CULTIVAR SELECTION AS A TOOL FOR MANAGING SOILPHOSPHORUS AND FABA BEAN YIELD SUSTAINABILITY

| Abstract |
A sustainable agricultural tactics for countering a possible phosphate shrinking should comprise the releasing of legacy soil phosphorus (P), in parallel to lowering P fertilizer load, and increasing the use of recycled P sources with economic crop yield in mind. Therefore, a ?eld trail was conducted to estimate the possibility of choosing the appropriate cultivar as a tool to raise the use efficiency of reserved soil P. Herein, three faba bean cultivars (Sakha-3, Nubaria-1 and Giza-843) were evaluated under ?ve applications of P fertilizer (rock phosphate, super phosphate, Bacillus megaterium, rock phosphate+B. megaterium, and super phos- phate+B. megaterium). Findings showed that the lowest value of estimated available P in soil after harvest was obtained from plots sown by Sakha-3 plants and fertilized with super phosphate+B. megaterium. Plots sown with Nubaria-1 and fertilized by rock phosphate+B. megaterium or B. megaterium (for weight of 100 seeds and seed yield) in addition to super phosphate+B. megaterium (for seed yield) produced the maximum increases. The highest P recovery e?ciency was achieved with Nubaria-1 inoculated by B. megaterium alone. In conclusion, super phosphate+B. megaterium × Nubaria-1 achieve maximum crop returns and secure high short-term recovery of applied P.
