Abstract:
An experiment has been conducted at green house of Agriculture Faculty, Universitas Padjadjaran, Jatinangor West Java, Indonesia elevated at 782 m above sea levels. The aim of this experiment was to find out the effect of phosphate solubilizing bacteria and organic fertilizer on phosphatase, P available, P uptake and growth up of sweet corn on Andisols from Lembang, West Java Indonesia. Randomized Block Design (RBD) was used in this experiment with twelve treatments and three replications. The treatments were three isolates (Bacillus mycoides, Bacillus macerans and`Pseudomonas pseudoalcaligenes)with combine organic fertilizer were cow manure fertilizer and green manure. The result shows that phosphate solubilizing bacteria and organic fertilizer increased soil phosphatase and P-available significantly. The treatments did not have a significant effect on the growth of sweet corn on Andisols. Isolate of P. pseudoalcaligenes combined with green manure gave the highest to soil available P.
