| Abstract | ||||
| Two pot experiments were carried out during the two successive winter seasons of 2005-2006 and 2006-2007 under the greenhouse of Faculty of Agric., MansouraUniversity to study the effect of salt stress of irrigation water and phosphorus fertilization on faba bean (Vicia faba L.). These experiments were conducted in a spilt plot design the main plots were 4 levels of saline water (360 mg/l (tap water), 1000, 2000 and 3000 mg/l.) and the sub-plots were 4 levels of phosphorus fertilization (0, 13, 26 and 39 kg P.fed-1.) with three replicates .. The Obtained results could be summarized as follow: By increasing salt concentration in irrigation water, number of flowers per plant, the mean value of number of pods per plant, pod setting %, seed index, straw and seed yield, N, P and K uptakes (mg/plant)of straw and seeds of faba bean plant as well as the calculated total uptake (straw + seeds) decreased significantly. Soil addition of P-fertilizer at the rates of 13, 26 and 39 kg P.fed-1. significantly increased number of flower/plant, the mean values of number of pods/plant, fruit setting (%), seed index, straw and seed yield, N, P, and K uptakes (mg/plant)of faba bean seeds and total uptake as compared to P0 (without phosphorus fertilization). An irrigation of faba bean plant with saline water with an addition of P-fertilizer at the levels of this investigation had no significant effect on number of flowers per plant, number of pods per plant, seed index, straw and seed yield, N and P uptakes(mg/plant) by faba bean seeds. Such effect of interaction significantly increased N, P and K uptakes of straw and K uptake (mg/plant) of faba bean seeds during both seasons. | ||||
