Abstract:
The experiment was conducted at Department of Seed Science and Technology PJTSAU, Rajendranagar to investigate the “Effect of chemical seed treatment on seed quality and storability in maize inbreds lines and hybrids (Zea may L.)”. Freshly harvested seeds were treated with the thiamethoxam seed treatment. The seeds were stored for 8 months under ambient condition and observations were recorded on seed quality parameters bimonthly up to eight months. Among chemical seed treatment, seeds treated with thiamethoxam@ 2g/ kg of seed had better seed storability and seed quality parameters such as germination test (89%), seedling vigour index-I (2282), seedling vigour index-II (65830), electrical conductivity (10.5dSm-1), and field emergence (76%) than control 84%, 2043, 47452, 12.99dSm-1, 74% respectively. This study could be concluded that the maize inbreds and hybrids treated with thiamethoxam @ 2g/ kg were stored for a longer period. However, untreated seeds recorded lower seed quality parameters.
