Abstract 

An experiment was conducted in a completely randomized design with four replications during rabi, 2020-2021at seed testing laboratory of the department of genetics and plant breeding, Sam Higginbottom institute of Agriculture Technology and Science, Prayagraj, Uttar Pradesh. Genetically pure sorghum seeds var Nutra white was used for the experiment. Sorghum seeds treated with Neem leaf extract 5% @ 1 hr, Neem leaf extract 5% @ 3hrs, Neem leaf extract 5% @ 6hrs, Tulsi leaf extract 5% @ 1hr, Tulsi leaf extract 5% @ 3hrs, Tulsi leaf extract 5% @ 6hrs, Neeem+Tulsi leaf extract 5% @ 1hr, Neeem+Tulsi leaf extract 5% @ 3hrs, Neeem+Tulsi leaf extract 5% @ 6hrs, Moringa leaf extract 5% @ 1hr, Moringa leaf extract 5% @ 3hrs, Moringa leaf extract 5% @ 6hrs,  and stored in different packaging materials (polythene bag, aluminium foil & cloth bag) were subjected to germination studies in laboratory, seed germination and growth parameters were recorded. The highest germination percent (93.73%), root length(10.87), shoot length(17.02), seedling length(27.90), fresh weight(1.14),dry weight(0.28), vigour index-I(2616), vigour index-II(27.06) was observed in Neem+Tulsi leaf extract 5% @ 6hrs, stored in polythene bag, followed by Neem leaf extract 5% @ 6hrs significantly whereas lowest found in control . Polythene shows maximum result followed by aluminium foil pouch; cloth bag shows minimum performance.  Polythene bag is suitable  for storage of sorghum seeds and cloth was found not suitable for seed storage.

Key words: Moringa, Tulsi , Neem, leaf extracts, Polythene bag , Aluminium foil pouch, Cloth bag.
