Effect of organic fertilizer addition and spraying seaweed extract on some growth characters, yield and active ingredient of arugula plant (Eruca sativa Mill)‎

Abstract EN

The experiment was conducted at the horticulture and garden landscape department field/college of Agriculture/ Tikrit University in Salah Alden area, at the growing season of 2016-2017, to study the effect of organic fertilizer (mushroom culture wastes composites), addition and spraying of seaweed extract (Algamex) on arugula plant (Eurica sativa Mill.) and effect of vegetative growth, yield, and active ingredient.

The experiment included 24 experimental units results of combination of experimental factors.

The first factor was addition of mushroom culture wastes (composites) at a percentage of 10% calculated on experimental unit size, in addition to the control treatment (no addition).

The second factor was spraying with seaweed extract with three levels in addition to the control treatment (no spraying), as followed: B1 sprayed with water only, B2 2.0 ml.

liter-1 seaweed, B3 4 ml.

liter-1, and B4 6 ml.

liter-1 with their combinations.

The experiment planned and analyzed on Randomized Complete Block Design at three replications.

The results were compared used Duncan’s multi-variance at probability level of 0.05.

The results were; the addition of mushroom culture waste was dominated in most of the study compared with control treatment (no addition).

The spraying treatment of 6 ml.

liter-1 was dominated to get the highest results of the plant height feature.

The combination was significantly clear with 10% addition and spraying with 6 ml.

liter-1 to give the highest values of studied features including plant height, leaf number, fresh weight, dray weight, leaf area, total yield as the means were 45.00 cm, 53.33 leaf.

plant-1, 213.10 gm.

Plant-1, 49.80 gm.

Plant-1, 113.40 cm2, and 2.59 kg.

experimental unit-1 respectively, compared with other treatments.

The correlation results gave a positive correlation between the studies features.

There was positive effect of the secondary production in the plant; as the combination of 0.0 composite + 4 ml.

liter-1 gave a highest concentration of Resorcinol compound 0.14%.

The treatment of 10% + 4 ml.

liter-1 gave the highest value 0.042% of Catechol.

The treatment of 10% + 0.00 gave the highest value 0.136% of Ascorbic acid.
