A study was carried out in a plastic house for a palm date research unit/agriculture college/university of Baghdad (Abu Ghraib). During the season 2013-2014, to study the effect of spraying extract organic material and applying Humic acid and there interaction in the strawberry vegetative growth. The study include 12 treatments, to spray strawberry's plant with four levels from the extractions of organic matter (Distilled water, one volume of extracted organic matter to one volume of Distilled water 1:1, one volume of extracted organic matter to two volume of Distilled water 1:2 and one volume of extracted organic matter to three volume of Distilled water 1:3 just or with applied of three concentration of Humifert-ultra 0, 2.5, 5 ml.l-1 to the soil. A factorial experiment carried out at randomized completed blocked design (RCBD) with three replicates, Averages were tested with LSD at 5% level of probability.
The important result were found when the plants significantly at 2:1 level's was reached 3.85cm comparing with 2.478cm of plant's control. While the treatment 1:1 give the longest of runner's length were reach 130.875cm comparing with 77.394cm of plant's control, while the treatment 3:1 record highest numbers of crowns, runners and one leave distance were reached 3.792crown.plant-1,6.645runner.plant-1 and 76.423cm2 sequentially comparing with control's treatment that reach 2.737crown.plant-1,2.448 runner.plant-1 and 53.359cm2 sequentially. The additions of Humic acid were increased the plant's height and crowns number's significantly reaches 3.465cm, 3.783crown.plant-1 sequentially at 5ml.l-1 level. While the control was reached 3.199 cm and 2.496 crown. plant-1 sequentially.
While the plants were treated with 2.5ml.l-1 superior on other treatments gives greater crown diameter reach 43.937 mm while control treatment was 32.503mm. there were significantly effect to the two factors of the studies traits, the treatment H2.T1 give higher average of plant height's reach 4.510 cm, the treatment H0.T2 longest runner reach 143.124 cm and the crown diameter reach 62.551mm at H1.T0 treatment's superior significantly comparing with control treatment's that give 22.131mm, the H2.T0 treatment gives highest number of crowns reaches 5.125 crown.plant-1 comparing with control treatment's that gives 1.000 crown. plant-1, the study's results show's that H0.T3 treatment was superior significantly in runners number which gives greater number of runners reach 7.823 runner. plant-1 comparing with control treatment's that gives 1.000 runner. plant-1. While the leaves area were superior at the treatment H1.T3 significantly which gives 104.623cm2 comparing with control treatment's that gives 50.210cm2 .
