Two field experiment were carried out during the two successive winter seasons of 2017-2018 and 2018-2019 in a private sector farm at Damalo Village, Qalubia Governorate, to investigate the effect of three mineral fertilizer levels (100,80 and 60% of recommended dose of NPK) as soil application and foliar spray with two different sources of NPK applications (NPK in 20:20:20 form, NPK in nano form and control) on vegetative growth, chemical composition and productivity as well as pod quality of snap bean (Phaseolus vulgaris L.) cv. moraleda. This experiment included 9 treatments resulted from the interaction between three NPK levels (100,80,60% of recommend dose) with three foliar applications (NPK in20:20:20 form, NPK in nano form and control). A split plot design with three replicates was adopted. Obtained results showed that, fertilizer snap bean plants with 100 and 80% of recommended dose of NPK as soil application with sprayed plants with nano NPK at 2ml/l for each element reflected the highest values in all studied vegetative growth characters, chemical constituents of plant foliage and pod yield and its components and chemical pod quality .
