Seed priming is a process in which seeds are pre-soaked in solution to exhibit faster and
more synchronised germination and vigorous plant growth. In this study the effects of seed
priming treatments on seedling growth, fruit and yield parameters were investigated. Seeds
were subjected to four priming agents namely hydropriming (distilled water for 12 and 24
hrs), halopriming (1% KCl for 12 and 24 hrs), osmopriming (5% PEG 6000 for 12 and 24 hrs)
and hormonal priming (50% GA3 for 12 and 24 hrs) along with control (dry seed) comprising …

Among the treatments osmopriming 5 per cent PEG 6000 for 24 hrs showed best results in all the growth, yield and quality parameters followed by halopriming with 1 per cent KCl for 12 hrs. Economics analysis was also calculated and found highest B:C (4.25) in osmopriming 5 per cent PEG 6000 for 24 hrs. Whereas lowest B: C was recorded in control (4.07).
