The experiment was carried out in a plastic house belonging to the Department of Horticulture and
Landscape of the College of Agriculture - University of Karbala for the 2021 growing season to study
the effect of spraying with marine lichen solution and the export process on the growth and yield of
tomato (Wjdan variety). The treatments included five concentrations of the organic nutrients marine
lichens 0, 50, 100, 150 and 200 ml. Liter-1 for the first factor, while guaranteeing the factor or the
procedure or not to make the Plant Hilling. The experiment was carried out in a randomized complete
block design (RCBD), as a factorial experiment with three replications. The results showed that
spraying SW extract had a significant effect on the characteristics of vegetative growth and plant
yield. The best rate of plant yield was in the spray treatment with a concentration of 200 ml. L-1
which led to 2.138 kg. Plant-1
, compared to the control treatment (spraying with distilled water),
which led to 1.492 Kg. plant-1
. The results also showed that the plant earthing up process had a
significant effect on the vegetative growth and yield characters, which was 1.956 Kg. plant-1
in the
hilled plants, while the non-earthing up plants gave 1.815 kg. plant-1
. In general, the best results of the
yield were in the treatment of the interaction 200 ml.L-1
SW and plant earthing up, which led to the
highest yield of 2.152 Kg.plant-1
compared to the yield of non-earthing up and DW sprayed plants
which resulted in 1.235 Kg. plant-1
