Figure 1. Details of experimental treatments and their combination. Nitrogen treatments were made with equal proportion of KNO3 and NH4Cl.
The relative growth rate of total dry weight (RGRB), relative growth rate of stem length (RGRSL), stem weight ratio (SWR), root weight ratio (RWR) and leaf specific area (SLA) were calculated using the equation shown in Table 1.
