| Abstract | ||
| Effect foliar spray with three levels of seaweed extract kelpak40 (0, 2 and 4 ml.L.1) and iron (0.20 and 40 mg Fe.L.-1) using chelated iron Fe-EDDHA (6% iron) and the interaction between them on the growth of loquat seedlings, one year old which were planted in the lath house/ Horticulture and Landscape Design Dept./College of Agriculture and forestry/ Mosul University at 2011 growing season were studied. Results showed that the interaction between 2 ml.L.-1 kelpak40 + 20 mg Fe.L.-1 significantly dominated over control treatment in leaves number, seedling leaves area and leaves dry weight percentage which reached in this treatment 16.66 leaf/seedling, 1262.90 cm2/ seedling and 43.05% respectively, while the means of these parameters in the control treatments were 9.5 leaf/ seedling, 534.60 cm2/ seedling and 35.21 respectively. The interaction of 4 ml.L-1 kelpak40 + 40 mg Fe.L.-1 were dominated over control treatment in leaf area and leaves dry weight which reaches 81.05 cm2 and 7.70 gm. respectively in this treatment and 55.71 cm2 and 5.25 gm. respectively in control. while the treatment of 4ml.L.-1 kelpak40 was dominated over control in seedling length and leaves total chlorophyll, which reaches 33.66 cm and 59.20 SPAD in this treatment and 22.66 cm and 56.16 SPAD respectively in control. The interaction between 2 ml.L.-1 kelpak40 + 40 mg.L-1 chelated iron were dominated over control in leaves N and Fe concentration which reaches 1.48% and 710.33 mg.L-1.in this treatment and 0.73% and 431.67 mg.L.-1. Respectively in control. | ||
