This study was conducted in two successive seasons on Sukkary mango cultivar trees grown in an private orchard at wade El-tequnologia region in Sinai, east Suez canal, Ismailia Governorate to study response of mango trees to organic manure sources (poultry manure , sheep dung and compost) ,olive oil waste water at 25 or 50 L. ree and inoculation the soil with mixed ( N-fixation and phosphate dissolving bacteria) on vegetative growth and nutritional status of mango trees. Compost , olive oil waste water at 25 L. ree and biofertilization as single use or in combination increased all vegetative growth parameters except number of leaves per shoot obtained from poultry manure as single use or in combination with olive oil waste water at 25 L. ree and biofertilization . Leaf macro elements content enhanced by using compost , olive oil waste water at 25 L. ree and biofertilization as single use or in combination except leaf nitrogen and potassium content obtained from poultry manure as single use or in combination with olive oil waste water at 25 L. ree and biofertilization, but poultry manure as single use or in combination with olive oil waste water by 25 L. ree and biofertilization increased leaf micro elements content and organic manure source ,olive oil waste water and biofertilization as single use or in combinations failed to show any distinctive effect on total chlorophyll.
