| Abstract | ||
| This study was conducted on ten surface soil samples of Egypt to evaluate the effect of their properties on response of wheat (Ttiticum Aesticum, Sakha 69) and broad bean (Vida Reba, Giza 429) plants to P fertilization. The collected soil samples have wide variation in their physi• cal and chemical properties. A pot experiment was carried out at Bahtim Experimental Research Station. The pots were arranged in a split plot design in five replicates. The pots were treated with KH2F04. 2H20 as P-fertilizer at rates of 0, 20, 40 and 80 ppm P. After 60 and 90 days of germination, the plant sample of one replicate was harvested and the other three replicates were harvested after 140 days. The grains and .seeds In the latter three replicates were separated from the other plant parts. The obtained data show that, dry matter yield of wheat and broad bean plants (g/pot) increased with the increase of added P and growth period. The highest yield of dry matter was found with application rate of P at 40 ppm. In most treatments, the obtained dry matter yield of wheat was more than that of broad bean. The dry matter yield of plants grown on alluvial (non calcareous) soils was higher than that planted on calcareous soils. The relative increase (%) of broad bean dry matter yield was higher than that of wheat dry matter yield. The agronomical efficiency of P-fertilizer increased with the increase of growth period. The highest agronomical efficiency of added P was found with . the application rate of 20 ppm P. The agronomical efficiency of P for wheat plants grown on calcareous soils was higher than that grown on alluvial soils where its values for broad bean plants planted on alluvial soils were more than those for plants grown on calcareous soils. The correlation coefficients (r) between the dry matter yield of either wheat or broad bean and either of silt, clay, total-P. OM or CEC were positive: but negative with either sand, Cite% a EC. | ||
