Abstract

The greenhouse experiment aims to apply and study the effect of selected and mixed treatments (oxalic acid, phosphate solubilizing bacteria, farmyard manure, and ammonium thiosulfate) with rock phosphate on the productivity of the fresh and dry weight, as well as the uptake of different elements (nitrogen, phosphorous, and potassium) on the soybean (Glycine max) (legume plant) cultivar (Giza
111) crop in both sandy and clay soils, using the Completely Randomized Design (CRD) with three replications. Results were statistically analyzed using the GenStat (11th Edition) statistical software package. The results showed that the highest increase in the fresh-dry weight, shoot and root, plant length, and nutrient uptake when adding and mixing ammonium thiosulfate and oxalic acid with rock
phosphate, either separately or in combination, while the soybean plant in the sandy soil similarly, a trend in the clayey soil.
