دراسة تأثير حامض الهيومك و عنصر الحديد في بعض الصفات الخضرية لنبات الشبنت Anethum Graveolens L

Abstract EN

Experiment was in green house of Department of Horticulture and Garden Engineering, Faculty of Agriculture and Marshland, University of Thi Qar, Iraq.

In 2018- 2019.

For tested effect of adding Humic acid and Iron on some growth vegetative characteristics of dill (Anethum graveolens L.

).

Two factor were tested (Humic acid and Iron), in three levels were tested humic acid (H0 control, H1= 50% concentration and H2= 75% concentration) respectively.

Iron (F0 control, F1= 4 grams/ pot and F2= 6 grams/ Pot) respectively.

Plantlets were planted in plastic pots with three replications.

A Study included twenty-seven experimental units in loam Silt soil by using the RCBD design.

A study confirmed superiority of H2 level over the rest of the humic acid treatments (H0 control, H1) in plant height, branches number, plant wet weight, plant dry weight and chlorophyll content, with recorded an average of (27.76 cm, 9.00 branch/plant, 20.14 g /plant, 4.429 g/ plant and 1, 293 mg / L)respectively.

Also a study confirmed superiority of F1 level over the rest of Iron treatments (F0 control, F2) in plant height, branches number, plant wet weight and chlorophyll content, with recorded an average of (27.73 cm, 8.96 branch/plant, 20.35 g /plant, 362 mg / L) respectively.

While F2 treatment was superior to average plant dry weight only (4.41 g/ plant).

In interaction between (Humic acid and Iron) factors, a study confirmed superiority of H2F1 level over the rest of treatments in plant height, branches number, plant wet weight and chlorophyll content, with recorded an average of (33.80 cm, 12.47 branch/plant, 24.43 35 g /plant and 614 mg / L) Experiment was in green house of Department of Horticulture and Garden Engineering, Faculty of Agriculture and Marshland, University of Thi Qar, Iraq.
