Effect of Planting Dates In Some Vegetative Growth Characteristics of Three Varieties Broad Bean (Vicia Faba) Cultivated In Iraq

A field experiment was conducted at the university of Kirkuk /college of agriculture/al_hawija during the winter season of 2021-2022. The objective knowledge effect of two planting dates (11/14 and 11/28) on some growth traits of three varieties of Broad Bean (local, Spanish, and holand Dolce star.(The experiment was Applied according to a completely randomized block design as a factorial experiment with three replicates. The studied Growth traits were plant height (cm), number of vegetative branches (branch.plant-1), number of leaves (leaf.plant-1), number of nodes (node.plant-1), and Phalangeal length (cm).The data were analyzed statistically and the results showed that significant differences between the planting date treatment, as the second date excelled in all the studied traits. It was also noted that significant differences between the varieties in all the studied traits, as the Dutch variety excelled in the two traits of plant height (42.83cm) and the Phalangeal length (7.07 cm), while the Spanish variety excelled in the number of leaves (25.00 leaf. plant-1) and the number of nodes (8.97 node.plant-1), while the local variety excelled in the number of vegetative branches (6.93 branch. plant-1). The interaction between the study factors was significant for all the studied traits, as the Dutch variety excelled with the second planting date in the plant height (52.00 cm), while the Spanish variety excelled with the second planting date in the number of leaves (29.67 leaf.Plant-1) and the number of nodes (9.93 node.Plant-1) and the Phalangeal length (cm), while the local variety with the second planting date excelled in the number of vegetative branches (9.93 branch.Plant-1) and the Phalangeal length (7.63 cm), while the local variety with the second planting date excelled in the number of vegetative branches (7.00 branch.Plant-1).
