Effect of seed enhancement treatments on storability of cotton seeds [Gossypium hirsutum (L.)]

A study was conducted to assess the storage behavior of quality enhanced seeds of cotton. Two varieties of cotton viz. H-1226 and H-1117 constituted the experimental material for the study. Twenty five different seed enhancement treatments were investigated for their efficacy in enhancing the vigor during storage and to identify the potential treatment/s for enhancing vigour during storage. The treated seeds were stored for the period of six months under ambient condition and evaluated at three months interval for first count, germination (%), seedling length, seedling dry weight and vigour. The present studies revealed that the variety H-1226 showed relatively higher vigour compare to H-1117 with respect to seed treatments. Among all the seed enhancement treatments, Royalflo @ 5ml/kg and Thiram @ 2gm/kg + Imidachloprid @ 7.5ml/kg were found to maintain significantly higher first count, germination (%), vigour index I and vigour index II as compared to control after 6 months of storage.
