- Summary
- A study was conducted to check upon the uptake of phosphorus by horse- beans under different soil texture, i.e., sand, loamy sand, loam, and clay loam soils. Application of phosphate was made at zero, 150 and 300 kilograms P/sub 2/ C/sub 5/ per feddan (4200 sq meters) as superphosphate of lime. All treatments were subjected to one uniform application of nitrogen and potassium to satisfy the maximum requirements. Three weeks after germination, a new application of phosphate solution tagged with the isotope P/sup 32/ at the rate of 50 ml solution in one mc of calcium monophosphate Ca/sub 3/ (H/sub 2/P/sup 32/ O/sub 4/ )/sub 2/ were a dded per pot. The whole arrangement was designed as complete blocks in split pot sets, in two replicates in the green-house. Plants were harvested four days later and weighed for leaves, stems, and roots, and worked on separately by digestion and solution. Counting of the emitted radiation was made by using a Geiger-Muller counter, at uniform conditions. Data were converted to 1000 count per minute per one gram oven-dry plant tissue. Results obtained proved that phosphorus uptake was tremendously high in sandy soil compared with other soil types. At the same time it was shown that the higher the phosphate application, the higher the phosphate uptake as shown by radiation counts. Roots contained the maximum concentration of P/sup 32/ followed by stems, and then by leaves. (auth)
