| Abstract | ||
| Two field experiments were carried out in two different seasons to study the effects of Fungicide seed dressing and Rhizobium inoculation on the physical properties of Vicia faba L. seeds. Two fungicides (Captan and Fernasan-D) at different concentrations 0, 2, 4 and 6 g/kg faba bean seeds in the first season and 8 and 10 g/kg faba bean seeds in the second season were used. Three methods of inoculation with Rhizobium leguminosarom bv. viceae strain TAL 1397 were carried out viz: inoculation immediately after or before fungicide seed dressing or inoculation at the seedling stage. Compared to uninoculated plants, inoculation by both methods significantly (P≤0.05) increased 100-seed weight, significantly (P≤0.05) decreased total defects percentage and cookability. No effects were observed on either soakability and hydration coefficient. No differences were detected between inoculation after or before seed dressing in all parameters and only inoculation with fungicidal seed dressing was used in the second season. Fungicide seed dressing significantly (p≤0.05) affected 100- seed weight and cookabilty depending on the fungicide toxicity and concentration, the total defect percentage was significantly (P≤0.05) decreased and resulted in a lower hydration coefficient. Captan was found to be more toxic resulting in more effects than Fernasan- D. | ||
