Abstract: This study was for evaluate the effect of packaging materials and different treatment on viability during storage. This evaluation was started in two different rice varieties was studied during October 2014 to March 2015. Two variety viz. Pusa basmati-1 (V₁), and Jaya (V₂) were equally divide into 4 lots of 2000 gm each and treated with castor oil @ 5ml/kg seed (T₁), neem cake @ 10 gm/ kg seed (T₂), Thiram @ 2gm/kg (T₃) seed alone with control (untreated T₀) and packed in vacuum polythene bags (P₁), non vacuum polythene bags (P₂), and jute bags (P₃) and maintained for 24 weeks with 12% seed moisture content under ambient conditions. The results clearly revealed that seed stored in vacuum polythene bags and treated with castor oil, variety Jaya was proved to be superior of viability (mean P₁ 83.38, T₁ 83.33 and V₂ 83.17). According to this research castor oil protective agent against seed deterioration due to fungal invasion and physiological ageing as result of which the seed viability was maintained for a comparatively longer period of time.
