Abstract

A field experiment was carried out in winter season of 2015-2016 in department of field crops farm-Agriculture college- Anbar University (alternative site) in Abu Ghuriab, to study the effect of spraying with different concentration of pyridoxine (Vit B6) 0, 100, 200 B6 mg L-1 in growth and yield of four broad bean cultivars (Spanish, Holland, Italic and local variety). The experiment was conducted in split plot arrangement in Randomized Complete Block Design RCBD where the main plots were occupied by cultivars while the sub plots were occupied by pyridoxine concentrations. The results were summarized as follows:
The increment in B6 concentration 200 mg B6 L-1 led to increment in most studied traits namely: plant height 75.19 cm, leaf area 3542 cm2, 100 seed weight 141.07 gm, seed yield 6.025 ton ha-1, protein yield 1.4 ton ha-1 and biological yield 10.613 ton ha -1 . The Holland variety achieved highest in plant height 93.47 cm, leaf area 4145 cm2, while Spanish variety achieved highest in weight of 100 seed 166.36 gm. and Italic variety achieved highest in number of seed in pod 5.89 seed pod-1, seeds yield 6.371 ton ha-1 , protein yield 1.501 ton ha-1 and biological yield 12.189 ton ha-1.
