plantation crops of high economic value and potential as a foreign exchange
earner of the country. Planting medium is one of the factors that affect the
growth of the cacao plants in the nursery, so we need organic fertilizer and
inorganic fertilizer. The objective of this study to know the effect of
bioslurry fertilizerand fertilizer N, P, K and interaction both on the growth
of seedlings of cacao (Theobroma cacao L). Research conducted at the
experimental field of the Faculty of Agriculture, University of Riau, from
January until the month of April 2015. This research was conducted by using
aCompletely Randomized Design (CRD) factorial, the first factor is the
bioslurry fertilizerwith 4 levels (0, 50, 100 and 150) ml/ seedling and the second
factor is N, P2O5, K2O with 4 levels (0, 1, 2, and 3) g/ seedling. The
combination is repeated 3 times so that there are 48 units of trial and each
experimental unit consists of 4 plants, so the total is 192 plants. Parameters
measured were seedling height (cm), number of leaves (pieces), stem circumference (cm), root
volume (ml), leaf area (cm2 ), dry weight (g), and the ratio of root and crown
and root dry weight. Statistical analysis using analysis of variance followed
by Duncan's Multiple Range Test at 5%.The results showed that the interaction
bioslurry fertilizerand treatment and fertilizer N, P, K effect no significant
effect on seedling height, number of leaves, stem circumference, volume root,
leaf area, dry weight, and the ratio of root and crown and root dry weight.
Administration of 100 ml of bioslurry fertilizerand 2 g of N, P, K is the best
treatment on plant height, number of leaves, leaf area and root volume .
