Abstract

Priming is one of the pre sowing seed management technique recommended for better field emergence. In the present study, fresh seeds were haloprimed with 10 and 15 per cent of KNO3 , NaCl and osmoprimed with -1.0 and -1.5 bars PEG solution for 24, 36 and 48 h for evaluation of the suitable priming technique for invigourating sesame seeds. The results revealed that halopriming with NaCl 10 per cent for 48 h followed by NaCl 15 per cent for 24h improved the seed and seedling quality characters. Upon storage the primed seeds recorded 88 per cent germination upto 4 months which was 13 per cent higher than control.
