ABSTRACT
Organic seed is a crucial link in the chain from research to organic seed production and ultimate supply of high quality seed at reasonable price to the commercial seed producing farmers for promotion of organic cultivation. Hence, the laboratory experiment was to find out the effect of organic seed treatment on seed quality of maize seeds treated with sixteen organics with different concentrations during storage. The results revealed that maize seeds treated with vermiwash @ 2 per cent recorded significantly higher germination percentage (87.67%), seedling vigour index (2037), dehydrogenase enzyme activity (0.462 OD value) and lower seed moisture content (11.95%) and electrical conductivity of seed leachates (0.396 dSm-1) at the end of nine months of storage period.
