Azzola is a water fern plant widely distributed in aquatic habitats like ponds canals in temperate and tropical regions. . According to literature survey it is found that Azzola is of nutritive value to live stock, poultry and fish .The present research has been conducted to evaluate the nutritive value of Azolla nilotica plant. The samples were collected from three different locations : White Nile, Sororab and Managil. The samples were sun dried and subjected to chemical analysis (proximate) to determine the different nutrients. The obtained data was subjected to statistical analysis by SAS program. The C.P content differed significantly (p<0.05) between the three locations. The Managel sample securied the highest C.P (38.78%) due to aaddition of poultry manure, followed by Sororab (28.75%) and the least was in White Nile sample (20.17%). The C.F. content also showed significant differences between White Nile, Sororab and Managel samples. The values respectively were 14.73%, 14.48% and 16.20%. The ash contents in % was significantly (p< 0.05) higher in White Nile samle(19.85%) compared to both Sororab and Manage samples (17.52%),(16.04%.). The acid insoluble ash% followed the same trend and the vaues were (3.37%) (2.33%) (1.63%). Both acid soluble ash and ether extract E.E showed non significant in the three samples. NFE was significantly (p<0.05) higher in both White Nile and Sorrorab samples compared with Managl(41.61%) ,(35.47%) ,(25.28(%. .The results also indicated significant difference(p<0.05) in NDF and ADF content with higher level in Managel 62.50% ,Sororab 57.85%,White Nile 45.00% NDF. While ADF Managel 47.50%, ,Sororab 44.10%,White Nile 35.00%. On the other hand invitro digestibility showed non significant difference between the three samples. Considering minerals ,potassium showed non significant difference in both Managel and White Nile samples 11.90,11.55% while significant compared to 10.15% Sororab (p<0.05). The phosphorous content showed significant difference (p<0.05) in the three samples , the highest in Sororab 0.67% Addition of Supperphosphate ,White Nile 0.37% and the least was Managel 0.31%. Calcium content was similar in Sororab and Managel 0.40%, 0.40% while higher in White Nile 0.45% with significant difference. The study concluded that Azzola Nilitca plant is potential natural feed source with simple cultivation and treatment practices like addition of manure will improve it is protein content, while addition of superphosphate improves mineral content
