Efficacy of Seed Invigoration Treatments with Fungicidal Formulations for Maintenance of Physiology, Enzyme Activity and Yield of Soybean
DOI:10.30954/0974-1712.06.2018.13
Abstract:
Pre-storage seed invigoration treatments in freshly harvested soybean seeds with powdered crude plant materials (red chilli powder @1g/kg of seed), chemicals (para-amino benzoic acid and ferulic acid @500mg/kg of seed) in combination with fungicides like captan@2g/kg of seed, thiram @2g/kg of seed and bio fungicide Trichroderma viride @4g/kg of seed significantly improved germinability, field performance and productivity over untreated control. Among the treatments, ferulic acid and red chilli powder has shown better results in improving storability and field performance. Seed protectants alone did not show significant differences. But captan incombination with ferulic acid has shown higher germinability and field performance than the control and other treatments. Biochemical studies revealed that pre-storage dry treated seeds with fungicidal formulations showed the activity of dehydrogenase, catalase and peroxidase enzymes were higher in all dry treated seeds compared to the untreated control. Among the treatment, ferulic acid and red chilli powder formulated with seed protectants viz. captan and thiram has shown higher enzyme activity. On the basis of the results, dry physiological treatments, ferulic acid and red chilli powder formulated with seed protectants captan and thiram suggested for improved storability and field performance of stored soybean seed. The interaction effect between physiological treatments and seed protectants were positively correlated.
