he experiment was conducted at the Protected Agriculture Research Station (B) at the college of Agriculture / University of Baghdad in Al-Jadriya Complex to study the effect of spraying different concentrations of humic acid (0, 75 ml, 100 L-1), Gibberellins (0, 100, 200 ppm) and Smoked water (0, 1: 250, 1: 500, 1: 1000 v/v) In the growth and yield of tomato under protected agriculture conditions for the autumn season 2017-2016.

The results showed that the treatment of Spraying with Gibberellins (G1) and Smoked water (S2) was significantly excelled in most vegetative traits, either as individual or interaction factors, as well as in the interaction effect of the humic with the Gibberellins and its interaction with the Smoked water.

Triple interaction of the factors in all the traits was excelled under study.

While no significant effect was observed for individual humic spraying treatments in any of the traits
