An Assessment of Cosplay of Microbes Treated Seeds on Storability of Rice Seeds

Background: Warm, humid weather can hasten the deterioration of seeds in the context of sustainable agriculture due to changing climatic circumstances. For rice, therefore, ideal growing conditions are incompatible with storage conditions. Thrissur’s tropical environment makes seed storage in warehouses after harvest particularly difficult. In order to determine the impact of various seed priming treatments on the longevity of seeds under accelerated ageing, the current study was undertaken. Methods: Rice seeds of variety Jyoty were treated with Pseudomonas florescens (10 g/kg), Trichoderma viride (4 g/kg) and coconut water 75% in different combinations. Treated seeds were packed in butter paper bags with pin holes to absorb moisture for ageing and placed in the wire gauge/mesh above the water well such that seeds are not in touch with water inside BOD incubator from 0 to 7 days and received a temperature of 40±1oC and a relative humidity of 98%. Accelerated aged samples were taken at daily intervals and subjected to further tests to determine its quality and longevity. Result: At the end of the ageing period, coconut water (75%) and P. fluorescens (10 g/kg) + T. viride (4 g/kg) + coconut water (75%) recorded the longest root length (14.12 cm and 14.09 cm, respectively) and was on par with T. viride @4 g/kg (13.78 cm), coconut water treatments (T7 14.94 and T3 14.32) have shown early emergence. Furthermore, dry dressing with bio agents has been found superior in performance compared to wet treatments under accelerated ageing.
