Agronomic Indices Assessment for Horse bean (Vicia faba L.) based on Seed Stimulation by Gibberellin and Varieties

Background: Vicia faba L. equina belong to medium size seeds group which is considered one of the main pulse crop which are widely and mainly used it’s pods, fresh and dry seeds in cooking, especially by a large section of poor people as a source of expensive animal protein compensation. Methods: A field experiments carried out at agricultural researches and experiments station affiliate of the College of Agriculture, University of Kirkuk - Kirkuk Province, Iraq, Randomized complete block design with three replicates used to perform this experiment. For determination following seed presoaking before sowing in gibberellin (GA3) 50, 100 and 150 mg L-1 concentrations in addition to seed presoaking in tap water as control treatment and two imported horse bean varieties included Aguadulge (Italy) and French (France) variety. Result: Seed presoaking in two gibberellin concentrations 100 and 150 mg L-1 before sowing had a significant influence on plant growth and seed yield. Aguadulge variety exceeds significantly upon on French variety in most of seed yield and it is related. 100 mg L-1 gibberellin x French variety and 150 mg L-1 gibberellin x Aguadulge variety gave the highest seed yield and its components. The findings hint that seed presoaking technique before sowing in gibberellin was useful to enhancement agronomical indices of horse bean varieties, so it could be suggests that increasing gibberellin concentration up to100 mg L-1 for French variety and up to150 mg L-1 for Aguadulge variety increase the horse bean seed yield and its components.
