| Abstract | ||
| A pot experiment was conducted under greenhouse condition at Giza to study the response of wheat and Sudan grass plants to applica-tion of P and K fertilizers and interaction between them in newly re-claimed soils. Soil samples were collected from EI-Salhia, El-Fayoum and South Sinai. Phosphorus and K fertilizers were added at two rates: 15 and 30 kg P205/fed. and 24 kg K20/fed., respectively alone or in corn-biation. Data showed clearly that dry matter of both wheat and Sudan grass plants grown in Fayoum and South Sinai soils were markedly in-creased by P application at both rates alone or in combination with K fertilizer. In Salhia soil, wheat plants responded significantly to P applica-tion along with K. however, they were not affected by application of P or K individually. Dry matter of Sudan grass grown on the same soil in-creased significantly by addition of P alone at the two rates and by the higher rate when applied along with K. In general nutrients uptake (N, P and K) of wheat and Sudan grass plants grown in Salhia, Fayoum and South Sinai soils gave the high-er values when the combination of the high rate of P and the low rate of K (P2K1 ) was added while the low rate of K alone recorded the lowest increase. | ||
