The present study was carried out in three varieties viz., AV-5 (G1), PKB-6 (G2) and PKB-4 (G3) which were foliar sprayed with panchagavya concentration of  0 % (P0), 2.5 % (P1), 5 % (P2) and 7.5 % ( P3) at 30 days DAS for analysing the varietal differences and proper concentration of panchagavya during seed deterioration by subjected them to accelerated ageing at temperature 41±1 0c and 95 per cent relative humidity for 0 to  10 days. Various physiological and biochemical parameters were explored. It was clearly revealed that irrespective of the treatments, a progressive decline in germination, seedling length and vigour was observed due to ageing However, the EC was continued to increase towards the end of ageing which was negatively correlated with these three phenomena. The decline in germination, seedling length, seedling vigour index and increased electrolytes leakage after 6 days of accelerated ageing clearly suggested that ageing is certain to occur. However, the treatments variations in declaim of seed quality with progressive ageing had also been noticed. Interaction (G1P2) genotype AV-5 and panchagavya at 5 % concentration recorded higher seed quality parameters in initial day of ageing test and gradual decrease up to 5 days, later it decreased at higher rate at 10th day of ageing test but per cent decrease was low compared to other treatments. significantly minimum electrical conductivity and seed infection at initial day of ageing test as ageing period increases, increase in these parameters at lower rate up to 5 days after that increase in faster rate  were noticed   at the end of 10th days, but per cent increase was low in this treatment compared to other treatments.
