Effect of fertilization by Cladophora algae on morphological characteristics of Vigna radiate & Sesamum indicum plants

Abstract

An experiment was done in pots at the garden of biology department, College of Science, University of Thi-Qar during September until November 2018. The experiment aimed to Know the chemical content of Cladophora sp. and it use in soil amendment as organic fertilizer, as well as its effect on some morphological characteristics (shoot and root length, shoot and root dry weight and leaf area). The experiment contained the following treatments: control ( c ) no adding algae, (1%), (2%) (3%) wich adding Cladophora sp. as( 300, 600, and 900) gm / 30 kg soil respectively. All Cladophora sp. treatments showed significant increase in all morphological characters compared with the control. (3%) treatment gave significant increase as compared to other treatments in(shoot and root length, shoot and root dry weight, leaf area and grains number) in both plant. Vigna radiate showed increasing in total length, total dry weight and leaf area (34.6 cm, 35.5 gm and 79.1 cm2) respectively in T3(3%).As for Sesamum indicum, it also showed significant differences in morphological characteristics in all the treatments and the highest values in (shoot and root length, shoot and root dry weight, leaf area and grains number) was (129.9 cm, 28.8 gm and 67.2 cm2) respectively in T3(3%).
