| dc.description.abstract | The aim of this experiment were to evaluate the eflect of rock phosphate application and combination phosphatesolubilizing bacteria and farm yard manure on soil available P and growth of soybean on UItisol $-om Kentiong village, Banten province. Factorial experiment design with two factors was used in randomized complete block design with three replications. %first factor was rock phosphate i.e. : 0, 30, 60, and 90 kg P/ha, and the second factor was combination of phosphate solubilizing bacteria (PSB) and farm yard martwe (FYM) i.e. : without PSB and FYM (control), PSB (Pseudomonas jluorescens), FYM 10 t/ha, and PSB+FYM Results indicated that significant positive eflect of rock phosphate and combination of PSB and FYM application occurred on soil available P, number and dry weight of n&, dry wight of rod and shoot. Rock phosphate application with rates of 30, 60, 90 kg P/ha increased soil available P 247%, 356% and 592% respectively compared to without P. Phosphate-solubilizing bacteria, farm yard marwe and PSB+FYM increased 27%, 330% dun 48% respectively compared to confrol. Phosphate-solubilizing bacteria and f m yard manure combination with phosphate rock 30 kg P/ha dosage increased dry weight of soybean shoot 29% compared to control. | id |
