An experiment during the two seasons 2019,2020.The experiment was conducted according to Split Plot Design by two factors, the first was addition Nano NPK with five levels (control, addition 7.5 g.plant-1 , addition 15 g.plant-1 , spray 1 g.L-1 , spray 2 g.L-1 ) symbolized (N0,N1,N2,N3,N4) respectively, and the second factor was four levels of Un Nano (mineral) NPK which were (control, 50 g.plant-1, 100 g.plant-1 , 50 g.plant-1+1.5 g.L-1 ) symbolized (A0,A1,A2,A3) respectively. Result showed that N3 increased leaves content of K, Fe, Mn, in both seasons and Zn in first season, N4 increased leaves content of N, P, and Zn in second season. Mineral NPK A3 treatment increased N, K, Fe and Zn in both season. A2 treatment increased Mn and P in both seasons.
