This experiment was conducted at Al-Sadat Experimental Farm of the Faculty of Agriculture, Al-Azhar University, Monoufia Governorate, Egypt, during the two consecutive growth seasons of 2017/2018 and 2018/2019 to evaluate the effect of different irrigation water levels, (60, 80, and 100%) of evapotranspiration crop (ETc) on growth, yield and pod quality of green bean cultivar Joya under the plastic greenhouse conditions. The obtained results showed that there were significant differences among the three levels of irrigation for the most tested parameters. It was obvious that irrigation water level at 100% of ETc significantly increased pod weight, length and diameter, in addition to stem internode length and leaf relative water content, as well as leaf fresh weight and area. Likewise, this irrigation level increased total pod yield in weight and in number of pods per plant and total protein content, while the lowest level of irrigation (60% of ETc.) improved some quality characters such as total chlorophylls, proline contents in leaf, total soluble solids, ascorbic acid, total sugars, and crude fiber contents in pods.
