 ABSTRACT

A field experiment was conducted to study the effect of priming treatments on seedling vigour, growth and yield contributing characters in groundnut under rainfed conditions. The maximum seed yield (2255 kg/ha) was recorded due to seed primed with CaCl2 2% followed by CaCl2 1% (2036 kg/ha). The seed primed with CaCl2 2% recorded the higher field emergence percentage(89.67 %), plant height (39.87 cm), number of pods per plant (27), and 100 seed weight (38 g) followed by CaCl2 (1% ). In case of flowering and maturity, the seeds hydrated with CaCl2 2% had earlier for flowering and maturity than control. Regarding seed quality parameters viz., germination percentage (94.17%), root length (12.28cm), shoot length(18.41cm),total seedling length (29.10 cm) and vigour index I(2739.41), were enhanced by seeds primed with CaCl2 2% followed by CaCl2 1% . In case of electrical conductivity of seed leachate, the seeds hydrated with CaCl2 2% recorded lower electrical conductivity   (0.411dsm-1) than unprimed seeds.

Key words: Groundnut, Seed priming, Seedling vigour, Seed quality and Kernal yield.
