The experiment was conducted in Seed science post Graduate Laboratory, Department of Genetics and Plant Breeding, SHUATS, Allahabad, U.P. In order to standardize the best method of Organic priming specific to Sorghum, to evaluate the effect of different seed priming techniques on germination and morphological characters of sorghum an experiment was conducted in 2017-18 in a experiment based on the complete randomized block design with two variety M35-1 (Maldandi) and SPV 1411 (Parbhani Moti) Seed priming is a technique which improves the germination and early growth under prevailing environmental conditions. Organic priming they were evaluated by screening a range of durations and concentrations viz., T0 - Unprimed Control(for 08 hrs),T1 - Parthenium Leaf Extract 3%, T2 – Neem Leaf Extract 3%, T3– Custrad leaf extract at 3%, T4 – Calotropis leaf extract (CLE) at 3%, T5 – Panchgavya 3%, It found that all the Organic priming methods showed significance difference with the control and the highest germination %, seedling length (cm), seedling fresh weight (g), seedling dry weight (g) and vigour index were observed in Custrad Leaf Extract @3% followed by Panchgavya @3% similar trend was also observed in all treatment. Among the treatments Calotropis leaf extract (CLE) recorded minimum. and Custrad Leaf Extract @3% was found to be the best priming treatment. Moreover priming treatments have more pronounced effect SPV 1411 maintained highest quality parameters followed than M35-1 of sorghum seeds. The study helps to improve the quality of seeds with the help of seed organic priming treatments which are cost effective and economic, nontoxic, ecofriendly sources.

Key words: Calotropis leaf extract, Custard leaf extract, Neem Leaf Extract, and Panchgavya, Parthnium leaf extract, Seed priming, Sorghum seed.
