Key words: Berseem clover, phosphate fertilizers, Pseudomonas, forage yield.
Phosphorous is one of the essential elements which is highly needed by plants to grow and reproduce. Most of farming soils used for trifolium cultivation lack enough phosphorous. In such conditions, it is possible to recommend two main sources for the provision of phosphorous required for the clover plant: phosphorous biological fertilizers and phosphorous chemical fertilizers. In order to investigate the effects of phosphate solubilizing bacteria as biological phosphorous fertilizers and the different levels of phosphate fertilizers on the forage clover, an experiment using a factorial experiment conducted carried out based on completely randomized block design with three replications after rice harvest in Fuman region. The experimental factors included: 3 levels of phosphate (0, 50, 100 Kg/ha as superphosphate triple) and three strains of Pseudomonas putida (M21, M5, M168 strains and control). These factors were investigated on the berseem clover. The analysis of variance showed that the interaction of the bacteria in the phosphorous fertilizer on the fresh forage and the raw protein was significant. Furthermore, the mean comparison demonstrated that, at a level of 100 kg superphosphate fertilizer, the M5 strain produced the maximum yield in fresh forage and the raw protein.
