| Abstract | ||
| The study was conducted at Erbil Governorate/ Iraq at the agricultural season 2015 on Cress ( Lepidium satirum) and Aloe ( Aloe vera). Factorial experiment with two factors: Humic acid (H) with three Levels: H0 (without Humic acid addition), H1 (drench with 1 ml.-1 of Humic acids , H2 ( spraying with 1ml. L.-1 of Humic acids). Second factor was sea algae extracts (S) with four Levels: S0 (without spraying), S1(spraying with 1.5ml. L-1 of seaforce1 sea algae extract), S2 (spraying with 1.5 ml. L-1 of seamino, sea algae extract), S3 (spraying with a mixture of 1.5 + 1.5 ml.L-1 of seafore1 and seamino sea algae extracts). Experiment designed with RCBD,for three replication.Results showed that, Addition of Humic acid and sea algae extracts to the Cress and Aloe Vera causes to significant increase in the whole vegetative growth characters. The Interaction between Humic acid and sea algae extracts caused significant increase in the whole vegetative growth characters; the Garden Cress that were sprayed with Humic acid and a mixture of seafore1, seamino gave highest values of plants high (16.31cm.), leaves number per plant-1 (57.86)lef.plant-1, plant Branches number. (9.30) orenh plant-1 , Leaf area (3.82 cm2), Dry weight (3.10 g. plant-1) and Chorophy1l(36.80SPAD) as. Whereas with Aloe vera, the interaction between spraying Humic acid and sea algae extract caused significant increase in the whole vegetative growth characters, they gave a highest value in all vegetative growth characters, they gave a highest plant high (28.80cm), leaves number (12.93) leaf. plant-1, leaf width (2.86cm), leaf thickness (1.06 cm), Dry weight (14.62g. plant-1) and chlorophyll (34.33), compared with the lowest values in control plants. | ||
