JUNGJUNGAN RIO CHIRISTIAN, NIM. 1110247002. “Seed Development and Yield
Potential Of Three Soybean Varieties With Effect of Gibberellins”, Supervised by Prof. Dr.
Ir. Aslim Rasyad, M.Sc and Dr. Agr. Ir. Tengku Nurhidayah.
Plant growth regulator play an important role in contributing internal mechanisms of plant
growth by interacting with some metabolic process, so that it could be required in enhancing
crop production. The objective of this research was to observe the effect of giberelin on seed
development, yield potential and seed quality of three soybean varieties. A field experiment was
conducted and arranged in split plot design with giberelin concentration as main plot and
soybean varieties as subplot. Gibberellin concentration used consisted of 0 ppm, 125 ppm and
250 ppm. Three Soybean varieties were Grobogan, Wilis and Kaban. Parameter Observe were
seed water concentration, seed dry weight, effective filling period, number of poods per plant,
grain weight per plant, grain yield m-2, 100-seed weight, seed protein and oil content. The result
of this research indicated that application of Gibberellin did not significantly affect soybean seed
development but increased soybean yield potential and slightly improved the quality of soybean
seeds in 3 varieties tested (125 ppm).
