    Effect of seed treatments on seed quality of onion (Allium cepa L.) during storage
    (CCSHAU, Hisar, 2021-10) Rathi, Prashant; M.S., Puneeth Raj
    The present investigation was carried out at the Department of Seed Science and Technology, CCA Haryana Agricultural University, Hisar to assess “ Effect of seed treatments on seed quality of onion (Allium cepa L.) during storage”. The seeds of onion (Cv. HO-3) was treated with neem oil, nano particles, thiram and chlorpyrifos along with their combinations and stored. Secondly seeds was primed with ethanol, water, GA3, nanoparticles and Trichoderma after 10 months of storage period. All the treatments was evaluated for seed quality parameters viz. test weight (g), standard germination (%), speed of germination, seedling length (cm), seedling dry weight (mg), vigour index I & II, electrical conductivity (μS/cm/g), catalase activity (μmoles/min/g), dehydrogenase activity (ODg-1ml-1), peroxidase activity (μmoles/min/g), superoxide dismutase activity (IU/g F wt). Results revealed that seeds treated with T12 – Chlorpyrifos 20 EC + Thiram + ZnO Nano particles were found significantly higher in seed quality parameters followed by T8 - Neem oil + ZnO nano particles + Chlorpyrifos and least was found in control . Secondly seeds primed with ZnO (100 ppm) nano particles were found superior in most of seed quality parameters followed by ZnO (200 ppm) nano particles followed by T9 – ZnO (200 ppm) nanoparticles and least was found in T1 - control
