Abstract : A greenhouse experiment was conducted to evaluate the effects of N amendments, incubation period and manure type on the dry matter production and its content of N, P and K, in sorghum and to detect recent changes in the chemical properties of the soil as influenced by these parameters. Results revealed that, under all manure types, dry matter yield of sorghum for the first crop was significantly higher than that of the second. Longer incubation periods for chicken and cow manures significantly reduced the dry matter yield compared with the shorter incubation periods. Under all manure types, Nand P uptake in contrast to that of Kwas significantly decreased with prolonging incubation period. Soil organic matter content, C:N ratio and soil N, P and K content, were significantly increased; whereas its pH was reduced; on the application of each of the studied manures. Meanwhile, prolonging the incubation period had negative effects on C:N ratio and on dry matter of the soil and its element contents. Effects on pH, on the other hand were positive. N-amendment showed no significant effects.
