The higher rhizome weight in wider spacing may be due to better nourishment and availability of space, which leads to higher weight of mother, primary and secondary rhizomes. Govind et al.(1993) also reported that maximum yield plant -1 was recorded in 30 cm x 30 cm spacing and the lowest yield plant -1 was recorded in 30 cm x 10 cm at Barapani (Meghalaya). Similar results were also obtained by Singh et al. (1988), Rashid et al.(1996) and Shashidhar & Sulikeri (1996). The effect of different plant densities on oil content and curcumin content of turmeric was non-significant (Table 5).
