Abstract

A study was conducted in pots on greenhouse experiment to assess the effect of oxalic acid, phosphate solubilizing bacteria, and farmyard manure and ammonium thiosulfate on the release of available phosphorus from rock phosphate and maize (Zea mays L.) hybrid cultivar TWC 324 growth in clay and sandy soil, using the Completely Randomized Design (CRD) with three replications. Available phosphorus and other parameters were assessed using standard methods. Results were statistically analyzed using the GenStat (11th Edition) statistical software package. The amount of available P in the soil positively related to the fresh, dry weight, shoot and root and the plant length of maize. The highest increase in the fresh- dry weight, shoot and root and the plant length when adding and mixing ammonium thiosulfate and oxalic acid with rock phosphate, either separately or in combination, similarly, a trend in clayey soil.
