PENGARUH INOKULASI CAMPURAN ISOLAT BAKTERI PELARUT FOSFAT INDIGENUS RIAU TERHADAP PERTUMBUHAN DAN PRODUKSI TANAMAN KEDELAI (Glycine max L. Merr)
Abstract: At this time the
oportunity increasing soybean production still open through optimize the
fulfill of the nutrient of plants. Phosphorus is one of element nutrient
essentiality macro those as very important to growth and development of plants.
The existence it in land abundance, but the concentration P who are get reserve
by plant is very low. At acid land P bunching aluminum (AI) and iron (Fe)
meanwhile in land Alkhalin P bounded calsium (Ca). The increasing efesiency of
supply fosfat at plant can effort with exploit microorganism soluble phosphate
group. Test potential solubility P by BPF isolated from peat soil Biosphere
Reserve Giam Siak Kecil Bukit Batu, Riau. Test was conducted and taken in
semi-quantitative which able to dissolve Ca3 (PO4) 2, FePo4 and phosphate rock.
However adaptability and potential dilution BPF origin peat soils of Riau
indigenus inoculated soybean in mineral soil until now unknown. This research
was conducted in order to determine the effect of inoculation BPF indigenus
Riau toward growth and yield of soybean. The study was conducted in factorial
experiment using completely randomized design (RAL Factorial), as the first
factor is soil treatment consisting of two levels ie: T0: soil without
sterilization, T1: sterilized soil. The second factor is the provision isolates
BPF which consists of 4 levels, namely: B0: without inoculation, B1: 2 isolates
BPF (BB_UB6 and BB_K9), B2: 3 isolates BPF (BB_UB6, BB_K9 and BB_K2), B3: 4
isolates BPF (BB_UB6, BB_K9, BB_K2, and BB_HS13). The results showed soil
sterilization decrease the number of primary branch becomes 5.67 and 1.49 g dry
weight of the plant. The fastest time of harvest occurs in plants without
inoculation of sterile soil that is 78.78. The highest weight of 100 seeds
produced by the plant without inoculation of sterile soil that is 13.17 g.
