Abstract: The objective of this research was to evaluate assessment of vegetative growth and leaves oxalate contents in three sweet potato varieties. The experiment used a factorial experiment in a completely randomized design (factorial in CRD). Factor A consisted of three sweet potato varieties : Purple Sweet Road, Purple Okinawa Beni Imo, and Kuri Beni Imo. Factor B included four levels of sweet potato days of transplanting : 30, 60, 90 and 120 days; a treatment including four replications. Data on main vine length, number of branches, leaf fresh weight, leaf dry weight, chlorophyll fluorescence, leaf area, specific leaf area, and oxalate content were recorded. The results showed that the cultivars and days after transplanting interacted to affect growth. The Purple Okinawa Beni Imo cultivar at 120 days after transplanting had the highest vine length, fresh leaf weight, and leaf dry weight, as well as the highest chlorophyll fluorescence (0.74). However, in terms of branch number per plant, the Kuri Beni Imo cultivar had the highest number of branches per plant (17 branches) at 120 days after transplanting. Assessment of oxalate content in sweet potato leaves found that the Purple Sweet Road cultivar at 30 days after transplanting had a high oxalate content of 165.63 mg/g FW. This was followed by the Purple Okinawa Beni Imo cultivar and the Kuri Beni Imo cultivar at 30 days after transplanting. This study suggests that the Purple Okinawa Beni Imo and Purple Sweet Road tend to adapt well to growth conditions. If one consumes sweet potato leaves, it is advisable to avoid the sweet potato stage at 30 to 60 days after transplanting to reduce the risk factors associated with developing urinary tract stones.
