AMELIORASI TANAH GAMBUT DENGAN BERBAGAI LIMBAH INDUSTRI TERHADAP PERTUMBUHAN DAN HASIL DUA VARIETAS JAGUNG (Zea mays L.)
Abstract: This study aims to
get ameliorant formulations of various industrial wastes most suitable for the
growth and yield of maize varieties Earth-3 and NK-212 in peatland, research
design using a split plot design with 12 combination and each treatment was repeated
3 times. The main plot of treatment consists of: (V1): Varieties of Earth-3,
(V2): Varieties of NK-212. Treatment subplot, which consists of six
formulations ameliorant, namely: F1 (60% TKKS + 20% ATKS + 10% dregs + 10% fly
ash), F2 (60% TKKS + 10% ATKS + 20% dregs + 10% fly ash ), F3 (60% TKKS + 10%
ATKS + 10% dregs + 20% fly ash), F4 (40% TKKS + 30% ATKS + 10% dregs + 20% fly
ash), F5 (40% TKKS + 20% ATKS dregs + 30% + 10% fly ash) and F6 (40% + 10% TKKS
ATKS dregs + 20% + 30% fly ash). The data obtained were statistically analyzed
using analysis of variance (ANOVA) followed by HSD test at a rate of 5%.
The results showed that the peat soil improvement ameliorant consists of
various formulations, is 40-60% TKKS, ATKS 10-30%, 10-30% and 10-30% fly ash Dregs,
giving real effect to the varieties and formulations ameliorant. Varieties
significantly affect a male flowers and female flowers. Formulation ameliorant
significant effect on plant height and timing of male flowers and female
flowers. Interactions both provide the same effect on all observed variables,
and results from the production of the resulting show, cob was formed to
produce cob big and long, the number of lines of neatly arranged and the seed
is fully charged and the skin covering the cob well (± 98%) is in conformity
with description. This is because the availability of nutrients that keep
running from ameliorant provided, so that the nutrients are available to be
fairly balanced.
Varieties of Earth-3 with formulations F6, better used for peat because
varieties of proven Earth-3 and F6 formulations were able to accelerate the
emergence of male flowers and female flowers, thus spurring the generative
plant growth, by accelerating the maturation of seeds so as to accelerate the
harvest.
