SERAPAN FOSFOR, PERTUMBUHAN DAN PRODUKSI BEBERAPA VARIETAS KEDELAI (Glycine max L. Merril) YANG DIBERI PUPUK FOSFOR
Abstract: The soybean plants
need a phosphorus in a great quantity for growth and production. Phosporus is
one of essential nutrients for plants, but its availability in soil is tended
to decrease. Therefore, the effective step to increase soybean production is
using the soybean varieties with high productivity that can survive in the poor
soil of nutrients P. This study aimed to examine the effect of fertilizer P to
P uptake, growth and soybean varieties production. The eksperiment was
conducted in an experiment station of Faculty of Agriculture, University of
Riau lasted for 6 month started on April 2013 to August 2013. Four soybean
varieties are Anjasmoro, Grobogan, Argomulyo and Burangrang planted with three
level of dosage of fertilizers, there are 0 kg P2O5/ha, 25 kg P2O5/ha, 50 kg
P2O5/ha. The parameter of observation include the phosphorus uptake, height
plant, days of flowering, days of harvesting, weight of 100 seeds, number of
seed per plant and result per m2. This study result indicate that the best P
uptake are Anjasmoro and Argomulyo on 25 kg/ha fertilizer P but Grobogan and
Burangrang on fertilizer P as much as 50 kg/ha. Giving the fertilizer P can
increasing the growth and production on a certain varieties, while another
varieties can’t showed the effect of giving fertilizer.
