RESPON TANAMAN KACANG TANAH (Arachis hypogea L.) TERHADAP PEMBERIAN PUPUK FOSFOR DAN ASAM TRIIODOBENZOAT
Abstract: Triiodobenzoic acid
(TIBA) is a plant growth regulator that may accelerate the change of vegetative
growth into reproductive growth by modifiying the ratio of hormones that
already exist. The purpose of this study was to determine the effect of TIBA
and phosphorous fertilizer on peanut (Arachis hypogea L.). This study was
conducted using a split plot design with three replications. The main plot was
three levels of TIBA concentration; ie, 0 ppm, 50 ppm and 75 ppm. Subplot was
four levels of phousphorous fertilizer; ie, 0 kg, 11,5 kg, 23 kg and 34,5 kg
of P2O5. Parameters measured were plant
height, flowering age, number of primary branches, dry weight of plants at 28
days after planting, dry weight of plant at 35days after planting, plant growth
rate, harvest index, pods dry weight per plot and seed weight per plot.The
results showed that TIBA significantly affected pods dry weight and seed weight
per plot, but not significantly affect plant height, flowering age, number of
main branches, dry weight of plants at 28 days after planting, dry weight of
plants at 35 days after planting, plant growth rate, and harvest index.
Application of phosphorous fertilizer only affected harvest index, pod dry
weight and seed weight per plot. TIBA and phosphorous interaction affected pod
dry weight and seed weight per plot. Application of P2O5 fertilizer 34,5 kg per ha and TIBA with
concentration of 75 ppm resulted higher pod dry weight and seed dry weight per
area than other treatments.
