Effect of Foliar Application of Algaren and ALG6000 on Growth and Chemical Characteristics in Two Cultivars of Broad Bean (Vicia faba L.)

Abstract

A field experiment was carried out in Nineveh Governorate during the winter season of 2018-2019 to study the effect of spraying with seaweed extracts Algaren and ALG6000 on some vegetative, root, qualitative and mineral growth characteristics of leaves and dry seeds of two cultivars of broad Beans. The study included eighteen treatments in each replicate, consisting of a control treatment (without any addition) and spraying with four levels of seaweed extract Algaren (2, 4, 6 and 8 cm3.l-1) as well as Four-level spraying of ALG6000 seaweed extract (2, 4, 6 and 8 cm3.l-1) on two broad bean cultivars. Algaren achieved the best value over ALG6000 in the studied traits. The French cultivar Aquadulce recorded better results than the Spanish cultivar Luzde Otono, with a dry root weight, leaf area, and nitrogen and phosphorous content of protein and carbohydrates in the dry seeds. In contrast, the Spanish bean variety Luzde Otono recorded the highest significant value in a number of root nodes, the content of leaves and dry seeds of potassium.
