| Abstract | ||||
| This work was carried out during two seasons of 2012/2013 and 2013/2014 in the agricultural research center in El Khassasen .The aim of the this study was to investigate the effect of arbuscular mycorrhizal (AM) fungi inoculation with sewage sludge on the growth of Swieteina mahagoni, seedlings. The AM fungi were used as a mixed culture from species of Glomus mosseae, G. etunicatum and G. clarum..The factorial pot experiment was designed in six amount from sewage sludge (control, 250, 500, 750, 100 and 1250 g plant1) with four levels of AM fungi (zero, 150, 300 and 450±10 spores plant-1). The results shown that, the maximum values in all plant growth parameter were recorded in the plant treated with 500g sewage sludge with AM fungi inoculation rate300, 450 spores/ plant and NPK % in plants leaves was obtained from 500g with 300 and450spores/plant of AM fungi inoculation. The maximum amount of plant chlorophyll a, chlorophyll b and carotenoids were found at plants treated with AM fungi by rate 300 spores/ plant with 500g sewage sludge. The addition of AM fungi to sewage sludge had better growth effect and NPK uptake when comparison between treatments. This is due to the mutual positive action of S. mahagoni and AM fungi species that helped to absorb more NPK fertilization from soil. | ||||
