PENGGUNAAN ASAM TRIIODOBENZOAT PADA BERBAGAI VARIETAS KEDELAI (Glycine max (L.) Merril)
Abstract: Triiodeobenzoic acid
(TIBA) is a plant growth regulator which is expected to synchronize the
partition of dry matter translocation into vegetative and to reproductive
organs. So that substance may be introduce to greater range of crop cultivation
technology to increased yield potential. The objectives of this study are to
look at the effect of TIBA application on growth and production of soybean
varieties and to identify different response of the varieties to various
concentrations of TIBA. A field experiment was conducted by split plot design,
where the application of TIBA 0 ppm, 50
ppm, 100 ppm and 150 ppm as the main plot and three varieties Grobogan, Kaba
and Wilis as subplot. Parameters observed were plant height, internode length
of the main trunk, date to harvest, number of filled pods per plant, number of
seeds per plant, seed weight per plant, harvest index, weight of 100 seeds and
yield per m2. The results showed that application of TIBA 50 ppm shortened
plant height and internodes length of Kaba and Grobogan. It was shown that
application of 100 ppm TIBA could increased yield components and yield per area
compared to control indicating the increasing of dry matter translocation to
the seed.
