Abstract:
The present work was conducted to standardize the seed priming duration in chia at Laboratory, Department of Seed Science and Technology, UAS, Dharwad during 2020. 20 minutes of seed priming duration recorded higher germination (91.75%), seedling length (13.53 cm) and seedling dry weight (1.03 g/ 10 seedlings),) compared to control. Another experiment was carried out to know the effect of biopriming and micronutrient priming on quality and yield parameters in chia at ARS, Bagalkot. Seed priming with Zinc (1.5%) recorded higher seed quality and growth parameters viz., germination (95.25%), seedling length (16.33 cm), seedling dry weight (1.260 g/10 seedlings), plant height (91.73) followed by Azospirillum brasiliense (20%). Seeds primed with Zinc (1.5%) showed higher yield attributing traits viz., number of spikes per plant (18.53), spike length (16.30 cm), yield per plant (15.68 g), yield per hectare (752.38 kg ha^-1) and 1000 seed weight (1.332 g) followed by PSB (20%) over control. Hence, it can be concluded that seed priming with Zinc (1.5%), Azospirillum brasiliense (20%) and PSB (20%) enhances the quality, growth and seed yield in Chia.
