Early Texas Grano SR 502 to chemical fertilizer of hakaphos, biofertilizer of nitrobein and organic  fertilizerof sheep manure and some its combined effect on growth, bulb yield and quality of onion.Application of the triple treatment of hakaphos + sheep manure+nitrobein caused significantly increases on plant growth characters , bulb yield and its quality (the nutritive value of bulb) in both growing seasons, followed by Hakaphos with  nitrobein and /or  sheep manure  treatments  in  most cases of studied characters.
Conclusively,  it can be recommended from the obtained results that treating of onion plants with the triple treatment of Hakaphos, nitrobein and sheep manure, followed by mixture of Hakaphes and nitrobein or sheep manure enhancing plant growth characters , bulb yield and its components, as well as, the nutritive value of bulbs , in most two growing seasons.
