Effect of inoculation with phosphate solubilizing bacteria, organic manuring and phosphate fertilization on peanuts grown on sandy calcareous soil

摘要

In a field experiment in summer 1997 and 1998 on a sandy calcareous soil at the Assiut University Experimental Farm of El-Ghorieb, Egypt, groundnuts cv. Giza 5 were given 0, 15 or 30 m3 farmyard manure (FYM)/feddan, and 0, 50 or 100 (1998 only) kg P/feddan, with or without inoculation with the phosphate-solubilizing bacterium Bacillus megatherium [B. megaterium]. Shoot and pod yields, and N, P and K contents in shoots were highest in inoculated plants with 50 or 100 kg P and FYM. [1 feddan = 0.42 ha.]
