Pengaruh Beberapa Dosis Pupuk Fosfor (P) Terhadap Mutu Benih Berbagai Kultivar Kedelai (Glycine max L. Merril) Selama Pengisian dan Pemasakan Biji
Abstract: An experiment has
been designed to investigate the impact of Phosphorous (P) fertilizer on seed
quaaliti during seed development of several Soybean (Glycine max L. Merrill)
cultivars. The field experiment was carried at University of Riau Agriculture
Experiment Station using a complete randomized block design with three
replicates. Soybean cultivars such as Willis, Malabar, Kipas Putih and line
KM-19-BE were planted in three rates of P fertilizer; ie P0 = 0 kg P2O5as a
control, P1 = 25 kg P2O5, and P2 = 50 kg P2O5 per hektare. Seed quality
including seed viability and seed vigor was observed at 10 days interval from
20 to 50 days after anthesis (DAA). It was found that seed quality was very low
at early stage of seed development and tent to reach its maximum value as seed
matured. Addition of P fertilizer to the plant increased some components of
seed quality at early stage of seed development until 40 DAA. The values of
seed viability and seed vigor were higher in seed harvested from plant
fertilized by P than control, mainly for seed obtained at early seed
development. This results indicated that P fertilizer application would improve
seed quality especially of seed harvested at early seed development of some
soybean cultivars.
