ABSTRACT

A ploy tray experiment was conducted with different rooting media and raised sugarcane seedlings at RARS, Anakapalle with RBD of four replications during sugarcane cropping season of 2014-15 and 2015-16. The results of the experiment revealed that the seedling vigour index (SVI) of sugarcane was better with the sugarcane seedlings raised in rooting medias of coir pith + vermi compost (1:1) (T1) + Urea 5 kg per 100 kg media (SVI 37.95), T1 + Sett dipping with 10% lime solution (SVI 33.36) and T1 + Sett treatment with GA3 100 PPM (SVI 30.46). The seedlings performed better with high seedling vigour index which can sustain well under transplanted conditions / fields. The additional nourishment through Nitrogen in Urea, Calcium content of 10 per cent lime solution and plant growth substance (GA3) helped in the respective treatments for better seedling vigour index over other treatments studied.
