    Abstract

    Research aimed to study the influence of phosphate rock-sulfur (PRS) content and inoculum ratios of biosulfo on P and S update and red onion yield on acid (Alfisol) and alkaline (Vertisol) soils. two factors wavaluated were PRS content (0%, 60%, 80%) and inoculums of A.niger/ P.nalgiovensis ratio of biosulfo (0:0, 1:! and 3:1). As much of 12 kg of soil (Q 2 mm) mixed throughtly with biasulfo, basic fertilizer and manure, put into polybag then watering at field capacity moisture content. one bulb of red onion was planted to each other polybag and incubated in the green house. the experiment arranged in completely randomized design with three replications. variable observed included p and s uptaake, and enion yield. data analized with f test at 5% level of significant influences. the result shows that the increases of PRS content as well as A.niger ratio of biosulfo tend to increases p and S uptake. especially on acid Alfisol. higest p and s uptake and onion yield were achieved with treatment combination of P80|11,P80|31, and P60|11 for Alfisol, and P80|11, P60|11 andP60|11 for Vertisol respectively.
