Influence of polymer seed coating, Nano nutrient and packaging materials on storability of hybrid rice KRH 4

Abstract

A storage experiment was conducted to understand the effect of polymer, containers and seed treatment on storability of hybrid rice KRH 4. The observations were recorded on characters viz, germination (cm), root length (cm), shoot length (cm), and electrical conductivity (µS ppm-1)of seed leachate after 2 months of duration for 16 months of storage. The results show that the treatments of seed stored in supergrain bag for 16 months recorded significant higher percentage of germination (85 %), root length (22.4 cm), shoot length(12.9 cm ), electrical conductivity (83.10 µS ppm-1) and Total dehydrogenase activity(0.83 A480) as compared to other treated seeds were stored in jute bag. Germination percentage decreased with the period of ageing. Seeds are stored in plastic bags were affected due to storage but the effects were more pronounced in the plastic bags as compared to jute bags. These result indicates that the seeds packed in supergrain bag were good in seed quality characters.
