dc.description.sponsorshipA greenhouse pot experiment was set up to find the effect of added phosphorus on the availability and uptake of P, Mn and Fe by rice plant under flooded conditions. Two soil series Akuse and Amo (verti- sol and Inceptisol, respectively) were used. The experiment was of a simple factorial design compri¬sing of four levels of P with and without rice plant on both soils under continuous submergence. Samples of growing rice plants, supernatant soil solution, and the wet soils were taken for laboratory analysis at one, two, three, five, six and eight weeks of age during an eight week period. The soluble P, Mn and Fe in the supernatant liquids, the uptake of these ions by the plant and the extractable Mn and Fe from the wet soil were determined. In most of the treatments, Ps Mn and Fe followed similar trends in both cropped and uncropped soils.In the majority of the treatments, the highest values of nutrients were obtained in the first week with mark¬ed decrease in the second or third week after trans-planting/submergence. In the case of iron in the plant material, the marked decrease was in the fifth week. The concentration of the nutrients in the treatments generally decreased to about the lowest level in the eighth week except Mn and Fe in the wet soil treatments and Fe in the plant material which increased then.Changes in availability may have been due to reduction or oxidation of phosphate compounds of Mn and Fe, solubility or precipitation of Ca phos¬phate, hydrolysis, or complex forming tendencies of Fe and Mn, resulting in availability or precipi¬tation of P, Mn and or Fe which in turn sometimesv naffected the uptake by the plant.The two soils studied were found to be signi¬ficantly different in release of the nutrients under study as affected by the addition of triple super¬phosphate fertilizer. These differences were reflec¬ted in the yield of the rice crop in which Amo series did much better than Akuse series.en_US
