SUMMARY
The study was conducted to analyze the effect of biostimulants treatment on the seed
quality parameters of biofortified pearl millet hybrid HHB 299 and its parental lines (A line ICMA04888,
B line ICMB04888 and R line H13/0001) at CCS HAU Hisar during 2024. The results revealed that
seed treatment with different biostimulants viz., Seaweed extract @ 100ml/kg, Gelatin @ 1%, Chitosan
@ 5g/kg and Biomix @ 100ml/kg significantly influenced the germination, seedling length, radicle
emergence, seedling dry weight, and vigour indices of HHB 299 and its parental lines over untreated
seeds. However, seaweed extract @100 ml/kg resulted in maximum increase in germination percentage
along with other seed quality parameters. Priming with Seaweed extract @ 100 ml/kg seeds for 6
hours with one and a half volume of solution at 36° improved the germination of A line by 11.54 %,
B line by 7.94%, R line by 10.56% and HHB 299 by 10.00% over unprimed seeds. Hence, seaweed
extract @ 100ml/kg is very effective for seed priming in saline-affected areas to ensure better
germination and seedling establishment of pearl millet.
