Two field experiments were carried out in two successive seasons of 2013 and 2014 at the Agricultural Experimental Station of the National Research Centre, EL-Nubaria, Elbehira Governorate, Egypt, to study the effect of three levels of Glutamine (25ppm, 50ppm and 100ppm) spraying in addition the control on growth, yield and pods quality of two bean cultivars (Paulesta and Oxzira). Results showed that using Oxzira cv. gave the highest values of the vegetative growth (number of leaves and number of branches as well as fresh and dry weight of whole plant), total yield, quality and Chemical constituents (Total Free amino acids in leaves and total phenolic acids in pod). Whereas, Paulesta cv. Resulted the highest values of plant length and Total Free amino acids in pods. Spraying bean plants by Glutamine (25ppm, 50 ppm) increased vegetative growth, total yield and quality with no significant difference between 50 and 25 ppm. Whereas, using Glutamine as (25ppm) increased Total Free amino acids in leaves and total phenolic acids in pod but Total Free amino acids in pods highest when using Glutamine (100ppm).
