ABSTRACT

The present experiment was conducted to know the impact of seed priming with chemicals on seed quality of chickpea, by subjecting seed of chickpea to various priming treatments viz., hydration, hydration followed by seed primed with 2% KH₂PO₄, 2% CaCl₂ and 100 ppm GA₃ for9 hours followed by shade drying to bring back its original moisture content. The primed seed along with untreated seed (control or check) was tested for seed quality parameters. Among priming treatments, seeds primed with GA₃ showed significantly higher seed quality parameters over other treatments. Among the genotypes, NBeG-452 was found to be superior over NBeG-119 in seed quality parameters. Among interactions, G₁T₅ (seed of NBeG-452 primed with 100 ppm of GA₃) showed significantly higher seed quality parameters like shoot length, root length, seedling length, seedling vigour index and field emergence over other interactions.
