Lath trail was laid out at Department of Horticulture and Landscape, College of Agriculture, University of Anbar during growth season of 2018, to investigate the effect of Whey with three levels of (0, 250 and 500 ml L-1 distilled water) and Banana fruit pulp extract with three levels of (0, 25 and 50 ml L-1) on vegetative growth of Khastawi olive transplants. Eighty-one identical saplings as possible were chosen (27 saplings for each replicate). The two study factors were added at the (1/4, 1/6, 1/8 and 1/10). A factorial experiment was carried out in two factors (3×3) by R.C.B.D. design included 9 treatments replicated three times, using three transplants for each experimental unit. Applying the Whey was significantly affected all the studied traits of the vegetative growth of olive transplants (except the leaves dry weight percentage), especially the highest level (W2) which showed the best values for traits (increased of shoot number 16.52 shoot transplants -1, shoot length 23.8 cm, increased of leaves number 169.7 leaf transplants -1. While W1treatment achieved highest value for leaves area as it reached 978.89 cm2. The highest level of Banana fruit pulp extract (P2) was the best by giving the highest significant effect for all traits (increased of shoot number, shoot length, increased of leaves number, leaves dry weight percentage and leaves area) which gave 16.63 shoot transplants -1, 22.3 cm, 168.2 leaf transplants -1, 60.98% and 1013.23 cm2, respectively. The interaction between the two factors reached a significant level for the traits (increased of shoot number, shoot length and leaves area).
