| ABSTRACT The aim of this study was approach a maximum yield of Melilotus plants by integration between bio-fertilizers and mineral fertilizers especially P fertilizers. A field experiment was conducted for two successive years (2018 and 2019) using completely randomized field experiments with three replications for each treatment in El-Hamam area, Marsa Matrouh Governorate, Egypt (between the intersection of the longitude 30º 34' 51'' N and the altitude 30º 15' 40'' E). Melilotus elegans was the investigated crop, sown in the in plots (3×4m) in rows. Biofertilization treatments were Rhizobia, phosphate dissolving bacteria (Bacillus megatherium and Pseudomonas putida). The mineral fertilization was applied as a general treatment using three rates of 15 , 30 and 45 kgP2O5/fed. as calcium super phosphate(15.5%P2O5) mixed with the soil during soil preparation . N and K fertilizers were added at one rate of 80 kg N/fed. as NH4NO3 and 40 kg K2O as potassium sulphate divided into two equal doses applied at seedling and after cut one stages. The dose of 10m3 organic manure was added. Obtained results clearly showed that, mixed biofertilization treatment recorded highest values for yield and its components as well as total N,P and oil % in content of shoot and leaves of Melilotus plant for two cuts and during two growing seasons followed by P.putida, and then PDB while mineral P increase yield parameters with increase rates of P up to P3. From the obtained results we can cocluded that, mixed biofertilization treatment combined with P fertilization was superior treatment for Melilotus plants under El-Hamam soil conditions . | ||
