A 2-Yr study was conducted at the Agricultural Research and Experiments Farm at the Faculty of Agriculture , Benha University to evaluate the effect of NPK (low , medium and high) on vegetative growth , yield and chemical content of conocarpus tree and shrubs (saligna , atriplex and adhatoda). Conocarpus tree and shrubs (saligna , atriplex and adhatoda) were fertilized with high (90:60:30 NPK kg fa-1) , medium (60:40:20 NPK kg fa-1) and low (40:20:10 NPK kg fa-1) in a split plot design where the conocarpus tree and shrubs (saligna , atriplex and adhatoda) were in the main plots , while the fertilization levels were placed in the sub plots , measurements were taken in autumn and spring during the two seasons of the study , the results show that, all data of vegetative growth , yield and chemical content gave positive results, the three levels of fertilization in both seasons under study and the increase was significant with the highest level of fertilization to obtain the highest productivity and high chemical content of the fodder conocarpus tree and shrubs (saligna, atriplex and adhatoda) and using them as non-traditional fodder.
