Abstract

Tunder different levels of saline water. AAS produced from shrimp shells wastes (deproteinization process). For achieve this purpose, AAS added at rates 0 (distilled water),1000,1500 and 2000 mg/L under 50 mM NaCl, 75 mM NaCl and 100 mM NaCl as compared to control (tap water). The plants sprayed by AAS at 25, 40, 55 and 70 days of sowing. The results obtained that there is a negative correlation between soil salinity and soil organic matter (r = - 0.814). Also, irrigated faba bean plants with saline water gave a significance reduction in growth parameter (plant height, number of seeds per plant, and number of pods per plant) and productivity. Furthermore, there is a negative correlation between soil salinity and protein content (r = - 0.645) and significance decrease in N, P and K concentrations. While foliar application of AAS recorded a significant increase in growth parameters and productivity. The highest percent increase of grain and straw yield were 71.94% and 49.05% at 50 mM NaCl; 102.36% and 41.8% at 75 mM NaCl, and 137.40% and 53.70% at100 mM NaCl, respectively under 2000 mg/L AAS. Foliar application of amino acids solution produced from shrimp waste considered a new technique for improving faba bean growth and productivity under salinity conditions. Furthermore, the application of amino acids solution at rates 1500 mg/L and 2000 mg/L was appeared a significant increase in faba bean productivity and water use efficiency.
