Table 3 Analysis of variance for morphological indices including plant height (PH), leaf area index (LAI), shoot biomass (SB), crop growth rate (CGR), average tuber weight (ATW), tuber diameter (TD), and tuber yield (TY) in the field-grown potato cv. Sutlej sprayed with two different antifrost chemicals (0.5 mM salicylic acid and 100 mM potassium nitrate) in comparison to the control.
