RESPON BEBERAPA VARIETAS KEDELAI (Glycine max (L) Merril) TERHADAP PEMBERIAN GIBERELIN
Abstract: Plant growth
regulator such as gibberellins () is considered as a crucial part in soybean
cultural practices; however, the information on its beneficial has been
limited. So, this experiment was
intended to look at the impact of on soybean growth and yield components and
the response of different varieties on . A field experiment was arranged in a
split plot design, in which three levels of concentration as main plot and
three cultivars as sub plot. Gibberellins applied were 125 ppm, 250 ppm, and
control. The cultivars used were Kaba, Wilis, and Anjasmoro. Seed of soybean
cultivars was planted in a plot of 3.2 m by 3 m with planting space 40 cm by 15
cm. At 21 days after planting, was sprayed to the plants according to
treatments in which spraying rate of 384 ml every plot. Parameters observed
were crop growth rate, internodes length, days to flowering, filled pod numbers
per plant, seed numbers per plant, grain yield per m2, harvest index, and
100-seed weight. The results showed that application of gibberellin
significantly lengthened main stem internodes,
increased grain yield but decreased
plant growth rate, and 100-seed weight. This results indicate that application of should be used carefully in
soybean cultural practice.
