e0“growth of `TI-155' sweetpotato [Ipomoea batatas (L.) Lam] was evaluated in a greenhouse”
e2“Storage root fresh and dry weights, growth rate (g m -2 d -1 ), fibrous root dry weight, foliage fresh and dry weights, and edible biomass index (root mass/total plant mass), though not significant all increased as K was increased in the nutrient solution”

- Intervention effect Increasing K in the nutrient solution linearly increased the number of storage roots per sweetpotato plant.
- Intervention effect Increasing K in the nutrient solution increased fibrous root dry weight and foliage fresh and dry weights, though not significantly.
- Intervention effect Increasing K in the nutrient solution increased the edible biomass index of sweetpotato, though not significantly.
- Intervention effect K uptake was greatest in sweetpotato plants at the highest K level.
- Observation Nitrate uptake by sweetpotato was steady over the crop growth regardless of treatments.
