Chitosan is a biotic elicitor and established as an effective priming agent in various crops. An experiment was conducted to evaluate the effect of priming of rhizome bits with chitosan on sprouting and plantlet development in two turmeric varieties, Sobha and Sona. 1 g, 2 g & 4 g L-1 of chitosan for 30 min and 1 h of soaking, was compared with untreated control. Chitosan treatment at the rate of 1 gL-1 for 1 h recorded significantly higher shoot weight (7.36 g and 5.27 g), root weight (1.18 g and 0.71 g) and seedling vigour index (6030.67 and 5063.61) in Sobha and Sona, respectively. The priming of rhizome bits with chitosan 1 gL-1 for 1 h recorded significantly superior performance in terms of growth parameters and seedling vigour index in both the varieties.
