COMPARATIVE STUDY BETWEEN BIOFERTILlZTAION AND SULPHUR ON AVAILABILITY OF ADDED PHOSPHORUS TO FABA BEAN PLANTS UNDER HIGH PH SOIL CONDITIONS
Faba bean is one of the most important crops as a protein source for human and livestock. It's consumed as green pods in the vegetable varieties or dry seeds in the others. The agricultural practices clearly affect green pods and dry seeds quality. Phosphorus is one of the most vital elements for living organisms and plant production. High pH soils affect phosphorus availability. The objective of the present study is to investigate the effect of biofertilization and sulphur on faba bean seed and straw yields, hundred seeds, weight, phosphorus uptake and protein content. Two field experiments were carried out at Sakha Agric. Res. Sta. Farm during two successive winter seasons of 2001/2002 and 2002/2003 using faba bean (Vicia faba) var. Giza 461. split plot design was used. The main plots were allotted for two phosphorus levels of 15 and 30 kg P20S fed:'. The sub plots were randomly assigned to four treatments: 1- without application (check treatment ), 2- Inoculating faba bean seeds with phosphate solubilizing bacteria (Bacillus megatherium var. Phosphaticum), called (Phosphorin), 3- Inoculating faba bean seeds with mixture of non-symbiotic fixing bacteria (Azospirillum, Azotobacter and Bacillus) called (microbin). and 4-Application of 120 kg fed.-' sulphur to the soil before sowing. The other recommended agricultural practices were followed. The results can be summarized as:
The highest faba bean seed and straw yields were obtained with 15 kg P20S fed:'. Inoculating faba bean seeds by microbin as a biofertilization gave the highest seed and straw yields with the two studied phosphorus levels. Inoculating faba bean seeds with phosphorin as a biofertilization achieved the highest hundred seeds, weight and phosphorus uptake by the seeds and straw. Microbin had the highest protein content in the seeds, as well as phosphorus use efficiency.
