| Abstract | ||
| The study was conducted to evaluate the effectiveness of six isolates of fungi which isolated from compost plant waste as soilless culture media and from root and Rhizosphere of cucumber plants into solublilization of phosphorus in both solid and broth media as one of mechanisms supposed to improve plant growth. The results showed that fungal isolate of A. niger (A-D-1) shown a clear halo zone around their colony in all solid media PVK , NBRIP and NBRIY, while the fungal isolate A. fumigatus (A-7) shown a clear halo zone around colony only in NBRIP solid media . Also, the results showed that fungal isolates A-D-1 and A-7 reduced acidity (pH) in all broth media PVK , NBRIP and NBRIY in both shaking (120 r / min) and static incubation conditions, where isolate A-D-1 showed decrease in acidity average 3.94 , 2.47 and 2.59 as well as the fungal isolate A-7, 4.23 , 3.37 and 4.32 , compared with the control treatment which has 6.10 , 6.11 and 6.10 during shaking incubation periods 5, 10 and 15 days respectively. In the static incubation condition, the results recorded that fungal isolate A-J - 1 decrease the acidity to 3.77 , 2.39 and 2.25 , as well as the fungal isolate A-7 to 4.08 , 3.83 and 3.52 , compared with the control treatment to 6.10 , 6.11 and 6.10 during static incubation periods 5, 10 and 15 days , respectively, at 28 C . | ||
