| Abstract | ||||
| Two field experiments were conducted during two successive summer seasons of 2003 and 2004 at El-Baramoon Experimental Farm; near El-Mansoura city; Dakahleya Governorate; Egypt to study the effect of P-fertilizer in mineral or bio-form and Fe-EDTA in foliar way on chemical composition, yield and its component for Nebrasca cv. of snap bean plant (phaseolus vulgaris L.). 16 treatments were arranged in a complete randomized design plot with 4 replicates, P2O5-levels 0,30,60 and 90 kg/fed. were studied in the presence or absence of phosphate dissolving bacteria (PDB) inoculation and Fe-EDTA (300 ppm) in foliar way. Obtained results can be summarized as follow: 1- Application of P-levels solely tell the rate of 60 kg P2O5/fed. significantly increased P-content in the leaves of snap bean plant; increasing the rate of P2O5 up to 90 kg/fed. led to a depressive effect in the same character. On the other hand, P-content in snap bean stems significantly increased at any level of P-fertilizer under study. 2- Fe-content in snap bean plant tended to decreases in the leaves and increases in the stems as the level of P2O5 was increased. 3- The contents of P and Fe in the parts of snap bean plant has been reflected on the values of P/Fe ratio which were increased in the leaves and decreased in the stems as the level of P-addition solely was increased. 4- (PDB) inoculation for the seeds of snap bean plant grown under the levles of P2O5 0, 30 and 60 kg/fed. led to an increase in the contents of P and Fe in the parts of the plant than those obtained for the same levels of P2O5 solely. Increasing the rate of P2O5 from 60 to 90 kg/fed. had a depressive effect on the activity of (PDB). 5- Adding of Fe in foliar way for the plants treated with P levels under study either with or without (PDB) inoculation has been corrected the depressive effect of heavy phosphorus application. Then, P/Fe ratios tended to constant in the leaves of snap bean plant which led to increasing in the yield of snap bean plant. | ||||
